2007 Nissan 350Z in Sacramento, California

The Nissan 350Z was extensively upgraded for 2006, and for 2007 Nissan turned its attention to the engine, which has been redesigned for substantially more power. This brought a styling bonus. Because the more powerful engine needed better breathing, the 2007 Nissan 350Z gets a new hood and front fascia that sucks in more air.

The new 3.5-liter V6 engine is used in all seven models of the 350Z. Something like 80 percent of the parts in the engine are new for 2007. On paper, the 2006 engine was rated 300 horsepower. For 2007 the output has been raised to 306 hp, but the increase is more than 6 hp because beginning in 2007 there's a more stringent industry standard for measuring horsepower, as determined by the Society of Automotive Engineers.

The Nissan 350Z is fast, fun, and pure sports car. It costs about 10 times as much as the original 240Z, which went for about $3500, but in today's dollars that's only twice as much (as calculated by the Consumer Price Index). But you get about 10 times the car, so you're still way ahead.
