the BMW 335i models.

This past weekend BMW took the wraps off its refreshed 3-Series coupe and hardtop convertible models. In brief, the two-door variants of the 3-Series receive revised exterior styling and a new, more responsive and fuel-efficient single-turbo 3.0-liter straight-six for the 335i models.

In addition to these upgrades that we already told you about, the European-spec versions benefit from a tweaked diesel lineup and the presentation of a new-entry level model in the form of the 318i.

Beginning with the diesel range, the updated 2.0-liter four-cylinder unit in the 320d Coupe and Convertible models that complies with the EU 6 emission standards that won't go into force until 2014, now delivers 184HP and 380Nm of torque, up from 177HP and 350Nm.

In the case of the 320d Coupe, this has shortened the 0-100km/h (62mph) sprint by 0.4 seconds to 7.5 seconds, while at the same time reducing consumption by 1.0mpg US to 50 mpg US or 4.7 lt/100km and lowering emissions by 3g/km to 125g/km.

The values for the 320d Convertible are 0-100km/h (62mph) in 8.3 seconds, consumption is 46.1 mpg US or 5.1 lt/100km and emissions 135g/km.

BMW says that 320d Coupe is capable of reaching a top speed of 236km/h or 147mph with the Convertible attaining 228km/h or 142mph.
