2018 INFINITI QX30 VS. 2018 MERCEDES-BENZ GLA CLASS | Competition INFINITI of Smithtown


The 2018 INFINITI QX30 is prized for its standout design, along with its exceptional handling. The 2018 Mercedes Benz GLA, on the other hand, has the practicality commonly associated with hatchbacks with turbo engines that make it quick and nimble. Which of these vehicles should be in your garage?

Design & Style

While both vehicles have an impressive interior, the interior of the INFINITI QX30 is quite refined. However, some have complained that it is tighter than it should be for a car in its class. The Mercedes GLA also has tight space, especially for its rear seats, and the overall interior, unlike the QX30, can feel plastic at times, which will be a definite turn off for some.

Technology & Safety

Both vehicles are tied when it comes to mpg, at 24. They are both classified as station wagons which mean they have lots of room for cargo, and each can carry a maximum of five passengers. When it comes to space, the vehicles are evenly matched. The Mercedes GLA does have a higher fuel capacity, however, at 14.8 gallons versus only 13.3 gallons for the INFINITI QX30. Each incorporates rack pinion steering along with a 4 wheel drive brake system. When it comes to weight, the vehicles are close, at 3,296 pounds for the Mercedes GLA, and 3,280 pounds for the QX30. Weight is important when it comes to automobiles because it gives you an idea of how well the vehicle maneuvers and accelerates.


Both vehicles incorporate the same engine type, which is the Intercooled Premium Unleaded Turbo I-4 engine. The horsepower is identical, at 208 hp at 5500 rpm for each. Therefore, neither vehicle has an advantage in performance and can be expected to perform at the same level. The QX30 also uses a direct gasoline injection mechanism, which is the same fuel system used by the Mercedes GLA. The Mercedes does have a slight edge in torque, but the difference is so small that it will barely be noticeable.

The Bottom Line

The INFINITI QX30 and Mercedes Benz GLA are the two closest vehicles that have ever been compared. They use the same engine type, fuel system, steering, and have the identical horsepower. They also cost around the same amount, which is a problem for the Mercedes, since its lower quality interior doesn’t justify it. With the INFINITI QX30, you will get everything that the Mercedes Benz GLA has, along with something it doesn’t, which is an elegant, well-designed interior. So the INFINITI is the clear victor.
