Audi is presenting a revolution in the top class at the Detroit Auto Show 2008 - the first 12-cylinder diesel engine in a high-performance roadgoing sports car. The V12 TDI with a displacement of six liters powers a concept car based on the Audi R8. This unit generates a huge 500 hp and 1,000 Newtonmeters (737.56 lb-ft) of torque. Audi is writing a new chapter in diesel technology with this power unit. Equipped with the expertise that Audi has built up through its motor sport activities, the R8 V12 TDI in matt "Grace Silver" embodies superb road handling, pioneering technology and fascinating design.
The V12 TDI is closely related to the engine in the Audi R10, the two-time Le Mans winner - so it catapults the Audi R8 into supercar terrain concerning performance too. It sprints from zero to 100 km/h (62.14 mph) in just 4.2 seconds and its top speed is well over 300 km/h (186.41 mph). The peak torque, reached at only 1,750 rpm, paves the way for effortless acceleration that is unrivaled even at this level.
The new V12 TDI belongs to Audi's family of V engines but has the ideal included angle for this engine type of 60 degrees between cylinder banks. Its highlights include the new chain drive layout that includes the two newly developed high-pressure pumps for the common rail injection system. Its sound is as thrilling as you'd expect in a sports car of this caliber. For all the subtle smoothness that typifies this design principle, the twelve-cylinder unit is full-bodied and equipped with energetic overtones that make no secret of its performance potential.
The Genes of the Winner
Thanks to their high performance and pulling power, all Audi TDI engines are ultra-dynamic sources of power. The brand has often enough demonstrated its sporty character in its production cars, especially the six- and eight-cylinder 3.0 TDI and 4.2 TDI. Audi has also been writing a new chapter in its success story on the racetrack since 2006. The diesel engine in the R10 sports prototype won its very first endurance race at Sebring, Florida, when it was pitted against an entire field of gasoline-engined challengers. But its most crucial victories were surely in 2006 and 2007 in the 24 Hours of Le Mans, when it simply outclassed the international elite.
The V12 TDI race engine in the R10 produces over 650 hp from a displacement of 5.5 liters, giving it the potential for a top speed as high as 330 km/h (205.05 mph) depending on the gear ratios. Its power and sturdiness immediately impressed both fans and experts, who were impressed by its restrained noise level. Unusual for a race engine, this powerful Audi diesel makes barely more than a whisper.
Long traditions of motor racing and production technology complement each other at Audi. The FSI engine of the R10's predecessor, the R8, captured five wins at Le Mans with a direct gasoline injection system. Audi is also looking to maximize the advantage by using the race-tested FSI principle in its production models. The latest examples of this are the V8 with high-revving concept in the RS 4 and the production version of the Audi R8.
The Drivetrain
The roadgoing version of the new V12 TDI is built at the Györ plant, in Hungary. And the R8 V12 TDI still has a massive 500 hp on tap. In developing the six-liter engine, it was a clear priority to integrate it into the current family of Audi V engines, of which many thousands of versions with 6, 8 and 10 cylinders have already been built - both gasoline and TDI.
Audi's engineers were in an ideal position to use their experience building the racing engine to develop the road version. Like the other power units in this range, the distance between cylinder bore axes on the V12 TDI is 90 mm (3.54 in.). Yet its included angle is 60 degrees, not 90 degrees. This means no free inertial forces or mass moments of inertia can occur with the V12. The results are refined in every respect.
The 83.0 mm (3.27 in.) bore and 91.4 mm (3.60 in.) stroke produce a total displacement of 5,934 cc - just like the 3.0 TDI. At only 684 mm (26.93 in.) long, this large diesel engine is very compact and just 166 mm (6.54 in.) longer than the V8 TDI. This compact length is key to accommodating the V12 in the midengined Audi R8.
The V12 TDI crankcase is made from gray cast iron with vermicular graphite - a high-tech material referred to as GJV-450 that is already used on the V6 and V8 TDI engines. GJV-450, made by a patented casting process, is about 40 percent more rigid and 100 percent more fatigue-resistant than gray cast iron. This enabled the developers to make its walls thinner, cutting its weight by around 15 percent compared with conventional gray cast iron.
