2010 Mercedes-Benz E350 – Click above for high-res image gallery

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.

      How is 302-268= 14? That math is ALL wrong. The new engine makes 34 more hp than the old one. Come on guys, basic editing.

        Autoblog is incapable of facts checking or proofing. They make more amatuer mistakes than a highschool newspaper.

      I rented a 2011 E350 from Enterprise last month and for a V-6 it flat got up it went. I took the Mercedes up Hwy 1 in California from Morro Bay to past Carmel and ended in Santa Cruz,Ca. and then back to San Luis Obispo,Ca. 91/2 hours of driving. Got high 25 to 29 mpg.

        Yeah. My E350 has plenty of power on hand and gets 28-31 mpg on long-distance trips. Not bad considering it's rated at 18 & 26, I think. Still, this will obviously be an improvement; bully for 2012 buyers.

      This has become the better 5-series solution. The horsepower figures are 2 better than both of BMW's engines, which doesn't matter, but the 5-series is dull with heavy steering. Mercedes' V6 has been weaker than the competition's with less than 300hp, and the V8 with less than 400hp, but with this update, it's a winner. The V8 sounds great (V8 + twin-turbos, how could you go wrong), and I'm waiting for Audi's response. The new A6 already uses weight-saving tech, weighing about as much as the 3-series. Combined with the 300hp V6, it's a winner in the mid-sized luxury sedans, but I want to see the V8 A6 or if not, the S6. Somebody, do a comparo: BMW 535xi, Mercedes-Benz E350 4Matic, Audi A6 3.0TSFI and the Infiniti M37x. The Lexus GS is way too old for this.

      That instrument bezel looks like something out of a late 70's Volkswagen Rabbit ... kind of antiquated.

      check your math. the current E350 has a puny (for the money) 268hp which was no doubt making current owners embarrass themselves and potential owners walk out of the dealership.

      Why do I see some Lexus concept in that lower front end?

        Because Lexus copied it. The Merc has been on the market for a while now.

      Don't they have to change the name to E460 and CL460 to match the displacement?

        Logic would dictate that...but logic was clearly thrown out of the equation. I do love these cars, miles ahead of the jelly bean 5 series.
