2007 350z 3.5 V6
The only exterior change to the 2007 350Z may be subtle--a new hood with a slight center bulge--but there are big changes under that hood. Power is increased to 306 horsepower, a modest six-hp bump for manual-transmission Zs and 19 for automatics, but Nissan claims that 80 percent of the Z's prolific 3.5-liter VQ engine has been changed. This is the same update--and the same engine--that powers the Infiniti G35 sedan. The changes were extensive enough that Nissan renamed its celebrated V-6 "VQ35HR" (just rolls off the tongue, eh?). HR stands for "high-revving," reflecting the higher redline for the manual-transmission model, which increases from 7000 rpm to 7500. (The less-fortunate driver of an automatic 350Z can only rev to 6600 rpm, as with the previous engine.).
