The M3 GT4, which benefits from all the race-ready hardware you’d expect in a vehicle prepped for a 24-hour enduro, made its debut at last weekend’s ADAC Westfalenfahrt at the ‘Ring, taking the win in the SP10 class and finishing 30th overall. The M3 will be back at the Nordschleife for the 24 hour race the weekend of May 23 and 24.

In any case, the new X3 will come equipped with a 2.0-liter direct-injected and turbocharged diesel engine that puts out 143 horsepower and 258 lb-ft of torque. More importantly, the 18d manages about 38 miles per gallon (46.5 mpg Imperial, 6.2L per 100 kilometers) in the EU combined cycle.

According to a post on the forums at GermanCarZone, BMW is currently working on a new version of its 3.0-liter six-cylinder diesel engine, which puts out 286 horsepower and 413 lb-ft of torque in its current, twin-turbocharged guise. To bump that power peak a bit higher, those crazy German engineers are rumored to be adding a third turbocharger that would boost horsepower to around 350.
