Two Sedans with some similarities, but otherwise different in most aspects such as the starting price, horsepower, fuel economy, and height. First of all, there is a notable difference in the starting price of the 2016 Maserati Ghibli, which is $8,900 less than the base MSRP of the 2016 BMW 6 Series Gran Coupe. Also, the 2016 6 Series Gran Coupe has a more powerful engine than the 2016 Ghibli, but it gets 1.3 more miles on a gallon of fuel. And finally, the roofline of the 6 Series Gran Coupe is slightly lower than the Ghibli's. Among similarities are the body structure, market segment, ground shadow size, and maximum occupancy.
