The hardcore Mercedes-Benz E63 AMG isn't the only E-Class model that gets a new heart for the 2012 model year. According to our sources within Mercedes-Benz, both the E350 and E550 models will receive new powerplants currently found elsewhere in the automaker's lineup.

The base E350 will now be powered by the automaker's new 3.5-liter V6 with direct-injection, an engine that we recently tested in the C350 sedan and SLK350 roadster. Rated at 302 horsepower and 273 pound-feet of torque, the new engine provides power increases of 14 hp and 15 lb-ft over the current V6, while the use of direct-injection and a seven-speed automatic transmission will no doubt return improved fuel economy.

Moving along, the eight-cylinder E550 will ditch its naturally aspirated 5.5-liter V8 in favor of a twin-turbocharged 4.6-liter unit with direct-injection, currently found in the CL550 coupe. In the E-Class, this engine will be good for 402 hp and 443 lb-ft – improvements of 20 and 52, respectively.

Look for the refreshed E-Class range to debut this Fall.
