Nothing sells like power and the Mazda3 with the turbocharged 2.5-liter 4-cylinder should be very popular with people that like cars. Mazda is shedding it's rowdy side for a more refined performance image. This is no Mazdaspeed3 and that's probably a good thing. Standard all-wheel drive tames torque steer and the suspension keeps things fun without any harshness. Tom Voelk checks out a fully loaded Premium Plus model. It's a step up from Civic, Corolla, Forte and Sentra and an alternative to GTI. Maybe even Audi A3, BMW 2-Series and Mercedes A-Class. Maybe.