The two cylinder heads are each made from three main elements. These are a base section made from a high-strength aluminum alloy incorporating the intake and exhaust ports, an oil-bearing upper section, and a reinforcing ladder frame supporting the two camshafts.
The valves are actuated by low-friction roller cam followers; the compression ratio is 16.0:1. Map-controlled swirl variation of the combustion air has been adopted from the V6 and V8 TDI engines. This produces permanently optimized swirl concerning both emissions and high performance.
Ultramodern Injection Technology
As is the case in the Audi V engines, the no-maintenance chain drive is mounted at the back of the engine, where it occupies little space. Its layout has changed on the new V12 TDI. The camshafts' sprocket engages in an intermediate gear via which two Simplex chains drive the camshafts. Two more chains drive the oil pump and the two high-pressure pumps actuate the common rail injection system.
The two new dual-piston high-pressure pumps form part of the common rail injection system supplied by specialty manufacturer Bosch. The two pumps build up a pressure of up to 2,000 bar in the rails. The piezo injectors with eight-hole nozzles have also been fundamentally revised.
The high pressure distributes the mixture optimally throughout the combustion chamber. The result is that the ignition process is faster, more homogeneous and more acoustically refined. The more efficient combustion process also increases power output, cuts consumption and reduces pollutant emissions.
The current generation of so-called inline injectors makes effective use of the piezo effect: piezo crystals expand in a fraction of a millisecond when an electrical voltage is applied. The number of injection processes per operating cycle can be varied across a wide range thanks to piezo technology - reaching as many as five fuel injection operations in the case of the V12 TDI.
As well as the main injection, pilot and post injections are possible. Pilot injections tone down the acoustic harshness of the combustion process. Retarded post injections are designed specifically to increase the temperature of the exhaust gas, promoting regeneration of the two standard particulate filters.
The two turbochargers are located on the outside of the engine's V, each of them supplying one bank of cylinders. Thanks to their variable turbine geometry, the full flow of exhaust gas always passes through the turbine, so the chargers respond slickly - even at low engine speeds - and operate very efficiently.
The two turbochargers, which generate up to 2.6 bar of boost pressure, play a crucial role in producing the huge torque of 1,000 Nm (737.56 lb-ft) that the V12 TDI maintains from 1,750 rpm to 3,000 rpm. In developing 368 kW (500 hp), the diesel achieves a specific output of 62.0 kW (84.3 hp) per liter displacement.
Two large intercoolers reduce the temperature of the compressed air. The V12 has a twin-pipe exhaust system with two particulate filters. The intake system is similar in structure with one air cleaner per cylinder bank, with an airflow meter behind it. Two control units, sharing the workload in a master/slave principle, manage events in the engine.
The Audi R8 V12 TDI concept already fulfills the Euro 6 emissions standard that is likely to take effect in 2014 and calls for sharply reduced nitrogen oxides. By also designing in ultra-precise fuel metering by the common rail system, Audi's engineers have made full use of current clean diesel technology.
The heart of the system is a special catalytic converter downstream of the oxidizing catalyst and the particulate filter. The second component in the system is an additional tank containing an aqueous urea solution. Small quantities of the solution, known as "AdBlue," are injected into the exhaust system. The hot exhaust gases break the solution down to form ammonia that splits the nitric oxides into nitrogen and water. The system remains effective for the entire service life of the vehicle.
The dynamic character of a sports car depends not just on its performance and torque; the transmission ratios have to be right too. In keeping with the character of a high-performance sports car with unbeatable torque potential, the transmission in the R8 V12 TDI has six manually operated gears.
The manual transmission is very compact in design. Together with the smalldiameter double-plate clutch, this means it can be installed low down. The manual transmission has very short shift travel and utterly precise guiding of the shifter into the open gear lever gate. It is made from polished aluminum, has an agreeable feel and exquisite sports car looks.
Such a high-performance Audi also has quattro permanent all-wheel drive. In the case of this mid-engine sports car, power is distributed variably between the front and rear wheels from a starting ratio of 40:60 to optimize the handling.
