Gemballa GT Concept

The Gemballa GT Concept is a Porsche 911 turbo with a twist. Lots and lots of boost crammed into the car’s 3.8-liter inline six. Enough to push out an incredible 828 horsepower and allow a top speed of 224 mph.

The GT Concept has a carbon-fibre widebody kit to leave room for enough rubber to put some of that power down to the pavement.

Roush Mustang 729

Ford modifier Roush Performance has built some amazing Mustangs over the years. This might be one of the real greats.

The Mustang 729 gets a widebody kit with a carbon front splitter and rear diffuser. The wheels are from Vossen, and the suspension is a Roush three-way adjustable coilover suspension system. The 729 in the name comes from the power level. The supercharged 5.0-liter V8 makes 729 horsepower.
