It's well known Cadillac's presidential limo is based on the platform of a pickup truck. Now, a vehicle customizer from Italy has launched its own sedan based on a pickup truck's platform, in this case the platform of a Ram 1500. The resulting sedan measures almost 20 feet in length and is powered by a twin-turbocharged V-8.

Porsche has teamed up with Brazil's Embraer to develop a special 911 Turbo S inspired by one of Embraer's private jets. Just 10 examples of the special 911 will be built, and if you want to own one you'll first need to buy a matching Embraer Phenom 300E jet.

Ram has just launched the 1500 TRX powered by the Hellcat 6.2-liter supercharged V-8. But how does it stack up against the Ford F-150 Raptor? Find out in our comparison review.
