The most powerful production Opel Astra ever has made its world debut during the 84th Geneva Motor Show. The Astra OPC EXTREME was unveiled a week ago and now had its first public appearance in Switzerland.

The car is based on the standard OPC, but is 100 kg (220 lbs) lighter thanks to the use of carbon fiber on some body aero panels and on the wheels. The lightweight material is placed on the hood, on the front diffuser, bumper and spoiler, and on the roof.

Opel has mounted under the hood a 4-cylinder, 2.0-liter turbocharged engine that produces 300 bhp (224 kW). It is mated to a six-speed manual transmission and a limited slip differential, sending power to the front wheels. The fastest Astra ever has a Brembo six-piston brake system with 370mm front discs sitting behind the 19-inch alloy wheels wrapped around in specially developed 245/35 tires.

Still no performance specifications have been provided, but the car is certainly faster than the regular Astra OPC, which needs 5.9 seconds until 60 mph (96 km/h) on its way to a top speed of 155 mph (250 km/h).

No pricing details have been announced yet, but Opel promised the Astra OPC EXTREME will enter low-volume production in the coming months.
