Known as the DISI, the direct-injection turbocharged 2.3-liter engine found in the MazdaSpeed3 is back in the all-new 2010 MazdaSpeed3, but very little has changed. One might even say it’s a DISI-ppointment.
You see, the new MazdaSpeed3 makes exactly the same amount of power with 260 ps (263hp) and 280 ft-lbs of torque. We were hoping that the new model would see a noticeable increase. It’s not like the MazdaSpeed3 needs it though.
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 starts to sound less like a disappointment. For starters the new engine geatures 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.

New Mazda3 MPS
The New Mazda3 Flagship
We are proud to introduce this new line-up of finely crafted cars that offer the exhilaration of driving pleasure and tangible attributes to excite drivers and once again exceed customer expectations. This is an exciting sports compact car that represents the Mazda brand – the all-new Mazda3.
Within the new line-up, we developed the Mazda3 MPS as the flagship model that pushes design and driving performance to the limit. And the Mazda3 with i-stop assumes its role as the environmental strategy car that embodies “Sustainable Zoom-Zoom”.
The new Mazda3 MPS builds on the popularity and recognition of the model it replaces, evolving the experience to an entirely new level of quality and pleasure with its emotional design and exhilarating performance. The “i-stop” differentiates itself from other recent efforts to deliver an environmental strategy car by implementing Mazda’s own environmental technology to achieve best-in-class fuel economy as it aims to greatly exceed the expectations of our customers.
These two models add extra value to the already strong appeal of the new Mazda3 series line-up. The new Mazda3 series takes a significant step ahead in both the realms of driving performance and environmental technology to lead the way toward a new generation of motoring.
