The rear-wheel-drive flagship from Nissan's luxury division got a major makeover for 1997. At 111.4 inches, the new sedan's wheelbase was 2 inches shorter than before. Overall length dropped just half an inch, to 199.2 inches. Curb weight dipped from 4039 pounds to 3879, while trunk space shrunk from 14.8 to 12.6 cubic feet. Biggest changes went under the hood, as the previous 278-horsepower, 4.5-liter V8 gave way to a 4.1-liter V8 with variable-valve timing, which developed 266 horsepower. Two versions went on sale: the base Q45 and a Q45t touring edition. Standard on both was a 4-speed automatic transmission, limited-slip differential, antilock braking, dual front airbags, leather interior, and power sunroof. In midseason Infiniti, added side airbags to the Q45.
