there are a couple of additional factors that need to be taken into account. Yes, the base curb weight of the base '18 Equinox is 3,327 pounds compared with 3,764 pounds for its predecessor. But for one thing, the 2018 model is equipped with a 1.5-liter turbocharged engine and the 2017 base model has a 2.4-liter engine, so part of the mass is predicated on having a smaller engine. (Both base models have a Hydra-Matic six-speed automatic, with the new one having a 6T40 and the previous a 6T45.) Then there is an overall dimensional difference: the 2018 Equinox is smaller than the 2017. Specifically: 2018 2017 Wheelbase: 107.3" 112.5" Overall Length: 183.1" 187.8" Overall Width: 72.6" 72.5" Overall Height: 65.4" 66.3" So, when you reduce the size of the vehicle, you do have the opportunity to remove some mass. Evidently, the fact that this is a world vehicle played into the smaller size of the vehicle as well as the use of a smaller base engine. (It should be noted that the Equinox, for the U.S. market, will have an all-turbocharged lineup, with a 2.0-liter gasoline engine and a 1.6-liter turbo-diesel on tap.) One of the changes that they made is to reengineer the rear seats for purposes of improving cargo loading. (Remember: the middle term in CUV and SUV is utility.) When the split rear seatbacks (60/40 split) are folded forward, the bottom seat cushions index forward toward the back of the front seats, thereby allowing the seatbacks to go to a horizontal orientation. While the exterior is smaller, the interior is actually bigger. That is, the passenger volume and maximum cargo volume for the 2017 Equinox are 99.7- and 63.7-ft 3 , respectively. Yet for the 2018, those figures are 103.2-ft 3 for passengers and 63.5-ft 3 for stuff. This capaciousness is the direct result of clever design and engineering. And speaking of the interior, it is worth noting that they've broadened their color palette quite extensively. Mara Kapsis, color and trim designer in the GM Design Studio in Warren, Michigan, points out that they worked to create color combinations (e.g., jet black/brandy; jet black/ cinnamon) that are far from a more mono-color offering. And in addition to materials like leather, they're deploying a denim cloth. walter-tools.com/us The Ikon of a new performance class The Supreme DC170's unique and innovative margin design ensures that the carbide's strength is exactly where you need it; right behind the cutting edge, facing the cutting forces - precisely where greater stability significantly increases productivity. This increases the process reliability, tool life and quality – while simultaneously reducing your manufacturing costs. The Supreme DC170 – The Ikon that gives drilling a new look. Supreme DC170 Visibly different, clearly leading the way. 34 EQUINOX
