New 2019 Vauxhall Corsa supermini set for a crash diet

The new Vauxhall Corsa will be around 100kg lighter than the outgoing model, thanks to a redesigned body shell and aluminium engines

Vauxhall has released some preliminary figures for the upcoming Corsa’s kerb weight, along with a sketch of its bare frame. The firm claims a ten per cent reduction in weight over the previous model thanks to a redesigned body shell and lighter, aluminium engines. The lightest variant will squeeze under the one-tonne mark, weighing just 980kg.

The new Vauxhall Corsa’s body will be constructed from a range of high-strength steels, stitched together in the most weight-conscious manner, saving a total of 40kg over the outgoing model. A new aluminium bonnet will also replace the previous Corsa’s steel unit, saving a further 2.4kg.

Under the bonnet, Vauxhall’s latest range of aluminium three-cylinder petrol and diesel engines save around 15kg over the old Corsa’s four-cylinder units. Inside, Vauxhall has also managed to shave a total of 10kg off the seats, losing 5.5kg at the front and 4.5kg at the rear. In total, the firm claims a total weight saving of 108kg.

Despite the weight-loss, the upcoming Corsa will be slightly larger than its predecessor, with its bigger body and longer wheelbase unlocking more interior and boot space. Our most recently-spied mule is also further evidence that Vauxhall will ditch the Corsa’s three-door body style, as the only prototypes spied thus far have been practical five-door models.

Due to Vauxhall’s recent acquisition by the PSA Group, the new Corsa will be built on Peugeot-Citroen’s latest Common Modular Platform (CMP). The underpinnings are shared with the new Peugeot 208, so it’s reasonable to suggest that the Corsa’s weight savings have also been applied to the French firm’s new supermini.

Vauxhall claims these revisions will improve both the Corsa’s performance and efficiency, with the firm promising better acceleration and reduced fuel consumption and CO2 emissions. Vauxhall has also confirmed that an all-electric version of the new Corsa will eventually feature in the range, alongside its range of conventionally-powered cousins.

The new Corsa’s engine range will consist exclusively of PSA units, shared with the new 208. A new generation of the BlueHDi diesel is being developed, which will downsize from a 1.6 to a 1.5-litre capacity, offering power outputs ranging from around 75bhp to 120bhp, with CO2 emissions as low as 75g/km. However, it’s unknown if it will be offered in the UK.

PSA’s PureTech petrol engine will also get a refresh, with the three-cylinder 1.2-litre turbos offering improved performance and efficiency. A more potent 1.6-litre turbo will also be made available to Vauxhall if it chooses to develop a Corsa VXR hot hatch.

While the vast majority of the running gear will be shared by the 208 and Corsa, Vauxhall will have its own say in terms of interior and exterior design. One of Vauxhall’s planned features is a set of glare-free LED Matrix headlights. The lighting technology is usually reserved for premium manufacturers and works by automatically adapting to the traffic ahead, “cutting out” oncoming cars from its beam. The system supposedly maintains visibility for the driver and reduces glare for other motorists.

Finite details of the new Corsa’s styling are difficult to identify, as the masking does a good job of hiding its features. However, we can tell it will adopt a less boxy appearance than our exclusive render, with a curvier nose and a more sharply-tapering tail. A larger rear wing and a wider bumper intake also feature.
