With the 2003 debut of the 4MATIC all-wheel-drive system in its C-Class and S-Class lines, Mercedes-Benz says it is anticipating an emerging trend in the luxury car market. The company is announcing the return of 4MATIC to its E-Class line with the world premiere of the 2004-model E-Class wagon at the North American International Auto Show in Detroit. As a result, when the wagon goes on sale later this year, Mercedes-Benz says it will be offering all-wheel-drive versions of all its sedans and wagons for the first time ever.According to the company, with negligible weight and fuel-efficiency tradeoffs, go-anywhere full-time four-wheel-drive systems provide year-round traction and stability benefits, on both wet and dry roads. Mercedes-Benz first introduced 4MATIC-equipped cars in 1989.According to the company, the full-time four-wheel-drive system used in all Mercedes-Benz cars and sport utilities features a mechanical center differential that can vary front-to-rear torque distribution for on-road handling, and improved traction in a wide range of conditions.In addition, the system includes four-wheel electronic traction control that keeps the vehicle going even if only one wheel has traction. With a mechanical all-wheel-drive system, four-wheel traction control eliminates the need for complicated locks or limited-slip devices. However, the G-Class is the one Mercedes-Benz that is also fitted with three differential locks for an extra measure of heavy-duty off-road performance, according to Mercedes-Benz.While 4MATIC cars use a single-range five-speed automatic transmission, Mercedes-Benz sport utility vehicles add a two-speed transfer case that actually provides ten forward gears, including a low range for control going up and down steep grades. When low range is engaged, a modified transmission shifting program and ABS mode are engaged for optimal off-road performance.According to the company, under normal conditions, Mercedes sport utility vehicles distribute torque nearly equally between the front and rear wheels. On the other hand, 4MATIC-equipped cars come with a planetary gear set within the center differential that begins with 35-65 percent front-to-rear torque distribution. To skilled drivers, this rear-bias all-wheel-drive system feels much like rear-wheel-drive Mercedes-Benz cars, in which subtle throttle steering effects can enhance handling, especially in spirited driving.About Mercedes-Benz USA
