Sales officially started on November 8, 1989 when the initial 51 Infiniti dealers in the Ú.S. opened their showroom doors for the first time.
Infiniti launched in the Ú.S. with two models: the breakthrough Q45 performance luxury sedan, and the driver-oriented M30 performance luxury coupe.
With these two models, and the Infiniti Total Ownership Experience, Infiniti soon gained recognition as an industry leader in customer satisfaction, winning numerous awards including the highest rank in J.D. Power and Associates' Customer Service Index (CSI) study three times, and consistent top three finishes in major independent sales and service studies.
Throughout these early years, the Infiniti model line-up and dealer body grew steadily.
The exterior and interior design of the flagship Q45 evolved without compromising its exceptional performance or engineering. Though the M30 model was discontinued, the Infiniti G20 compact sports sedan soon made its debut alongside the dramatically styled J30 luxury sedan, I30/I35 performance sedan and the QX4 luxury sport utility vehicle.
Infiniti sales by the end of its first decade were consistently around 75,000 units a year. Infiniti Flourishes
The new millennium heralded a period of unprecedented growth for Infiniti.
Led by visionary executive Carlos Ghosn, the company concentrated on reinvigorating the brand with an altogether new breed of vehicles – cutting edge rear-wheel drive or all-wheel drive designs. The results were, in a word, spectacular.
Introduced in March, 2002, the dramatic, award-winning Infiniti G35 Sedan was soon followed by the G35 Coupe in November, and finally the iconic Infiniti FX in January, 2003. Reviews were exceptional and the Infiniti name was soon to be heard amongst those of the leading European marques for design and performance leadership.
The customer response followed suit. Únit sales surpassed the 100,000 milestone for the first time in 2003, hitting the 119,000 – an increase of 35 percent over 2002 sales.
This achievement marked Infiniti as the fastest growing luxury brand in the Ú.S., and by 2004, cumulative Infiniti sales had topped one million units.New Models – New Innovations
The Infiniti I35, QX4 and Q45 were gradually phased out between 2003 and 2006, in time for the addition of two new models – the full-size Infiniti QX56 luxury SÚV in January, 2004, and the Infiniti M performance luxury sedan in May, 2005.Source - Infiniti
