In an effort to suck some flab from the company’s flagship supercar, Audi will utilize the 23 percent carbon fibre spaceframe body from its stillborn R8 e-tron, along with the electric car’s glass fibre-reinforced plastic (GFRP) suspension springs and anti-roll bars, carbon ceramic brakes and titanium rear hubs. Furthermore, the carbon fibre-reinforced plastic (CFRP) hood and roof from the R8 LMS also contribute to the 2015 R8’s sub-1,500 kg weight.
And, rather than reduce capacity and add forced induction to the engine range, Audi will revise its V8 and V10 units with improved outputs of 336 kW (450 hp) and 425 kW (570 hp) respectively. Cylinder deactivation and stop-start functions aid a 10 percent improvement in fuel consumption over the outgoing vehicles.
