CarGurus Analysis: 2018 INFINITI Q50
Summary
With 723 currently listed for sale and an average price of $16,606.00, 26.6% of 2018 INFINITI Q50s for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 INFINITI Q50 4.47 / 5 stars.
54.6% of 2018 Q50 models on CarGurus are accident free.
Why it stands out
The 2018 INFINITI Q50 stands out as a midsize premium sedan that leans on a strong mix of power, equipment, and value. It was part of a long-running first generation that changed only gradually, and for 2018 it received mild styling updates along with an upgraded infotainment system and new steering wheel designs. That makes it appealing to buyers who want a luxury sedan with a familiar formula rather than a radically different one.
What helps define the 2018 Q50 most is its standard equipment and broad feature set. Even early models were well equipped, and the Q50’s trim structure gave shoppers a clear path from entry-level versions to more upscale choices. The car also offered rear-wheel drive or all-wheel drive, and its available engines were known for strong performance. Owner feedback lines up with that character, with drivers praising the Q50’s performance, features, handling, power, and acceleration.
There are tradeoffs, though. Fuel economy was never a strong point, and the Q50’s limited model range and long, largely unchanged production run meant it could feel dated compared with newer rivals. Some owners also felt it lacked modern technology features and that the ride could be more comfortable. Even so, the 2018 INFINITI Q50 remains distinctive for buyers who value a well-equipped, powerful 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.