The Design
The R8 V12 TDI concept with matt "Grace Silver" bodywork looks even wider and more resolute than the core model. It shows its potential through its muscular proportions, accentuated wheel arches and even larger air apertures. The rhombuspattern cover on the air inlets and outlets is the hallmark of Audi's sporty top models and a familiar feature of the current RS generation.
Typical of the side view of the R8 is the sideblade. Much wider in the bottom third, it visually accentuates the engine's position as well as acting as an enlarged air deflector.
The continuous aluminum spoiler lip that connects the front and rear diffusers with side air baffles below the enlarged sills also pays tribute to this version's highly developed dynamic talents.
And yet the R8 is unmistakable for its powerful, elegant basic proportions. The selective but always precise use of lines is another typical Audi characteristic, as is the curved arc of the roof. One new aspect is the glass roof of the passenger compartment with two large transparent sections. These, together with the glazed engine compartment behind, create a radically new formal element. The unmistakable NACA duct in the middle of the roof is a functional detail that is normally reserved for racing cars. Its ingenious shape accelerates the air drawn in here for the two cylinder banks of the V12 TDI engine.
The V12 TDI is displayed as the beating heart of this sports car, like a work of art inside a large showcase. Its look, underscored by the air deflectors located beneath the restyled rear glass lid, differs clearly from its production counterpart. The engine can even be seen after dark, when white light-emitting diodes illuminate the engine compartment - as on the production R8 version. This "showroom" can additionally be fully lined in genuine carbon fiber, for a particularly exclusive The continuous line running from the front apron across the wheel arches and flanks to the tail end, then back down the other side, is one of the latest design hallmarks of the Audi brand. This "loop" naturally encompasses the air apertures, the headlights and the taillights.
Unmistakable Face by Day and Night
The passion expressed through the elaborate design of the lights is another typical Audi trait. Nor is anyone likely to overlook this Audi sports car from behind: the LED taillights have a three-dimensional look that can't be missed.
But the absolute highlight is the all-LED headlights of the study vehicle. With their lenses and reflectors, not only do these innovative light sources have a ground-breaking appearance, they also have an enormous functional advantage: LED light, with its color temperature of 6,000 Kelvin, resembles daylight much more closely than xenon or even halogen light. Better light means the driver will have much less fatigue when driving at night.
Audi R8 EDO
The fastest Audi ever already accelerates from 0 to 100 km/h (62 mph) in 4.7 seconds in factory trim. The edo R8 needs just 4.5 seconds and achieves a top speed of over 310 km/h (192 mph).
edo competition offers this new full stainless steel high-flow exhaust system in two different sounds levels. The result is a power increase of 16 kW (22 hp) and a 20 Nm (15 ft-lb) increase in torque. The trimetal-coated high-flow catalytic converters, which were designed specifically for the R8, ensure full OBD2 compliance and feature impressive performance.
At edo competition form and function are strongly connected. The R8's perfect balance and improved downforce, thanks to the body upgrades, become especially apparent when the car is accelerating. The edo R8 owes its aerodynamic advantages to a newly developed front lip spoiler and 8 rear bumper inserts. The new rear diffuser, also providing additional downforce, has an even greater effect. As usual at edo competition, the aerodynamic components are available in super light-weight carbon fiber.
The sporting concept is rounded off by edo competition's latest wheel design. No matter whether in 19 or 20 in., these performance wheels perfect the R8's impressive appearance and feature high-strength forged centers with polished stainless steel outer rims and high-strength aluminium inner rims. All sport wheels can be custom painted.
Audi R8 ABT
Design milestones of sports car construction do not only come from Sant' Agata Bolognese or Maranello but also from Kempten. Because there, in the picturesque Allgäu region, Abt Sportsline, the greatest tuner for vehicles from the Volkswagen group, is based. With the new Abt R8, the term "improvement" is set one level higher as this car combines technical competence and brilliant design from Abt and results in an automobile masterwork. Not more and not less. The Abt R8 is a fantastic super sports car, playing in the same league as Lamborghini Gallardo or Ferrari F430.
