Key Differences
-
The XT4 has 45 hp more power
Big gap, real consequences. The XT4’s 235 hp versus the ADX’s 190 hp changes how the two compare in daily use. The XT4’s extra output gives it more in reserve when you need to get up to speed.
-
The XT4 has 79 lb-ft more torque
The ADX is clearly behind on torque (179 lb-ft against 258 lb-ft), and that’s one of its biggest weak spots in this matchup. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The ADX has 8.4% more cargo space
Not a big gap, but a consistent one. The ADX’s 24.4 cu ft beats the XT4’s 22.5 cu ft. Cargo figures are measured in different ways by different makers, so small gaps may not show in practice.
-
The ADX has better fuel economy
The ADX wins this narrowly, 28 mpg against 26 mpg, which makes it more of a bonus than a reason to buy. The ADX uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The ADX has 13% more maximum cargo space
The ADX has a modest edge on cargo (seats folded): 55.1 cu ft against 48.9 cu ft for the XT4. Check the shape of the load floor too: a flat floor can matter as much as the number.
Design & Size
Want the smaller footprint? That’s the XT4. The ADX is the larger of the two.

Engine & Performance
XT4 leads
In this area the XT4 has a lead the ADX can’t close. The XT4 wins here with 45 hp more power. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels. Prioritize engine & performance, and the XT4 is where you should land.
Total system output
ADX: 190 hp XT4: 235 hp More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.
Torque
ADX: 179 lb-ft XT4: 258 lb-ft The XT4’s extra torque makes it more relaxed when fully loaded or towing.
Fuel Economy & Range
ADX leads
This is one of the ADX’s strongest areas. On fuel economy & range, the XT4 falls well short. The ADX has the edge with better fuel economy. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership. The takeaway: on fuel economy & range, the ADX is the stronger car.
Fuel economy (combined)
ADX: 28 mpg XT4: 26 mpg Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
Fuel economy (city)
ADX: 26 mpg XT4: 24 mpg City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
Space & Practicality
ADX leads
The XT4 is outclassed on space & practicality; the ADX leads by a clear margin. On the ADX, you get 8.4% more cargo space. Cargo space behind the rear seats is what you use every day for groceries, strollers and luggage. So if space & practicality tops your list, lean toward the ADX.
Cargo (behind rear seats)
ADX: 24.4 cu ft XT4: 22.5 cu ft The ADX’s larger cargo area makes family trips and big shopping runs easier.
Cargo (seats folded)
ADX: 55.1 cu ft XT4: 48.9 cu ft Maximum cargo space with the seats folded matters when you move furniture, bikes or bulky gear.
Off-road & Towing
Too close to call
Neither the ADX nor the XT4 has a real advantage in the off-road & towing category. Bottom line for off-road & towing: it’s a wash.
Safety & Tech
The safety & tech comparison is about what’s inside rather than how much. See the table for the ADX’s and the XT4’s entries.
