Saleen is back with a new standalone sports car called the S1. The mid-engine marvel packs a 450-horsepower 4-cylinder and weighs just 2,685 pounds thanks to aluminum and carbon fiber construction.

Another American firm, Aria Group, has unveiled a hybrid supercar with 1,150 horsepower. Right now it’s just a concept but production of 400 examples is planned.

Aston Martin’s new Vantage has been revealed to the public. It has 503 hp from a twin-turbo V-8.
