CHRYSLER'S NEW 8-SPEED TRANSMISSION BOOSTS MPG

摘要

Chrysler's new 8-speed transmission will debut on the rear-wheel-drive and all-wheel-drive V-6 Chrysler 300 and Dodge Charger models for 2012. The automaker said the new technology will be mated to the 3.6L V-6 Pentastar engine and will boost the 300 and Charger's fuel economy by 4 mpg. Both models will get an EPA-rated fuel economy of 31 mpg highway, 19 city. The transmission's wide ratio spread and improved efficiency boost city mileage by 5 percent when compared with the 5-speed automatic, according to Chrysler. In addition, Chrysler is making available all-wheel-drive variants of the transmission on both models for 2012, which is possible due to the transmissions modular nature. The all-wheel-drive system only engages when a driver needs it.
