Engine modifications for the 335i in the BMW 3-Series coupe and convertible
Although BMW is giving its 3-Series Coupe and Convertible versions a small update for 2011, the engine appears to be where the biggest changes will be made.
Although the 3.0-liter turbocharged in-line six in the 335i models continues to produce a powerful 300 horsepower and 300 pound-feet of torque, BMW claims that it is nearly a completely new engine with five more years of development, better fuel efficiency, reduced emissions, and improved responsiveness. The engine, which debuted recently in the 535i Gran Turismo, features full Valvetronic variable valve timing and a single twin-scroll turbocharger in place of the old twin-turbo configuration.
In the 3-Series variants, the highly modified engine will be mated to either a six-speed manual transmission or a six-speed Tiptronic automatic transmission. Both Coupes will once again have BMW’s xDrive intelligent all-wheel drive system.
The new 2011 BMW 335i has an electronically limited peak speed of 130 mph—or 150 mph when equipped with the Sport Package—and acceleration times of 5.3 seconds for the 335i Coupe and 5.5 seconds for the Convertible.
The basic proportions of the Coupe and Convertible haven’t changed in terms of design, but BMW has added a new headlight design, with Xenon Adaptive Headlights coming as standard on the 3-Series Coupe and Convertible in the U.S. Additionally, there are new fascia, taillight detailing, and side mirror revisions. For 2011, overhangs have been somewhat lengthened, and a BMW kidney grille with a chrome frame has been slightly wider to match a wider hood. Additionally, there are more contour lines on the rear air dam, and the taillights have been updated.
Both versions continue to be available with a variety of internal trimmings, including aluminum, Dark or Light Burl Walnut, Bamboo Anthracite, or Wood trim, and leatherette or Dakota leather upholstery in a variety of colors. Convertibles are available with special sun-reflective leather, which promises reduced surface temperatures.
Sea Blue Metallic, Vermillion Red Metallic, and Mineral White Metallic are three brand-new exterior colors.
This spring, the 2011 3-Series Coupes and Convertibles with revisions will be on sale. In 2012, a brand-new, third-generation 3-Series is also anticipated.
