Not just any diesel, but a straight-six with three turbos to deliver an astounding 800 Nm of torque.

Diesels might be under fire right now because of the multiple emissions scandals affecting several automakers, but that does not mean they’re on their way out. Sure, companies like Volvo and Porsche are seriously thinking about dropping development of engines running on Devil’s fuel, but it’s going to take a while until these will actually be eliminated.

BMW specialist Alpina is attending the Frankfurt Motor Show these days to show the diesel engine still has a future. Interestingly, the D5 S has different technical specifications depending on whether it’s the left- or the right-hand-drive version. The hottest of the bunch is the LHD model, which is described as being the “fastest series production diesel worldwide.”

At its heart is a straight-six 3.0-liter engine with a trio of turbochargers to deliver a total output of 388 hp (285 kW) between 4,000 and 5,000 rpm while the impressive 590 lb-ft (800 Nm) of torque kicks in from 1,750 up to 2,650 Nm. The diesel monster goes to 62 mph (100 kph) in 4.4 seconds and completes the 0-124 mph (0-200 kph) task in 17 seconds en route to 178 mph (286 kph). Bear in mind these impressive performance numbers are for the sedan, whereas the slightly heavier wagon is a tad slower.

Because of “engineering and packaging reasons,” the RHD model has a different drivetrain, thus not the same technical specs. It comes with a straight-six 3.0-liter with just two turbochargers and that gives it 326 hp (240 kW) between 4,000 and 4,600 rpm and 516 lb-ft (700 Nm) in the 1,750 to 2,500 rpm range. Still not too bad, right?

Since it is down on power, it’s no wonder this Alpina D5 S is slower than its LHD counterpart. Case in point, it needs 4.9 seconds until 100 kph and 20 seconds from a standstill to 200 kph. Take it to the maximum and it will top out at 171 mph (275 kph).

Both versions are already available on order and Alpina says it will begin customer deliveries in 2018. Go for the LHD sedan and you’ll pay €87,900, or if you would rather opt for the wagon, it starts off at €90,400 in the same LHD flavor.
