For the 2011 model year BMW has decided to make some styling and engineering changes to the 3 Series Coupe and Convertible models.

A lot has been left unaltered, including the basic architecture of the car, rear-wheel drive layout (xDrive is available on the Coupe), suspension and steering systems, interior, and balanced weight distribution.

The engine for the 335i model is however all-new. Internally designated the "N55," this turbocharged, all-aluminum engine features essentially the same "short block" and 3.0-liter displacement of its predecessor, but benefits from five additional years worth of development and refinement. The result is an engine that is more responsive, more fuel efficient, and cleaner-running than its predecessor, but preserves the previous engine's power output - 300 horsepower and 300 lb-ft of torque, and a 7,000 rpm redline.

The new N55 is the first BMW inline-6 to combine turbocharging, High Precision direct fuel injection, and Valvetronic variable intake technology. It features a single, mid-sized turbocharger with a "twin-scroll" housing to boost performance and minimize the response lag. Thanks to its housing design which maintains proper separation between streams of exhaust gasses, the turbocharger builds up pressure much faster than previous-generation turbochargers, thus eliminating even the slightest tendency for lag.

The 328i is powered by BMW's 230 horsepower, 200 lb-ft, 3.0-liter inline-6 engine, known internally as the N52. An aluminum/magnesium engine block, hollow camshafts, plastic camshaft cover, improved combustion chambers, a further evolved Double VANOS1, higher fuel injection pressure, sophisticated engine electronics, an electric coolant pump, a variable-volume oil pump and an oil/coolant heat exchanger are the other weight-saving features and improvements of this engine over previous generations.

Stylewise the 2011 3 Series Coupe and Convertible models have been just mildly, but noticeably tweaked - that's if you have a 2010 sitting right beside for comparison.

The trademark BMW kidney grille is slightly wider in order to match the fractionally longer hood. These are complimented by revised headlights with the signature daylight running corona light rings.

The new design of the taillights is unique to the 3 Series Coupe and Convertible. The rear light cluster feature two-piece L-shapes and are further accentuated by a new color scheme. With two rows of light tubes that illuminate simultaneously, they create a night design with depth and dimension. Integrated flush into the body of the car, the lights are split into two sections and extend up the trunk lid, blending with the character lines from the side profile.

These styling tweaks have resulted in a slightly longer length and larger overhangs (29mm (1.14 inches) at the front, and 3mm (0.12 inches) at the rear)
