New BMW M4 concept revealed.
BMW has closely previewed the new M4 coupe with a new concept car. The BMW Concept M4 Coupe offers a thinly veiled look at a production version that will launch at the Detroit motor show in January.
The concept, which will be unveiled at Pebble Beach this weekend, is billed only as a design study at present and, as such, gives no technical insight into the new M4. However, BMW sources have confirmed that the new M4 will return to straight-six petrol power, ditching the V8 of its M3 coupe predecessor.
As the 3-series coupe adopts the new 4-series name for its latest generation, so the M3 version adopts the M4 name. The M4 name will be used for the coupe and as-yet unseen cabriolet and Gran Coupe (four-door) versions of BMW’s new staple M car, with the M3 name remaining for the 3-series-based four-door saloon that will also be shown in Detroit.
All of these M models will share a new twin-turbocharged 3.0-litre engine, producing an estimated 450bhp. That’s up on the 414bhp produced by the outgoing normally aspirated 4.0-litre V8. Torque is also tipped to be around 66.4kgm, up 11kgm on the outgoing M3’s V8. Expect this to lead to a 0-100kph time of around 4.5sec and a top speed limited to 250kph.
Drive will be sent to the rear wheels through BMW M’s seven-speed dual-clutch gearbox, essentially the same transmission found in the M5 and M6. A manual version is understood to be off the cards for the first time in the M3’s history. A four-wheel drive version was understood to be considered but was rejected by M.
While BMW M has yet to go public on the exact driveline details, it has gone into detail on the design and look of the new M4’s exterior. Predictably, the ‘Aurum Dust’-coloured M4 gets a much more muscular and sporty look than the 4-series on which it is based.
The M4 is equipped with bi-colour 20-inch lightweight alloy wheels in BMW M’s traditional twin five-spoke design. Other lightweight features include a roof made from CFRP (designed to lower the centre of gravity), a material that’s also used for the rear diffuser. BMW is trying to get the M4’s kerbweight as close to the 1500kg mark as possible.
Also at the rear is a downforce-producing lip spoiler integrated into the bootlid, sets of twin carbonfibre tailpipes at each corner, a new bumper and subtly redesigned taillights.
BMW has yet to reveal the M4’s interior, but the usual M upgrades, including new sports seats, a new steering wheel and bespoke M aluminium and carbonfibre trim, can be expected.
Reworked suspension geometry, three-stage dynamic damping control and the adoption of electro-mechanical steering for the first time are among the spec highlights, alongside the latest version of BMW M’s mechanical differential.
