The controls for air conditioning, the audio and navigation systems are within optimum visibility and within easy reach for the front passenger. Several controls and switches including the door handles and gearshift lever are finished in a sophisticated Pearl Gray metal to ensure a premium tactile feeling with elegant looks.

The side panels display a smooth and sweeping design flow that extends from the dashboard all the way to the backrests on the two rear seats. The center console also extends all the way to the rear, serving as a storage compartment between the rear seats. Ambience lighting, mounted on the door and rear side panels, projects a warm and indirect light effect.


New engines for a perfect combination of muscle and refinement

Two versions will be available in the US. The powerful 335i Convertible features BMW's newest inline six-cylinder engine with twin turbochargers and an intercooler for 300 incredibly flexible horsepower, thanks to high precision direct fuel injection with piezo injectors. The 328i Convertible features a 230-hp 3.0-liter inline six-cylinder engine with Valvetronic technology and aluminum/magnesium construction.

The more sporting version of the new 3 Series BMW Convertible, the 335i, is powered by the world's first inline six-cylinder with Twin Turbo and High Precision Direct Injection technology and an all-aluminum crankcase. Rated at 300 hp at 5,800 rpm and 300 lb-ft of torque at 1,400 - 5,000 rpm, this 3.0-liter engine offers cutting-edge performance thanks to the theories behind BMW's Efficient Dynamics. Using high-tech materials allows the engine to be a lightweight performer, which helps BMW achieve near 50/50 weight distribution on this and all of its vehicles. Low inertia turbocharger internals and high precision direct fuel injection makes turbo lag nearly non-existent as peak torque starts at a mere 1,400 rpm. High precision direct injection is also ideal for lean burn operation. In the lean burn mode, various intercepting layers of the fuel and air form within the combustion chamber. The fuel/air mixture is therefore particularly rich and ignitable only in the direct vicinity of the spark plug and once ignite,the flame travels to the leaner layers further from the spark plug for a clean, smooth and consistent combustion process. Redline is still an impressive 7,000 rpm and compression ratio is 10.2:1. Typical of a BMW engine are incredible smoothness, fast-revving response and refined power at all engine speeds.

2007 BMW 335i Convertible accelerates to 60 mph in just 5.5 seconds for the six-speed manual, and in 5.7 seconds for the six-speed Steptronic automatic transmission. Top speed is electronically-controlled to 130 mph and on vehicles equipped with the Sport Package, top speed is governed at 150 mph.

The 328i Convertible is equipped with a the 3.0-liter inline six-cylinder engine that delivers 230 smooth horsepower at a peak of 6,500rpm and 200 lb-ft of torque at 2,750 rpm. Featuring BMW's innovative Valvetronic engine system, which eliminates the conventional throttle body for throttle control, efficiency and power are available over a broader range for silky-smooth operation. The magnesium/aluminum block is a perfect example of BMW Efficient Dynamics where lightweight technology is at work, making the 328i unique against its competition. The electric engine coolant pump also demonstrates one of the many examples where efficiency can be felt at the accelerator pedal. Speaking of which, acceleration from 0 to 60 mph comes in a spirited 6.7 seconds for the six-speed manual and in 7.2 seconds for vehicles with the Steptronic six-speed automatic transmission. Like the 335i, the 328i is limited to 130 mph or 150 mph if equipped with the Sport Package.


New automatic transmission with optional shift paddles

A thoroughly enhanced six-speed automatic transmission is available as an option on both models to meet the greatest demands for comfort and performance. A quicker and more responsive hydraulic control system, together with an innovative new torque converter and significantly enhanced control software ensure reaction times that are 40% faster than conventional automatic transmissions.
