Which cars will be turning heads on the street this year? According to Playboy's "2008 Cars of the Year," a high-performance hybrid surges past competitors, a European import squeezes to the top, and a luxury carmaker provides one of the most fuel efficient and affordable vehicles on the road.

The selected cars were chosen by an expert team of automotive writers who traveled the world and test drove every new model hitting the showroom floor this year. The vehicles were taken on the sharpest turns, most challenging curves, and the steepest hills to properly separate the superlative from the mediocre. The vehicles featured in Playboy's January issue (on newsstands and at http://www.playboydigital.com/ Friday, December 7) include:
