This 428i GC’s test sheet states as well as replicate from the coupe’s. Along with similar gearing and also wearing the same staggered 18-inch Bridgestone Potenza S001 run-flat summer tires, this GC run the ¼-mile in 14.2 seconds on 98 MiH, merely a tenth of a 2nd and 1 mph behind this coupe. A 162-feet end from 70 MiH trim away 2 ft from a coupe’s performance. Skidpad grip had been exactly the same in 0.89 g.
The cars abuse not anymore change on the highway. Once you had selected a sport driving mode to be able to stiffen up the adaptive dampers included in the $1000 Dynamic Handling package deal on our test vehicle, this GC demonstrates the platform’s customary attribute: the satisfyingly reliable control from entire body motions undermined by unexceptional steering feel.
The 3664-pound Gran Coupe weighs 135 pounds more than a coupe, adequate to decrease the EPA highway rating from 35 mpg to 34 for the GC. All of us saw twenty seven combined.
