New BMW 3 Series Coupe and Cabrio 2010

Both cars get a decent design change almost invisible by a not trained eye. Anyway the biggest change took place under the hood.
New models get more powerful and efficient engines

The BMW 320d Coupé and Convertible models feature a new version of the familiar and parsimonious four-cylinder diesel engine – a unit that was already class-leading before this update.

It now delivers 184hp (up 7hp) and 380Nm of torque (up 30Nm). In the case of the Coupé this has shortened the zero to 62mph sprint by 0.4 seconds to 7.5 seconds, while at the same time reducing consumption by 1.2mpg to 60.1mpg and lowering emissions by 3g/km to 125g/km.

The values for the Convertible are zero to 62mph in 8.3 seconds, consumption is 55.4mpg and emissions 135g/km. The BMW Coupé is capable of reaching a top speed of 147mph with the Convertible attaining 142mph.

The six-cylinder 325d versions of both cars reveal similar all round improvements. Engine output is 7hp higher at 204hp, and torque is up from 400 to 430Nm enabling the Coupé to shave 0.4 seconds off its 2009 zero to 62 time, with it now arriving in just 6.9 seconds.

While fuel consumption remains the same at 49.6mpg, CO2 emissions are lower by 2g/km at 151g/km. The equivalent Convertible values are zero to 62mph in 7.5 seconds, 46.3mpg and 160g/km.

Nor has the flagship 335i derivative been ignored: although power and torque remain the same at a hearty 306hp and 400Nm, consumption and emissions have been significantly reduced. This has been made possible on this award-winning engine by combining a single turbocharger with VALVETRONIC variable valve management and High Precision Direct Injection for the first time.

For example, the Coupé’s fuel consumption is eight per cent lower at 33.6mpg while CO2 output drops by over ten per cent to 196g/km. Owners will also pay less tax each year since the 335i drops down a VED band to J. The BMW 335i Convertible also drops a VED band from L to K.

The BMW 335d Coupé has been refreshed resulting in an improved fuel consumption figure and lower CO2 emissions.

It now records 42.8mpg on the combined cycle, an improvement of 0.6mpg, and 174g/km. The latter point means the car now qualifies for VED band H, a tier below its previous position.
