We're not sure about you, but the looks of the 4 Series coupe are growing on us. Those buck-toothed grilles aren't too bad in person, and they certainly work better on the Gran Coupe body style, which should be revealed soon. The price is a little worrying, but fans of oil-burning engines have had an altogether different gripe. One thing that has been missing from the range, however, is a proper, torquey, diesel engine, but BMW has just remedied this fault with not one but two new turbodiesel offerings, both of which are signature straight-sixes, and both of which offer impressive performance.

We'll start with the less powerful engine first, but both are 3.0-liter inline sixes. The lesser engine will be coming in the new 430d xDrive coupe and offers 281 horsepower with 479 lb-ft of torque. According to BMW, this model will be able to achieve WLTP figures of between 5.2 and 5.2 l/100km. We'll have to wait and see if it comes to the USA and what it will score on the EPA's city/highway/combined cycles, but with this model capable of hitting 62 mph in just 5.1 seconds, we certainly hope we get to have a go. Not as much as we hope to experience the other new offering, however.

The other new engine in the range is fitted to the new M440d xDrive. It too has a 3.0-liter turbodiesel straight-six, but in this case, output is an impressive 335 hp. It also develops a strong 516 lb-ft of torque, but as it's an M-enhanced variant, this model will also gain a carbon-fiber roof as well as the M sports package and the M sports differential for better handling. It'll be great in a straight line, promising 4.6 seconds to get to 62 mph. There's no word on whether this model will reach American shores either, nor how much either choice will cost, but we're glad they exist at all.
