Vauxhall's new Astra VXR will incorporate deliver a class-leading 400Nm of torque, giving it a 0-60mph time of 5.9 seconds and robust mid-range performance. The VXR's turbocharged, 2.0-litre direct-injection engine harks from the Insignia family, but while its aluminium block is similar, the VXR has a unique aluminium cylinder head and new turbocharger to liberate 280PS (up 40PS on the previous model) and over 200Nm per litre of torque - the highest specific output in its class. Developing a high-torque engine for the Vauxhall Astra VXR was the key to unlocking the car's real-world, mid-range performance, rather than focusing on power alone. And with maximum torque produced on a broad plateau between 2450rpm and 5000rpm, VXR drivers will never want for instant acceleration. An all-new, state-of-the-art intake system was developed to feed as much air into the turbocharger as possible. The turbocharger itself was also improved to take more charge-air pressure, which builds from as early as 1400rpm for linear and strong acceleration. The maximum charge pressure is now 1.5 bar - 25 per cent more than in the Insignia 2.0T.
