The Isuzu Ascender is a mid-size SUV built by General Motors according to a special agreement between Isuzu and this American giant. The vehicle was offered on the U.S. market from 2003 to 2008. Featuring a rear- or four-wheel-drive layout, the Ascender was outfitted with a powerful gasoline 4.2L Vortec I6 or an even mightier 5.3L V8 engine built by GM and available with the only transmission, a 4-speed automatic one. The vehicle itself was a badge-engineered model of the GMC Envoy, yet the Ascender was offered with a better warranty than its GMC counterpart.
