The Infiniti Q45 is a full-size luxury sedan manufactured by Nissan for its Infiniti brand, spanning model years 1989-2006 and three design generations.
The first generation Q45 (1989–1999) was based on the Nissan President; the second generation (1997–2000) and third generation (2002–2006) were based on Nissan's JDM Nissan Cima. Marketing of the Q45 ended after MY 2006.

The first generation Q45 came to market in 1989 as a 1990 model with a high-output 4.5 L VH45DE DOHC 32V V8 engine rated at 278 hp (207 kW) and 292 lb⋅ft (396 N⋅m) in North American trim. All Q45s included a viscous limited-slip differential and a multi-link suspension at the front and rear. [4] Nissan chose to position it as a luxurious performance sedan, installing technology that would achieve this purpose, and used the letter "Q" from the western tradition of the Q-car meant to imply that its unassuming appearance hid its performance capabilities. At launch, the US$38,000(equivalent to $93,000 in 2023) sedan had a single option, the Touring Package, which added Nissan's Super HICAS four-wheel steering system, a decklid spoiler, and alloy wheels. [5]
In Japan, it was marketed as the Nissan Infiniti Q45, and was exclusive to Nissan Prince Store locations, as its platform twin the President was exclusive to Nissan Store locations. The G50 chassis continued in production in Japan until 2002 as the President in both regular and extended wheelbase versions. The Japanese version had many options that never appeared on the North American G50.
The contemporary upstart luxury marque Lexus (Toyota) had managed to challenge the established dominance of European full-size luxury cars with the LS 400, so the Q45 seemed poised for similar success with comparable specifications and price to the LS 400 while featuring more emphasis upon handling. However, the Q45 did not achieve similar sales volumes, which was attributed to the car's unconventional styling, particularly the grille and lack of interior woodgrain or chrome trim. There was also an unusual advertising campaign which did not include actual photos or information about the car. [6] [7] [8] By 1995, the price had risen to US$54,000(equivalent to $108,000 in 2023), slowing sales. [9]
In 1993 the Infiniti brand was launched in Australia with the sole model on offer being the Q45. With a price of A$140,000, the Q45 sold poorly and the brand was subsequently withdrawn from the market in 1996. [10] [11]
According to the design team, the Q45 was meant to "express the Japanese concept of luxury" by incorporating traditional Japanese craftsmanship; as initially released, there was no front grille and no wood paneling on the dashboard. [12] Nissan received assistance from Poltrona Frau for the minimalist interior. [13] A grille was added in 1993 and interior wood had appeared by 1995. [14]
Nissan had launched a program called the "901 Movement" or "901 Activity" in 1985, with the goal of "realizing the No. 1 operating performance in the world by 1990", [15] making Nissan's the best handling lineup in the industry. [16] Other vehicles resulting from the "901" program included the 300ZX (Z32), Primera (P10), Silvia (S13), and Skyline (R32); [15] [17] the multi-link suspension of the Q45 was derived from the Z32. [18]
In 1989 (as a 1990 model) "Full-Active Suspension" was introduced with the Q45a model, which employed 10 sensors sending signals to microprocessor-controlled one-way hydraulic actuators at each wheel, designed to reduce body roll, dive, and pitch. [19] The suspension provides an active response to road features up to approximately 3 Hz, a limit imposed by minimizing the size of the additional hardware and power losses required to pressurize the hydraulic accumulator; [19] it added 202 lb (92 kg) and reduced fuel economy by 10%. [20] The system was brought to the United States starting in 1990 for the 1991 model year. [21] [22] At about the same time, Toyota marketed a limited-production Celica Active Sports (ST183) in Japan with its Toyota Active Control Suspension. [19] Mercedes-Benz also developed a similar system named Active Body Control, which was introduced a decade later in 1999 on the C215 CL-Class.
The Q45t model added Nissan's Super HICAS four wheel steering system and firmer suspension. [23] A trunklid spoiler was included, reducing drag. [24] However, HICAS was deleted for the 1995 Q45t. [14]
Standard equipment included a Bose sound system, leather interior, power adjustable front passenger seats with two position memory feature that also electrically adjusted the steering wheel, exterior mirrors, one-touch power windows, digital climate control, and keyless entry system.
