The MDX Sport Hybrid comes standard with a 3.0-liter V6, a lithium-ion battery, and three electric motors. Power gets sent to all four wheels, since every version of the Sport Hybrid gets all-wheel drive (AWD). One motor works up front, helping the V6 send power to the front wheels. Out back, there’s a motor at each rear wheel, creating a gas-electric all-wheel-drive system. Together, they operate as Acura’s Super-Handling All-Wheel Drive and put out a net 321 horsepower and 289 lb-ft of torque. That’s a bump of 31 hp and 22 lb-ft over the conventionally powered model.
This system was inspired by the NSX hybrid supercar, and it allows each of the rear wheels to have a different level of power. Unlike other hybrids, which typically employ a continuously variable transmission, the MDX has an actual 7-speed dual-clutch transmission with paddle shifters.
Unfortunately, this is where Acura gets in its own way again. The MDX features an annoying proprietary shifter design. There is a button for Park, a pull-tab for Reverse, and a circular button for Drive. As we’ve discussed in other reviews of cars with unique shifter designs, there's a safety issue in moving away from the same shifter design that has been used for years. Like all automakers, Acura should quit screwing around and go back to a normal shifter.
The MDX Sport Hybrid also features a Dynamic Mode selector to choose different drive modes. This could also have been designed better. Currently, you have to press it once, and then press it again to cycle through Comfort, Normal, Sport, and Sport+ drive modes. It takes too many button presses to cycle through to the mode you want. A switch, toggle, or dial would all have worked better than this setup.
But hop behind the wheel and start driving and you might forgive the MDX for those control design quirks. The MDX has a sporty ride quality, even in Comfort mode. The steering has a great feel to it, and the vehicle corners very well. Its acceleration and performance are surprising, and not just for a hybrid. The MDX Sport Hybrid handles and accelerates on par with a BMW X5—seriously!
Fuel economy for the regular MDX is 19 mpg city, 27 highway, 22 combined for front-wheel drive models. All-wheel drive gas-powered versions return 18 mpg city, 26 highway, 21 combined. Fuel economy for the MDX Sport Hybrid is 26 mpg city, 27 highway, 27 combined. In our week of driving, we found fuel economy of 28.1 mpg, a bit higher than those EPA estimates.
