The new BMW 4 Series Coupe will be officially unveiled at the Frankfurt Motor Show in September, before going on sale in the UK from 5th October 2013.

The two-door coupe will be available with a choice of three engines initially, coupled with either rear-wheel drive or xDrive all-wheel drive.  Three more engines will follow a month later.

Five trim levels – SE, Sport, Modern, Luxury and M Sport – will be available, and prices will start from £31,575 for the BMW 420d SE Coupe.

The BMW 4 Series is 26mm longer than the 3 Series Coupe, and features a 50mm longer wheelbase.  It’s also 43mm wider, with both front and rear tracks increased by 45mm and 81mm respectively.  The roofline is 16mm lower, too, thanks largely to the lowered suspension.

Xenon headlights are standard, with Adaptive Headlights and Adaptive LED Headlights as an option.

BMW says that the springs, dampers, and overall geometry have been tuned to a specification unique to the 4-Series, in an attempt to create a more engaging driving experience.  Strengthening elements have been added to help increase steering feedback.

At launch, three TwinPower Turbo engines will be available, with three more to follow within a month.  An eight-speed automatic transmission will be available on all models (standard on the 430d and 435d xDrive), while xDrive all-wheel drive will be offered on the 420d and 420i.

Initially available will be a 2.0-litre four-cylinder 428i petrol, 420d turbodiesel and 3.0-litre six-cylinder 435i.

The 306hp 435i features twin-scroll turbocharging, and delivers its 400Nm maximum torque from 1,200rpm all the way to 5,000rpm.  The 245hp 428i offers its maximum of 350Nm from 1,250rpm to 4,800rpm, while the 184hp 420d delivers a healthy but narrower 380Nm from 1,750rpm to 2,750rpm.

Six-speed manual transmissions are standard, while the optional eight-speed automatic includes a Launch Control function and steering wheel-mounted paddles.  Surprisingly, the automatic models are more efficient than their manual counterparts – the 420d’s emissions drop to 121 g/km in auto form.

Following in November will be a 184hp 2.0-litre four-cylinder 420i, as well as 258hp 430d and 313hp 435d six-cylinder diesels.  The latter two come with eight-speed auto transmission as standard, while the 435d is an xDrive only model.

Standard equipment on all models includes front and rear parking sensors, heated front seats, multi-function steering wheel, Xenon headlights, DAB radio, Dakota leather upholstery, dual-zone air conditioning, cruise control, Bluetooth connectivity, 6.5-inch colour screen with iDrive, and automatic headlights and wipers.

Six-cylinder models add electric front seats and metallic paint as standard.

In the UK, all 4 Series models will feature 18-inch alloy wheels and sports seats as standard, while Luxury and M Sport models add BMW’s Business Media package (sat nav and telephony).  M Sport models also include M Sport suspension, a three-spoke steering wheel, aluminium interior trim, unique M Sport alloy wheels and an aerodynamic body kit.
