The new small BMW has a revised roofline and A-pillar shape compared with the prototype vehicle we've seen testing in the past; not too surprising a revision as the vehicle transitions to something closer to its production form. These images also mark the first time that our spies in the field have observed twin exhaust pipes on the car, which may indicate that this is a higher-performance version of the 1 GT.
Expectation is that the powertrain lineup for this car, which shares underpinnings with the next-generation of Mini, too, will be quite varied. Three- and four-cylinder engines are expected, most likely in 1.5-liter and 2.0-liter forms, along with a hybrid powertrain, too. Expect to see the car in both front-wheel and all-wheel-drive flavors sometime after its debut by the summer of 2013.
