Audi V10 quattro performance: Audi R (oooaaaaam) 8



Visually, the R8 that is lifted with a 4.43 meter surface is now a little more jagged and tense. One-frame grille with honeycomb insert is now wider and flat, chrome frame is history. There are also new air intakes. LED headlights with 37 LEDs each standard, with optional laser lights and animated turn signals. In addition there are new frames, new air grilles installed in the honeycomb for engine compartments. Diffuser on the back is stretched further, the exhaust system has elliptical tailpipes. The quattro rear performance of the R8 Coupe V10 is decorated with large fixed wings made of carbon fiber reinforced plastics (CFRP).

Arch wheels are equipped with 19-inch wheels as standard, and 20-inch wheels are also available on request. At the rim, Audi now also offers tires developed specifically for the R8, which shows a much more significant grip, at least on the racetrack – bends make it a little faster and more precise. Before the R8 starts to falter, you have to do many things. Inside, however, it hasn't really changed what and also the wheelbase remains equal to 2.65 meters.

But that is primarily a technical change that raises the R8 to the current level. Two central V10 suckers with a 5.2 liter displacement, which had given the athlete a reprint, even got a small Leistungsnachschlag. The base unit rotates up to 8,700 rpm and now gives 419 kW / 570 hp (30 hp increase) at 8,000 rpm and with 560 Nm at 6,200 rpm and 20 Nm more torque. In the quattro performance of the Audi R8 V10, which used to be called the R8 V10 plus, the display is a bit simpler: its performance increases 10 hp to 456 kW / 620 hp and maximum torque of 580 instead of 560 Nm.

It also provides a small plus in driving: Base V10 speeds up 1.6-ton two passengers now as coupes at 3.4 and Spyder in 3.5 seconds from zero to 100. The top speed is now at 324 or 322 km / hour. So far, 320 km / h has ended. Performance V10 now manages the Tempo 100 sprint in 3.1 (coupe) each in 3.2 seconds (Spyder). No wonder: every horsepower must move only 2.57 kilograms. The highest speed is now 331 km / h (Spyder: 329 km / h). To create Euro 6d-Temp emission standards, both units were given a particulate filter. For more economical consumption, cylinder deactivation and sailing operations ensure a relaxed driving style. At low to moderate loads, the cylinder of one bank does not move in the four upper teeth, injection and ignition is deactivated there. Transition between partial and full cylinder operation is not considered when driving.

Both machines respond spontaneously and precisely to the command coming from the gas pedal – the suction stops. The pressure on the starter button on the steering ensures the right sound: heavy metal, not the space quartet. The engine roars happily, with each round creating a new composition of ten cylinders. At a neat speed and speed the flap opens in the exhaust system and gives more noise.

Performance improvements are achieved mainly by optimized valve trains: 40 valves, their springs and roller rocker arms now made of titanium. The engine has dry sump lubrication as in racing. The seven-speed S trick mounted behind the control engine is almost uninterrupted and perfect. For those who want something extra sporty: At the touch of a button, Launch Control ensures a fast start.

Audi has also optimized the R8 suspension and steering with technology from motorsport. For example, double aluminum wishbones lead all four wheels. The Audi engineers are very proud of the newly developed stabilizer on the front axle, which consists of a layer of carbon fiber reinforced plastic (CFRP) wound into the tube. The legs are made of red anodized aluminum. Weight savings on the front axle: around two kilograms. The rack-and-pinion power electromechanical steering has been completely reset. For example, the steering dynamically changes the ratio between 10.5: 1 and 15.8: 1, depending on the driving speed. You can find out that in city traffic it is as clear as on a highway or racetrack. At low speeds, the R8 can maneuver comfortably, on the runway it leads right and directly around the driven corners quickly – without having to crank a lot on the steering wheel. In performance mode is from 140 km / h, the constant ratio is 14: 1 at.

The updated Audi R8 will go on sale in early 2019. Audi doesn't talk much about prices – currently the R8 quattro costs as a coupe of 166,000 euros, as a "plus" version of 196,000 euros. Spyder is around 13,000 euros more expensive. In the same context, it should also be after a facelift – plus ordinary "inflation compensation".
