Two of the most promising green technologies that are currently infiltrating the automotive market are so-called stop/start systems and DSG transmissions. We're happy to report that the new Mazda3 is slated to get both of these eco-friendly features, with Mazda's proprietary Smart Idle stop/start coming before the end of 2009 on both the 1.6L and the 2.0L gasoline-fed four cylinder engines. That technology isn't planned to make an appearance in the European diesel models with their high-tech catalytic converters.
Mazda also says that it's planning to introduce dual-clutch gearbox technology in the 3, its most popular model. We're not yet sure what powerplants will be mated to the slick-shifting new transmission, or whether DSG will be paired with stop/start for the ultimate in affordable, current fuel-saving technology. Another unanswered question is if either of these bits will migrate from Europe and Japan to the United States, though we can certainly hope