No doubt, even the basis model of the R8 is something special - and therefore a real challenge, emphasizes Hans-Jürgen Abt. "The fluently dynamic form of the car is unique, it looks like having a lot of power, even when standing still," admits the managing director and therewith he raises the bar for his engineers and designers. As it is usual for Abt, the result is quite respectable and can be driven with fascination. The light and sporty high-tech material Carbon well visibly shapes the rear skirt, the side blades and the side skirts. The exciting body kit of the two-seater was developed by the motor sports professionals from Kempten who also optimized the car in reducing weight and in distributing mass evenly. That optical features do not obviate technical sophistications but, on the contrary, lead to perfection clearly show the contours of the Abt R8. Front skirt, side skirts, and rear skirt form a unit in which the rear wing, the side blades and also the exhaust system are harmonically integrated. A special highlight is the front skirt partially made of sight carbon. It is a component of the equipment version "Extravagant". The customer is able to provide his Abt R8 with attachment parts, at his own option with elements of sight carbon. A two tone structure is also possible by request. Another alternative ist the equipment version “Exclusive”, which offers the customer the possibility to beautify his R8 with an Abt body kit made of high-quality GRP (glass fibre reinforced plastic). Also the new BR wheel from Abt with its bi-colour paint perfectly fits the car. The front axis presents it in the size 9x20 inch, the rear axis in 11x20 inch. Thus the R8 appears much more dynamical. With Abt suspension springs and car lowering the team from Kempten improves the road holding even more as Christian Abt and his specialists exactly adjusted the suspension. With the Abt sports brake system (380 millimeters diameter), the fast super sports car from the Allgäu sets standards also in matters of delay.
The new Abt R8 is a car which makes hearts beat faster. It perfectly brings the magic of speed onto the road even when standing still.
Audi Q7 V12 TDI Coastline Concept
Audi is presenting a very special concept car at the Geneva Motor Show: The Audi Q7 coastline combines the breathtaking power of a twelve-cylinder TDI with the elegant style of an exclusive yacht. A large part of the high-performance SUV’s exterior and interior is bathed in a trendy white. Under the hood resides the world’s strongest diesel engine in a series-production vehicle – the six-liter V12 capable of delivering 368 kW (500 hp) of power.
The Audi Q7 coastline comes in Inuit, a special white that creates a pearl effect reminiscent of the glistening luminance of the polar region. Audi, the leading brand in automotive design, initiated a popular trend with this color years ago – studies such as the white Shooting Brake Concept displayed at the Geneva Motor Show 2006 have become style-setters.
In contrast to the production version of the Q7 V12 TDI, the casing for the exterior mirrors on the Audi Q7 coastline is white as well; the single-frame radiator grill and the side air intake slots come in dark High Gloss Steel. The Audi Q7 coastline has the same body modifications as the Audi Q7 V12 TDI, with widened wheel arches and striking front and back bumpers that immediately catch the eye.
The equally stylish and trendy interior is dominated by alabaster white, a color popular on luxury yachts. Also in luminous white are the carpet, embroidered floor mats made of fine wool, pillar trim, roof lining, seat upholstery made of plush velvet and Valcona leather, seatbelts, steering wheel, the front of the cockpit and the door trim. The majority of the switches and controls as well as the instrument panel with cowl are likewise in this trendy color from Audi.
In the interior, additional accents are set by aluminum elements on components such as the air inlet nozzles and door handles. Further trendy touches include nut brown piping on the seats as well as fine brown piping on the instrument panel and the door. Parts of the armrest, the gearshift lever knob and the inner door sill trims are made of American walnut veneer in which thin strips made of dark smoked oak wood have been embedded as a further maritime reference. The same combination can also be found on the floor of the luggage compartment, which contains two integrated folding boxes. The wood is waxed, not varnished. As a result, the pores in the wood remain open, giving it a uniquely charming feel and silky glow.
