REVIEWS AND ROAD TESTS

The best is yet to come

GM reacted forcefully to the Ford F and Dodge Ram models, not only by redesigning its big trucks, but by giving them a name that’s more inspired and expressive than the form C and K appellations. And so the GMC Sierra is easier to recognize, although the Chevrolet Silverado has the same front-end treatment as the previous generation. But all comparison ends right here, since both these vehicles have changed almost completely, save for a few mechanical features such as the base V6 engine. Also noteworthy are the new 4.7- and 5.-3 liter V8s, with a cast-iron block and aluminum cylinder heads, based on the V8 used to power the latest Corvette C5 and the Camaro. Furthermore, they’ve become more powerful for 2000. There’s an even sturdier version, the 6.0-liter, which is, however, available only on the 2500 series. Also entirely revamped is the chassis and the optional AWD system. These GM trucks are available in regular cab or four-door extended or crew cab versions, either with a short bed or with the now familiar long bed.The interior is much more appealing than it used to be, seats are more comfortable and several different configurations are possible. Access to the rear of the extended cab model is made easier with a panel that opens on the right and on the left. The dashboard, also very modern- looking, houses very easy-to-read instrumentation, but GM has decided to stick with the concept of positioning windshield wiper controls, speed governor and signal light controls all on the same arm, which leads to confusion. In passing, note that visibility on board is excellent.The more powerful V8s that power these trucks are impressive because of their performance capabilities, because of handling that is steadily approaching typical automobile- type handling and by the smoothness of manoeuvres, even in 4×4 mode on bumpy roads. Of course, the stiffer the suspension (for more loading capacity), the more feedback occupants get on poor road surfaces, but this is no big deal. Some whistling caused by the rush of air over the curve of the windshield disturbs the otherwise quiet ride.

The AWD Autotrac version works like a traction control system. Another interesting characteristic is the automatic transmission, available on GM trucks with a Tow/Haul function that when activated can stretch its speeds and delay shifting to make acceleration easier.
