Two Sedans with some similarities, but otherwise different in most aspects such as the starting price, model year, horsepower, fuel economy, ground shadow size, and height. First of all, there is an $181,700 difference in the base MSRP. The 2014 Bentley Mulsanne, an older vehicle by two model years, has a higher starting price than the 2016 BMW M6 Gran Coupe. Also, the 2016 M6 Gran Coupe has a more powerful engine than the 2014 Mulsanne, but it gets 3 more miles on a gallon of fuel. And finally, not only Mulsanne is slightly larger, but it's also taller than the M6 Gran Coupe. Among similarities are the body structure, market segment, and maximum occupancy.
