2017 INFINITI QX30 vs. 2017 MERCEDES-BENZ GLA-CLASS | Competition INFINITI of Smithtown


INFINITI is Nissan’s premium brand and has recently expanded its lineup into a number of segments. The company has minimal interest in car models which take more than one generation to match competition like the Mercedes Benz GLA Class, so it switched gears to develop the QX30, which is a crossover vehicle that has proven quite popular among customers in St. James, New York.

Design & Style

The 2017 INFINITI QX30 is a crossover vehicle which is both tall and rugged. It comes in three variants, which the company believes is sufficient to cater to the demands of multiple demographics. These variants are the QX30, QX30 AWD and QX30 Sport. Each has a distinct trim level. Each version utilizes INFINITI’s InTouch system for navigation and can be matched with as many as ten unique trim or tech packages.

The Mercedes Benz GLA class comes with a wheelbase that is 106.3 inches, an automatic transmission which is dual clutch and seven speed, and inline four which is turbocharged to 2.0 liter. The body of the car is a bit softer than the QX30 and isn’t as impressively sculpted, but its torque and horsepower are a match. The Mercedes Benz GLA is luxurious and sporty, but also has an entry cost which is a bit steeper than its INFINITI rival. The interior of the Mercedes looks great, but incorporates a finish and fit material which isn’t up to their normal standards. The car seats four people, but since the roofline is tapered, headroom will be compromised for passengers who are taller.

Technology & Safety

The INFINITI QX30 has a four wheel ABS system, as does the Mercedes GLA. However, the Mercedes has a slightly larger fuel tank capacity, at 14.8 gallons versus only 13.2 gallons for the QX30. Both cars use the very popular rack-pinion steering mechanism, and overall, the INFINITI weighs slightly less. The material of the wheels is mostly aluminum for both brands, but the Mercedes GLA has a slightly higher alternator capacity at 115 versus the QX30’s 110.

Many car consumers are picky about the engine their vehicle uses, but both are equal in this regard, incorporating an Unleaded 1-4 Turbo Premium Intercooled Engine. The fuel system used by the Mercedes GLA and QX30 are both direct gasoline injection.


When it comes to performance, the Mercedes GLA edges out the QX30, but only slightly. While both have a net horsepower of 208 @ 5500 and displacement of 2.0 L/121, the QX30 has a torque of 258@ 1200 while the Mercedes has 258@ 1250.

The Bottom Line

While the Mercedes GLA-Class is a truly impressive vehicle, the QX30 is a better buy overall. It is sleeker on the outside, more comfortable on the inside, has a lower price tag and the performance is nearly on par with the Mercedes-Benz GLA-Class. If you’re looking for luxury without breaking the bank then the QX30 is the way to go.
