The all-new Mazda3 Sedan revealed its ‘smiley’ face to the public for the first time today at the opening of the 2008 LA Auto Show. The current ‘3’ is Mazda’s best-selling vehicle worldwide with around 1.8 million global sales since its launch in 2003 and the Japanese firm hopes that the second generation model will do even better. Aside from the new sheetmetal and the overhauled interior the 2010 Mazda3 also sports a new 2.5-liter engine and new transmissions.
