Infiniti Q45

From Infiniti press: In November 1985, a task force was assembled at Nissan Motor Corporation U.S.A. to study the needs and desires of luxury car buyers. Four years later, in November 1989, the Infiniti Division was launched -- built on a foundation of fulfilling those needs: a unique dealer network, a previously unobtainable level of customer service and support before and after the sale, and a breakthrough luxury performance sedan called the Infiniti Q45.

Eleven years later two things haven't changed -- constant research into the desires of luxury buyers and Infiniti's dedication to meeting them. The latest examples of this can be seen in Infiniti's enhanced Total Ownership Experience®, announced in June 1996, and the arrival of the new flagship Q45 luxury sedan, which debuts this Fall.

Engine and transmission work together to provide a seamless driving experience. A new 4.1-liter DOHC 32-valve V8 engine provides more torque at low and mid-speed ranges (than the first generation Q45 powerplant), along with reduced weight and improved fuel economy. Horsepower is rated at 266 at 5,600 rpm, while torque is rated at 278 foot-pounds at 4,000 rpm.

Additional improvements in performance and economy are realized by enlarging valve size, changing the cam profile and refining the valve control system. Quieter operation is attained through the use of a large, anti-noise engine cover, a high rigidity aluminum oil pan and a redesigned intake manifold.

The Q's standard four-speed electronically controlled automatic transmission achieves its smooth shift changes through an improved engine/transmission LAN (local area network) system which facilitates more frequent communication between engine and transmission electronics.
