This is an extensive, long term, review of the BMW 3 Series GT. For the purpose of this test, they used the 328i GT Bimmer, which comes with a 2.0-liter 4-cylinder engine that develops 245 hp and 350 Nm of torque. The BMW 328i GT is able to get from zero to 62 mph (100 km/h) in 6.1 seconds. Its top speed, as you can imagine, is limited to 155 mph (250 km/h).
