The Equinox is the first crossover SUV from Chevrolet, marketed by GM as a compact SUV. Riding on GM's Theta platform, the unibody Equinox is mechanically similar to the GMC Terrain, Saturn Vue, Pontiac Torrent, and the 2007 Suzuki XL7. However, the Equinox and the Torrent are larger than the Vue, riding on a 112.5 in (2,858 mm) wheelbase, 5.9 in (150 mm) longer than the Saturn. Front-wheel drive is standard, with optional all-wheel drive. The Equinox is not designed for serious off-roading unlike the truck-based Chevrolet Tahoe and Chevrolet TrailBlazer. For the 2006 model year, GM updated the Equinox for the first time, as GM badges were added on the front doors.
The Equinox is produced at the CAMI Automotive GM/Suzuki joint venture plant in Ingersoll, Ontario, Canada. The 3.4 L LNJ V6 engine is made in China (by Shanghai GM), while the Aisin AF33 automatic transmission is made in Japan. Starting with the 2008 model year, the Equinox Sport was available with a 3.6 L V6 engine that was made in the United States.
In 2008, Chevrolet added a Sport model of the Equinox that features lowered ride height and the new 3.6 DOHC V6. The larger, more powerful (264 hp (197 kW) or 40% increase) engine allowing acceleration from 0 to 60 mph (97 km/h) in under seven seconds. The Sport model received a slightly different exterior styling, 18 inch wheels and a six-speed automatic transmission. It was available in either front-wheel drive or all-wheel drive configurations. GM stated the Equinox Sport was the first vehicle to reflect its more cautious naming standards. Instead of using the Super Sport badge as it had in the past on higher performance vehicles (such as this one), GM opted to reserve the SS nomenclature for special models worthy of its namesake.
Changes to 2008 Equinox models included the relocation of the compass readout from the inside rearview mirror to the driver information center (on models so-equipped), and three new exterior colors: Navy Blue Metallic, Black Granite Metallic, and Golden Teal Metallic.
OnStar was standard on the 2008 Equinox. This system included for Turn-by-Turn Navigation, the first factory-installed, fully integrated GPS navigation system from OnStar. The 2008 models included an enhanced ride and handling package with stiffer shocks, bushings, and tuned spring rates. Four-wheel disc brakes with ABS and tire pressure monitoring system was standard.
An Electronic Trailer Sway Control was introduced that integrated into the standard StabiliTrak system. This can detect the occurrence of trailer sway that may be caused by improper trailer weight balance or excessive vehicle speed. If the trailer begins to sway, StabiliTrak will apply brakes individually, independent of the driver controlling the brake pedal, to assist stabilizing the vehicle. Under these conditions a light will flash to signal the driver to reduce vehicle speed. If trailer sway continues, the system will reduce engine torque to reduce the speed of the vehicle. Head curtain side air bags were optional.
