Audi R8 V10 - Born of Powerful Ideas

Audi is ablution the next alternative of its top-of-the-line model. With the R8, the cast has accustomed itself at the beginning of high-end sports cars from the actual alpha – and now come the R8 V10. Its 5.2-liter, ten-cylinder engine churns out 386 kW (525 hp) and 530 Nm (390.91 lb-ft) of torque, which makes for amazing performance. With above Audi technologies such as Quattro all-wheel drive, the failing aluminum body, the avant-garde all-LED headlights, and its arresting design, the R8 V10 takes pole position adjoin the competition.

The R8 V10 is the aftereffect of accumulative ability from Audi’s cord of Le Mans victories. Its by itself aspirated engine combines antagonism technology such as dry sump lubrication with FSI gasoline absolute injection. The ten-cylinder architecture is the absolute amalgam for absorbing top performance, boss affairs power, and low weight. Starting in 2009, this engine will as well prove its abeyant on the world’s racetracks – in the new R8 antagonism car Audi is developing for chump teams in acclimation with the GT3 rules.

The V10 engine in the assembly sports car will be about identical in architecture to the one in the antagonism version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 530 Nm (390.91 lb-ft) of torque, at 8,000 rpm its ability acme out at 386 kW (525 hp).

The specific ability achievement is 100.9 hp per liter of displacement – and anniversary hp has to actuate alone 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the adaptation with the six-speed chiral gearshift weighs alone 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) – that’s alone 31 kilos (68 lb) added than the V8. The Audi R8 5.2 FSI Quattro rockets from ought to 100 km/h (62.14 mph) in 3.9 seconds. In the adaptation with the sequentially alive R tronic it alcove 200 km/h (124.27 mph) in addition 8.1 seconds. Even again its active ability hardly lessens: it’s acceptable to ability a top dispatch of 316 km/h (196.35 mph). The immense force, the carelessness and the advance of the acceleration, additional the complete of the engine – all these impressions adhere into a amazing sports car experience. The V10 plays a concert with glottal bass tones and able top notes, which grows into a affected fortissimo as the engine revs up. This aureate dispatch doesn’t ability its absolute until 8,700 rpm.

The 5.2-liter power plant uses absolute bang according to the FSI assumption developed by Audi. An accepted abuse arrangement injects the ammunition into the agitation accommodation with up to 120 bar of pressure. Absolute bang reduces the susceptibility to animadversion and provides a assertive bulk of cooling through the dehydration of the fuel, which in about-face supports a top compression arrangement of 12.5:1. This in about-face contributes to above achievement and improves ammunition economy. The R8 V10 with R tronic gets by on an boilerplate of 13.7 liters per 100 km (17.17 US mpg).

The abstruse refinements of the long-stroke ten-cylinder engine cover dry sump lubrication, which allows the engine to be army low aural the chassis. The advanced butt bend of 90 degrees as well makes for a low centermost of gravity. The crankcase is a high-strength aluminum-alloy casting produced in a circuitous process. The abutting rods are fabricated of artificial steel, the pistons of aluminum. The four camshafts are chain-driven and anniversary is adjustable through 42 degrees. This provides abundant breadth in authoritative the valve timing. In aggregate with the straight, flow-optimized ducts of the assimilation manifold, this improves the allegation throughout the absolute acceleration range.

The R8 5.2 FSI Quattro has a six-speed transmission. A absolute and smooth-shifting chiral comes as accepted equipment. The consecutive R tronic is accessible as an option. The high-tech gearshift conveys an accurate antagonism feel – with the rocker switches at the council caster and the abbreviate alive times of usually beneath than one-tenth of a second. If the disciplinarian actuates the Launch Control affairs by acute a button, the R8 V10 takes off in a angry quick-start with electronically controlled annoy blooper – both with the R tronic and with the chiral transmission.

A accidental agency to the advanced advance in absorption and active assurance of the Audi R8 V10 over the antagonism is Quattro all-wheel drive – it’s the above technology abnormally for a high-performance sports car. Four-powered auto get added anchor than two. They accredit the disciplinarian to footfall on the gas eventually if advancing out of a curve. It’s not alone the absorption that benefits, but as well the axle dynamics and the stability.
