Chevrolet's 3.4-liter unit is an old pushrod-overhead-valve design that lacks modern features such as variable valve timing and variable-length intake runners (although it does feature hydraulic roller lifters, just like a Corvette). It feels strained when pushed at high rpm. Still, Equinox delivers good acceleration under most circumstances, and it's smooth enough. EPA fuel economy estimates are improved somewhat for '07, at 19/26 mpg city/highway for front-drive models and 18/25 for the AWD version.
The V6 engine is aided considerably by the five-speed automatic transmission. Chevrolet says the Equinox can accelerate from 0 to 60 mph in about 8.5 seconds, which should be adequate performance for most families. And while it may not excel at acceleration, Equinox is rated to pull a 3500-pound trailer, the same as the more powerful Escape and RAV4 V6s.
Its long wheelbase and 3800-pound heft give the Equinox a decent ride, making it a suitable companion for long trips. Its handling is responsive and it's easy to modulate the brakes for smooth stops.
The Equinox has good road feel in highway driving, yet steering effort is low at low speeds for easier maneuvering in tight parking lots. The steering ratio is variable, and the Equinox uses electric, rather than hydraulic, power steering. We don't think the average driver will feel the difference between this system and more conventional hydraulics, and that's a good thing. Unlike a hydraulic servo, the electric booster doesn't use engine power, resulting in slightly better fuel economy.
StabiliTrak electronic stability control helps drivers maintain control during sudden maneuvers or in low-traction conditions by using a comprehensive series of sensors to measure acceleration, deceleration, steering angle and yaw rate. The system steps in when the Equinox doesn't seem to be going where the driver intended. When that happens, StabiliTrak regains control by regulating acceleration or applying the brakes at individual wheels, a feat no driver can perform.
All-wheel drive improves stability on wet pavement, which makes it a valuable safety features. The system still sends the power to the front wheels in normal conditions on dry roads; it automatically transfers power to the rear wheels only if the front wheels slip.
The optional navigation is integrated into the audio system for 2007.
OnStar is an economical alternative to a full-featured navigation system. All Equinox models with OnStar now include a service called Turn-by-Turn Navigation. Turn-by-Turn allows consumers to talk to a live adviser, who sends complete step-by-step audio directions, as needed, through the vehicle's stereo. The directions are triggered by the OnStar system's GPS capabilities. This enables drivers to find their destination while keeping their hands on the wheel and eyes on the road. OnStar is also an excellent safety feature, as its operators will dispatch rescue crews to the scene should your airbags deploy and you fail to respond to their calls. OnStar always knows the location of your vehicle. Simply press the blue button and a human operator responds, to provide directions and other assistance. They can unlock your doors if you lock your keys inside. They can direct you to the nearest gas station or help find a good restaurant or motel. If your vehicle is stolen, OnStar can pinpoint its location and direct the authorities to apprehend and recover.
XM Satellite Radio is another great feature, especially when traveling cross-country, because the stations don't change. It's nice to have around town for listening to music, 24-hour news broadcasts (Fox News, CNN), sports (NASCAR), talk radio, and comedy.
