This prototype has been spotted while testing at the Nurburgring recently, though guessing what it really is might prove tricky. The Corsa Spor does come with large wheels and a visible rear exhaust, but a 1.6-liter turbo engine with 150 hp doesn't sound that interesting.
Instead, this could be a replacement for the 1.7-liter diesel model. Opel has announced a new 1.6 CDTI engine that produces 136 PS and 320 Newton meters.
In our opinion, Opel should be worried about its gearboxes, pixelated screens and lack of interior design impact before doing anything under the bonnet. Previous spyshots with this new Corsa prototype have shown that that the interior is heading in the right direction and you should definitely hold onto your money if you want a Corsa right now.
