Equinox debuts for 2005 as a smaller, less-expensive midsize-SUV companion to Chevrolet's TrailBlazer. It shares its car-type platform with the Vue from GM's Saturn division, but has a longer wheelbase and body, and has steel body panels in place of Vue's plastic. Equinox seats five; no 3rd-row seat is offered. The rear seat slides fore and aft 8 inches to maximize passenger or cargo space. The one-piece rear hatch does not include separate-opening glass. Equinox comes in LS and uplevel LT trim, both with front-wheel drive or all-wheel drive without low-range gearing. A 185-hp V6 and 5-speed automatic transmission make up the sole powertrain. Traction control is standard on the 2WD LT, optional as part of the ABS option on the 2WD LS. ABS is standard on all but the 2WD LS. Head-protecting curtain side airbags are optional. Available features include leather upholstery, heated front seats, satellite radio, OnStar assistance, and 17-inch wheels in place of standard 16s.
