This 428i GC’s test out sheet says just like a replicate from the coupe’s. Together with the same gearing and also using the same staggered 18-inch Bridgestone Potenza S001 run-flat summer tires, the GC running the ¼-mile within 14.2 seconds at 98 Miles per hour, just a 10th of a 2nd and one mph behind this coupe. A 162-feet end from 70 MiH trims 2 ft from a coupe’s high-performance . Skidpad grip had been exactly the same in 0.89 g.
The cars abuse no longer divergence on the road. Once you have selected the sport driving mode to stiffen up the adaptive dampers included in the $1000 Dynamic Handling package upon our test auto, the GC demonstrates the platform’s customary quality: a satisfyingly reliable control from body movements undermined by unexceptional steering experience.
The 3664-pound Gran Coupe weighs in at 135 lbs greater than the coupe, adequate to lower the EPA highway score from 35 mpg to thirty-four for the GC. Many of us found 27 combined.
