Still too long, but my Panamera2 has lost its hunchback appearance. My family sport-saloon would pare down the surrounding body structure to an absolute minimum—and keep superfluous body sculpting to a minimum as well. Glass area is increased but weight would be decreased by 1,000 lbs for an average of 3,000 unladen pounds. Motivation would include a brand new four cylinder hybrid version good for 275 combined horsepower with 50 mile-per-gallon ratings and a 0-62 mph time of 5 seconds flat. Body would be carbon-fiber and aluminum.
