BMW 5-Series

Already seen in the firm's 6-Series coupί¿½ and 3-Series saloon, this motor is constructed from aluminium to keep weight down. It uses Valvetronic technology to deliver a mix of strong performance and impressive economy.

From the outside, the 5-Series is the most successful interpretation of the current BMW design theme, especially with the M-Tech bodykit on our Sport test model. This comprises a small boot spoiler, deeper front bumper, side skirts and 18-inch alloy wheels, which make the most of the four-door's striking curves. It also gives the car the look of a mini-M5, even if it cannot match the flagship's dramatic performance.

Despite its more modest output, the 3.0-litre 5 feels easily quick enough when driven with enthusiasm. At low revs, the engine is virtually silent and very smooth, yet the tacho needle will happily shoot around to the red line, accompanied by a highly engaging six-cylinder exhaust note.

The slick six-speed manual gearbox makes getting the most out of the unit easy, whether you are high-speed cruising in top or trickling through traffic. Efficient brakes and a progressive clutch mean all the 5-Series' controls are positive and good to use, highlighting its credentials as a sporting saloon. This continues out on the road, as the ride is certainly on the firm side of comfortable. Sports suspension, combined with run-flat tyres, results in some bumps and surface imperfections being transmitted through the seat, but it never descends into feeling unpleasantly stiff.

The trade-off for this is superb road-holding, with minimal body roll in corners and plenty of grip. The steering is slightly numb, particularly around the dead-ahead position, which can mean a small degree of wander on motorways. Once into a bend, however, the set-up is accurate, making the car easy to place on the road. Inside, the sporty theme continues; the leather steering wheel, which is a smaller diameter than in the standard 5, and the matching gearknob display the M logo. Flashes of patterned silver trim further enhance the stylish cabin, which is finished well and laid out clearly. The simplified iDrive controller still takes some time to master, but otherwise the interior is comfortable and easy to use.

Combining the Sport package with the latest petrol engine brings the best out of the 5-Series, and only those seeking the ultimate super-saloon should consider a bigger-engined version.
