Officially unveiled as the Mazda MPS at the Geneva Auto Show earlier this month, the U.S.-spec MazdaSpeed3 will make it’s North American debut at the New York Auto Show on April 9th.

We don’t expect much to change from the Euro version, so don’t plan on any more power from the direct-injection 2.3-liter turbo-four. Power is rated at 260ps (256hp) and 280 ft-lbs of torque. Thankfully, the MazdaSpeed3 doesn’t need more power.

This is enough for a 0-62 mph run of 6.1 seconds, so the run to 60 might be able to get under the 6.0-second mark.

The engine does get some advancements though. For starters, emissions are reduced thanks to a new single-nanotechnology catalytic converter. As well, the 2.3-liter engine gets 0.5 liters/100km (0.1 mpg) better fuel economy.

In terms of technological advancements, the MAzdaSpeed3 has plenty of them. For starters the new engine features an advanced boost controller that reduces peaks for a more linear power delivery. The left and right drive shafts have been modified to reduce torque steer. The six-speed manual transmission now has wider ratios than before and the tranny uses a low-viscosity fluid to reduce shift effort.

With the new body and chassis, the 2010 MazdaSpeed3 is naturally better, however, it also gets large stabilizer bars, stiffer springs and shocks. As well, it now features 18-inch wheels with big brakes – 12.6-inches up front and 11-inches in the rear.

We’ll bring you full details in our New york Auto Show coverage starting April 8th.
