The inherent driving traits of the M3 saloon prove every bit as compelling as those of the M4 coupé. Setting the tone is BMW M division’s new twin-turbocharged 3.0-litre in-line six-cylinder engine with its headline 425bhp output (which is ). With huge low-end shove, it is incredibly easy to live with.
It also serves up the sort of storming in-gear qualities that make the old naturally aspirated 4.0-litre V8 appear a little weak by comparison. Just don’t expect the blown unit to offer up same razor-like throttle response or alluring aural qualities as the engine it replaces.
Can the BMW M3 match the M4 in reality?
Purists will go for the manual – they almost always do. But the optional dual-clutch automatic M-DCT gearbox provides the M3 with the ease of usability to match its fervent on-boost accelerative properties, leading to the very same set of official performance figures as the M4 coupé: 0-62mph in 4.1sec and the standing kilometre in 21.9sec. With the manual, it takes 0.2sec and 0.3sec longer respectively.
The perception of equal performance is backed by BMW M division's development boss, Albert Biermann, who claims the M3 and its M4 coupé sibling boast the same Nürburgring lap time. “We’ve run both cars extensively, both together and in separate tests," he says. "Apart from nuances in driving style between our engineers, they are all but inseparable in lap time.”
Adding to the appeal is Drive Performance Control, which allows you to alter the character of the M3 over a wider range than before. Accessed via three buttons on the centre console, you get the choice of Efficiency, Sport and Sport+ modes for the throttle mapping together with Comfort, Sport and Sport+ modes for the damping properties and electro-mechanical steering.
Where the BMW M3 impresses most is with its ability to be fast and vivid one moment, and comfortable and relaxing the next. The inherent practicality of the four-door body and a 480-litre boot only adds to its everyday appeal. Along with its enticing long equipment list. As standard the M3 gets 19in alloys, LED head and rear lights, cruise control, an active differential, adaptive suspension, an aggressive 'M' bodykit and a rear spoiler, while inside occupants are treated to dual-zone climate control, BMW's excellent iDrive system with an 8.8in screen, sat nav, DAB and ConnectedDrive services, Merino leather upholstery and heated front seats.
and you'll get 20in alloys, track specific springs, dampers and anti-roll bars, a black chrome quad exhaust system and an improved audio system.
It's also cheaper than the M4 coupé, if only just at £57,905 as opposed to £58,365. If you’re in the market for a performance car that can handle family transport obligations, it’ll be hard to ignore.
The only caveat with the M3 is that it may be hugely entertaining when its unleashed on the track and equally comfortable and civilised at all other times, but the new twin-turbo, straight six engine may lack the charisma that and offer in abundance.
