If the most purists and other “behemists” will swear by the 440i xDrive, aficionados of fuel oil will now have an equivalent option in terms of sportiness: a 440d xDrive version with a 6-cylinder Diesel.
The controversies surrounding the new BMW 4 Series and its grille are no longer too topical. That’s it, the pill has passed… or not for that matter, but we have stopped talking about it. However, since its inception, the new 4 Series has not been very well received. And to play provocation, the firm at the Hélice has just announced a news that will add water to the mill of the haters of the Series 4 : the arrival of a Diesel version with an M badge. Well, it is actually only an “M Performance” version, but it is enough to make the hairs of extremist purists stand on end.
Even if the new 4 Series Diesel is therefore not a true “BMW M” in its own right, it does have some tweaks from the brand’s “Sport” division. These include a set of “M Sport” components and a differential from the same source. In fact, the BMW Diesel M badge is not new in Europe: the manufacturer also has in its range of the famous M550d, a 5 Series station wagon with a 6-cylinder quad-turbo with 400 horsepower and 750 Nm of torque.
The M440d xDrive therefore has a 3.0-liter in-line 6-cylinder diesel engine delivering 340 horsepower and 700 Nm of torque. Power is sent to all four wheels via an eight-speed automatic transmission and xDrive all-wheel drive system. Perhaps this is enough to make disgruntled purists smile?
The Bavarian brand claims that the Sport Coupé in Diesel version can accelerate from 0 to 100 km / h in just 4.6 seconds. A fairly solid performance for a car that does not seek to be a real sports car but simply a good little GT. According to the WLTP homologation cycle, the car has an average fuel consumption of between 5.7 and 6.3 liters per 100 kilometers. Impressive considering the performance of this 4 Series M440d, even if this data must be doubled if you use all the resources of this Coupé.
There is also a less powerful but slightly less greedy model which joins the range. The 430d xDrive version is powered by a flanged version of the same engine block which develops “only” 286 horsepower. From 0 to 100 km / h it will therefore take 5.1 seconds, but the advertised fuel consumption is between 5.2 and 5.9 liters per 100 km. The two 3.0-liter diesel engines in the 4 Series Coupé feature a mild hybrid system with an integrated starter-alternator that relies on a 48-volt battery.
