2013 Audi Q5 Concept
Liftet 2013 Audi Q5 to be mid-size SUV. With modifications in the drive and design should consist of big brother of the Q3 compete against the BMW X3 and Mercedes GLK. The prices change significantly.
The engine line is a 2.0-liter turbo gasoline engine with 165 kW/225 hp, which replaces the previous version offered with 155 kW/211 hp. As a replacement for the aged 3.2-liter V6 petrol engine already known from other models, 3.0-liter supercharged engine is used. The six-cylinder engine delivers 200 kW/272 hp and is designed with a consumption of 8.5 liters, 0.8 liters more economical than its predecessor.
The other engines have been largely revised, are now stronger and more economical at the same time. The mean 2.0-liter diesel develops 130 kW/177 hp instead of now about 125 kW/170 hp and needs 6.0 instead of 6.2 liters of fuel. What remains unchanged is the hybrid version with 180 kW/245 hp.
The power transmission is ensured depending on engine version has a six-speed manual gearbox, an eight-speed automatic transmission or a seven-speed dual-clutch gearbox. Further technical innovation is the already introduced in the Audi A4 electromechanical steering system, which will provide greater fuel efficiency.
The visual changes are visible only at second glance. The most striking feature of the face lifted version of the bleed upper corners of the grille. In addition, there are slight modifications to the front and rear and an upgraded interior with more chrome. Also new is an optional Wi-Fi hotspot.
The prices for the model are available from late April to change only slightly. The 177-horsepower diesel costs about the future in conjunction with all-wheel drive $ 53,056.18.

In the development of the A8 series, Audi has the special protection version from the beginning taken into account - as was an integrated approach that surpasses retrofit solutions far. With 5.27 meters long and 3.12 meters wheelbase Security is visually indistinguishable from the Audi A8 L Security Series version. The base is a modified Series body. Weighs about 40 percent less than a comparable steel construction. The specific components created by hand in a protected production environment. In about 450 hours of work trained employees build a she, before the body is transported back to the factory for final assembly.
Bulletproof with certificate
The new Audi A8 L Security has the official certification of the German bombardment Office in Munich ; it meets the requirements of ballistic class VR 7 on the BRV 2009. The abbreviation BRV stands for Bullet Resistant Vehicles. In the VR 7 class the most stringent requirements shall apply in the area of civilian armored sedans : The sheet metal and glazing of the vehicle cell must withstand firing with NATO hard -core ammunition . In some areas, the armor meets the criteria of class VR 9 and VR 10 The resistance to explosions was checked according to Directive 2010 ERV (Explosion Resistant Vehicles).
In the safety cell of the special-protection saloon, which is integrated as a self-supporting component in the body , are extremely tough and durable materials are used - hot-formed armored steel , aramide fabric , ceramics, special alloy aluminum and multilayer glass. The protective materials overlap at the crossing points.

The standard features of the new Audi A8 L Security also includes the intercom, the passengers can communicate with the windows closed to the outside world . She uses a speaker in the single-frame grille as well as microphones for indoor and outdoor use.
Escape route as standard
Audi holds for the new A8 L Security many options that improve the protection on. One of them is the emergency exit system , a patented technology of the brand. When the driver or rear passenger pressing a sealed switch and remove one of the inner door handles, pyrotechnical separating screws loosen the hinges in the door from the body - this can be slight pressure to push open outwards.
Another feature is the fire extinguisher system , which is activated by pressing a key or by thermal sensor . The emergency fresh-air system operates with two pressure bottles, which are housed in the protected area . By pressing a button , it supplies the interior via vents with fresh air to breathe - in most cases long enough to pass through a danger zone or to leave. The system creates pressure in the car interior , thus preventing the penetration of toxic gases . Another option is the security start - here the driver activates the motor from a distance by radio. In addition, Audi also deals with individual special needs of its customers.
Lots of security takes a lot of power

2014 Audi A6 TDI Concept
Electric biturbo and hybridization
The TDI engine gets its power from the boost pressure developed by the turbocharger, which is dependent on the energy of the exhaust. The electric biturbo breaks this dependency. Its supplemental electric compressor enables a rapid buildup of boost pressure and high torque even at low engine speeds. 25 years after the invention of the TDI, Audi is now taking the next big step and making the diesel engine even more emotional and sporty.
