2010 Porsche 911 GT3

The new GT3 again leaves old 911s in the dust with an un-boosted 435 hp from its 3.8-liter flat-six. Although Porsche hasn’t yet quoted a specific number, the GT3′s mid-range torque response is claimed to be significantly fattened up.  The sprint to 60 miles-per-hour now takes a claimed 4.1 seconds with 100 mph coming in double that time.
