Mercedes' entry-level model, the C-Class is all-new this year, and it's competitors had better sit up and take notice.

In the past, the C-Class has been criticized by some purists for not handling firmly enough and not going fast enough. But in all fairness, these cars still sold like hotcakes.

Still, in this class, image is everything, and Mercedes is making sure the C-Class stands toe-to-toe with everybody else with some major improvements this time around.

The new C-Class comes in two distinct versions -- Luxury and Sport -- for a less-diluted presentation of each model. All the better for customers to get exactly what they want.

I can tell you that I've driven the Sport, and its a much tougher, all-business proposition.

The Sport model has 17-inch alloy wheels, a sport braking system, and a sport-tuned suspension that gives the car a lowered profile and offers firmer performance handling and dual exhausts.

A number of mechanical changes result in an overall sportiness: The steering ratio has been speeded up, which makes for better handling and quicker responses.

Inside, the seats are firm and supportive, but I found them to be uncomfortable after about three hours behind the wheel. I also found some of the controls needlessly complicated, such as the audio and climate systems incorporated in the center stack. These have been simplified from previous C-Class models, but they still could stand some re-evaluation in my view.

Although I didn't have a chance to drive the Luxury version, I think most Mercedes loyalists should feel right at home.

You can get two engines on the C-Class, which is rear-wheel drive, with an all-wheel-drive version expected this summer. There's a 3.0-liter, 228-horsepower V-6 in the C300 and a 268-horsepower, 3.5-liter V-6 in the C350. You can get the Sport and Luxury packages with either engine. Standard equipment includes all power accessories, along with traction and stability control and side curtain air bags, and keyless remote, cruise control and a tilt/telescope steering wheel.

Prices range from $31,975 to $37,275. Gas mileage ratings are 16 to 19 miles per gallon in the city and 22 to 26 miles per gallon on the highway, depending upon which model you choose.
