No.
1990 Infiniti Q45 7.2 15.4
The new Q is fastest at highway passing speeds. 60-80 mph runs+, due to it's taller gearing. 2003+ models will actually be slower at those higher speeds.

This is a good read from a link I saved on the 02 Q45:
At the Phoenix International Raceway track on the 11-turn 1.5-mile road course, the fastest times can be achieved with the VDC system switched off. And the new Q is fast, very fast. The course setup uses the front and back main straightaways, with turn 10 and 11 being the high banked oval. When leaving the starting line on pit row, smoking the tires was easy and the Q accelerated to about 70 mph in about an eight of a mile until the left turn in for turn 1, which leads almost immediately to a decreasing radius turn 2, which could be best handled by cranking in steering and using throttle to get the rear end out. From turn 2 were three quick chicanes, which almost could be steered by the new Q as a short straight with full throttle accelerating the car to about 75 mph until arriving at turn 6, which is a sharp, almost hairpin, decreasing radius corner that required the slowing of the Infiniti to about 40 mph and then getting on the gas half way through and getting the rear end out, exiting at about 60 mph. On the track (or in city traffic) big, powerful brakes make a difference. In racing, he who brakes last is many times the fastest and that takes real confidence in the brakes, knowing you can go a little deeper into each corner.
The Q uses ventilated discs at all four corners with twin pistons up front, ABS and EBD. They never faded or got mushy during 20 or so laps. The more laps, the more confidence. Turn 6 leads to a sweeping right-hander with blips called 7 and 8, which can be driven as a short straight in the Q until reaching turn 9, which is a 180-degree hairpin that requires slowing the car down from about 82 mph to about 35 mph in what appears to be not much more than 150 feet. Half way through the hairpin, you get on the gas to accelerate down the main track's back straight, which is really the second half of the tri-oval, to about 85 mph until the lefthand oval banked turn 10, which used cones to keep some wannabe Jeff Gordons away from rubbing the wall. Consequently, the car stayed low on the turn, maintaining about 85 mph through the turn10 and 11 until the apex of turn 11, when you could get on the gas for the run down the front straight, reaching about 105 mph until heavy braking hauls the Q down to about 70 mph for the left turn in for the road course and turn 1.
Fast times require smoothness and the new Q makes being smooth about as easy as taking a nap at a library convention. Steering has perfect feel and the suspension hangs on like an out-of-work brother-in-law using your spare bedroom. It just doesn't want to let go unless you really push it. With the VDC switched off, getting the rear end out and throttle steering was a blast. With the sport package, you get 18X7.5-inch eight-spoke alloys and 245/45ZR performance radials, which give you nearly 10 inches of footprint from each tire -about double the size of the shoes that Shaq wears. Passing tests from 50-70 averaged 3.28 seconds.
