The Astra OPC has familiar styling but is distinguished by a revised rear bumper with an integrated diffuser.

Opel just unveiled the Astra GTC in Frankfurt, but work continues on the high performance OPC.

Seen here testing with minimal camouflage, the model has familiar styling but is distinguished by a revised rear bumper with an integrated diffuser and a dual exhaust system. There are also Brembo brakes and what appear to be 20-inch alloy wheels.

Under the hood, we can expect a turbocharged 2.0-liter four-cylinder engine with approximately 300 PS (220 kW / 295 hp). It will be paired to a six-speed manual transmission which will send power to the front-wheels via a limited slip differential.
