News on the next-generation 2015 Audi R8 has been spilling forth for a bit now, but a report in Autocar has begun to put them into a single package. We knew that next R8 wouldn’t offer a manual option, only a seven-speed dual-clutch transmission, and that the monocoque would be a lighter, aluminum and carbon affair. Audi has apparently pegged a target weight of under 1,500 kilograms (3,300 pounds), meaning it will shed more than 135 kg (305 lbs.) versus today’s 4.2-liter V8 manual.
That will make the two engines in the next car – refined versions of the current naturally aspirated V8 and V10 – even more potent. Autocar didn’t mention an increase in displacement, but horsepower bumps were rated at 20 hp for the V8, to 450 hp, and 25 hp for the V10, to 550 hp. The GT will also benefit from 20 additional horses, getting 580 hp. More interestingly, neither mill will benefit from forced induction as Audi wants to maintain “the throttle response, the soaring nature of the delivery and the inherent sound.”
The evolution or disappearance of the sideblades on the “clean-sheet design” also wasn’t broached, but the trademark signifiers don’t appear in Autocar‘s rendering. The report states that it will take cues from the R8 e-tron (pictured), but they see intakes at the door shut-line, which feature very MP4-12C-like dual strakes. It’s only a rendering, but if sideblades are what you’re after then the future doesn’t look bright. We’ll see the sibling Lamborghini Gallardo replacement next year, a year before the R8 is shown in 2014.