In addition to the classic exhaust gas turbocharger, the electric biturbo has a second charger arranged in series. Instead of a turbine wheel, it contains a small electric motor that applies a maximum drive power of seven kW to accelerate the compressor wheel to maximum speed within 250 milliseconds.
The electric compressor is downstream of the intercooler. At very low engine speeds and thus correspondingly low exhaust gas energy at the turbocharger, the bypass valve closes and the air is routed to the electric compressor. This can be flexibly and compactly integrated into a variety of forced induction concepts.
Audi has built two technology studies with the electric biturbo: The Audi A6 TDI concept is equipped with the new 3.0 TDI monoturbo; the Audi RS 5 TDI concept with the 3.0 TDI biturbo. In steady-state – no additional impetus – the monoturbo produces a constant 240 kW (326 hp) and 650 Nm (479.4 lb-ft) of torque, the latter between 1,500 and 3,500 rpm. The electric compressor fills the gap in the torque curve below this range and provides for fast response and excellent elasticity. Acceleration from 60 to 120 km/h (37.3 to 74.6 mph) in sixth gear is reduced from 13.7 to 8.3 seconds.
The modified V6 biturbo in the Audi RS 5 TDI concept is even more impressive. It produces 283 kW (385 hp), and peak torque of 750 Nm (553.2 lb-ft) is available between 1,250 and 2,000 rpm. The electric compressor provides for tremendous power when starting off. If the driver stays on the accelerator, 100 km/h (62.1 mph) is reached in roughly four seconds. Boost pressure is available immediately after each change of gears thanks to the intelligent interplay between the two turbochargers.
The most impressive aspect of both technology studies, however, is the rapid, nearly seamless development of power even at low engine speeds. The strengths of the electric biturbo lie exactly where they make the most sense in everyday driving. It eliminates the need for constant downshifting, keeping engine speeds low. Sporty drivers will really appreciate the passing power and immediate delivery of power when exiting a curve. The electric biturbo is suitable for use in many Audi model series as well as with gasoline engines, in principle. It will soon enter series production in the TDI sector.
The energy required to drive the electric compressor is largely generated by recuperation during coasting phases, so that the end effect is essentially neutral with regard to energy consumption. It is supplied with power via a separate 48-volt electrical system, complete with its own compact lithium-ion battery in the trunk and power electronics. A DC/DC converter provides the connection to the 12-volt electrical system.
The new 48-volt subsystem offers major advantages. It can supply the high-performance electrical consumers of the future – thermoelectric heating elements, electromechanical rear brakes or engine auxiliaries such as oil and water pumps – with more energy than the 12-volt electrical system. Higher voltage means lower currents, allowing for smaller cable cross-sections and thus reduced weight. Audi plans to introduce the 48-volt electrical subsystem to multiple model series shortly.
In parallel to this, the Audi engineers are also working to electrify the drivetrain. There will be a tailored solution for each customer. The hybrid platform offers numerous solutions, from the electric biturbo to the TDI with plug-in technology. The combination with the electric motor opens up new possibilities. It enables targeted shifting of the load points to the benefit of both fuel consumption and emissions behavior. In urban traffic, the electric motor provides for zero-emissions power.
Another interesting electrification option is the electric quattro drive, the e-quattro. Audi has shown this in many of its show cars. The TDI and an electric motor drive the front wheels, while a second electric motor in the rear drives the rear wheels. The battery can be installed in part in the floor tunnel.

2015 Audi R8 LMX
419 kW (570 hp), from 0 to 100 km/h (62.1 mph) in 3.4 seconds: The Audi R8 LMX (12.9 liters of fuel per 100 kilometers [18.2 US mpg]; 299 grams CO2 per kilometer [481.2 g/mile]) offers breathtaking performance and groundbreaking technology. The limited-edition car is the first production car in the world to come equipped with laser high beams. The R8 LMX can now be ordered and will debut on the streets this summer.
Audi is the leader in developing automotive lighting technology. In 2008, the Audi R8 became the first production car in the world to boast all-LED headlights; this was followed in 2012 by dynamic turn signals. Audi launched a new chapter in automotive lighting with the Matrix LED headlights, which debuted in the updated A8 in 2013. Now the brand with the four rings is igniting the next stage in the R8 LMX: the laser spot for the high beams. It increases the range substantially, which is ideal for a supercar like the R8 LMX.
