Consumers these days are demanding new cars be clean, green, and efficient. Yet, they don't want to give up comfort and fun-to-drive in their pursuit to be responsible. And, no car lives up to that lofty standard better than our 2009 MotorWeek Drivers' Choice pick as Best of the Year, the Volkswagen Jetta TDI. The Jetta TDI is the first diesel to win MotorWeek's top honor, and the first clean diesel car to be available in all 50 states.

The heart of the Jetta TDI is Volkswagen's latest and most fuel efficient 2.0-liter turbocharged 4-cylinder diesel engine with direct fuel injection. It's highly effective after-treatment exhaust system requires no additives; so there's no hassle of filling a separate tank like most other clean diesels to date. With outstanding Government Fuel Economy rating of 30 city/41 highway, the Jetta TDI delivers hybrid-like economy without their complexity and battery concerns.

But that's just the half of it. The Jetta TDI also delivers plenty of spirited performance. With its 140 horsepower and copious 236 pound-feet of torque, this little sedan takes off like a champ. It handles quick on a straight line, is nimble and great fun on twisty roads. But the well tuned chassis also results in a smooth and quiet ride, which goes well with the TDI's comfortable and extremely well-equipped interior.

The cabin features a simple and clean layout, and ample passenger room. Standards include an 8-way power-adjustable driver seat, and a full compliment of airbags. Plus options like a 6.5 inch inch high-res navigation screen, a 30 GB harddrive, and iPod functionality. The large 16 cubic foot trunk prevents any shortage of cargo space.

Plus, it's affordable with a price tag that also puts many hybrids in the shadows.

Offering world-class efficiency, spirited performance, and a passenger-friendly atmosphere, the Volkswagen Jetta TDI is a no-compromise diesel alternative to the typical compact family car. And for that reason, it is our Drivers' Choice Best of the Year.
