What we couldn't manage to extract from our source is what kind of engine will find its way under the hood of the 2010 Mazda3 MPS / MazdaSpeed3. The most obvious choice is a turbocharged version of the 3's new 2.5-liter, 4-cylinder unit, but we wouldn't be surprised if Mazda takes advantage of its FoMoCo ties and uses a variant of the Focus ST / RS 2.5-liter turbocharged 5-cylinder engine that can deliver up to 300HP.
Insider: New Mazda3 MPS - Mazdaspeed3 will Debut in Geneva
Having already unveiled the sedan and 5-door hatchback versions of the '3', Mazda is now preparing to take the wraps off the sportiest variant of its C-segment model, the Mazda3 MPS or as it's known in the US, the MazdaSpeed3, at the 2009 Geneva Motor Show in March. While this is something that you may have heard as a rumor in the past, we are in a position to verify the debut as a fact.