Concentrated power and high efficiency: 368 kW (500 hp) and 1,000 Nm (757.56 lb-ft)
Under the hood of the Audi Q7 coastline concept car resides a concentrated powerhouse: The V12 TDI is writing a whole new chapter in the annals of diesel technology. Drawing on 5,934 cm3 of displacement, the six-liter engine delivers 368 kW (500 hp) of power and an impressive 1,000 Nm (757.56 lb-ft) of torque between 1,750 and 3,000 rpm. As a result, the vehicle performs like a world-class sportscar – sprinting from zero to 100 km/h (62.14 mph) in just 5.5 seconds with an electronically limited top speed of 250 km/h (155.34 mph). On average, the world’s only 12-cylinder diesel engine in a passenger car uses just 11.9 liters of fuel per 100 km (19.77 mpg) – a much better figure than comparable gasoline engines from competitors.
The unique diesel power of the Audi Q7 with V12 TDI engine is not the only factor to render it the ultimate high-performance SUV. Equally sporty in nature are the vehicle’s six-speed tiptronic and quattro drive as well as running gear with adaptive air suspension. Behind the large wheels are ceramic brake disks. A DVD navigation system, a Bang & Olufsen Advanced Sound System and leather seats with electric heating and adjustment switches are symptomatic of the luxurious standards in the Audi Q7 coastline.
Audi Q7 JE
True to the motto of "everything or nothing", the car styling specialist from Leingarten,Germany, customizes the Q7 to create an impressive car. In addition to the muscular wide body kit, which makes this Audi look even more powerful, JE DESIGN is also offering a performance enhancement, new rims and an electronically lowered suspension.
Brute supercharger power!
2.3 tons of unladen weight are not that easy to gloss over. With that much weight, every scrap of power and every Newton meter of torque counts. The basic specifications of the 4.2-litre Audi Q7 do indeed make quite an impressive read. After all, 257 kW / 350 bhp, 440 Nm at 3500 rpm, a top speed of 151 mph and 7.4 seconds for the sprint from 0 - 62 mph are not exactly chicken feed. But JE DESIGN turns the Q7 into real high-flyer, with no less than 500 supercharged horses (368 kW) rearing and bucking under the hood. 600 Nm of torque, available at 3,850 rpm, propel this heavyweight from a standstill to 62 mph in just 5.6 seconds. And it does not stop till it reaches an impressive 169 mph. The supercharger conversion includes a water-cooled intercooler, an exhaust system from the manifold, special forged pistons and modified engine management. JE DESIGN also takes care to ensure that the Q7 still complies with the emissions regulations. The conversion also includes TÜV certification.
Muscular styling kit
JE DESIGN lends the Audi Q7 greater width and an awesome-looking stance. The styling kit includes headlamp lens caps, which lend the car a more aggressive look. Fitting the impressive front spoiler helps to reduce lift. It can also lend the Q7 greater prestige when overtaking. Also, it is possible to equip this Audi SUV with a set of JE DESIGN twin headlamps, which look far better than the original headlamp design. JE DESIGN enhances the appearance of the rear end by equipping the Q7 with a new tailgate skirt attachment, which incorporates diamond-shaped openings on the right and left. In each of these openings belongs a JE DESIGN dual tailpipe from made permanently shiny, corrosion-resistant stainless steel.
The upper part of the rear end is also spectacular, which JE DESIGN adorns with a wing spoiler tail fin including a C-pillar trim. A feature that is sure to get heads turning. The same also applies to the JE DESIGN fender flare kit "WIDE BODY", for which matching door panels are also available. In front of the rear fenders, air inlets lend the car a sportier look, without appearing "plump". JE DESIGN is offering the muscular look as a complete body-styling kit which is cheaper than buying all single parts piece by piece.
Which rim?
Also when it comes to rims, JE DESIGN does not miss a thing. First off, the tuning specialist offers its complete set of wheels JE DESIGN "361" in the dimension 10 x 22 ET 20 (front) and ET 10 (rear) fitted with size 295 / 30 R 22 Y tires. The rims are also sold separately and are specially adapted to the wide body kit. Secondly, JE DESIGN offers a complete set of wheels AZEV "R-Wheel" in the dimension 10 x 22 ET 50 with size 295 / 30 R 22 Y tires. These rims are also sold separately . For rims with a wheel offset of 50, JE DESIGN recommends using its aluminum track extensions, which add an extra 60 mm width on the front axle and as much as 80 mm on the rear axle.
