Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when ...

But, to both our surprise and relief, the little-engine-that-could held its own quite honorably in yet another series of dyno floggings and cracked 500 lb-ft of torque in the process.

Most electric cars aren't normally associated with performance, but they are able to achieve something gasoline-powered cars can't: peak torque at zero rpm. It's thrown around often, and many will ...

That also means you'll likely prefer a diesel engine. Compared to their gasoline-swilling counterparts, diesel engines are the torque kings. Why is that?

Cummins has put together an upgraded version of its 6.7-liter engine turbo diesel for RAM trucks - here's how much power this new powerplant can produce.
