Consumer Guide® Road-Test Evaluation

Unstressed in everyday driving, the Ascender delivers acceptable acceleration. Test regular-length six-cylinder Ascenders did 0-60 mph in 8.8 seconds. Seven-seat versions weigh about 350 pounds more. In them, the six-cylinder is still adequate, but a V8 adds useful muscle for hauling or towing heavy loads. As for gas mileage, test regular-length Envoys and Ascenders have averaged 12.1 to 17.4 mpg. An extended-length 2WD six-cylinder Ascender averaged 12.1 mpg in all-city driving. A V8 model logged 15.2 to 15.7 mpg. GM claimed Displacement on Demand improved mpg by up to 8 percent in certain light-load driving conditions. The Ascender's suspension absorbs bumps quite well for an SUV, extendeds better than regular-length. Without the air suspension available on GMC's Envoy, though, these Ascenders also porpoise through dips and swells. Handling is disappointing overall, with considerable body lean in sharp turns. Steering has vague feel and demands a lot of correction at highway speed. A relatively tight turning radius makes close-quarters maneuvering fairly easy. Standard antilock four-wheel disc brakes deliver adequate stopping power, but quick stops trigger marked nosedive and some wander. Optional traction control on 2WD models has worked well in snow. Wind rush can be considerable at highway speeds; there's roar even around a closed sunroof. The six-cylinder engine cruises quietly enough, but sounds gruff when cold and a touch ragged at full throttle. The V8 is quieter overall. Controls are clear and handy. Switchgear works smoothly, but adjusting the low-mounted climate controls forces a long look away from the road. Front-seat head and leg room are good, even for taller folks. Seats are too soft for optimal support, but not uncomfortable. Visibility is restricted aft and over-the-shoulder by headrests and thick roof pillars. Available power-adjustable pedals could be helpful, especially to shorter drivers. Six-footers have plenty of second-row head room. Rear knee room is adequate in regular-length versions, ample in extended, and both have adequate under-seat foot space despite an uneven floorboard. The split bench seat is comfortable, fairly supportive, and wide enough for three adults with a little squeezing. With seven-passenger seating, second-row seats slide forward and tilt up for accessing the third-row seat, which is roomy enough for two adults and more comfortable than those in most midsize SUVs. Cargo space is generous in regular-length Ascenders, spacious in extendeds. The 60/40 split seat folds easily, helped by automatic-folding headrests. However, instead of a flat load floor with all seats folded, Ascender has a tiered floor that frustrates easy loading and packing. The liftgate's separate-opening glass is relatively high, making it difficult to load some items. Cabins have a good array of pockets and compartments for small items.
Value for the Money
Though Ascenders match most rivals for pace and space, Isuzu's longer warranty doesn't fully compensate for a spotty dealer network. Additionally, Isuzu's financial woes put the company's future in doubt, especially since Ascender is the only model that remained after 2005. Shoppers considering Ascender would do well to ponder the similar GMC Envoy instead.
