The Gallardo posted the second fastest lap time in Quattroruote's test track, right behind the Ferrari F430:
Ferrari F430: 1:17.4
Lamborghini Gallardo: 1:17.8
Chevrolet Corvette Z06: 1:19.5
Dodge Viper SRT10: 1:19.5
Ford GT 1:19.8
Porsche 911 Turbo: 1:20.0
I think the Gallardo did really well. I'm surprised about the 911 Turbo, though; I expected it to do better. But then again, we don't know what condition the tires of these cars were in.
Also, I really like the way the Ferari F430 looks with the black rear section... don't know what it's called. I've always thought that color scheme looked better on Ferraris than one solid color. It makes it look ten times better. The F430 needs it, or else it looks too plain.
