Isuzu's biggest and most powerful SUV ever

In the sport-utility vehicle field, model names tend to last a while. Still, not many have hung on as long as the Trooper, which first appeared at Isuzu dealerships back in 1984. Finally, soon after the start of the 2003 model year, Isuzu has a brand-new replacement just about ready for sale. Named the Ascender, the seemingly full-size SUV was first unveiled at the New York Auto Show in March 2002. Isuzu's biggest and most powerful model ever, it's also claimed to be the only SUV in its class with a 10-year/120,000-mile powertrain warranty.
Built on an extra-long (129-inch) wheelbase, the Ascender stretches to 207.6 inches overall.
Again truck-based, with separate body-on-frame construction, the Ascender differs from the departed Trooper in that it's not strictly an Isuzu design. This time, the foundation stems from General Motors. The Ascender's platform is essentially the same as the one used for the Chevrolet TrailBlazer EXT and GMC Envoy XL—two extended-length midsize models that debuted during the 2002 season. All three SUVs, in fact, are produced at the same GM factory in Ohio.
Though officially midsize, this is one big vehicle. Built on an extra-long (129-inch) wheelbase, the Ascender stretches to 207.6 inches overall. Though it was considered a full-size SUV, the Trooper was only 187.8 inches long, on a 108.7-inch wheelbase.
Glancing back from the driver's seat, the Ascender's interior looks virtually cavernous—if anything, even more van-like than its Chevrolet and GMC counterparts. For owners who intend to haul a full load of passengers and cargo, that's a bonus. Seating for seven occupants is standard, and each can expect plenty of space to stretch out. Isuzu advises that cargo capacity rivals that of larger SUV models.
Both the LS and the Limited include GM's OnStar emergency/communications system and a Travelnote voice recorder.
Also unlike the Trooper, which used V-6 power, the Ascender comes with a choice of two engines: inline six-cylinder or V-8. The 4.2-liter six produces 275 horsepower and 275 lb.-ft. of torque. Optional on the LS and Limited, the 5.3-liter V-8 generates 285 horsepower and a more compelling 325 lb.-ft., which is enough to permit a towing capacity of up to 7,400 pounds. Constructed of aluminum, the V-8 is said to weigh 100 pounds less than an equivalent engine with a cast iron block.
