Two Coupes with some similarities, but otherwise different in most aspects such as the ground shadow size, market segment, starting price, horsepower, height, and maximum occupancy. First of all, there is a $29,525 difference in the base MSRP. The 2016 Maserati GranTurismo has a higher starting price than the 2016 Aston Martin V8 Vantage Coupe. Also, the 2016 V8 Vantage Coupe produces fewer horsepower than the 2016 GranTurismo. In addition, the V8 Vantage Coupe is both significantly smaller and slightly shorter than the GranTurismo. And then, you'll seat two more passengers in the Maserati GranTurismo than in the Aston Martin V8 Vantage Coupe. Among similarities are the body structure, market segment, and fuel economy.
