2011 BMW 3-Series Coupe and Convertible Revealed - Web Exclusive

Jan 22, 2010

This week, BMW of North America has finally announced the newest updates to the ’11 3-Series Coupe and Convertible. This includes new styling changes to the 328i, 335i and new engine for the 335i. Expected to go on sale this Spring, be sure and stay tuned for pricing as the time gets closer.

Starting with the 335i, the car receives the new and improved N55 engine – a turbocharged, all- aluminum engine which features the same short block and 3.0 liter displacement of the N54. But five years after its introduction, the N55 has received improvements to make it more responsive, fuel efficient and clean-running.

The N55 features a inline-six that combines turbocharging, direct fuel injection and Valvetronic variable intake technology. It features a single turbocharger with a twin-scroll housing to boost performance and minimize lag. This housing design maintains separation between exhaust gases allowing the turbo to build pressure faster than the previous generation.

The engine is also lighter, weighing 150 lb less than the M3’s 4.0 liter V8. This lower weight makes the 335i better in fuel economy and weight distribution.

Valvetronic is a new feature that allows the engine to inhale air for combustion with no delay and reduced pumping losses. This allows the engine to make power quicker and reach peak torque at 1200rpm (200rpm earlier than the N54).

The power output has retained with 300hp and 300 lb-ft of torque with a 7000rpm redline.

The 328i is powered by BMW's 230hp, 200 lb-ft, 3.0 liter inline-sxi engine, known as the N52. The N52 achieves impressive progress on all performance and technology fronts, especially in its remarkably light weight of 357 lbs. An aluminum/magnesium engine block, hollow camshafts, plastic camshaft cover, improved combustion chambers, a further evolved Double VANOS[1], 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.
