Why it stands out
The 2018 INFINITI Q50 is a midsize premium sedan that offers a compelling blend of performance, luxury, and value. It stands out with its powerful engine options, including a robust V6, and a well-equipped interior that features many standard amenities. While it competes closely with rivals like the BMW 3 Series and Audi A4, the Q50 provides a unique combination of sportiness and comfort. However, some drivers have noted that it lacks the latest technology features and that the ride could be more comfortable. Despite these limitations, the Q50 remains an attractive option for buyers seeking a powerful and well-appointed sedan at a competitive price.

Highly recommend this car! We were looking to purchase either the Kia Stinger GT2, Genesis G70 or the Q50 Red Sport. Never got to drive a G70 due to limited stock, but got to test drive the Kia Stinger and compared to the Q50 it wasnt even close. The Q50 has much better rideability, more refined, quieter and faster. We are looking forward to enjoying this plush sleeper for many years.
