What we have here are two Sedans from BMW with some differences, such as the starting price, horsepower, model year, fuel economy, and height. First of all, the 2014 BMW 7 Series is priced $48,200 lower compared to the base MSRP of the 2016 BMW ALPINA B6 Gran Coupe, which is newer by two model years. Also, the 2016 ALPINA B6 Gran Coupe has a more powerful engine than the 2014 7 Series, and it gets 1 fewer mile on a gallon of fuel. And finally, the roofline of the 7 Series is slightly higher than the ALPINA B6 Gran Coupe's. Among similarities are the body structure, market segment, ground shadow size, and maximum occupancy.