The fine figure of the JE DESIGN Q7 is rounded off by an electronically lowered suspension, which the car customizer from Leingarten offers for cars with air suspension and which finally helps the JE DESIGN Q7 to morph into a true racing SUV.
Audi Q7 Hofele
Special attention of the new Hofele concept for the Audi Q7 draw the new bumpers, made of the high-quality material RIM. The front bumper is highlighted by the big air intakes, the Single-Frame grill from the S8, A8 or W12 and four Hella lights. These lights are LED day driving light + fog and cornering light. The use of the A8 grills makes the front rounder than on the original Q7.
An eye-catcher are the stainless steel tailpipes which are integrated into the rear apron. A flat roof spoiler sits on the edge of the tailgate. Door attachments with an air intake stretch the sides of the luxury SUV.
The price for the complete kit starts at 3.800,- Euro.
Wheel arch extensions on all four fenders cover the mighty wheels. As wheel and tire combination the new „Reverso 22“ designer wheel in the size 10Jx22“ with tires 295/30 R 22 are mounted. The four wheels with Pirelli tires cost 4.750,- Euro. The car is lowered 40mm and also wider thanks to wheel spacers. For cars with an adaptive air suspension an electronic lowering module is available.
With an electronic tuning kit, the output of the 3,0 TDI can be increased from 233 HP and 500 Nm to more than 280 HP with 580 Nm. Price for the kit: 1.150,- Euro.
Also available for the Q7: an exclusive interior concept with carbon, exotic woods and leather for instrument panel, steering wheel and door trims.
All parts are being mounted to the original points of fixation. This is easy going and requires no modifications to the car at all.
All parts are TÜV approved and are on sale now.
Audi-Tuner Hofele-Design is the specialist for all Audis, especially for the luxury cars A8, Q7 and R8.
Audi AS5 ATB
Unobtrusive design and powerful appearance - this is what the Abt AS5 stands for. With a discerning eye on the detail Abt enhances the elegant Audi Coupé with its breathtaking, pleasing contours and the stretched flanks. The team from Kempten has managed to upgrade the unique vehicle without changing its character. With the two coloured paint and the Abt body kit, the AS5 appears like a mannequin in an extravagant designer tailor-made suit.The front skirt, in which a grid element accents the front fog lights and the single-frame grill, the strikingly curved lateral parts, the fender insets and the gill-shaped air inlets form a shapely unit. The Coupé is a unique and beautiful car, no matter from which perspective. The rear skirt inset with the diffuser excellently harmonizes with the 4-pipe rear muffler, together with the perfectly designed rear spoiler it accentuates the rear of the vehicle. As ideal complement, Abt recommends the new BR wheel in 20 inch. With its superposed spokes, the wheel seems to rapidly move forward although it is standing still.
The Abt AS5 is not only optically a real sports car. In Essen it is presented with the powerful 3.0 TDI engine which, thanks to Abt Power S, now brings 300 HP (221 KW) onto the road instead of the serial 240 HP (176 KW). The torque of 600 Nm is getting free at already 2400 rpm and provide for shear force in all situations. Also impressive is the acceleration of the self-igniting engine. Exactly 5.3 seconds needs the car from standing still to 100 km/h, the top speed is 264 km/h - values which suit to a sporty Coupé like the Abt AS5. In order that the impressive power remains controllable, Christian Abt, motor sport professional, excellently adjusted the Abt thread sports suspension in detail. And the Abt brake system with discs 380 millimeters diameter powerfully grips.Abt multifunctional sports steering wheel, soft nappa leather grip and carbon look leather adorn the driver's workplace. Abt aluminium pedals and gear shift knob complete the sporty accent in the interior. A successful masterpiece can be seen at the ESSEN MOTOR SHOW, the Abt AS5. The only downside is: It wants to be driven and this, unfortunately, is impossible in the exhibition hall.
