The new Vauxhall Astra will be up to 200kg (130kg on average) lighter than its predecessor.
The new Astra features powertrains including petrol and diesel units ranging from 100PS to 200PS.
A new lightweight four-cylinder, 1.4-litre (145PS) ECOTEC Direct Injection Turbo has an aluminium engine block weighing in at 10kg less than the cast-iron block of the current 1.4-litre Turbo.
There’s also a base-level 1.0 ECOTEC Direct Injection Turbo (105PS) petrol engine and a 1.6 CDTi ‘Whisper Diesel’ range with outputs starting from 110PS up to 160PS.
The new Astra is almost 5cm shorter than its predecessor and is also 2.6cm lower. The dimensions have an impact on aerodynamics and efficiency with the new Astra boasting a drag coefficient below 0.30.
The wheelbase may have been reduced by 2cm but the amount of space inside increased. In combination with newly-designed seats, the passengers in the rear can enjoy an additional 35mm legroom.
Making its debut in new Astra is the new generation IntelliLink infotainment system that is compatible with Android Auto and Apple CarPlay.
The new Astra will receive its world premiere at the Frankfurt Motor Show, 17-27 September 2015.
