In the latest installment of Dodge’s teaser campaign for its 2018 Challenger SRT Demon, the American muscle car brand revealed a new Air Grabber hood scoop. The scoop is the biggest fitted to a production car and helps boost the power of the Demon’s supercharged 6.2-liter V-8.

Chevrolet has released a teaser for a new GT4-spec race car based on the Camaro. It replaces the successful Camaro Z/28.R racer based on the fifth-gen car and has been designed for global GT4 competition.

Just as the inaugural season of “The Grand Tour” comes to a close, a new season of “Top Gear” is warming up. The good news is that Chris Evans is out. He’s been replaced by the much more enjoyable Chris Harris.