The Audi engineers work very closely with their racing colleagues on the development of lighting technologies. The combination of LED and laser high beams, for example, will be used for the first time on the new Audi R18 e-tron quattro at the 24 Hours of Le Mans on June 14 and 15. The premium brand is thus continuing its tradition of using racing to test new technologies destined for production. “Audi has long dominated the most important 24-hour race. In addition to the outstanding TDI drive technology, a maximum light yield gives our pilots a major advantage, and with night racing in particular is a key factor to our success,” says Prof. Dr. Ulrich Hackenberg. “The transfer of the laser headlight to the Audi R8 LMX underscores our leading position in lighting technology. The safety benefit this provides to the customer truly represents Vorsprung durch Technik,” says AUDI AG’s Board Member for Development.
With the new laser high beams, one laser module per headlight generates a cone of light with twice the range of the all-LED headlight. Each module comprises four high-power laser diodes. With a diameter of just 300 micrometers, these generate a blue laser beam with a wavelength of 450 nanometers. A phosphor converter transforms this into roadworthy white light with a color temperature of 5,500 Kelvin – ideal conditions for the human eye that enable the driver to recognize contrast more easily and help prevent fatigue. The laser spot, which is active at speeds of 60 km/h (37.3 mph) and above, supplements the LED high beam in the R8 LMX and greatly enhances visibility and safety. An intelligent camera-based sensor system detects other road users and actively adjusts the light pattern to exclude them.
The Audi R8 (14,9 – 12,4 l/100 km [15.8 – 19.0 US mpg]; 349 – 289 g CO2 per km [561.7 – 465.1 g/mile]) is the dynamic, top-of-the-line Audi model. Its high-revving, mid-mounted engine, double wishbone suspension and ASF (Audi Space Frame) aluminum body are closely based on racing. The Audi R8 LMX is available as a coupe with a production run limited to 99 vehicles. With 419 kW (570 hp) and 540 Nm (398.3 lb-ft) of torque, its 5.2 liter, V10 engine accelerates the car from 0 to 100 km/h (62.1 mph) in just 3.4 seconds. Top speed is 320 km/h (198.8 mph), and average consumption is 12.9 liters of fuel per 100 kilometers (299 grams CO2 per kilometer) [18.2 US mpg/481.2 g/mile]. A compact, seven-speed S tronic transfers the power to the quattro permanent all-wheel drive system. 19-inch wheels are combined with carbon-fiber ceramic brake discs, which up front measure 380 millimeters (15.0 in) in diameter. Red anodized brake calipers shine behind the exclusive designer wheels. The R8 LMX is shod with 235/35 R 19 tires up front and 305/30 R 19 tires at the rear.
The new top model also sends out a clear visual signal with its Audi exclusive customized paint finish in Ara Blue, crystal effect. A large, fixed rear spoiler increases the downforce on the rear axle. Like the front spoiler lip, the flics on the sides, the engine compartment cover, the exterior mirror housings, the sideblades, the rear wing and the diffuser, it is made of carbon fiber-reinforced polymer (CFRP) with a matte finish. The Singleframe grille, the air inlet grilles up front and the outlet grille at the rear are finished in titanium gray. The sport exhaust system has high-gloss black tailpipes.
The dynamic lines carry over into the black interior, which also features blue accents. The folding bucket seats are covered in Fine Nappa leather with Sepang Blue diamond pattern. The backrest covers are finished in Ara Blue. Sepang Blue stitching provides subtle contrasts, including on the parking brake lever, the center tunnel console, the steering wheel and the instrument cowl. The black Alcantara headlining and black Fine Nappa leather door trim panels take up the Sepang Blue diamond pattern of the bucket seats.
Subtle details round out the interior. Matte carbon is used on the covers of the center tunnel console and the parking brake lever, on the inlays in the doors and the arc around the cockpit. Illuminated aluminum inlays bearing the limited-edition number are integrated into the CFRP door sill trims. Fine Nappa leather adorns the selector lever for the S tronic and the knee pads; the floor mats have black piping and Sepang Blue stitching. The Audi R8 LMX will take to the streets this summer. The base price in Germany is €210,000.

