2018 INFINITI Q50 VS. 2018 MERCEDES-BENZ C CLASS | Competition INFINITI of Smithtown


The INFINITI 2018 Q50 is a dynamic sedan that is coveted by many. However, the 2018 Mercedes Benz C Class manifests a spectacular exterior combined with the formidable power of its own, along with a host of luxury features. Which car is the better buy? Find out now!

Design & Style

Both vehicles look good on the outside and inside, without being over the top. They come in a variety of colors and trim, and owners can customize them to their liking. However, externally the INFINITI Q50 is a bit more intricate than the Mercedes C Class, which some have described as being rather plain by comparison. The two vehicles are evenly matched when it comes to interior luxury amenities, and those driving either will have access to the latest gadgets and features.

Technology & Safety

The Mercedes Benz C Class has a stronger powertrain than the INFINITI, but the Q50 has superior hybrid efficiency. Some, however, have complained about the Q50’s adaptive steering, which leaves a lot to be desired, while the rear seats in the Mercedes C Class are tighter than they should be. The Mercedes has a slight edge in fuel economy, at 24 mpg versus only 23 mpg for the INFINITI Q50, and although both cars seat a maximum of 5, those driving the INFINITI Q50 will have more space.


Both cars feature a 4 wheel anti-brake system with rack pinion steering and aluminum front wheels. However, the Mercedes Benz C Class has a decisive edge in raw power, at 241 horsepower at 5550 rpm versus only 208 horsepower at 5500 rpm for the INFINITI Q50. Both vehicles utilize Intercooled Premium Unleaded Turbo I-4 Engines with direct gasoline injection, along with rear wheel drive. The INFINITI Q50 does have a higher fuel tank capacity, at 20 gallons versus only 17.4 for the Mercedes, but the Benz has slightly stronger torque at 273 at 1300 rpm versus only 258 at 1500 rpm.

The Bottom Line

Overall, these two vehicles are closely matched in a number of areas. While the INFINITI Q50 offers more space than the Mercedes Benz, the C Class outpaces it in terms of performance. However, this comes at a considerably higher price. The thing is, most people don’t buy luxury sedans for performance (that’s what coupes are for), so many will have a hard time justifying paying extra money for a vehicle that has merely a slight performance edge. Therefore, it is clear that the INFINITI Q50 offers the better value.
