www.ADandP.media AD&P; ∕ OCTOBER 2017 CHEVROLET TRAVERSE Traverse is the new chassis and suspension. He says that one of the issues with developing a suspension setup for a vehicle like this is to provide a sweet spot between having an isolated ride yet good handling. Realize that this is a big vehicle, and in addition to the aforementioned dimensions, know that the Traverse has a curb weight of 4,362 pounds. Up front: MacPherson strut independent with hydraulic control arm ride bushings and hollow stabilizer bar. There is an isolated cradle. ZF pre-loaded valve (PLV) passive dampers with rebound springs. In back: Five-link independent setup. Uses an isolated rear cradle with a hydraulic forward mount. There are cross-axis ball joints and a hollow stabilizer bar. There are ZF PLV 18/36 shocks. And there are newly-developed (patent pending) auxiliary spring aids. While on the subject of ride and handling, there are an electric variable-effort power steering system with active return assist and four-wheel-disc brakes with power assist (using Duralife rotors, which have a hardened and strength- ened surface to reduce corrosion). MASS EFFICIENT About that aforementioned curb weight. Perelli points out that the body-in-white of the 2018 Traverse is actually 111 pounds lighter than its predecessor and the overall vehicle mass is down by 362 pounds. A big contributor to the weight-save is the use of high- strength steels. The percentage of stamped steel usage by mass: • 36 percent dual-phase and multi-phase steels • 20 percent high-strength, low-alloy steel • 17 percent bake-hardenable steel • 7 percent martensite and press-hardened steels • 20 percent mild steel In terms of the vehicle body and structure, there is no aluminum used; it is all steel. Perelli also says that in addition to welding, there is 120-feet of adhesive used to help create a stiff body structure. Perelli: "The mantra we had when developing this vehicle: 'No Compromise.'"
