"   Browse expert reviews and compare info on Mercedes C-Class at the   Mercedes-Benz has truly mastered the art of creating beautiful automobiles with uncompromising luxury and high-performance driving dynamics. Case in point: the new C63 AMG. Unveiled over the July 4th holiday, this uber-powerful saloon isn&amp;#039;t your typical C-Class, Mercedes&amp;#039; smallest line of four-doors. It was created to challenge the BMW M3 for its undisputed King of the Road title\u2014a very formidable task, indeed. Lurking under the C63&amp;#039;s ridged hood is a powerful 6.3-liter that pumps out 451 hp and 443 lb.-ft. of torque. That&amp;#039;s enough get-up-and-go to propel the four-door from 0 to 62 mph in 4.5 seconds. Its top speed is electronically limited at 155 mph.  This fire-breathing road eater looks much different than its more sedate sibling. Up front, AMG gave it a more aggressive hood, custom front grille and larger air dams. Around back, you&amp;#039;ll find a small but slick looking rear spoiler and a large black diffuser with pronounced fins. The chrome tailpipes will make sure this speed demon pulls away on a solid note. Inside, there are new sports seats, and the steering wheel, which is equipped with paddle-shifters, has a flattened lower section. The seven-speed gearbox has three modes\u2014Sport, Comfort and Manual\u2014and now automatically blips the throttle for smoother downshifts. AMG modified the basic C-Class front suspension kinematics by designing an all-new, three-link front setup that widens the track by 35 mm and doubles the suspension&amp;#039;s wheel-locating rigidity. As part of the AMG sports suspension calibration, the C63 also gets a larger anti-roll bar, new suspension bearings and stiffer dampers. The C63 is also the first Mercedes with a new, three-stage ESP stability control system. In &amp;quot;ESP On&amp;quot; mode, understeer and oversteer are controlled by automatic application of the brakes and a reduction in power to the appropriate wheel. In &amp;quot;ESP Sport&amp;quot; mode, the system allows more drifting before it intervenes. &amp;quot;ESP Off&amp;quot; leaves braking and throttle control up to the driver. In both &amp;quot;Sport&amp;quot; and &amp;quot;Off,&amp;quot; full ESP kicks back the moment the brake pedal is touched; in all three modes, traction control remains active. Look for the AMG C63 to make its retail debut in Spring 2008. \u2014Chuck Tannert "^^<http://www.w3.org/2001/XMLSchema#string>
