It seems somehow unnatural but then again, the people who put themselves at risk to find new things and explore new places are also unnatural.

Alpina’s crew may be loaded with that kind of people as over the years they’ve constantly kept trying to improve the BMW powerplants for years.

Weirdly, at the moment, the most respected engine BMW is making is allegedly the 3.0 liter diesel they put in the 535d.

I’m a bigger fan of the petrol engine but it really a fabulous diesel. At this point Alpina turn it into the D5 BiTurbo.

Thanks to a couple of new turbos and an ECU remap the powerplant is now producing 350 horsepower and well over 442 lb-ft of torque.

Filter in the close ratio eight speed automatic gearbox and the Alpina D5 BiTurbo can now get from 0 to 62 in just 5.2 seconds and it has an updated electronic top speed limiter at 168 mph.

Despite the added power, the engine is praised as maintaining nearly the same fuel economy levels at 47.8 mpg in the sedan and 44.7 mpg in the Touring version.

There’s a good chance that a bit of turbo lag may happen but seriously, it’s a 5 second to 62 car that does well over 40 mpg.

Is there really that much more that you’d want from a car than what the Alpina D5 BiTurbo has to offer.
