In-house tuner fever continues its sweep through the automotive world this spring, with new models popping up everywhere from AMG to SRT, from Ralliart to Mazdaspeed. The latest speedster from Mazda is the Mazdaspeed 3, the fourth vehicle to come from the in-house team (following the Protege, the MX-5 Miata, and the recently-released Mazdaspeed 6.) Mazda says the vehicle, which is powered by the same 2.3-liter turbo from the 6, will provide "a double dose of Zoom-Zoom driving fun." That should be plenty of zooms, but unfortunately they will all be forced out through the front wheels, since all-wheel drive will not be borrowed from the Mazdaspeed 6. Interestingly, Dodge also opted to go with the lighter-weight but less-grippy front-drive set-up for the new Caliber SRT4 shown at the Chicago show. We'll see how both fast five-doors perform when we put them head to head some time next year.
