Porsche 911 GT3 RS is powered by a 3.6L engine which can generate 415 bhp @ 7600rpm, while Lamborghini Gallardo Superleggera is powered by V10 that generates an incredible 530hp.

Which one is faster? Watch the video after the jump.

Lamborghini unveiled the Gallardo Superleggera last month and here is a testdrive. The Lamborghini Gallardo Superleggera is powered by a V10 engine generating 530hp boosting the Gallardo Superleggera from 0-60mph in just 3.8-seconds.
Although Lamborghinis are decidedly built for the road, the results of the Gallardo’s high-perfomance diet can best be seen (and heard) on the race track. This video comes courtesy of the Swedish Auto Motor & Sport, who took the new Superleggera out for a spin at the Phoenix International Raceway in Arizona.

Lamborghini Gallardo is taken up by Tiff Needell of Fifth Gear to race against a Ducati 999 motorcycle. Watch the video after the jump to see which one wins.
The Gallardo design vision was initiated in the year 2000. The challenging and simultaneously fascinating task of our designers was to cultivate the attributes from Lamborghini and combine them in an extremely individual packaging.

The Lamborghini V10 cylinder DOHC four valve V90 5 liter, 500 Hp, 510 Nm, is the concept solution for the high performance Gallardo. Instead of the more classical choice of a V72, an angle of 90 degrees was preferred in order to limit the height of the engine with advantages in the car layout (e.g. lower engine bonnet and better rear view) and in the lowering of the centre of gravity (i.e. better car dynamic characteristics).

Fifth Gear again takes a car for a test. This time the Lamborghini Gallardo SE. The car is powered by a naturally-aspirated 5L V10 that generates 500hp @ 7800rpm and 369 lb-ft torque @ 4500rpm — boosting it from 0-60mph in just 4-seconds flat. Watch the video after the break.