2014 Audi RS5 TDI Concept
The RS5 TDI concept technology study is powered by an enhanced-output V6 3.0 TDI biturbo boosted by an electrically driven turbocharger. This new development makes the diesel engine sportier and more efficient.
"25 years ago, Audi launched the first TDI on the market, writing the first chapter of an enduring success story," says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development. "Our latest innovation is the electric turbocharger, which further improves not just sprint times and pulling power, but also efficiency. This technology illustrates the possibilities harbored by 48-volt electrical systems, which we are currently developing for use in production vehicles."
The V6 biturbo in the Audi RS5 TDI concept produces 283 kW (385 hp); from 1,250 to 2,000 rpm it transfers 750 Nm (553.2 lb-ft) of torque to the crankshaft. The red-line is at 5,500 rpm. The supplemental electric turbocharger provides for staggering power when starting off. An electric motor replaces the turbine wheel and accelerates the compressor wheel to over 70,000 rpm in a few hundredths of a second. The exhaust turbochargers also provide as much as 2.4 bar of relative boost pressure.
This combination enables the Audi RS5 TDI concept to sprint from 0 to 100 km/h (62.1 mph) in just four seconds. The 200 km/h (124.3 mph) mark is reached in less than 16 seconds, and top speed is 280 km/h (174.0 mph). The average fuel consumption of less than 5.3 liters of diesel per 100 kilometers (less than 140 grams CO2 per kilometer) (44.4 US mpg/225.3 g/mi) documents the outstanding efficiency.
Recuperation is the primary source of the drive energy for the electric turbocharger. To transmit this energy, the RS5 TDI concept uses a separate 48-volt electrical system that is connected to the conventional 12-volt electrical system via a DC/DC converter. The energy is stored in a compact lithium-ion battery. The advantage of 48-volt electrical systems is that they enable the transmission of larger amounts of energy. This makes them an important milestone in the Audi electrification strategy.

Audi RS 4
Audi RS 4
The Audi RS 4 quattro is the top tier and highest performing version of some specific generations of the Audi A4 range of automobiles. It is a sports-focusedcompact executive car (often called sport compact in some countries), producedby Audis high-performance private subsidiary quattro GmbH, in limited numbers, for German car manufacturer AUDI AG, part of the larger Volkswagen Group. It slots distinctly above the Audi S4, as the fastest, most sports-focused model based on the A4s "B" automobile platform. The RS 4 made a comeback in 2012, in Avant form only based on the Audi A4 Avant.
The original B5 version was only produced as a five-door five-seat "Avant", Audis name for an estate car/station wagon. The second version, the B7, was released initially as a four-door five-seat saloon/sedan, with the Avant following a short while later. A two-door four-seat Cabriolet version was subsequently added. Furthermore, their unique internal combustion engines are all front-mounted, and arelongitudinally oriented. The transmission is mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle, and contains both a center and front differential.
The "RS" initials are taken from the German: RennSport—literally translated as "racing sport", and is the Audi marques highest trim level, positioned above the"S" model specification of Audis regular model line-up. Like all Audi "RS" cars, the RS 4 pioneers some of Audis latest advanced technology, and could therefore be described as a "halo vehicle". Furthermore, it is only available with Audis Torsen-based "trademark" quattro permanent four-wheel drive system.
Its main market competitors include the BMW M3, Mercedes-Benz C63 AMG, andLexus IS-F.

B5 (Typ 8D, 2000–2001)
The original B5 Audi RS 4 Avant quattro (Typ 8D) was introduced by Audi in late 1999, for main production and sale from 2000, as the successor to the Porsche / quattro GmbH joint venture-developed Audi RS2 Avant. The vehicle, like its RS2 predecessor, was available only as an Avant and was built on an existing platform, in this case theVolkswagen Group B5 platform shared with the A4 and S4. Retail price was around DM 103,584. The RS 4 was available for sale in most of Europe, parts of Asia and in some Latin American countries.
B5 bodywork and styling
Although related to the Audi B5 S4, many of the outer body panels were altered, with wider front and rear wheel arches, to allow for the wider axle trackon the RS 4. With unique front and rear bumpers and side sills, and the rearspoiler from the S4 Avant, the aerodynamic modifications achieved a drag coefficient of Cd 0.34. Although the B5 S4 came in a saloon car body style, the B5 RS 4 was only available in the Avant version.
