specs and comparrison

im looking to buy a mazda 3 but i cant really tell the difference between the SPEED, I, S, GS, GT. so far ive learned the S is a 2.3, and the I is a 2.0, but im not sure if the SPEED is stock turbo. Also are there any AWD. :licka:

you got the I and S correct. The speed 3 IS a stock turbo and to answer the last part of your question.......We wished it was AWD!!! NO it is FWD.
