Test Drive:
2002 Infiniti Q45

I once had a racing instructor who said you talk to a car in three ways: with the steering wheel, the brake pedal and the accelerator. “It does not understand oh, sh-t!” he said.

Well, Pierre, I just spent some time with a car that may not understand that particular phrase, but it does take verbal orders…and responds in a female voice. How’s THAT for unusual?

The car is the 2002 Infiniti Q45…a classy, elegant package wrapped around a core of hard, no-nonsense muscle – and it talks Pierre’s version of car-speak eloquently.

This is the Infiniti flagship and while it sails along the highway quietly and smoothly, it is certainly no big ‘boat’. There’s a surprising sense of fun lurking in this vehicle, just waiting to be invited to play a little.

The new third-generation Q is wider than the previous edition and the wheelbase is longer, although over-all length is unchanged at 199.6 inches. Styling is elegant with just a hint that the beauty might be more than skin deep. And those headlights! Night driving is rarely this illuminating. The large, multi-lens projector high intensity discharge (HID) headlights feature seven individual lenses and a free-surface reflector to produce a wide beam of light that lets you see what’s ahead well up the road. Infiniti claims it’s the most powerful headlight system in the world and they might be right.

Inside, the Q carries it’s passengers in high style – everything is covered in rich textures including leather and wood. Infiniti makes a rather surprising statement about the interior. Rather than trumpeting it as a five-passenger sedan, the company says the roomy space is really ‘personal four-seater’.

The driver slides into an ultra-supportive heated leather seat, hands gripping a wood and leather steering wheel. Twist the short-blade electronic key and the large round instruments light up and the Vehicle Information System screen mounted high on the centre stack comes to life. The 5.8-inch VIS screen provides information ranging from climate control and maintenance updates to vehicle settings such as headlight delay, audio settings, navigation display, vehicle electronic systems, language and keyless remote response.

Then, of course, there’s that voice-recognition system, developed with Visteon, which controls the 300-watt Bose audio system and climate controls. Without arguing. But you have to ask nice. Okay. That’s the tuxedo. What about the muscle?

Under the hood lurks a 4.5 litre V8 that puts out 340 horsepower (up from 266) at your beck-and-call. And it answers the call with enthusiasm, drawing on its 333 ft. lb. of torque across a relatively flat rev band. Stomp on the gas pedal and you’re in for a surprise as the big sedan leaps ahead as the new five-speed automatic transmission works swiftly, but smoothly, through the gears. If you like to make the changes yourself, there’s a manual-shift mode to play with.

Corners? Hey, go for it. The Q sticks to the road like it was glued there thanks to a stiffer structure, new suspension and standard vehicle dynamic control (VSC). The front suspension has a new geometry and 5% weight reduction while the new multi-link rear setup is adapted from the Nissan Skyline performance sedan. Rear shocks and springs have been separated to reduce friction by about 40%. If you need to call a sudden halt to all the fun, the four-wheel disc brakes with ABS and brake force distribution will haul you down to a snail’s pace faster than you can say “Who, me, officer?”

If I had the necessary 73 big ones to spend, I’d join the Q queue. No question.
