It won’t be the first time that BMW’s M division has shoehorned a V8 into an M5, but it will be the first time that the iconic super saloon will feature forced-induction in lieu of a rev-happy, normally-aspirated engine.
According to the M division’s head of R&D, Albert Biermann, the rationale behind adopting forced induction is that it offers increased power and performance, whilst keeping emissions and fuel consumption as low as possible.
At the heart of the M5 Concept lies a twin-turbocharged 4,4-litre V8 developing 411 kW and 691 N.m of torque. It’s a revised version of the S63 unit currently doing service in the M versions of the X5/X6 and will be mated with a Getrag-sourced 7-speed transmission with paddle shifters. BMW has remained tight-lipped regarding performance figures, but it has been suggested that the new powerplant will help shave 0,2 seconds off the 4,7 second 0-100 km/h time set by the V10-engined car. Like many new BMW models, the M5 will feature a raft of fuel consumption/emission reducing BlueEfficiency features, such as brake energy recuperation and engine start/stop.
In BMW parlance, the term “concept” is a somewhat loose one – if you can remember the M3 Concept that the company revealed at the 2007 Geneva Show, you’ll recall that it wasn’t far-removed from the finished article.
As such, the M5 Concept, which makes its official debut at this year’s Shangai Motor Show, should be pretty close to the real deal.
Stylistically, the production M5 won’t be far-removed from its stable mates. Subtle changes include a deeper front spoiler with an enlarged air dam, slightly wider front wings, a small boot spoiler and chrome-accented side vents with integrated LED indicator lamps.
The wheels will be 20-inch items wearing 265/35 ZR20 rubber up front and 295/30 ZR20s at the rear. Although the F10 model is appreciably larger than its predecessor, it should bear a similar kerb weight to the outgoing car’s 1 830 kg.
