Opel and Vauxhall are putting the finishing touches on the 2020 Corsa, ahead of its launch this fall.

As part of the effort, engineers have been testing prototypes in Sweden since January. Opel describes the tests as “intensive” and noted they took place in “ultra-low temperatures on frozen lakes and snow-covered roads.”

In particular, Opel’s chassis development team has been fine-tuning the stability, traction and anti-lock braking systems. Doing this in the Arctic Circle is ideal as the snowy and icy conditions provide plenty of low-grip surfaces to work with.

The long polar nights also enabled engineers to test the Corsa’s new Adaptive IntelliLux LED headlights. Similar to the ones found on the Astra and Insignia, the high-tech headlights provide optimum visibility without blinding oncoming vehicles.

While cold weather testing is important, those aren’t the only tests that have been taking place. Pre-production models have been lapping oval courses, handling circuits and the comfort track at the Dudenhofen Test Center. Some of the tests focused on fine-tuning the car’s speed-sensitive steering system which promises to provide “optimum precision” and good feedback.

The tests also focused on comfort and handling as Opel noted the shock absorbers have been designed to immediately react to even the slightest changes in the road surface. As Opel’s global lead development engineer for vehicle performance, Thomas Wanke, explained “Every Opel must deliver a firm, precise ride over undulating surfaces at autobahn speeds.”

The model has also undergone extensive electro-magnetic compatibility tests in Russelsheim, Germany. These focused on ensuring the Corsa’s various systems – including everything from the infotainment system to safety features – aren’t affected by electro-magnetic emissions.

Opel and Vauxhall didn’t say much about specifications, but they confirmed the redesigned model will be ten percent lighter than its predecessor and available with an electric powertrain. The companies are particularly happy about the weight reduction as Wanke noted it not only lowers fuel consumption, but also ups the fun factor. Speaking of the latter, the 2020 Corsa promises to be “perceptibly more dynamic than its predecessor.”
