Because of the size of the segment, we restricted it to segment bestsellers and staples, the Honda Accord and Toyota Camry, as well as the bestsellers from American and South Korean companies, the Ford Fusion and the Hyundai Sonata. As always, these are simply comparisons of specifications and statistics, and for additional nuances, be sure to check out our in-depth reviews on these cars. And if you’d like to compare any or all of these cars with other vehicles in the segments, be sure to try out our car comparison tool. Now, onto the numbers.
Engines, transmissions and performance
With the exception of the Toyota Camry, every high-horsepower family sedan here relies on turbocharged four-cylinder power. And of those turbo four-cylinders, only the Mazda displaces 2.5 liters while the rest make do with 2 liters. There are clear horsepower and torque winners, too. The Camry’s 301 horsepower eclipses the rest of the segment by roughly 50 horsepower, and the Mazda6’s 310 pound-feet of torque out-twists the next-most-torquey Ford Fusion by 35 pound-feet. Only one car in this group is available with a manual transmission, though, and that’s the Honda Accord. The Ford also has an ace in the form of optional all-wheel-drive. Fuel economy is an incredibly tight race, with all but the Fusion managing 26 mpg combined. The Mazda6 and Hyundai Sonata win in the city with 23 mpg, and the Camry’s 33 mpg on the highway wins that category. The Ford Fusion is worse in every fuel economy category.
Interior and exterior dimensions
Before digging into the size of these vehicles, we need to point out that the dimensions for the Mazda6 are estimates using the 2017.5 model, since exact specs for dimensions are unavailable for the 2018 model at the time of publishing. Considering the fact that the 2018 update that introduced the turbo engine is a mild refresh consisting mostly of updated fascias, restyled dashboard, and more insulation, we don’t think the dimensions will change much. Also of note is the curb weight of the Mazda and the Ford Fusion. With the Mazda, we expect the turbocharged model will be heavier than the naturally aspirated 2017.5. With the Ford, the company only lists weight for the 2.5-liter naturally aspirated engine. We suspect the turbocharged engine weighs more.
With that out of the way, it’s surprising how close these cars are in size. Length-wise these sedans are within an inch or so of each other, with the shortest being the Hyundai Sonata, and the longest being the Honda Accord. The Camry and Mazda6 are tied for narrowest, and the Ford Fusion is the widest. The Accord and Mazda6 are the lowest, and the Ford is the tallest.
Inside, the Hyundai Sonata has the most spacious front seat accommodations, with the most head, leg and shoulder room of the bunch. The Ford Fusion is a very close second. The Mazda6 is the tightest up front, closely followed by the Camry. In the back, there isn’t one clear winner. The Accord has the most legroom, while the Sonata has the least. The Fusion has the most shoulder room; the Mazda6 has the least. And the Sonata has the most head room and the Mazda6 has the least. Cargo space is much more clear cut. The Honda Accord’s 16.7 cubic feet easily wins for most room, and again the Mazda6 falls behind with 14.8 cubic feet.
In the all-important realm of price, the Ford and the Hyundai are the clear winners. The Fusion is the cheapest with a base price just over $27,000, and the Hyundai is close behind with a base price just over $28,000. Adding all-wheel-drive to the Fusion adds $2,000, but that would still keep it one of the cheapest in this group. The Mazda and Honda are very close between $30,000 and $31,000. The Camry is a pricey prospect at a whopping $35,000 and change. That’s about $8,000 more than the cheapest Fusion in this group.
