BMW is putting the finishing touches on the 4-Series Coupe and Carscoops reader Niek recently spotted a prototype undergoing testing in France.

Dressed in heavy camouflage, the redesigned model will follow in the footsteps of the 3-Series and adopt an evolutionary design that blends upscale styling with sportiness.

While these pictures only give us a glimpse of the rear end, previous spy photos have shown the model will have a prominent grille which is flanked by slender headlights with integrated LED daytime running lights. We can also expect a rakish windscreen, an upward sloping beltline and a sporty rear end that echoes the 3-Series.

An assortment of engines will be available, but this particular prototype appears to be the M440i as it features the same exhaust system as the M340i. As a result, it’s likely powered by a turbocharged 3.0-liter six-cylinder engine that develops 382 hp (285 kW / 387 PS) and 369 lb-ft (500 Nm) of torque.

The engine should be connected to an eight-speed automatic transmission which can be paired to an optional all-wheel drive system. The latter configuration allows the sedan to accelerate from 0-60 mph (0-96 km/h) in 4.2 seconds, before hitting a limited top speed of 155 mph (250 km/h).

Besides the M440i, we can expect a 430i with a turbocharged 2.0-liter four-cylinder engine developing 255 hp (190 kW / 259 PS) and 295 lb-ft (400 Nm) of torque. It too will likely come equipped with an eight-speed automatic transmission and a choice of rear or all-wheel drive.

We’ll likely learn more about the 4-Series next week as BMW will reportedly use the Frankfurt Motor Show to introduce a 4-Series concept. It should be a thinly veiled preview of the production model which will be introduced sometime next year.

Thanks to Niek for sharing the photos!
