[Video] Kia Stinger GT vs. the BMW 640i Gran Coupe

In an effort to show just how powerful the 2018 Stinger GT really is on the road, AMCI Testing compared the Stinger against its competitors in a series of performance tests that reviewed acceleration, cornering, the slalom, and a closed-course lap. One of the competitors is a BMW 640i Gran Coupe. There is this argument that they are not exactly competitors. The German car is considerably larger and heavier, not to mention nearly twice as expensive. Are they really competitors?
