Best Economy Car:--- Mazda3
High-value 3i models feature a fine 2.0-liter, 148-hp four-cylinder engine; 3s versions, with their bigger 160-hp four, are even stronger

Best Family Sedan:---Honda Accord/Acura TSX
Don't be fooled by the Acura's four cylinders and 200 hp: It's a serious sporting machine. And the Honda's low-key looks disguise its skillful handling.

Best Small SUV:--- Jeep Liberty
Big news is the addition of a frugal turbo-diesel version rated at 22 mpg city/27 highway, compared with 17/22 mpg for the 210-hp, 3.7-liter gasoline V-6. The 2.8-liter diesel produces 160 hp and class bests including a 500-mile driving range and 5,000-pound towing capacity

Best Luxury Car:--- Audi A6
Audi's new direct-injection, 255-hp V-6 or a mighty 335-hp V-8; both are mated to standard Quattro all-wheel drive

Best Crossover:--- Scion xB
With just 108 horsepower on tap, the xB dawdles a bit, and gets mildly buzzy above 70 mph. But it's more fun to drive than you'd expect, and its low-rider stance feels steady and safe.
