The company says that both models will feature Vauxhall’s advanced plug-in hybrid powertrains and offer the optimum balance between ride comfort and performance-oriented handling, as well as ultra-low emissions.
James Taylor, acting managing director of Vauxhall, said: “Available with plug-in hybrid powertrains from launch, the all-new Astra GSe and all-new Astra Sports Tourer GSe are the ideal cars for launching our dynamic new sub-brand, offering sporty styling, enhanced driving performance and all the benefits of an electrified powertrain.
“As we work towards becoming an all-electric brand by 2028, our range-topping GSe models will showcase that electrified performance and driving pleasure can go hand-in-hand.”
GSe stands for Grand Sport Electric and offers sporty looks that build on Vauxhall’s new design philosophy, as well as driver-focused chassis set-ups that complement the higher performance of an electrified powertrain whilst retaining zero-emissions.
With a power output of 222bhp, maximum torque of 266lb ft, and fuel economy of up to 256.8mpg, the Astra GSe and its Sports Tourer counterpart will match the best in their respective classes for launch from a standstill, acceleration, and maximum speed.
Vauxhall has achieved the performance-oriented handling characteristics by equipping the new Astra GSe models with a dedicated chassis that is 10mm lower than before, which it says delivers superior stability during cornering, under braking and at higher speed.
A special GSe suspension set-up and steering calibration offers more agile and precise handling characteristics.
The cars’ ESP settings are also tuned to GSe models, with a higher activation threshold to match their dynamic driving behaviour.
Further specification details including prices will be announced later and Vauxhall says the vehicles will go on sale in the UK towards the end of the year with first deliveries scheduled for early 2023.
