At this week’s SEMA Auto Show GM will be emphasizing its ‘green’ performance credentials by unveiling a slew of modified cars capable of using E85 ethanol plus several ultra-efficient sports cars. In amongst the field of concept and production vehicles will be Jay Leno’s modified C6RS Corvette, an 8.2L beast with over 600hp on tap.
To live up to the green image, Leno and motorsport company Pratt & Miller modified the Corvette Z06 to run on E85 ethanol. More than merely a conversion of the stock LS7 engine to E85 capability, Leno’s alternative-fuel supercar is powered by a custom, 8.2L all-aluminum small-block V8 that pumps out approximately 600hp and 792Nm (585lb-ft) of torque.
