2018 INFINITI Q50 VS. 2018 HYUNDAI SONATA | Competition INFINITI of Smithtown


The 2018 Hyundai Sonata is a big improvement over previous editions, with greater styling, space, and engine flexibility. But how does it stack up against the mighty 2018 INFINITI Q50, a vehicle prized for its beauty, the efficiency of its engine, and enhanced interior?

Design & Style

The exterior of the INFINITI Q50 is similar to previous editions, with running LED lights and curves. Moderate changes have been made to the cabin, to maximize its comfort and opulence. The steering wheel spokes are thinner and the dash is stitched. The ambient lighting has been enhanced, along with an infotainment unit consisting of two screens. The wood trim is also very impressive. The Hyundai Sonata is not too far off, both in the exterior and interior. Although the brand has traditionally been known for its economy class vehicles, they have demonstrated with the latest Sonata that they can do upscale. This is evident by the 7-inch infotainment screen, front fascia, extended roof, hexagonal grille, and outstanding trim.

Technology & Safety

The Hyundai Sonata has a good score when it comes to crash tests. Both independent and federal agencies have praised it for its safety devices, which include stability control, seven airbags, a camera in the rearview, emergency automatic brakes, alerts for cross traffic, and monitoring for blind areas. The Sonata is also equipped for comfort, and passengers can expect power locks and windows, Android Auto or Apple Carplay, Bluetooth support, keyless ignition and seats which can be power adjusted ten ways.

Matching and even exceeding the Hyundai Sonata, the INFINITI Q50 has some of the most advanced safety features available on the market. These include Distance Control, where the car will maintain a certain space between it and vehicles in front automatically, active safety systems, emergency automatic brakes, monitoring for blind spots, and cruise control which is adaptive. Additional comforts include climate control which is dual zone, eight-inch touch screens, satellite radio, an audio system with six speakers and LED headlights.


The standard INFINITI Q50 comes with a 2-liter engine that can produce 208 horsepower with 258 pounds of torque, giving it an edge over many Audis and BMWs within the same class. It can be upgraded to more powerful engines, one of which is the V6 and the Red Sports Edition, which can produce 400 horsepower. The Hyundai Sonata comes with a standard inline 4, 2.4-liter engine that can produce up to 185 horsepower with 178 pounds of torque, and uses a direct gasoline injection system which conserves fuel while boosting efficiency. In terms of performance, it is clear that the INFINITI outclasses the Hyundai.

The Bottom Line

While the Sonata and Q50 are neck to neck in a number of areas, the interior of the Hyundai is a downgrade in comparison, and it also falls short when it comes to performance, so the INFINITI wins effortlessly when we are making a comparison.