Revisions in 1993 included 17:1 steering (except on the Q45t, which retained the original 15.1:1 ratio), lower ratio 1st and 2nd gears, and a dynamically smooth suspension, thicker glass, keyless remote, auto-dim rear-view mirror, dipping side view mirrors, revised transmission heat exchanger and external ATF filter, revised oval intake ports and revised disc injectors, fog lights and metal-backed camshaft timing chain guides.
Infiniti offered the Q45 in three trim levels: base, Q45t, and Q45a. All models featured a multi-link suspension at both the front and rear wheels, and the Q45t and Q45a added a rear stabilizer bar, with the Q45a model being larger in diameter; both models have a 1 mm smaller in diameter front sway bar, rear spoiler, BBS forged alloy wheels, 4-wheel steering.
Externally, the 1994 and later model year Q45 can be distinguished by a chrome grille. [14] HICAS and the faster steering ratios was discontinued in the 1995 Q45t model and the Q45a model was not imported in 1996. [25] 1996 models do not feature variable valve timing like the 1990-1995 models do. OBD-II was added for the 1996 model year.

The second generation Q45 was a lightly revised variant of the Nissan Cima for the Japanese Domestic Market, [26] which shared a common platform with the Cedric / Gloria (Y33 generation). For most of its vehicles, Infiniti uses a naming convention that combined a letter indicating the series or market position, followed by a two-digit number for engine displacement; for instance, the first generation Q45 (G50) name designates the flagship (Q-series) followed by 45 for its 4.5-liter V8; the second-generation Q45 was an exception (as was the QX4, derived from the contemporary Nissan Pathfinder), as it used a smaller 252 cu in (4.1 L) VH41DE engine. [26]
Styling featured an inverse curve C-pillar, and a pronounced full-length horizontal character beltline. Despite the shorter wheelbase in the Y33 compared to the G50, rear legroom increased by 3.9 in (99 mm); however, the trunk was faulted by owners as being small, with a volume of 12.6 cu ft (360 L). [27] Standard features for the second-generation Q45 included traction control, leather interior with faux wood trim, single (later dual) zone climate control, Bose audio system with eight speakers and in-dash single disc CD player, auto dimming rear view mirror, automatic light on and delay off timer, steering wheel-mounted cruise control and head unit controls. Also standard was a memory system for the driver's seat and steering wheel. [27] Available options included an integrated satellite navigation system, 6-disc CD autochanger and heated seats.
The touring package, again badged as the Q45t, featured 17-inch wheels and tires, electronically modulated performance-tuned suspension, blackout grille, blackout headlight treatment, and performance style steering wheel. [27]
The front suspension was changed to a MacPherson strut; rear suspension was similar to the G50, using a multilink design. [28] The second generation Q45 (Y33) was equipped with a viscous LSD and electronic traction control as standard features. Compared to the first generation (G50), the Y33 was approximately 200 lb (91 kg) lighter, and the steering ratio was slowed further, from 17.0:1 to 18.5:1. [26] As Edmunds noted for the 1997 model year, "The Q45 no longer has aspirations to be a sport sedan, its prime duties now are interstate cruising." [25]
The Q45 (Y33) equipped with the VH41DE producing 267 hp (199 kW) and 278 lb⋅ft (377 N⋅m) was able to accelerate from 0 to 60 mph (97 km/h) in approximately 7.5 seconds. [28]
The Q45 front and rear fascias were slightly revised for 1999; HID headlights and an analog clock became standard equipment. [25] [29] Five-spoke 17" aluminum alloy wheels and an electronic adjustable suspension became standard on the Q45t. [30]
The Q45 Anniversary Edition, limited to 3,000 units, offered highest trim level available for the second-generation Q45, available on 2000 models and standard on the 2001 models. The package included all features of the Q45t model along with "Anniversary Edition" markings on the tailgate badge, ignition key, front seat embossing and floor mats as well as genuine wood trim, wood tone/leather steering wheel, special bright machine finish 17-inch performance wheels and exclusive body color door handles.

