The Cadillac of hot rods

Take a large displacement, high powered engine, and drop that puppy under the hood of a stripped down chassis. That's the hot rod formula. That's also what makes the Cadillac VSR concept so interesting to a gearhead like me.

Open wheel thrills

All four of the VSR's corners are independently suspended with air suspension. Up front, a pair of 20-inch wheels is connected to an electronic power steering system.

Four wheel disc brakes

Look carefully and you'll see cooling ducts on the backside of the wheels that divert air over the 13-inch, six-piston disc brakes.

Single seat configuration

The VSR was displayed in a single-seat configuration, but the passenger-side tonneau cover can be removed to reveal a second seat.

Cabin technology

Behind the scissor doors, you'll find a pair of carbon fiber bucket seats and a digital instrument cluster. An iPhone compatible audio system and rearview camera round out the admittedly limited cabin tech package.

Heat shielding

GM really had to cram the V-8 into the narrow engine compartment along with the radiator, so gold foil heat shielding is used to protect the air suspension components.
