On the powertrain side, internal combustion remains the order of the day for now, but with much greater efficiency. New, clean diesel engines will be a major part of the company's goal of reducing fuel consumption by 30 percent or more in the next 5-6 years. New nano-material technology developed in-house is greatly reducing the need for precious metal catalysts, driving down cost of diesel after-treatment systems. Mazda has also been an early adopter of gasoline direct injection and will be adding dual clutch transmissions.
Ultimately, Mazda will end up adopting more electrification in its drivetrains, but that probably won't happen until the latter half of the next decade.
