The SUV's and crossover seem to adopted a tapering roof line per the Aero-Template, although there a few hold outs.
Yes.
One easy example is, Audi's E-Tron series. You can watch the progression of drag reduction ( Cd 0.28- Cd 0.26- Cd 0.22 ) as the roofline moves closer to the streamline pathway, from the 'raked-back', to 'Sportback, and finally 'Fastback', on the GT.
Chevy's Malibu MAXX suffered Cd 0.37 from it's mutilated Kamm-back, which dropped to Cd 0.301 when morphed to a notchback.
Current Malibu sedans are almost a true fastback, as CIVIC, Camry, Accord, Optima, Sonata, etc..
