The horsepower (and more importantly, torque) wars are heating up between GM and Ford. Last month Ford released the power numbers for its new 6.7-liter Power Stroke V8 in the all-new F-Series Super Duty, rating the truck at 390-hp and 735 ft-lbs of torque. Then just a few weeks later GM announced its numbers for the 6.6-liter Duramax V8 in the new 2011 Chevy Silverado and GMC Sierra HD pickups at 397-hp and 765 ft-lbs of torque.

Word comes from the folks at that Ford isn’t prepared to sit back and take second place, with an increase in power numbers due out as early as next year. There’s even a suggestion of 400-hp and 775 ft-lbs of torque. Ford certainly has the upper hand as the all-new Power Stroke 6.7-liter has plenty of potential left in it, while the 6.6-liter Duramax is a revised version of an older engine design and has used up much of its potential already. The problem will be increasing power while hitting fuel economy and emissions targets.

Ford’s motivation is clearly from the marketing side here. Sure added power and torque make for a more capable truck, but Ford already leads GM in both towing and payload, even with the lower engine numbers. The new Duramax Silverado HD can tow up to 20,000 lbs and has a payload rating of 6,335 lbs. The F-Series Super Duty (F-350) is rated at 21,600 lbs and a payload rating of 6,520 lbs.

This battle is just the latest in a horsepower war between GM and Ford, with GM planning to deliver a more powerful V6 Camaro next year, while rumors suggest a twin-turbo V6 is on the way to rival Ford’s EcoBoost.

Ford has just released seven new high quality videos about the new 2011 F-Series Super Duty (and its all-new 6.7-liter Power Stroke V8) that debuted last week at the Texas State Fair. Hosted by Mike Rowe from Dirty Jobs, the short programs examine the the new truck, its powertrain and incredible capability.

If you like trucks, diesels or just great engineering, these spots are all worth a look. They take you through the basics of the (complex) new diesel engine, as well as innovative features like Live Drive PTO (Power Take Off), which allows auxiliary equipment like snowplows or salt spreaders to be powered through the transmission.

The only thing Ford hasn’t told us about the all-new 2011 Super Duty is exactly how much power the new Power Stroke 6.7-liter V8 motor makes.

Report: 2011 Ford Super Duty Will Debut at Texas State Fair

New model to get completely redesigned 6.7-liter Power Stroke V8

After releasing some exciting technical info on an all-new Power Stroke engine for the 2011 F-Series Super Duty, Ford has now announced plans to officially unveil the new diesel pickup at the Texas State Fair, with sales starting in the Spring of next year.

Under the hood of the new F-Series Super Duty will be a revolutionary new 6.7-liter Power Stroke turbo-diesel engine. The all-new engine promises a, “significant improvement in torque, horsepower and fuel economy,” says Ford in a press release, stating that this new F-Series Super Duty would continue to be a class leader in both payload and towing. It will also be significantly quieter than past diesels.

Numerous high-tech innovations have been employed in building this new engine, starting with a compacted graphite iron (CGI) engine block that Ford says is twice as strong as standard iron blocks. This was deemed necessary due to the increases in power output.

The new engine makes use of a Honeywell single variable turbine turbo (similar to the one found on the Porsche 911 Turbo), but takes turbo technology a step further still. Instead of one, there are two compressor wheels driven off a single turbine impeller, working like a bi-turbo setup that gives the engine a fast response time with little lag as well as the power of a larger turbo.

Visually, the new engine looks remarkably different, due to the fact that the intake and exhaust systems are the reverse of a conventional engine. The exhaust manifolds sit in the valley of the big V8 engine, while the intake manifold is on the outside. This means the cylinder heads are essentially flipped around.

By significantly reducing the amount of exhaust piping, lag is reduced considerably. Additionally, this new packaging moves the hotter elements of the engine (like the turbocharger and exhaust pipes) away from the intake areas, ensuring a constant supply of cool air to the engine. And as for that turbo, it sits in the valley between the cylinder banks. Due to its location, spool up is considerably faster and the engine’s overall balance is improved. Another major benefit of this setup is that that cab no longer has to be removed from the frame if work needs to be done on the turbo. The fuel-pump, EGR (exhaust gas recirculation) components and the thermostats are also easily accessible from the front of the vehicle.

Ford still hasn’t released any info on how much power the new Super Duty makes, but we’ll be sure to report on it as soon as they do.
