Compared with its predecessor, the new Opel Corsa is a useful 108kg lighter. This is a weight-saving of around 10 per cent, although the new model has a similar length of 4.06 metres.
Whether diesel, petrol or – for the first time – electrically powered, every new Corsa benefits from the lower weight: the driving dynamics improve, the fuel consumption falls. The lightest version of the next generation even undercuts the magical 1,000-kilogramme mark – excluding driver, the five-door will weigh only 980kg. Reducing so much weight while retaining similar dimensions is a remarkable development achievement that directly benefits the customer. The Corsa will celebrate its premiere before the end of this year.
Intelligent lightweight design begins on the computer, using the newest virtual development methods. The specific use of various steel grades and connection methods enabled the Corsa’s big weight reduction. This includes the consistent use of high-strength and ultra-high-strength steels, as well as the optimization of load paths, connections, structure and form. Compared with the previous model, the body-in-white is 40kg lighter. The next Corsa is based on the new multi-energy platform for small and compact cars, which allows a variety of propulsion systems.
The extra-light, all-aluminium engines, together with optimization of the front and rear axles, also contribute to the low total weight. The particularly compact three-cylinder petrol engines weigh around 15kg less than the previous generation of similarly powerful four-cylinder units.
Highly unusual in the small-car-sector is the new Corsa’s aluminium engine bonnet, which although longer, saves 2.4kg in comparison to the previous model’s bonnet made of steel. The Insignia flagship was previously the only model in the Opel range with an aluminium bonnet.
The seats also have been put on a diet. The new optimized seat structure saves a total of 10kg – 5.5 kg at the front, 4.5kg at the rear.
Lightweight design strategically important at Opel
Depending on powertrain and equipment, the current models weigh up to 200 kilograms less than their predecessors.
