Ford Ups 6.7L Power, Eight Speeds for Ram Trucks and More!

Ford Ups 6.7L Power
When Ford introduced the 2011 Super Duty, the 6.7L Power Stoke turbodiesel was rated at 390 horsepower and 735 lb-ft of torque. Then came along General Motors and their 2011 trucks sporting a revised 6.6L Duramax with a Super Duty-thumping 397 horsepower and 765 lb-ft of torque. Not content to let GM hold the title, Ford has anounced that all new F-250, F-350, and F-450 Super Duty trucks will benefit from an engine management calibration that will up the Power Stroke output to 400 horsepower and 800 lb-ft of torque. Thanks to an all-new 6R140 TorqShift six-speed that has been thoroughly over-engineered, the Ford has room to grow. Best of all, early 2011 Super Duty 6.7Ls can be brought up to this revised spec with a quick trip to the dealer.

Eight Speeds for Ram
Chrysler and ZF recently announced that Chrysler has acquired the supply and manufacturing rights to ZF's excellent 8HP eight-speed automatic transmission for use in Chrysler vehicles. The 8HP offers a significant decrease in fuel consumption and lightning-quick 200-millisecond shifts, and is currently used by BMW, Land Rover and Rolls-Royce. According to ZF's website, the 8HP can handle up to 1,000 newton-meters, or nearly 750 lb-ft of torque, which makes for a real nice Ram transmission on paper, especially with next-generation Cummins turbodiesels on the horizon. The 8HP is also start/stop capable for further fuel savings. Chrysler will build the 8HP in Kokomo, Indiana, as soon as its $300-million-dollar renovation in the Indiana Transmission Plant 1 is complete.

Bigfoot Switches Sides
After 35-years of exclusively running Ford-bodied Bigfoot trucks, the original monster truck appeared as a Chevrolet during Major League Baseball's 81st annual All-Star Game festivities in Anaheim, California. Ford dropped the Bigfoot sponsorship back in 2007, leaving Firestone as the primary sponsor of the Bigfoot team. Firestone also happened to be a major sponsor of the All-Star Game, so Bigfoot 4x4 worked with MLB and the other major sponsor, Chevrolet. This one-off Chevy-bodied Bigfoot is also Chevy-powered because Bigfoot 4x4 doesn't believe in brand mixing. There are no current plans to switch the rest of the Bigfoot fleet over to Chevrolets.