Introduced as a concept at the 2000 New York Auto Show, [35] the third generation Q45 (F50) was, like the preceding Q45 (Y33), based on the JDM Cima, featuring a new 4.5 L VK45DE V8 engine, HID headlights and a 5-speed automatic transmission with overdrive. [36] It was marketed one year later, starting from April 2001, for the 2002 model year, [37] at a starting MSRP of US$50,500(equivalent to $86,900 in 2023). [38]
The third generation Q45 was reviewed by Car and Driver , Edmunds and Consumer Guide, receiving relatively positive reviews. [39]
Development began in 1996, with exterior designs by Mamori Aoki frozen in 1998 and patented in March 2000. [40] [41] Aoki said the styling was meant to evoke "a driver's car, not a chauffeur-driven limousine." [37] Compared to the prior generation (Y33), the third generation Q45 (F50) is wider and has a longer wheelbase, contributing to a 5 cu ft (0.14 m3) increase in interior volume; [37] torsional rigidity has improved by 40%. [42]
It was the first Infiniti with a laser-based autonomous cruise control system. [43] Standard equipment included a leather interior, power sunroof, 8-way power front seats, remote keyless entry, rain-detecting wipers and side curtain airbags. Standard electronics include: CD, 8 speaker Bose audio system, trip computer, rear view parking camera system, and voice-activated navigation system. The 2002 Q45 was the first vehicle ever to offer voice-controlled navigation and a reverse parking camera outside Japan, following the JDM 1991 Toyota Soarer. [44] The Q45 seated five passengers.
The suspension of the Q45 (F50) consists of front struts and multi-link rear, with anti-roll bars on both. [37]
The optional Premium Package included adjustable suspension, 18-inch 8-spoke titanium-color sport alloy wheels, 245/45R18 V-rated tires, rear monitor, rear power sunshade and rear door manual sunshades, climate controlled front seats with heating and cooling functions and perforated leather inserts, navigation system with 7.0-inch LCD display, Intelligent Cruise Control, satellite radio, auto open/close trunk, heated power-reclining rear seats with memory, rear controls for audio and HVAC and rear HVAC vents in B-pillar and front seatback grips — and available chrome-finished 18-inch wheels in place of the titanium wheels. [45] [46]
The VK45DE has a maximum output of 340 hp (254 kW) and 333 lb⋅ft (451 N⋅m), [33] motivating the Q45 (F50) sedan from 0 to 60 mph (97 km/h) in 6.0 seconds. [39]
The 2003 model received a revised security system, numerically higher final drive ratio (for better acceleration - decreased highway fuel economy), reprogrammed TCU, and a mid-year satellite radio option. The CD changer could load CDs directly at the dashboard head unit.
For 2005, the Q45 received a mild facelift, with revised front and rear fascias; hood; grille; trunk decklid and finisher; headlights; side, front and rear chrome accent trim; and integrated fog lights and LED taillights. The interior featured re-contoured double-stitched seating, all white luminescent gauge markings, genuine metal knobs for accessory controls, a darker shade of maple interior trim, recalibrated transmission and new 17" alloy wheels. 1129 Q45s were marketed in the United States for 2005.
The Infiniti Q45 was no longer exported to the USA after 2006, its flagship position in the Infiniti line assumed by a newly redesigned Infiniti M35/45, an mid-luxury (executive) car shorter in length than the Q45, though with greater interior room and performance, as well a featuring a rear multilink suspension and front double wishbone.
A new Infiniti flagship was anticipated by the end of the 2000s decade. According to Mark Igo, the general manager of Infiniti North America, "the new Q will make the brand better, but it is questionable whether it will be very profitable". [47]
Infiniti introduced the next iteration of its flagship, the Y51 series Infiniti M37/56/Nissan Fuga in November 2009. Continuing as a mid-luxury car, the new Infiniti M is only 50 mm (2.0 in) shorter than the final generation Q45, with the same width dimensions of 1,845 mm (6.1 ft) and height of 1,515 mm (5.0 ft) compared to the F50 series Cima of 1,490 mm (4.9 ft) height.
By August 2010 the Nissan Cima, on which the final generation Q45 essentially was based, had been discontinued in Japan, along with its Nissan President sibling. This made the second generation Nissan Fuga the marque's top-of-the-line flagship sedan. When the Fuga assumed the role as flagship sedan of Nissan Japan August 2010, it became the first time that Nissan didn't sell a premium luxury V8 sedan in Japan, although the Fuga's North American cousin, the Infiniti M56, is offered with a V8 shared with the Infiniti QX56.
