What is it?
A pretty important model for BMW. Last year, the firm shifted around 400,000 3-series models across the globe, making up 37 per cent of all BMW sales. A revamp for 2010 is designed to keep the 3-series family competitive.
One of the youngest 3-series variants is the E92 Coupe, which arrived four years ago. For the 2010 model year it's been given an overhaul, with nip-and-tuck cosmetic changes (new bumpers and sill covers, and LED-equipped head and tail-lamps) and the option of a number of revised engines.
What's it like?
On a freezing day in Munich we tried the 335i coupe, which is equipped with a new version of BMW's classic turbocharged straight-six engine and, in the case of our test car, a new seven-speed double clutch gearbox that adds £1640 to the list price.
Unlike its predecessor, this engine has a single turbocharger, rather than a pair. The new unit's 'TwinPower' design means the turbo is double-sided, with each set of blades spun up by the exhaust gases from three of the engine's six cylinders.
In addition to the high-pressure direct fuel injection, this engine now gets BMW's Valvetronic variable valve timing system. Although the engine's power and the car's performance remain unchanged from the previous model's, the fuel economy has been improved by eight per cent.
With 302bhp on tap and a diesel-like 295lb ft of torque (delivered completely flat from 1200rpm to 5000rpm), the 335i's performance is predictably impressive. However, our car's engine was a touch gruff under hard acceleration; it's not clear whether the direct injection system or just engine tightness was to blame.
The seven-speed dual-clutch 'box is excellent, being pretty indistinguishable from BMW's smooth auto boxes and avoiding the low-speed hesitation that affects VW's seven-speed DSG unit.
Should I buy one?
The 335i is quick, focused and well balanced. However, the age of the basic E90 3-series is beginning to show through.
Our car suffered from quite a bit of wind noise around the pillars and the overly heavy controls (especially the steering) made rowing the car along a tiny bit of a chore.
