Fitment of the 2.4-liter EcoTec direct-injected four will give the Equinox an estimated 30 mpg highway, impressive numbers even for a small SUV (and this platform is more like a mid-size at least in terms of weight). The powerplant will yield 180 hp and 172 pound-feet of torque due to an 11.4:1 compression ratio and special dished pistons.
The Equinox will also feature a 3.0-liter direct-injected V-6, based on the 3.6-liter "high feature" V-6 powering Cadillacs and crossovers. This unit cranks out 255 hp and 217 pound-feet, but GM has not yet provided estimates for its fuel efficiency.

Why do I make an issue of this? Because this is expensive, arguably unnecessary technology, the kind that GM bean counters have been poo-pooing for decades in search of higher profits. I think it's significant that they are replacing the old Equinox powerplant, an entirely adequate -- yet antediluvian -- push-rod V-6, with this thoroughly modern powerplant that simply blows it away on every level. GM draws 180 horses, only five less, from a package that is over 40 percent percent smaller than the outgoing V-6. It will also beat the outgoing model by a whopping 6 mpg on the highway.
Investment in technology and good products, not smoke and mirrors badge engineering, will hopefully take GM through the dark night of this economy. Kudos, and keep it up.
