One should pay heed any time a manufacturer states that its product has a "very firm ride." It's safe to assume they really mean it and, in the case of the ZR-2, that assumption would be correct. The wheels may be aluminum, but there's a lot of weight in the rubber. Firm springs keep the suspension from bottoming in the outback, but they also pass along every dimple and bump on the road. Firm shock absorbers keep the unsprung wheel-and-tire mass in check, but relay every bump in the road. The big 31x10.50R15 BF Goodrich Radial All-Terrain T/As take on an inertial life of their own; the driver can always feel those tires, reacting to bumps, bouncing with undamped sidewall flex, and generally doing their own thing. Going around corners on pavement, the ZR-2 exhibits heavy understeer at the limit. Despite the power steering, hustling down a winding road is a lot of work. The gnarly tires have a lot of void, but they're still fairly grippy on pavement. Apply too much power, particularly on slick or dusty pavement, and the rear end will come scooting out. Because the four-wheel-drive is a part-time system, it will not provide handling assistance like a full-time system. Of course, to a real truck driver, a full-time system would be effete. Real men (and real women) can switch their own 4wd on and off, even if by button instead of by lever and even if there are autolocking hubs that don't require one to get muddy knees to manually lock each front hub. That, son, is progress. The engine definitely provides enough torque. At idle it rolls out the tailpipe in a ringing metallic bass, and roars at full throttle all the way to the 5100-rpm redline where it lunges ahead to the next gear. It's happiest at lower rpm where the ZR-2's torque assures that it's no sluggard. Out on the highway, the engine is reasonably quiet-or at least isn't noticeable over the road noise. The same tires that affect the ride also make a fair amount of noise. Although they don't whine like the mudders of yore, the knobs can't help but make their presence known. Of course, judging the ZR-2 pickup like a Lumina sedan isn't exactly fair-unless you also take the Lumina into the woods. And there the ZR-2 leaves the Lumina hung up and high centered. In the dirt, with the transfer case in 4x4, the ZR-2 will go places seemingly impossible, climbing hills, traversing ravines and scrabbling over rocks. Here the unsprung mass isn't the disadvantage it is on the road, because at the slower speeds you should be driving in the rough, the weight has time to react. The tread that's less than ideal on the highway is perfect for gripping the dirt. The automatic transmission makes the going easier in the dirt. It's tough enough to take the shock loading that off-roading can dish out and eliminates the worry about slipping the clutch into oblivion. Shifting between two- and four-wheel drive can be done on the fly; stopping isn't necessary. Four-wheel-drive low range is only a button's push away, though, like all such systems, it requires stopping and putting the transmission into neutral to engage. On road or off, the ZR-2 has one exceptional talent: Getting itself dirty. The flares do only a limited amount of good. The first muddy puddle provides all the ammunition needed to bespatter the flanks--and even the side windows. |
