Antilock brakes are standard on all versions of the Equinox for 2006. This is a smaller, less expensive midsize-SUV companion to Chevrolet's TrailBlazer. It shares its car-type architecture and powertrains with the Pontiac Torrent. Equinox seats five. The rear seat slides fore and aft 8 inches to adjust for passenger or cargo space. The rear liftgate does not include opening glass. LS and uplevel LT trim are offered, both with front-wheel drive or AWD without low-range gearing. A 185-hp V6 and 5-speed automatic transmission is the sole powertrain. Traction control is standard on 2WD versions. ABS and traction control are now standard on all models; they had been optional on the 2WD LS. Curtain side airbags are optional. Available features include leather upholstery, heated front seats, and OnStar assistance.
