Building on the compact X3
's platform, the X4 is labeled a coupe for its sleeker roofline. Rear-seat occupants get less space here, but adults still fit. There's also plenty of typical-for-BMW performance on offer thanks to available power that rivals what the M3
boasted not that long ago. It may be polarizing, but there's no arguing against how much style the X4 contributes to the crossover class.