In May 2012, Nissan released a new version of the Cima in Japan, based on the Fuga Hybrid (Infiniti M35h). [48]
On 17 December 2012, Infiniti announced that all of its future sedan offerings will use the Q prefix, starting from the Q50 as a G37 replacement, Q70 for its M35/45/56 replacement, and a rumored Q80 for the new flagship model. [49]
Infiniti is the luxury vehicle division of the Japanese automaker Nissan. Infiniti officially started selling vehicles on November 8, 1989, in North America. The marketing network for Infiniti-branded vehicles included dealers in over 50 countries in the 2010s. As of 2020, there were 25 markets served by new car dealers. The main markets are North America, China, Taiwan, and the Middle East.
The Nissan Maxima is a car manufactured and marketed by Nissan and offered as Nissan's flagship sedan primarily in North America, the Middle East, South Korea, and China—and currently in its eighth generation. Having debuted for model year 1982 as the Datsun Maxima, it replaced the earlier Datsun 810. The name Maxima dates to the 1981 model year when Datsun marketed the upscale 810 as the 810 Maxima in North America. Like the 810, early versions of the Maxima had their origins in the Datsun/Nissan Bluebird. It is renamed to Nissan Maxima when the Datsun brand was phased out for the 1985 model year.
The Nissan Pathfinder is a range of sport utility vehicles manufactured by Nissan since 1986. Until the third-generation model, the Pathfinder is based on Nissan's compact pickup truck platform which it shares with the Navara/Frontier. The front end of the D21 and R51 Pathfinder is notably identical with the Navara/Frontier up until the B-pillars.
The Infiniti J30, marketed as the Nissan Leopard J Ferie in Japan, was a rear wheel drive luxury car. The J30 went into production on April 7, 1992 as a 1993 model to replace the M30, and was launched in the United States after its competitors, the Lexus GS and Acura Legend. The car was sold in the mid-size sedan segment between the smaller G20 and the larger Q45, both by size and price. The small interior resulted from its rounded styling uncharacteristic of the crowded executive car class, which is now considered an early variant of a four-door coupé.
The Acura Legend is a mid-size luxury car manufactured by Honda from Japan. It was sold in the U.S. and Canada under Honda's luxury brand, Acura, from 1985 until 1995. It was the first flagship sedan sold under the Acura nameplate, until being renamed in 1996 as the Acura 3.5RL. The 3.5RL was the North American version of the KA9 series Honda Legend.
The Nissan Fuga is a mid-size luxury sedan produced by Japanese automaker Nissan since October 2004. It is built on a wider, stretched wheelbase version of the Nissan FM platform. After the Nissan Cima and Nissan President were discontinued in August 2010, the Fuga became Nissan's flagship vehicle. In North America and Europe, the Fuga was sold as the second and third-generation Infiniti M and Infiniti Q70, where it was the flagship sedan of the Infiniti luxury division of Nissan from 2006 to 2019.
The Infiniti M is a line of mid-size luxury (executive) cars from the Infiniti luxury division of Nissan. From 2013 on it has been marketed as the Infiniti Q70, reflecting the company's new naming scheme.
The Nissan Cefiro is a mid-size passenger car manufactured and marketed by Nissan Motors over three generations. Almost all Cefiro's were marketed as four-door sedans, though a five-door wagon body style was briefly available (1997–2000). In most cases, the Cefiro used Nissan's VQ six-cylinder engines, named Ward's 10 Best Engines more than ten years running.
The Honda Legend is a series of V6-engined executive cars that was produced by Honda between 1985 and 2021, and served as its flagship vehicle. The Legend has also been sold under the Acura Legend, RL and RLX nameplates — the successive flagship vehicles of Honda's luxury Acura division in North America from 1986 until 2020.
The Nissan Laurel is a two- and four-door sedan manufactured and marketed by Nissan from 1968 to 2002. Later generations added all-wheel-drive along with turbocharged engines. Introduced in 1968 as a new model positioned above the Datsun Bluebird 510, the Laurel offered the luxury of the Nissan Gloria A30 in a shorter wheelbase, and has always been the luxury version of the Skyline range for all generations, sharing engines, suspensions and handling dynamics of the popular performance coupe and sedan while having a longer wheelbase.
