The 428i GC’s test sheet says like a duplicate of a coupe’s. Together with the same gearing along with wearing a similar staggered 18-inch Bridgestone Potenza S001 run-flat all season tires, this GC run the quarter-mile within 14.2 seconds in 98 MiH, just a tenth of the 2nd and one MiH behind this coupe. A 162-feet stop from 70 mph trim off two ft from the coupe’s performance. skidpan grip had been the same at 0.89 g.
This cars abuse not anymore change on the road. When you have selected a sport driving mode in order to stiffen up a adaptive dampers as part of the $1000 Dynamic Handling package deal upon our test car, this GC shows the platform’s customary characteristic: a satisfyingly strong control from entire body motions undermined by unexceptional steering sense.
This 3664-pound Gran Coupe weighs 135 lbm more than the coupe, adequate to be able to lower the EPA highway rating from thirty five mile/gallon to 34 for the GC. We noticed twenty seven combined.
