Vauxhall Astra BiTurbo now generates 195 horsepower
Vauxhall Astra BiTurbo five-door Hatch and Vauxhall Astra BiTurbo Sports Tourer are the new two high performance diesels from the brand. Both are generating 195 horsepower (143 kW) and have 400 Nm (295 lb-ft) of torque.
Both Vauxhalls are the most powerful cars in their class: they offer blistering performance, high levels of practicality and impressive frugality. Their top speed reaches 135mph and can achieve 0-60mph in less than eight seconds.
Despite the boost in performance, they have excellent economy as well: low CO2 emissions of 134g/km and a combined efficiency of 55.4mpg. The great fuel economy is further enhanced by the Start/Stop technology included in the models.
In fact, the twin turbo technology is rare in this class. The Astra uses a sequential turbocharging system, with the smaller turbo accelerating quickly at lower speeds to eliminate ‘lag', providing 320Nm (236 lb-ft) of torque from 1,250rpm.
Furthermore, in the mid-range of rpm, both turbochargers operate together, with the larger turbocharger pre-compressing the intake air, before it is fully compressed in the smaller one. A continuous control over the bypass valve is happening, in order to pass on part of the exhaust gases to the larger turbo. The effect of all this is that the driver still enjoys smooth acceleration.
In addition, some stylish changes have been made as well. The new Astra now has more aggressive look thanks to the revised front grille, new front indicators and fog lamps, and refreshed rear-panel styling.
Other unique features are the fresh 18" alloy wheels, twin rear exhausts, exterior styling pack and alloy sports pedals.
The Vauxhall Astra BiTurbo five-door Hatch has a starting price of £24,095 and the Sports Tourer - £25,110.