Luggage space, measured according to the industry standard VDA method was 390 litres (13.8 cu ft) with the rear seats in the upright position, and 1,250 litres (44.1 cu ft) with the seats folded flat.
B5 powertrain
The engine was developed from the 2.7 litre 90° V6 biturbo used in the B5 S4. It displaced 2,671 cubic centimetres (163.0 cu in) and had five valves per cylinder. The parts code prefix was 078 and the identification codes were: early version, 2000 (EU2 compliant): ASJ, and later version, 2000-01 (to EU3 standard): AZR. This engine was developed and manufactured in the UK by Cosworth Technology (now known as MAHLE Powertrain). It featured enlarged intake and smaller exhaust ports on the two Cosworth cast aluminium alloy ALSi7mgcylinder heads, two parallel BorgWarner K04-series turbochargers, two larger side-mountedintercoolers (SMICs), dished piston crowns, stronger connecting rods, larger intake ducting, enlarged exhaust system, and a re-calibrated engine management system. The modifications increased the engines output from 195 kilowatts (265 PS; 261 bhp) and 400newton metres (295 lbf·ft) of torque in S4 form to 280 kilowatts (381 PS; 375 bhp) at 7,000 revolutions per minute (rpm) and 440 newton metres (325 lbf·ft) at 6,000 rpm. The engine was controlled by a Bosch Motronic ME 7.1 electronic engine control unit (ECU), using a Bosch E-Gas electronic drive by wire throttle. The engine had multipoint sequential fuel injection, a MAF, six individual single-spark coils and NGK longlife spark plugs. The engine oil was cooled by a dual oil:water cooler and an oil:air cooler.
A six-speed manual transmission (parts code prefix: 01E, identification code: FDP) (gear ratios—1st: 3.500, 2nd: 1.889, 3rd: 1.320, 4th: 1.034, 5th: 0.806, 6th: 0.684), cooled by aNACA duct in the engine undertray, and Audis Torsen-based quattro system, using the Torsen T-2 "automatic torque biasing" (ATB) center differential, with a 50:50 default bias were standard. Final drive ratio was 4.111.
Even with a kerb weight weight of 1,620 kilograms (3,571 lb), the RS 4s powerful engine gave it the performance of a sports car. 100 kilometres per hour (62.1 mph) could be reached from rest in 4.9 seconds, 160 kilometres per hour (99.4 mph) in 11.3 seconds, and 200 kilometres per hour (124.3 mph) in 17.0 seconds. Top speed was electronically limited to 262 kilometres per hour (162.8 mph).
B5 brakes, wheels and tires
Brakes were also developed jointly in house by Audis quattro GmbH, not by Porsche as with its predecessor, the RS 2. At the front they were radially vented and floating cast iron discs, 360 millimetres (14.2 in) diameter and 32 millimetres (1.26 in) thick, with double-piston floating calipers, and at the rear 312 millimetres (12.3 in) by 22 millimetres (0.87 in) discs with a single-piston floating caliper. The RS 4 needed less than 50 metres (160 ft) to come to a full stop from a speed of 110 kilometres per hour (68 mph).
The standard wheels were 18 inch alloys (8½×18" "9-spoke"), with 255/35 ZR18 high performance tyres. Optional "winter" alloy wheels were also available, at 18 inch (7½J×18"), with 225/40 R18 92V tyres.
B7 (Typ 8E, 2006–2008)
There was no RS 4 built on the Audi"B6" platform that served as the basis for the Audi A4 between 2001 and 2005. However, after a long hiatus, the second Audi RS 4 quattro (Typ 8E), was built on Audis "B7" A4 platform, by quattro GmbH in Neckarsulm, Germany. It was unveiled in February 2005 at Audis quattro Night celebration at the company headquarters in Ingolstadt, Germany.
An Imola Yellow RS 4 saloon came down a replica of a ski jump, then rotated several times on an ice rink, before coming to rest in the centre of the ice. After several minutes to allow the assembled media and guests to examine the car, the RS 4 climbed the ski jump and parked near the top. The ski jump was a homage to an Audi commercial from 1986; where an Audi climbed a ski jump in Finland to showcase its superior traction due to Audis trademark quattro drivetrain.
