2026 Acura MDX vs 2026 Genesis GV80: Luxury SUV Practicality and Efficiency in Ontario
Two rows of premium materials and one strong V6 don't automatically add up to a smart family SUV. The details that matter most, day after day, come down to how much space a vehicle actually gives your passengers and how much fuel it burns getting them there. The 2026 Acura MDX and 2026 Genesis GV80 both compete for the same three-row luxury buyer, but a closer look at their published specifications shows real gaps in efficiency and cabin space.
This comparison lines up both models across their most comparable configurations, the MDX's four SH-AWD trims against the GV80's 2.5T Advanced AWD and 3.5T Prestige AWD. The numbers below come directly from each automaker's published specification sheets, covering fuel economy, passenger volume, and cargo capacity.

Fuel Efficiency and Powertrain
The MDX's fuel economy edge holds up trim for trim. In its combined rating, the MDX's three most-ordered trims, SH-AWD Tech, A-Spec, and Platinum Elite A-Spec, post 11.2 L/100 km, edging out the GV80 2.5T Advanced AWD's 11.3 L/100 km. Move up to the performance-oriented trims and the gap grows: the MDX Type S Ultra returns 12.4 L/100 km against the GV80 3.5T Prestige AWD's 12.6 L/100 km. Over a year of commuting, school runs, and highway trips, those savings at the pump add up.
The published horsepower and torque figures for both vehicles appear in the table above. What sets the MDX apart is that its fuel economy advantage holds at every comparable trim level, not only in a single configuration.
MDX SH-AWD Tech, A-Spec, and Platinum Elite A-Spec: 11.2 L/100 km combined
MDX Type S Ultra: 12.4 L/100 km combined
GV80 2.5T Advanced AWD: 11.3 L/100 km combined
GV80 3.5T Prestige AWD: 12.6 L/100 km combined
Interior Space and Practicality
Passenger and cargo volume tell a similarly consistent story. The MDX's cabin measures 3,939 L of passenger volume on its Tech, A-Spec, and Platinum Elite A-Spec trims, well ahead of the GV80's 3,078 L. That extra interior air translates into noticeably more shoulder and leg room for second- and third-row passengers on longer drives.
Cargo space follows the same pattern. With all three rows in use, the MDX offers 461.6 L behind the third row, compared to 328.5 L in the GV80, a real difference when loading strollers, hockey bags, or a week of groceries. Fold the third row down and the MDX still leads, at 1,107.2 L versus the GV80's 1,033.6 L.
MDX passenger volume: 3,939 L versus GV80's 3,078 L
MDX cargo behind third row: 461.6 L versus GV80's 328.5 L
MDX cargo with third row folded: 1,107.2 L versus GV80's 1,033.6 L
Which Model Is Right for You?
For buyers cross-shopping these two three-row luxury SUVs, the decision often comes down to how the vehicle gets used week to week. Families hauling sports equipment, carpooling multiple kids, or planning long road trips will notice the MDX's larger cabin and cargo areas immediately. Drivers who track fuel costs over years of ownership will see the MDX's efficiency edge reflected at every fill-up, across every comparable trim.
On the factors that matter most for everyday three-row ownership, cabin space and running costs, the documented specifications point clearly to the MDX.
