MONTVALE, N.J. – Mercedes-Benz is making its 4Matic all-wheel-drive system standard equipment for the 2009 CL550. The system, which debuted in 2007 in the S-Class sedan, splits torque 45/55 front/rear via a limited-slip center differential within the car’s transmission housing, according to www.autoweek.com.  

In addition to getting 4Matic, the CL550 trades in its Airmatic suspension for Mercedes’ Active Body Control system. The car also gets standard heated and ventilated front seats and keyless ignition. However, Mercedes said that even with all of the added equipment, the price should remain near its current level, which is close to $105,000. The rest of the lineup, including the V-12-powered CL600, CL63, and CL65 AMG models, continue as rear-drivers with the Airmatic suspension. All 2009 CLs go on sale this summer.