The Gloria is a large luxury car made from 1959 by the Prince Motor Company, and later by Nissan Motors since its merger with the former - hence being originally marketed as Prince Gloria and later as Nissan Gloria. Initially based on the smaller Prince Skyline, the Gloria line was merged with Nissan Cedric starting with 1971 models and both continued until 2004, when they were both replaced by Nissan Fuga.
The Nissan Cedric is a large automobile produced by Nissan from 1960 to 2015. It was developed to provide upscale transportation, competing with the Prince Skyline and Gloria which were later merged into the Nissan family. In later years, the Nissan Skyline was positioned as a sports sedan/coupe, whereas the Nissan Gloria was turned into a sporty version of the Cedric.
The Nissan President is a Japanese luxury sedan that was manufactured and marketed by Nissan from 1965 until 2010 as the flagship of Nissan's range, available only at its Nissan Store dealerships then at Nissan Blue Stage dealerships.
The Nissan Cima is a luxury sedan manufactured and marketed by Nissan for the Japanese market. The name Cima is derived from Spanish for "summit". Earlier generations featured a hood ornament with an image of an acanthus leaf that was the naming basis for the Nissan Laurel. The acanthus leaf was commonly used by classical Greeks to make a wreath for use as a crown.
HICAS is Nissan's rear wheel steering system which was fitted to cars from approximately 1985 to 2010, including models ranging from the Skyline and Fairlady Z (Z32) to smaller vehicles like the Nissan Cefiro (A31), Silvia /240SX/180SX and Nissan Serena/Nissan Largo. It is also found on models from the Infiniti division, such as the Q45, J30, M45/M35 and G35/G37.
The Infiniti G Line is a series of compact executive cars manufactured and marketed by Infiniti, a luxury division of Nissan, for the 1991–1996 and 1999–2016 model years — across four generations.
ATTESA is a four-wheel drive system used in some automobiles produced by the Japanese automaker Nissan, including some models under its luxury marque Infiniti.
The Nissan Leopard is a line of sport/luxury cars built by Japanese carmaker Nissan. The Leopard began life in 1980 and was discontinued in 1999. The Leopard were initially based on the Japanese market Nissan Skyline and Nissan Laurel, then later based on the chassis of their Nissan Cedric and Nissan Gloria contemporaries and were rear wheel drive. Final versions were the contributing factors to Nissan's Infiniti M and J products.
The Mitsubishi Dignity is a full-size luxury car originally manufactured by Mitsubishi Motors from late 1999 to 2001 as the flagship of the company's domestic range, alongside the shorter Proudia, and was reintroduced 2012 to Japanese buyers as a rebadged fifth-generation Nissan Cima. The Dignity was discontinued for the second time in 2016. In Japan, it was sold at a specific retail chain called Galant Shop.
The Infiniti QX80 is a full-size luxury SUV marketed by Nissan's luxury division Infiniti. The first-generation QX56 was built in the United States and is based on the first-generation Armada. The second-generation model was released in 2010 as a model produced in Japan, which used the sixth-generation Patrol as the base vehicle instead. Since the 2014 model year in 2013, the vehicle was renamed to the QX80 as Infiniti renamed their entire product line under a new nomenclature.
The memory, however, of the loony launch of the Q45 back in 1990, however, seems to have transited the Atlantic and manifested itself in the hyper-cheese storm-brewing Flash video that new luxury automaker Eterniti has posted on its website. The thing about the O.G. Q45 ads—which also served to introduce Nissan's then-new luxury brand to the American public—is that they didn't feature the car.
The Infiniti's cabin couldn't be more different from the Jaguar's. It consciously eschews wood and chrome for a monochromatic and spare look conceived with input from Italian furniture maker Poltrona Frau. It's more modern-feeling; the seats are more couch-like; and the ergonomics are more intuitive than the Jag's.
In the mid 1980s, the R&D division of Nissan began the so-called "901 Activity", an effort to achieve the new goal of "realizing the No. 1 operating performance in the world by 1990". Nissan's new challenge for R&D lead [ sic ] to numerous excellent products, such as the "PRIMERA model P10" and "Skyline model R32", spreading the image of Nissan as a technology company throughout the world.
