Not too long ago, if you had a 3/4 or 1 ton pickup that made 600 ft-lbs from its diesel engine, it was a really big deal. No longer. In 2010, both Ford and GM heavy-duty trucks top 700 ft-lbs from their turbo diesel engines with Ford claiming 735 ft-lbs and GM recently upping its number to 765 ft-lbs. But in what has become perhaps a new performance war, Ford is set to up the ante once again, this time by tuning it’s 6.7-liter PowerStroke turbo diesel to deliver 400 horsepower and a whopping 800 ft-lbs of torque.

It’s been claimed that these numbers are possible with the current powertrain due to such engineering features as a graphite iron block employed on the 6.7-liter version of the PowerStroke, along with Ford’s beefy six-speed automatic transmission, which was designed from the outset to handle extreme torque loads. At this stage it’s too early to say exactly how the increase in power and torque will be achieved, but expect revised engine mapping to be a prime factor, along with some hardware upgrades. However, given industry lead times and because 2011 Super Duty trucks are already on sale, the more powerful diesel will likely become available late in the model year, much to the chagrin of those that have already purchased one of the 2011 model year trucks. As somebody once said, the best things often come to those who wait.

And given the tug of war going on between Ford and GM, it will be interesting to see how the General responds to this latest salvo.
