Two Sedans, but completely different in all significant aspects: model year, starting price, horsepower, fuel economy, ground shadow size, height, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2013 Porsche Panamera, which is $24,050 less than the base MSRP of the 2016 Maserati Quattroporte, which is three model years newer. Also, a bigger engine usually means less mpg. But the 2013 Panamera has a more powerful engine and it gets 1.3 more mpg than the 2016 Quattroporte. In addition, not only Quattroporte is slightly larger, but it's also taller than the Panamera. And finally, the Maserati Quattroporte seats one more passenger than the Porsche Panamera. Among similarities are the body structure and market segment.
