Hennessey

The veteran GM performance vehicle engineer and racer has a deep resume.

More powerful and growlier than the Ford GT.

An extra 150 horsepower to drive the luxe for $19,950.

First comes a 300-mph run, but he believes his coupe will 'go well beyond' that.

Silverado-based biblical beast boasts 705 hp from a supercharged V8.

If needed, more power may be added to hit 301-mph top speed.

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk.

Texas tuner John Hennessey wants to steer the 2018 Lincoln Navigator into some serious performance SUV territory, presently dominated by the Mercedes-Benz G-Class and Range Rover SVR. Upping the power of Lincoln's range-topping sport-utility, from 450 horsepower to an even 600 hp, is enough to hustle the Navigator from 0-60 mph in 4.8 seconds and run the quarter mile in 12.9 seconds at 107 mph.

It has a fancy steering wheel, too.

We're looking forward to hearing more about the engine.

For $1.6 million, a chance to be fastest.

And that's not even the 600-horsepower upgrade.

When you want Demon performance with a droptop.

It has been a long wait.
