Rumor: Ford to power-up its 6.7-liter power stroke V8 diesel engine

Article by Christian Andrei, on August 29, 2010

Sources say that within the next year, it's likely that Ford will power-up its all-new 6.7-liter Power Stroke V-8 diesel engine. This action is said to be in response to GM's unveiling of best-in-class power ratings for its 6.6-liter Duramax V-8 diesel.

Last February, Ford revealed that the 6.7-liter Power Stroke V-8 for its 2011 Ford F-Series Super Duty will deliver 390hp and 735 pounds-feet of torque.

Not to be outdone, in early March, GM said that its 6.6-liter Duramax V-8 diesel for the 2011 Chevrolet Silverado and GMC Sierra HD pickups will generate 397 hp and 765 pounds-feet of torque.

Certainly, Ford won't allow for it to be relegated to second place. It should be noted that the 6.7-liter PSD is a design with plenty of headroom for higher power settings.

Meanwhile, the 6.6-liter Duramax is based on a legacy architecture that's right at the limit of its performance envelope. The rivalry in the heavy-duty segment are particularly intense since a truck that has more power will prove to be superior in towing and hauling and this matters a lot to the customers.

It is believed that the 6.7-liter V-8 will produce more than 400 hp and over 775 pounds-feet of torque. The challenge lies in striking the right balance between power increase and fuel economy and emissions regulations.

The 2011 Ford F-Series Super Duty will go on sale in April with the power ratings already announced. Early buyers don't need to worry that they're missing out if by next year a power increase is offered since an upgrade would only require a reflash of the software in the 6.7-liter's engine control unit.
