Why it stands out
The 2018 INFINITI Q50 is a midsize premium sedan that combines performance, luxury, and value, making it a compelling choice for buyers in the segment. It features a range of powerful engine options, including a twin-turbo 3.0-liter V6 that delivers impressive acceleration and handling. The Q50 is well-equipped with standard features, including automatic LED headlights, dual-zone climate control, and a premium audio system, which enhance its appeal. While it competes closely with rivals like the BMW 3 Series and Audi A4, some drivers have noted that it lacks the latest technology features and could offer a more comfortable ride. Overall, the Q50 remains a strong contender for those seeking a powerful and well-appointed sedan.

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.
