Following the success of Vauxhall's BiTurbo Astra GTC, the manufacturer has put the engine in its Astra five-door and Sport Tourer models.
The twin-turbocharged 2.0-litre diesel offers a combination of power, economy and greenness as both models are capable of over 135mph and 0-62mph in less than eight seconds and give over 55mpg with CO2 emissions of only 134g/km.
The engine produces 192bhp and 295lb.ft of torque with 236lb.ft available from only 1,250rpm and can call on a small turbine for low-speed response and a bigger one for additional power at higher engine speeds.
All BiTurbo models also come with 18-inch alloy wheels, alloy sports pedals, twin rear exhausts and an exterior styling pack and, at £24,095 for the Astra five-door and £25,110 for the Sport Tourer, there may even be some change forbreakdown cover .
