Why? Because this Cruze-sized GM prototype has been spotted undergoing cold-weather testing, and there are more than a few key differences between it and the Chinese-market version.
The overall silhouette is similar, but the prototype's dual-port front grille appears less dominant than the Chinese model, while the wing mirrors are mounted to the door skins rather than nested in the corner of the window frame.
But most telling are the more prominent curves in the side sheetmetal.
This prototype shows heavier contouring than the Chinese-market Cruze, and the fact that General Motors has covered the whole car in camouflage indicates there's more than just a nose job here
As for what resides underneath, odds are it will be the same FWD architecture as the Chinese Chevrolet Cruze.
It's still too early for news about engines to surface, but you can certainly put your money on a 1.4 litre turbo alongside larger-capacity naturally-aspirated petrol engines.
A diesel will likely continue to form part of the range, and GM's seven-speed twin-clutch auto (already offered in the Chinese-market Cruze) is a virtual certainty for the international market.
