The 428i GC’s test out sheet states as good as duplicate of a coupe’s. Along with the same gearing along with putting on exactly the same staggered 18-inch Bridgestone Potenza S001 run-flat summer tires, this GC running the 1/4-mile within fourteen point two seconds in 98 Miles per hour, merely a tenth of a second and one MiH behind the coupe. A 162-feet end coming from seventy MiH trims 2 foot from the coupe’s performance. Skidpad grip was exactly the same at 0.89 g.
This cars betray no more difference on the road. When you had selected a sport driving mode to be able to stiffen up the adaptive dampers contained in the $1000 Dynamic Handling package on our test automobile, the GC shows the platform’s customary quality: a satisfyingly reliable control of entire body motions undermined by unexceptional steering sense.
This 3664-pound Gran Coupe weighs 135 ?) more than the coupe, sufficient in order to decrease the EPA highway score from 35 mile/gallon to 34 for the GC. We saw twenty-seven combined.
