New Chrysler 200 Has Alfa Roots

Chrysler Group LLC is counting on a dramatic redesign and high-tech powertrain to help revive interest in its Chrysler 200 midsize sedan. The car debuted earlier today at the Detroit auto show.

The new 200 uses a version of Fiat Group's Alfa Romeo Giulietta architecture the "compact U.S. wide" platform that also carries the Dodge Dart small sport sedan and Jeep Cherokee SUV.

The 200 will offer a 2.4-liter, 184-hp MultiAir 4-cylinder engine or 3.6-liter, 295-hp V-6. Both will be paired with a 9-speed automatic transmission, which the company boasts is a first for the midsize segment. A fuel-saving all-electric, speed-sensitive steering system is standard.

The car's optional all-wheel-drive system freewheels when not in use to aid fuel economy. Chrysler says the system eliminates as much as 80% of parasitic losses by decoupling the power transfer unit, clutch plates and related pumps, driveshaft and rear differential when the car operates in front-drive mode.

The MultiAir valvetrain is operated with a hydraulically actuated intake valve system that can be electronically controlled for lift and duration. The system, in effect, uses valve control to throttle the engine.

The 200's new chassis features a MacPherson strut front suspension that has been retuned to minimize camber changes. The system is mounted on a cradle made of high-pressure die-cast aluminum. The rear suspension is a twist-blade multilink design with aluminum cross member intended to improve lateral control.

Chrysler says the car's stiffer chassis and upgraded suspension should significantly improve ride and handling.
