Citing inside sources from BMW, British magazine Autocar is reporting that all of the Bavarian automaker's future four-cylinder engines will benefit from turbocharging technology. This includes all four-pots with outputs up to 245 horsepower, with the new straight-six engines taking over from there.Following lower-powered units are expected to get a single conventional turbo instead of the twin-scroll technology. The new turbocharged four-cylinder units will make their debut on the next generation of the 3-Series, expected in 2012.
