The Lamborghini Gallardo V8 was caught testing at the rburgring race track. As you can notice from the video, the V8 Gallardo will use the same exhaust note as the Audi R8 and the exhaust pipes are smaller than on the V10 Gallardo.
Lamborghini will borrow the current V8 engine from the R8 for a more affordable Gallardo. The new supercar will sit bellow the current V10 Gallardo, but above the current Audi R8. The V8 will bust around 430 hp in the new Gallardo, but with the low weight of the supercar, the performance will be better compared to the R8: 0 to 60 mph in 4.5 seconds and a top speed of 195 mph.
