2011 Ford F-Series Super Duty, Best-In-Class Diesel. Is It?

American manufacturer Ford recently released a statement, praising its 2011 Ford F-Series Super Duty as delivering best-in-class torque, horsepower, towing and payload capability, all this while keeping a low fuel consumption and offering extended maintenance intervals

Strangely, though this is pretty much what we heard from GM referring to its 2011 Chevrolet Silverado pickups, we thought of giving Ford a chance to support their claims.

"The 2011 Super Duty is not only the most powerful, most capable and fuel-efficient heavy-duty pickup truck on the road, it performs the tough jobs with even more efficiency than ever before," said Doug Scott, truck group marketing manager. "Customers can be confident that Super Duty's class-leading capability comes with Ford's 'and solution' of best-in-class fuel economy."

Nothing too convincing so far. So we moved forward and took a closer look to the performance figures released by Ford. According to the carmaker, the 6.7-liter Power Stroke V-8 turbocharged diesel engine produces best-in-class 735 ft.-lb. of torque at 1,600 rpm and best-in-class 390 horsepower at 2,800 rpm.

The powerplant averages a 18 percent improvement for pickup models and up to 25 percent improvement for chassis cabs versus 2010 models in terms of fuel economy.

On the other hand, GM’s 6.6L Duramax turbo-diesel V-8 engine develops 397 hp at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm. But we’ll just let you judge for yourselves which one is the best-in-class...

"The new transmission is a 'clean-sheet' design, developed specifically to handle the significantly increased torque produced by the new diesel engine and the higher rotational speeds produced by the new gas engine, and to deliver the power to the wheels seamlessly and efficiently for heavy-duty truck customers,"
said Al Bruck, transmission engineering manager. "Each system and component was scrutinized to deliver optimum performance."
