Vauxhall has revealed the first pictures of the brand-new Astra, with the refreshed model getting a 200 kg weight cut as well as new engines and transmissions.
Development in the wind tunnel is said to have made a “significant” contribution to reductions in fuel consumption and CO2 emissions – the latter cut by up to 19 per cent.
At 0.26 Cd, Vauxhall claims the Astra is now “the most aerodynamic car in its five-door hatch back class”. And at 0.25 Cd, the estate version, the Astra Sports Tourer, is designated “among the best-in-class”.
Company designers say the aero-benchmarks have been achieved through a number of measures, including an engine compartment cover, deflector-shaped rear axle control arms and a full-face shutter. The upper and lower portions of the new Astra’s radiator grille automatically open and close independently of one another, further improving the frontal airflow. Additionally, underbody revisions are said to have improved the drag coefficient by reducing turbulence.
The Astra’s chassis has been further developed with new shock absorbers that are claimed to increase comfort.
Under the bonnet, there are a range of new engines, starting with a three-cylinder, turbo petrol unit that comes in 1.2 and 1.4-litre displacements, with power outputs extending from 108 bhp to 143 bhp and maximum torque from 144 lb-ft to 174 lb-ft.
While the 1.2 is combined with a six-speed manual gearbox, the 1.4 is available exclusively with a new seven-speed CVT transmission.
The Astra’s 1.5-litre, three-cylinder diesel engines, meanwhile, offer 104 bhp and 120 bhp, as well as 192 to 221 lb-ft of torque.
And instead of the six-speed manual gearbox, the most powerful diesel is optionally available with a new nine-speed automatic transmission, which is making its debut at Vauxhall in the Astra.
The new Astra will go on sale in the UK starting from next month.
