Astra J VXR

The Astra J GTC VXR is powered by a GM developed 2.0 turbocharged direct injected engine. Originally developed for the American market, the current development of this 2.0 engine is a higher power unit, known in Europe as A20NFT (LHU).

This engine, in standard guise, develops 280PS (276bhp) and 295 lb ft torque, featuring an all alluminium block and cylinder head; the latter being unique to the Astra VXR. Specification wise the 2.0 engine is a 1998cc 16v (4 valves per cylinder) engine, with a 9.3:1 compression ratio, has an 86mm bore and stroke with Variable Valve Timing, under-piston cooling and a twin-scroll turbocharger.

Our Testing - Standard Power:
When testing standard factory cars which are quoted at 276bhp we have seen power outputs as low as 265bhp through to 285bhp. This variation can carry through when modified and subsequently we have seen some low power cars improve (aside from the usual climatic conditions) as the mileage climbs and the car loosens up. This is why we show a broader range of expected power than perhaps we have seen previously with other VXR models. Our power figures quoted have been achieved with the same car, always using Shell V- Power
