Our 428i GC’s test out sheet reads just like a replicate from the coupe’s. Together with similar gearing and putting on the same staggered 18-inch Bridgestone Potenza S001 run-flat all season tires, this GC to run the 1/4-mile in fourteen point two seconds in 98 MiH, merely a 10th of a 2nd and 1 Miles per hour behind the coupe. A 162-foot stop coming from seventy Miles per hour trim down two foot from a coupe’s high performance. skidpan grip has been exactly the same at 0.89 g.
The cars betray no more divergence on the road. Once you have chosen a sport driving mode to stiffen up the adaptive dampers included in the $1000 Dynamic Handling package on our test auto, the GC displays the platform’s customary quality: the satisfyingly reliable control of body moves undermined by unexceptional steering experience.
The 3664-pound Gran Coupe weighs in at 135 lbm greater than a coupe, sufficient in order to lower the EPA highway rating from thirty five mile per gallon to thirty four for the GC. Most of us discovered twenty seven combined.
