Spy Shots : Lamborghini Gallardo V8.

Our sources at the Nurburgring have photographed what may be a V8-powered Lamborghini Gallardo prototype.

A slightly revised front fascia, and a visibly reworked exhaust out back suggest that some engine changes are being explored. This Gallardo is reportedly being benchmarked with an Audi RS4, which is powered by a high-revving 420 hp V8 4.2FSI power plant. The RS4's V8 would be a logical engine choice if Lamborghini decides to move ahead with a slightly more sedate (and affordable) Gallardo variant.

Our 'ring spies tell us that this revised Gallardo is noticeably quieter than the typical V10-powered version, when running all-out on the track.
