Generations and History of INFINITI Q
The “Q” nomenclature in INFINITI’s lineup has a rich history, beginning with the brand’s inception. It has been used to denote their sedans and coupes, distinguishing them from the “QX” line of SUVs.
The Original: INFINITI Q45
The INFINITI Q45 was the flagship sedan that launched with the INFINITI brand in 1989. It was a full-size luxury car designed to compete with the established European and American luxury brands.
First Generation (1989-1996)
Based on the Japanese-market Nissan President, the first-generation Q45 was notable for its powerful 4.5-liter V8 engine and a design that eschewed the traditional front grille for a more distinctive look. It offered a driver-focused experience with a well-appointed interior.
Second Generation (1997-2001)
The second generation was a rebadged version of the Nissan Cima and featured a smaller 4.1-liter V8 engine. This iteration had a more conventional design and aimed to provide a more refined and comfortable luxury experience.
Third Generation (2002-2006)
The final generation of the Q45 returned to a 4.5-liter V8, this time producing 340 horsepower. It featured a more dramatic and aerodynamic design and a host of advanced technologies for its time. The Q45 was discontinued after the 2006 model year.
The Successors: Q40, Q50, Q60, and Q70
Following a brand-wide renaming strategy, INFINITI introduced a new series of “Q” models.
INFINITI Q40
The INFINITI Q40 was a short-lived model, essentially a continuation of the G37 sedan for the 2015 model year. It was powered by a 3.7-liter V6 engine and was available with either rear-wheel or all-wheel drive.
INFINITI Q50
Introduced in 2013 as a 2014 model, the Q50 replaced the G37 sedan. It has been one of INFINITI’s most popular models, offering a blend of performance and luxury.

The Q50 was discontinued after the 2024 model year.
INFINITI Q60
The Q60 is the coupe counterpart to the Q50. The first generation was a rebadged G37 coupe. The second generation, introduced for the 2017 model year, featured a stunning design and shared the powerful twin-turbo V6 engines with the Q50. Production of the Q60 ceased after the 2022 model year.
INFINITI Q70
The Q70, previously known as the M-series, was INFINITI’s mid-size luxury sedan. It was available with V6 and V8 engines, as well as a hybrid powertrain. A long-wheelbase version, the Q70L, was also offered. The Q70 was discontinued in 2019.

INFINITI Q Engine, Performance, and Driving Experience
The INFINITI Q series has always been synonymous with a sporty and engaging driving experience. The flagship Q45 was initially lauded for its powerful V8 engine that provided strong acceleration. The more modern Q50 and Q60 continued this tradition with their potent twin-turbocharged V6 engines, especially the 400-horsepower Red Sport 400 variants which offered exhilarating performance. The Q40 was equipped with a robust 3.7-liter V6 producing 328 horsepower. The Q70 provided a choice of a capable V6 or a powerful V8, delivering a refined yet sporty ride. Many Q models were built on Nissan’s FM (Front Midship) platform, which places the engine further back in the chassis for better weight distribution and handling dynamics.

Pricing for INFINITI Q models varied significantly depending on the model, trim level, and model year. As new vehicles, they were positioned to compete with other luxury brands. For example, the 2015 Q40 started at an MSRP of $33,950 for the rear-wheel-drive model. In the used market, prices can range from a few thousand dollars for older, high-mileage examples to near-new prices for recent, low-mileage vehicles. Mileage also varied greatly across the lineup. The 2015 Q40 with all-wheel drive had an EPA-estimated combined MPG of 20. Hybrid versions of the Q50 and Q70 offered improved fuel economy.
