Hybrid technology?
http://www.iht.com/articles/509400.html
Ford now licensing from Toyota instead Honda for Escape hybrid system (see article above). Can it be supersized to go into an F150 eventually? The F150 already weighs a ton (actually several) so the extra battery weight might not be a big deal and electric motors are all about torque - even at 0 RPM.
What do you Ford powertrain guys think? Cost prohibitive?
...or alternatively is this Bill Ford's answer to the Pinnochio ads?

Very funny!
Electrics actually drive trains, the diesel engines create electricity that drives the wheels - you want true pulling power, put an electric at all four wheels. Of course there are issues with acceleration...look at the torque numbers for the tiny electric in the Prius, and it is all available at 0 RPM.
I would agree clean diesel is a great alternative (as a single engine) especially the new direct rail injection type engines that avoid the turbo coking problems, but still give the boost of a turbodiesel. Jeep will offer a nice 4 cylinder version in the Liberty - with something like 25+ MPG - and 7700 lb towing capacity. Not bad for wimpy sport-ute.

Have you test driven the 2004 Prius? I think you would be surprised at how fast it really does accelerate. I have test driven one. You notice the loss of vision compared to the F150.
Waiting for hybrids to come to the larger cars/SUVs.

I don't want to sound pedantic but I don't think you can produce torque at 0 RPM.
You have to be turning to exert torque.
Apart from that, don't hold your breath till there is proper fuel cell technology.
Nice idea though.

Well actually on an electric motor you can have torque at 0 rpm, it is known as stall torque or locked rotor torque. Many of our electric motors we do test for stall torque or locked rotor torque to insure they meet specifications.
Torque in an electric motor is usually greatest at stall (torque load applied until shaft movement is stopped), it is basically a liner type of curve starting at 0 torque at no-load and building as you apply a load. This is for DC motor's...
