Start with a Vauxhall/Opel/Chevrolet/Saturn Astra VXR, shed 100 kg by replacing metal with carbon fiber, then pump its 2.0-liter turbo engine to 297 hp (221.5 kW), upgrade the suspension wheels, tires, gearbox and brakes to cope with the stresses, and you have the Astra VXR Extreme ... and it's street legal.

 

The Astra VXR Extreme has been derived from last year’s Astra Cup race car that competed in the Nürburgring Endurance Championship, with much of the knowledge gained in racing under such extreme conditions lavished on the aptly named Extreme.
