Our 428i GC’s test sheet reads as well as duplicate of a coupe’s. Along with identical gearing along with using exactly the same staggered 18-inch Bridgestone Potenza S001 run-flat summer tires, the GC raced the quarter-mile within fourteen point two seconds on 98 mph, just a tenth of the 2nd and one MiH behind the coupe. A 162-foot stop coming from seventy Miles per hour trim off two foot from the coupe’s high performance. Skidpad grip has been the same at 0.89 g.
The cars abuse no longer difference on the road. When you’ve selected a sport driving mode to stiffen up the adaptive dampers contained in the $1000 Dynamic Handling package deal in our test vehicle, the GC shows the platform’s customary attribute: the satisfyingly solid control from body motions undermined by unexceptional steering experience.
The 3664-pound Gran Coupe weighs 135 pounds more than the coupe, sufficient in order to lower the EPA highway score from thirty five mile per gallon to thirty-four for the GC. We noticed twenty seven combined.