The RS 4 became available toEuropean customers in mid-2006. It was introduced at the 2006 North American International Auto Show in January, and arrived in June 2006 inNorth America. The production run of the B7 RS 4 was 2006 to 2008 inclusive, although only 2007 and 2008model year were sold in the United States. To date, approximately 10,000 B7 RS 4s have been built, of which around 2,500 are in the USA.
The B7 RS 4 Cabriolet, available in Europe from late 2006 to 2008, was made available as a model year 2008 vehicle in the USA.
Audi factory numbers indicate that the B7 RS 4 saloon can accelerate from 0 to 100 kilometres per hour (0 to 62.1 mph) in 4.8 seconds, and arrive at 0 to 200 kilometres per hour (0 to 124.3 mph) in 16.6 seconds.Most European magazines recorded results in line with the November 2009 comparison of "ultimate sedans", in Road & Track, which recorded a 0 to 60 time of 4.5 seconds. This is consistent with the pattern of conservatism that is usually found in Audis official performance numbers. For the Avant, 0 to 100 kilometres per hour (0 to 62.1 mph) is reached in 4.9 seconds. Top speed for all variants is "officially" electronically limited to 250 kilometres per hour (155.3 mph), though some owners have reported that the speed limiter is rather "liberal", conforming to the pattern of previous Audi "RS" cars, with genuine top speeds of 270 kilometres per hour (170 mph) being recorded.
B7 bodywork and styling
The B7 RS 4 is an almost complete departure from previous Audi "RS" cars, as it was initially available as a four-door five-seatsaloon/sedan; with a five-door five-seat Avant (estate/wagon), and two-door four-seat Cabriolet (convertible) versions arriving later. Only the Audi RS 6 had taken this similar route (saloon and Avant) before; the previous RS 4 and RS 2 were available exclusively as Avants.
Constructed from fully galvanised steel in a monocoque (unitary/unibody) design, the B7 RS 4 uses lightweight aluminium for its front wings (fenders) and bonnet (hood). The saloon version features a drag coefficient (Cd) of 0.31, from a frontal area of 2.17 m2.
Like its B5 predecessor, visually, the B7 RS 4 differs from its related B7 S4, by having even wider flared front and rear wheel arches (fenders), to allow for a wider axle track. Over the B7 A4, it also includes two larger frontal side air intakes (for the two additional side-mounted coolant radiators). The trim on the saloon and roof rails on the estate are chrome as standard but can also be found in black with the addition of the Optic Pack which includes a black front grill, all exterior trim and black roof rails on the estate version. The B7 RS 4 also includes an optional adaptive headlights to complement the standard "Xenon Plus"(Bi-Xenon arc) High Intensity Discharge (HID) headlamps, which swivel around corners in conjunction with steering wheel movements. Also standard are daytime running lights (DRLs), found within the main headlamp housings, identical to its related B7 A4 and S4, and use a conventional tungsten filament bulb. An acoustic parking system with front and rear sensors is also a standard fitment. Unique carbon fibre interior trims, along with a lap timer within the central Driver Information System (DIS), aluminium pedal caps and footrest, and RS 4 logos complete the look.
In the saloon, luggage space, measured according to the VDA block method, is 460 litres (16.2 cu ft) with the rear seats in the upright position, and 720 to 833 litres (25.4 to 29.4 cu ft) with the seats folded flat (dependent on specification). For the Avant, 442 litres (15.6 cu ft) is available with the seats upright (under the retractable load cover), and 1,354 litres (47.8 cu ft) being available with the rear seats folded flat (loaded to the roofline). Kerb weight of the saloon variant starts at 1,650 kilograms (3,638 lb) (dependent on specification).
A BOSE ten-speaker sound system, with 190 watt output and automatic dynamic noise compensation (which replaces the GALA found on earlier units), with "Concert II" radio and single CD player is standard in car entertainment (ICE) equipment. Factory fitted ICE options to complement the standard BOSE include the "Symphony II" system which features twin radio tuners, a single-slot loading six-CD changer and a cassette player all integrated into a double-DIN sized unit. Navigation option is the RNS-E "Audi Navigation System plus" DVD-ROM GPS satellite navigation, which includes a folding widescreen 6.5-inch screen, two SD-memory card readers, and MMI-like logic control.
