The 428i GC’s test sheet reads like a replicate from the coupe’s. With similar gearing in addition to wearing exactly the same staggered 18-inch Bridgestone Potenza S001 run-flat all season tires, the GC raced the ¼-mile in 14.2 seconds on 98 mph, just a tenth of the 2nd and 1 mph behind this coupe. A 162-foot stop coming from 70 mph trim off two foot from a coupe’s performance. skidpan grip was exactly the same in 0.89 g.
This cars abuse no more change on the highway. When you had chosen the sport driving mode to be able to stiffen up a adaptive dampers as part of the $1000 Dynamic Handling package on our test auto, this GC shows the platform’s customary trait: a satisfyingly reliable control of body motions undermined by unexceptional steering experience.
The 3664-pound Gran Coupe weighs in at 135 lbs a lot more than the coupe, adequate to be able to drop the EPA highway score from thirty-five mpg to thirty-four for the GC. All of us saw twenty seven combined.
