BMW has given its long-running 3 Series a substantial makeover, introducing fresh styling, new technology and revised mechanicals while retaining the driving characteristics that have made it a favourite among sports sedan buyers.
Although the new model shares its Neue Klasse-inspired appearance with the electric i3, the petrol-powered 3 Series uses an updated version of BMW’s established CLAR architecture.
The initial range comprises the four-cylinder 320 and the more powerful M350 xDrive, replacing the outgoing M340i. A plug-in hybrid and a new-generation M3 will follow.
It’s the M350 that provides the clearest indication
It’s the M350 that provides the clearest indication of how far BMW has developed its popular sedan.
Under the bonnet is a turbocharged 3.0-litre straight-six petrol engine incorporating 48-volt mild-hybrid assistance. Producing 326kW and 580Nm, it sends power through an eight-speed automatic transmission to all four wheels.
BMW claims 0–100km/h acceleration in just 4.1 seconds, comfortably ahead of the Audi S5 and Mercedes-AMG C43.
Despite weighing 1860kg, around 100kg more than
Despite weighing 1860kg, around 100kg more than its predecessor, the M350 disguises its additional mass remarkably well.
Revised suspension geometry, a wider track, strengthened mounting points and upgraded anti-roll bars contribute to excellent body control and responsive handling.
The steering delivers reassuring precision, while the xDrive system provides substantial traction without eliminating the rear-biased character traditionally associated with BMW’s performance sedans.
Cornering grip is considerable, yet the car remains
Cornering grip is considerable, yet the car remains composed and predictable when driven enthusiastically. The engine’s broad torque delivery also makes rapid progress effortless, supported by smooth, responsive gear changes.
Importantly, this sharper dynamic character hasn’t come at the expense of everyday usability.
Around town, the M350 feels surprisingly manageable, with accurate steering and good outward visibility. The mild-hybrid system also allows limited engine-off manoeuvring at low speeds.
Ride comfort is generally impressive, although the optional 20-inch wheels transmit more imperfections over rough surfaces than smaller alternatives.
On the highway, the BMW settles into
On the highway, the BMW settles into a refined, relaxed cruiser, with subdued engine noise and an automatic transmission that keeps revs low.
Inside, the transformation is arguably more dramatic.
BMW’s new Panoramic iDrive system projects essential driving information across the lower windscreen, replacing the conventional instrument cluster. A large 17.9-inch central touchscreen handles most vehicle functions.
The interface responds quickly and offers extensive customisation, although the sheer number of settings creates a learning curve. The reliance on touchscreen controls also makes some adjustments unnecessarily complicated.
Cabin materials and presentation are suitably premium,
Cabin materials and presentation are suitably premium, with distinctive detailing helping separate the M350 from lesser variants.
Practicality is less convincing. Despite slightly larger exterior dimensions, rear legroom remains modest, particularly for the centre passenger.
Boot capacity has also fallen from 480 to 450 litres, leaving the BMW behind some rivals for luggage space.
Nevertheless, the latest 3 Series successfully balances performance,
Nevertheless, the latest 3 Series successfully balances performance, refinement and technology without losing its sporting identity.
The M350 is particularly impressive, offering performance approaching dedicated sports sedans while remaining comfortable enough for daily driving.
Verdict: BMW has strengthened an already compelling formula. Some ergonomic compromises and limited rear-seat accommodation prevent perfection, but the new 3 Series remains one of the most convincing driver’s cars in its class.
