One of the secrets to the big weight loss? Glue. Many of the steel parts of the Acadia’s underbody are held together not by rivets or welds but by advanced adhesives similar to those used in modern airplanes like the Boeing Dreamliner. Since the glue bonds parts together all along the seam where they connect, not just in certain spots, the parts become stiffer. Because of the stiffness, General Motors is able in many cases to switch to thinner steel, helping the new Acadia shed pounds. The grades of steel are thinner by only about the width of a human hair, but “it’s all the little things that add up to the big number,” said Charlie Klein, executive director of GM’s global carbon-emissions reduction strategy. Automakers are racing to improve fuel efficiency to meet the increasing mileage standards that environmental regulators have set for the next nine years. Space-age adhesives are being used more widely, just one of the many leaps manufacturers are taking to reduce weight and save fuel. But to continue their gains, automakers must find additional innovations. One promising technology on the horizon is a new type of gas-electric hybrid that draws power from a 48-volt battery ... The 48-volt battery drives an electric motor that gives the engine an extra 20 or so horsepower, cutting fuel use in starts and acceleration ... ... the 2025 target ... a bid to battle climate change ... Automakers and regulators are at odds ... Automakers agree that electric cars offer impressive fuel-economy numbers but counter that consumers buy too few of them to move the average number ... ... automakers are hoping for advancements from a new wave of innovations. They include: — Stop/Start ... — Freewheeling Also known as engine-off coasting, this lets an engine shut off momentarily while a car is coasting, reducing fuel consumption. A hybrid car can use its electric motor to maintain cruising speed, letting the engine remain off longer. — New Materials ... — Cylinder Deactivation ...
