Second Generation R8

Second Generation R8 to Debut in Geneva

Audi presents the new R8: The sporty spearhead just got even sharper.



  • The second generation of the high-performance sports car makes its debut in Geneva
  • 5.2 FSI engine with up to 610PS, 0 to 62.1 mph in 3.2 seconds
  • New multimaterial Audi Space Frame with high proportions of aluminium and CFRP



The two V10 engines
The new generation of the Audi R8 utilizes the latest development of the ten-cylinder engine. With its spontaneous throttle response, quick revving up to 6,500 rpm and inimitable roaring sound, the naturally aspirated 5.2 FSI engine is enough to give you goose bumps. In the new R8, the freely aspirated V10 engine offers even more power and torque than before. Controllable flaps in the exhaust pipe and an optional sport exhaust system make the car sound even more characteristic.

The ten-cylinder engine is available in two versions. In the R8 V10, it develops a power of 540PS  from its 5,204 cc displacement and a torque of 540 Nm at an engine speed of 6,500 rpm. The sprint from 0 to 62.1 mph takes just 3.5 seconds, and it can reach a top speed of 200.7 mph. The R8 V10 plus is even more powerful and is the fastest series-production Audi of all time. 610PS and its maximum torque of 560 Nm is available at 6,500 rpm. The performance figures are equally impressive: 0 to 62.1 mph in 3.2 seconds, 0 to 124.3 mph in 9.9 seconds, and a top speed 205.1 mph.

Fast as lightning and highly variable: the power transmission
In both engine versions, power is transmitted to a rapid-shifting seven-speed S tronic transmission installed behind the engine. The S tronic has three automatic modes and can also be controlled manually. Shift commands are transmitted electronically (shift-by-wire). The launch control system manages full-throttle acceleration from a standing start.

Another function of the S tronic comes into play when the driver’s foot is removed from the accelerator pedal at speeds above 34.2 mph. In such cases, both clutches open and the car goes into coasting mode. This function saves a considerable amount of fuel, especially in everyday use by the customer.

The quattro permanent all-wheel drive system gives the new R8 a decisive plus in terms of stability and traction when compared with two-wheel-drive competitors. On the front axle, an electrohydraulic multi-plate clutch replaces the Visco clutch of the predecessor model. The newly developed quattro drive system enables completely unrestricted and fully variable distribution of the drive torque to the front and rear axles depending on the driving situation and weather. In normal operation, up to 100 percent is transmitted to the rear wheels and, if required, the clutch continuously diverts up to 100 percent of this torque to the front wheels. Thanks to the mechanical differential lock on the rear axle, the driver experiences maximum traction without any slip.

Audi drive select: the chassis
In the chassis of the new Audi R8, double wishbones made from aluminum guide all four wheels. The R8 V10 plus has a particularly sporty setup – for both engine variants, variable adaptively controlled Audi magnetic ride shock absorbers are available as an option. The newly developed electromechanical power steering system provides close contact to the road surface and makes a further contribution to reducing CO2 emissions. As an option, Audi offers dynamic steering, whereby the steering ratio varies in accordance with the road speed and the settings in the Audi drive select dynamic handling system.

As standard, the new Audi R8 V10 has 19-inch wheels with size 245/35 tires at the front and 295/35 at the rear. Upon request, Audi is also offering 20-inch wheels for the first time in the R8. With this option, the tires are size 245/30 at the front and 305/30 at the rear. The steel brake disks have a weight-saving wave design and the calipers can be painted red upon request. In the R8 V10 plus, high-tech disks made from carbon fibre ceramic are responsible for deceleration of the 20-inch wheels (optional for the V10).

In the Audi drive select dynamic handling system, the driver has the choice of four modes (comfort, auto, dynamic and individual) to control the way in which important technical components operate. As standard, the system takes into account the engine characteristics, steering, S tronic transmission and quattro drive system as well as optional extras such as Audi magnetic ride, the exhaust flaps and dynamic steering. On top of that, there is also the new performance mode (available as an option for the V10 and standard for the V10 plus). The driver activates it by pressing a separate button on the steering wheel. He or she can select between the programs dry, wet and snow using a rotary wheel. These programs support dynamic handling on dry, wet and snow-covered surfaces. In performance mode, Audi drive select also makes use of the ESC stabilization control function.



