From Infiniti press: The renowned Infiniti Q45 marks its tenth year of production in 1999 with a long list of enhancements designed to keep the flagship of the Infiniti line on the leading edge of the luxury performance sedan class.
The changes for the new model year range from revised front and rear exterior styling to new comfort and convenience amenities, along with a new electronically modulated suspension with driver selectable settings and 17-inch wheels and tires for the sporty Q45 Touring Package model (Q45t).
The Q45’s standard 4.1-liter 32-valve DOHC V8 remains one of the most advanced designs in its class. The engine was developed to meet the everyday demands of around town driving, including responsive acceleration, smooth and quiet operation and low maintenance, yet still appeal to performance minded drivers as an exceptional higher speed tourer when the call of the open highway beckons. The Q45 also delivers responsible fuel economy of 17 mpg City / 24 mpg Highway.
The engine, rated at 266 horsepower and 278 ft-lbs of torque, is mated to an advanced electronically controlled 4-speed automatic transmission. A viscous limited-slip differential is also standard on every Q45, along with Infiniti’s Traction Control System (TCS). TCS provides excellent all-condition driving performance, automatically engaging when any one of the ABS wheels are slipping to enhance stability and control.
The Q45’s refined suspension utilizes front MacPherson struts with coil springs and is designed to enhance handling and stability by minimizing camber change during cornering. The rear suspension is an independent multi-link design, using three links (instead of the typical two-link design) to provide maximum tire contact with the road and superior body roll control, even under extreme driving conditions.
