While the Zoom-Zoom tagline is still at play in Mazda's PR department (and in the radio display), the real buzzword for the 2012 Mazda 3 is "Skyactiv." This new powertrain finally catapults Mazda's popular 3 into the 40 mpg club by way of the new 2.0-liter 155-horsepower inline-4 and a six-speed automatic. Well, 40 mpg with the sedan. Our hatchback gets 39.

But what happens if you use those ponies in anger instead of in a delicate dance with mother nature? Does the new, greener Mazda 3 still return smiles at the track?

Comments:

Acceleration: Responds exceptionally well to pedal overlap on launch and even more with TC off, where it manages to chirp the tires on launch. Linear power delivery, smooth upshifts, but it sounds pretty loud/strained at WOT. Tall gearing for a six-speed (1/4-mile in 3rd!?)

Braking: Hard tires pumped up to 36 psi (manufacturer's spec) don't offer much grip, hence long stopping distance. Pedal effort was medium-firm and remained so despite some brake fade.

Handling:

Skid pad: Mild/moderate understeer, steering weight and resistance are appropriate at speed, but not much feel. With ESC on, it crept up to the point of understeer, then backed out of the throttle.

Slalom: Chassis feels better than the tires will allow. Feels like tires are inflated to 36 psi because they are. Lively, happy to play and rotate off-throttle, but there just ain't any grip. Precise friction-free steering without much feel.
