Vauxhall has given the Astra five-door and Sport Tourer versions the same powerful and flexible engine as the Bi Turbo Astra GTC.
The twin-turbocharged 2.0-litre diesel engine features a small turbine for low-speed response and a bigger turbine for additional power at higher engine speeds. This means there is 192bhp and 295lb.ft of torque with 236 lb.ft on offer from only 1,250rpm.
As a result, both models are able to drive 135mph and do 0-60 in less than eight seconds, while also managing more than 55mpg and only emitting 134g/km of CO2.
As well as the new improvements to the entire Astra range, BiTurbo Vauxhall cars will also boast 18-inch alloy wheels, twin rear exhausts, an outside styling pack and alloy sports pedals.
People considering car finance options may be interested to hear about the pricing of the new models.
Prices start at £24,095 for the Astra five-door and £25,110 for the Sport Tourer.
