So this is what happens when you take an already solid vehicle and drop a fabulous engine into it— you get the Touareg TDI, a sport utility miracle that according to Edmunds testers can do it all. It delivers power, economy, refinement and versatility. Many of the accolades are awarded to the twin-turbocharged V10 diesel engine, which makes 310-hp and enough torque to snap the head right off of an unsuspecting passenger. An adjustable air suspension adds to the 'reg's adaptability, making it capable off-road and yet comfortable cruising on the interstate as well. The interior is likewise thoughtfully appointed with leather, wood, aluminum and power everything. The $57,800 base price isn't cheap, but if you're looking for an upscale SUV that can pretty much handle whatever task you throw at it, the Touareg will save you significant bucks over the likes of the Porsche Cayenne and Land Rover Range Rover, plus provide better mileage along the way.
