Fuel-miserly AWD on the way

Mazda says it is close to developing a fourwheel- drive system that uses less fuel than a lighter two-wheel-drive one. Mazda drivetrain assistant management engineer Tetsushi Marutani told Wheels his company’s goal was to have an efficient four-wheel-drive system “in the near future”. “Our goal is to beat the 2WD efficiency on dry pavement,” Marutani said, adding that the second generation of i-Activ all-wheel drive wasn’t far off. “If we get zero mechanical loss on mechanical system … we can beat 2WD [for efficiency].”
