Auto Blog: MPG , Mazda , Geneva Motor Show Click above for high-res gallery of the new Mazda3 and MazdaSpeed3 The 2010 edition of the Mazda3 lineup will get rounded out at the Geneva Motor Show next month with the debut of the new MazdaSpeed3 and its 2.0L direct injected four cylinder with intelligent auto stop. The MazdaSpeed3 is the turbocharged high performance variant of the lineup. However, the more pedestrian versions are getting some interesting technology, at least for the European market. The Mazda3 i-Stop features a 2.0L direct-injected and normally aspirated four-cylinder engine. The MZR 2.0 DISI is the first appliaction of i-Stop, or Mazda’s intelligent auto start/stop system. Instead of using a starter/generator to re-start the engine, the engine is stopped in a specific position with the valves closed in one cylinder. The fuel is sprayed directly into the combustion chamber and then ignited to get the piston moving and re-start the engine. There’s been no word from Mazda on when or if we’ll see this system in the U.S. market, but Mazda claims the combination of i-Stop and DI accounts for a 12-percent reduction in fuel consumption for the 3. Check out the press release and a teaser video for the MazdaSpeed3 after the jump.