New Audi Space Frame with high proportions of aluminum and CFRP
The R8 V10 plus has a dry weight of 1,454 kilograms. The key factor behind the consistent lightweight design is the body shell with multimaterial Audi Space Frame (ASF): It weighs only 200 kilograms. The resulting unladen weight of 1,555 kilograms leads to a superior power-to-weight ratio of 2.55 kg/hp.

The ASF body shell features a completely new multimaterial lightweight construction concept. Components made from carbon fibre reinforced plastics (CFRP) form the B‑pillars, the central tunnel and the rear wall. The front section of the vehicle, the roof arch and the rear section form a framework made from cast aluminium nodes and aluminium profiles which, in some cases, employ new alloys. As always with the ASF, each component is precisely designed for its location and purpose. Accordingly, the engineers have now integrated some components into the body shell due to their function. Leaving aside its components, the body shell is now around 15 percent lighter than its predecessor. At the same time, torsional rigidity is roughly 40 percent better. Particularly with regard to rigidity, the body of the new Audi R8 is a benchmark. The resulting lightweight construction is unparalleled among the competition.

The multimaterial Audi Space Frame in the new Audi R8 is extremely light and rigid, whilst also being acoustically comfortable and offering a high level of safety. The outer skin is made entirely of aluminium, but as an optional extra (or as standard for the V10 plus), Audi also offers attachment parts made from clear-coated carbon fibre, for example the front splitter, the diffuser or the side blades. A long, rising diffuser in the underbody produces downforce on the rear axle at higher speeds.



Just like in a race car: the interior and the controls
Behind the steering wheel of the new Audi R8, the driver feels like a race car driver. All functions are driver-oriented and allow easy operation even when the critical limits are reached – and all without the driver having to take his or her hands off the steering wheel. The newly designed sport seats with integrated headrest provide excellent lateral support. Even more radical seating for a sports car comes in the form of the newly developed R8 bucket seats. These make a clear statement confirming the relationship between lightweight construction and comfort (optional in the V10 and standard in the V10 plus).

The start-stop button and the Audi drive select button are located on several satellites on the new multifunction plus steering wheel. The Performance steering wheel in the Audi R8 V10 plus features two more satellites. One button is for performance mode together with a rotary wheel for selecting the dry, wet and snow programs as well as a button for controlling the sports exhaust system.

The Audi virtual cockpit is set in a free-standing housing and presents all the information on its 12.3-inch display with elaborately computed, fascinating graphics. The driver can toggle between different display modes and also adjust the digital instrument cluster to his needs in individual mode. In performance mode, the driver is presented with information on the driving programs, acceleration, deceleration and lateral forces as well as power and torque. The Audi virtual cockpit also displays a shift light which informs the driver that the engine speed limit has been reached. The driver operates the Audi virtual cockpit using the multifunction plus steering wheel. The driver’s hands remain on the steering wheel and he or she can concentrate on the road. Alternatively, operation can take place via the touch wheel or the buttons in the centre console.

In the design of the interior too, the taut geometric lines emphasize the aesthetic lightweight construction of the brand. Its characteristic element is the monoposto, a large arc in the area around the driver’s seat. The MMI monitor of the previous model is no longer available. Instead, the three central control elements of the air conditioning system have taken its place. The three-dimensional design of the air outlet vents bring to mind the air inlets of a race car. The dashboard appears to float weightlessly. The wide console of the central tunnel accommodates the standard MMI terminal as well as the newly designed flat selector lever of the S tronic transmission.

When it comes to upholstery, customers can choose between Alcantara/pearl Nappa leather and fine Nappa leather. Also available are trim elements in clear coated carbon fibre, two leather packages and a new diamond stitching pattern.

Customisation
There are numerous customization possibilities for customers of the new Audi R8 – for both the exterior and the interior. The colours for the body have been newly mixed and can be freely combined with the colours of the side blades – a blade made from glossy carbon is a particular highlight of the range. Ten standard exterior colours are available, for the R8 V10 plus there is an additional matt paint finish available, Camouflage Green.  

Among the five equipment colours available for the interior, two colour ranges can be found, whereby the interior is always characterized by a sporty feel. Additionally, there are numerous options to further customize both the interior and the exterior, for example with headlining in Alcantara with dynamic diamond stitching pattern. The Audi exclusive program makes it possible for you to turn the new R8 into a one-of-a-kind model.
