The BMW 5-Series GT never caught on in the U.S. market, where it was originally envisioned to replace the more conventional 5-Series wagon. Aside from its innovative two-piece liftgate, the 5 GT had somewhat awkward styling that had neither the ruggedness of an SUV nor the sleekness of a 5-door fastback. But based on these spyshots of the upcoming 3-Series GT, little brother could potentially find itself a lot more friends. Also snapped on the 'Ring were an updated X5 M.
Other details noted by our spy shooter are cross-drilled front brake rotors on the X5 M, and a new headlight design connecting the headlamp clusters with the grille, similar to the new F30 3-Series. As with the current BMW X5 M, the front end features generously-sized air intakes to cool off the monstrous S63B44Tü 560 hp twin-turbo V-8 from the F10 M5. Although the new engine only has 5 more horsepower than the current engine, the higher compression ratio and Valvetronic valvetrain actuation promise increased fuel economy.
The styling of the 3-Series GT is considerably sleeker than that of its larger 5-series counterpart, offering yet another crossover/SUV variant in the BMW lineup, which now includes the BMW X1, X3, X5, and X6. Later in 2013, the wagon version of the new 328i will make an appearance stateside as well, but will be the only configuration offered initially in North America. Powertrains for the 3-Series GT could be the 2.0-liter, 240-hp TwinPower four-cylinder turbo from the 328i, and the 3.0-liter, 300-hp turbocharged I-6 from the 335i.
