Two Sedans with some similarities, but otherwise different in most aspects such as the model year, powertrain, starting price, fuel economy, market segment, horsepower, height, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2013 BMW 7 Series, which is $22,500 less than the base MSRP of the 2016 Porsche Panamera Hybrid, which is three model years newer. Also, the 2013 7 Series has a more powerful engine and gets 6.4 mpg less than the 2016 Panamera Hybrid. In addition, the roofline of the 7 Series is slightly higher than the Panamera Hybrid's. And then, you'll seat one more passenger in the BMW 7 Series than in the Porsche Panamera Hybrid. Among similarities are the body structure, market segment, and ground shadow size.
