BMW M3 and M4 revealed

The high-performance BMW M3 Saloon and M4 coupe have been officially revealed, with both due on sale in June 2014. The M3 is now available only as a saloon, with the M4 taking the place of the old M3 Coupe.

The two cars feature a new in-line six-cylinder turbocharged engine, which replaces the larger V8 unit in the old M3 saloon and Coupe.

Despite the notable reduction in size, the new engine offers a slight upgrade in power over the V8, delivering 425bhp and identical performance in both cars.

Both take just 4.1 seconds to get from 0-62mph when paired with the optional automatic gearbox, while the manual model takes fractionally longer at 4.3 seconds. The top speed is limited to 155mph.

Fuel economy and CO2 emissions are also significantly reduced over the outgoing car's, by around 25%, with the automatic model emitting 194g/km and the manual 204g/km. Average fuel economy ratings are 34.0mpg and 32.1mpg.

To help get this power to the road, BMW has given the M3 and M4 Adaptive suspension as standard, which can be set in Comfort, Sport or Sport+. The electronic power steering can also be set in Comfort, Sport or Sport+ modes, modifying the level of assistance available.

The M3 and M4 also get uprated M Sport brakes, with carbon-ceramic brakes with gold-coloured calipers available as an option.

Visually, the two cars are differentiated from the standard 3 Series and 4 Series by a large front splitter, the M 'powerdome' on the bonnet, flared wheelarches, twin exhaust pipes and twin-stalk door mirrors. The M3 gets a lip spoiler on the boot, while the M4 gets an integrated rear spoiler, made from carbonfibre.

Carbonfibre also plays a big part in the look and weight of the cars – both get a carbonfibre-reinforced plastic roof.

There are a host of M badges on the door sills, gearlever and dials, while there's a leather M Sport steering wheel, bespoke, thin, lightweight sport seats and metallic steering wheel paddles if the automatic gearbox is specified.

The M3 and M4 go on sale on 21 June 2014, with prices starting at £56,175 and £56,635 respectively.
