Flared arches, a sporty bodykit and a cocked rear wheel are sure signs that this camouflaged Ford Puma prototype is the upcoming ST performance variant.
This is from AutoCar:
Official details of the model's drivetrain and chassis set-up are still yet to be confirmed, but images of the prototype raising a rear wheel under hard cornering show it will feature a stiffer suspension set-up in the same vein as the Fiesta ST. The big wheels appear to hide larger-diameter front brakes, too, while the Puma seems lower to the ground than the stock model.
