We sure hope you BMW fans out there like your four-cylinders with forced induction. According to Autocar, the German automaker has committed to strapping a turbocharger to all of its four-cylinder engines in the near future. The report cites "company sources" as saying that the company plans on using turbo four-pots for applications requiring up to 241 horsepower. Above that magic number, the tried and true inline-six will step in to take over.
Furthermore, each of the company's four-cylinders will all be based on the 2.0-liter aluminum block with different turbochargers and engine management to help crank out different levels of punch. Autocar says the block will use a sprayed-iron liner that's just .3 mm thick instead of the conventional 1.5 mm cast-iron cylinder sleeves for added durability and reduced weight.
Chances are we'll see the first iteration of that lump crop up in the upcoming X1, which Autocar says is set to debut sometime later this week. It will pack the most potent variation of the four-cylinder, though BMW has rated the mill at around 245 horsepower thanks to a twin-scroll turbocharger, variable valve timing and a high-pressure fuel injection system. What's a few ponies among friends?