B7 interior safety
o achieve maximum body stiffness with controlled deformation crumple zones, the B7 RS 4 features laser beam welding of major seams of the high-strength steel body shell, which helps improve overall structural rigidity, particularly in the "passenger cell", over traditional spot welding methods.
Two-stage driver and front seat passenger frontal airbags are standard,as is Audis "sideguard" head protection curtain airbag system. This latter system completely covers all of the side windows, from the front A pillar to the rear "C-" or "D pillars". The body-hugging Recaro shell-type RS race bucket seats (not available in North American markets), complete with electrically inflatable upper and lower side bolsters and adjustable lumbar support, are constructed so as not to need lower side airbags to comply with European crash safety standards. In North America, the only front seats available are the more traditional Recaro seats (identical to those in the B6 and B7 S4), which include lower side airbags; these were also available as a no-cost option in other markets. Lower side airbags are optional for the standard-fit Recaro rear seats. Front, and outer rear seatbelts include pyrotechnic belt pretensioners, whilst all belts include an excess load limit function.
B7 powertrain
The engine of the B7 RS 4 is started by an "Engine Start" button on the centre console and is based on the existing all-alloy 4.2 V8 from the B6 S4, and shares many parts, and Fuel Stratified Injection, with the 4.2 FSI V8 engine in the Q7. The engine includes new cylinder block construction, and is a highly reworked, high-revving variant (redline at 8,000 rpm; rev limit of 8,250 rpm).
The engine has increased crankcase breathing, a low-pressure fuel return system and a baffled oil sump, to prevent engine lubricant cavitation at high engine speeds and high-G cornering. It has four valves per cylinder (instead of five on the earlier variant) and two overhead camshafts on each cylinder bank (so it is quad cam) and these are driven by roller chains with variable valve timing for both inlet and exhaust camshafts, along with a cast magnesium alloy fixed tract length intake manifold with adjustable tumble flaps (to improve low engine speed combustion). On 98 RON (93 AKI) Super-Unleaded petrol it produces 309 kilowatts (420 PS; 414 bhp) at 7,800 rpm giving it a specific power output of 74.2 kW (100.9 PS; 99.5 bhp) per litre. Based on a kerb weight of 1,680 kilograms (3,704 lb), this results in a power-to-weight ratio of 184 watts per kilogram. This engine also produces 430 newton metres (317 lbf·ft) of torque at 5,500 rpm, 90 percent of the total torque being available between 2,250 and 7,600 rpm. (Using lower 95 RON (91 AKI) standard unleaded fuel slightly reduces engine output, and therefore performance, and slightly worsens fuel economy). Exhaust gas escapes through two 4-into-2-into-1 fan-branch alloy steel exhaust manifolds and four high-flow metallic sports catalytic converters,into twin oval tail pipes with integral dynamic silencer/muffler valves. The engine is controlled by two Bosch DI-Motronic MED 9.1electronic engine control units (working as master and slave, because of the high-revving nature of the engine), and uses Bosch E-Gas electronic throttle control (also known as drive by wire), comprising throttle device, accelerator-pedal module, and ECU. Theignition system uses eight individual single-spark coils, using mapped direct ignition, with Bosch single iridium electrode or NGKtriple-electrode long-life spark plugs. Ignition timing is monitored with the aid of four knock sensors. The engine complies with the Euro4European emission standards. The saloon version produces 322-329 grams of CO2 per kilometre (g/km), and the Avant starts from 324 g/km.
A six-speed Getrag manual gearbox (parts code: 0A3, identification codes: HLD, JHM) is the only transmission available. The gear ratios are 1st: 3.667, 2nd: 2.211, 3rd: 1.520, 4th: 1.133, 5th: 0.919, 6th: 0.778.
The Audi B7 RS 4 was the only "RS" Audi powered by a naturally aspirated engine until the Audi RS5 was presented at the 2010 Geneva Motor Show. The RS5 also uses a 4.2 litre high revving V8, which puts out 450 horsepower, however the RS5 engine is based on the 5.2 liter V10 in the R8, and is not related to the RS4 engine.. The RS5 also dropped the Getrag 6-speed manual in favour of a 7-speed "S tronic" dual clutch semi-automatic.
