1990-1992 Infiniti M30: Overview

Vehicle Highlights

Complementing the new Q45 "flagship" sedan from Nissan's luxury division was the entry-level M30 coupe, also introduced for 1990. Essentially an Americanized version of the Nissan Leopard, sold in the Japanese market, the M30 was intended as a temporary stopgap, until a brand-new model could be developed. Dimensions were close to the front-drive Nissan Maxima sedan, but the M30 had rear-wheel drive and weighed about 300 pounds more. Maxima provided the 3.0 liter overhead-cam V6 engine, rated at 162 horsepower; but it was mounted longitudinally in the M30, rather than transversely. A 4-speed automatic was the sole transmission. Antilock brakes and a driver's airbag were standard. "Sonar Suspension II," also borrowed from the Maxima, used an ultrasonic sensor mounted beneath the radiator to "read" the road surfaces and adjust shock absorber damping accordingly. A cockpit switch let the driver choose soft, medium, or firm damping mode. Like the bigger Q45, the M30 was marketed as a "one-price" model, fully equipped with only two dealer-installed options available: a cellular phone and a CD player/changer. Standard equipment included a power moonroof, automatic climate control, leather upholstery, power windows and door locks, a 2-way power driver's seat, limited-slip differential, 4-speaker Nissan/Bose audio system, and antitheft alarm.
