Kiera Shaw. GMC. October 24th , 2017.
Also available is the all-new 2.8L Duramax turbo-diesel, which includes a maximum trailering rating of up to 7,700 pounds (3,493 kg) and EPA-estimated fuel economy of 31 mpg highway (2WD). It is the cleanest diesel truck engine ever produced by General Motors and meets some of the toughest U.S. emissions standards, thanks in part to a cooled exhaust gas recirculation system. The engine is paired with the Hydra-Matic 6L50 six-speed automatic transmission, which uses a unique Centrifugal Pendulum Vibration Absorber in the torque converter to reduce powertrain noise and vibration. Diesel models also feature smart diesel exhaust braking and an integrated trailer brake controller. Smart diesel exhaust braking enhances vehicle control and reduces brake wear by varying the amount of brakes needed for the vehicle, load and grade. The integrated trailer brake controller system works with the anti-lock brake system to provide immediate and measured brake force with the electronically controlled trailer brake system.
"The new Acadia captures a greater feeling of refinement, in everything from the responsive feeling behind the wheel to the way passengers interact with its intuitive features," said Rick Spina, executive chief engineer for compact and crossover SUVs at General Motors. "It a vehicle that offers the functionality Acadia is known for, while delivering big advantages and balance to customers everyday lives." The new GMC Acadia is 700 pounds lighter than the current model, which pays dividends at the gas pump. A new, 2.5L engine is standard, offering an estimated 28 mpg on the highway for FWD models (EPA estimate not yet available; estimate is based on GM testing). City fuel economy offered is GM-estimated at 22 mpg (FWD) and is bolstered by GMC first application of Stop/Start technology, which enhances efficiency in stop-and-go driving.
The all-new Yukon family is more powerful and efficient than before, thanks to the new EcoTec3 engine family, which debuted earlier this year in the all-new 2014 Sierra. A 5.3L V-8 is standard in Yukon and Yukon XL models and an exclusive 6.2L engine is standard in Denali models, which is expected to deliver the segment best horsepower and torque. The EcoTec3 engines feature state-of-the-art technologies, including direct injection, cylinder deactivation, continuously variable valve timing and an advanced combustion system, designed to make the most of power, torque and efficiency across a broad range of operating conditions. More precisely controlled combustion enables the new engines to run with a higher compression ratio, which delivers greater power and efficiency.
Bold styling and advanced technologies - including new safety and security technologies - support Yukon greater capability, while a more comprehensive list of standard features and enhanced infotainment options are designed to broaden the appeal of one of the industry most-popular full-size SUV lineups. Combined Yukon/Yukon XL and Denali sales were up 24 percent for the eight months of 2013. "Weve engineered the Yukon and Yukon XL from the ground up, building on a strong legacy of capability to take them to the top of the segment with exceptional refinement and purposeful technology," said Tony DiSalle, vice president of GMC Marketing. "And when it comes to the tasks people rely on a full-size SUV for, they do it better than ever - and with more style."
