When will New Tahoe, Suburban and Yukon launch? We can’t wait! GM reveals more fuel economy numbers on it. It’s more economical.
GM has revealed more information on its all-new 2021 full-size SUVs, with towing and fuel economy numbers on the Chevrolet Suburban and Tahoe, and GMC Yukon and Yukon XL. For the most part, they’re fairly close to the outgoing models, but while fuel economy improves for city driving, it takes a slight dip on the highway.
GMC had earlier introduced the Yukon to the press at an auto-show-style reveal in Colorado in January. The top-trim Denali will become a sub-brand, with special exterior styling cues and unique interior. In Canada, about 60 per cent of Yukon buyers opt for the Denali trim.
As with the current model, the 2021 Chevrolet and GMC sport-utes will come with a 5.3L V8 making 355 horsepower and 383 lb-ft of torque; or with a 6.2L V8 spinning out 420 horses and 460 lb-ft of torque. Both use Dynamic Fuel Management (DFM), which shuts off cylinders in a variety of patterns for better fuel economy when full power isn’t needed. The 5.3L currently comes with a six-speed automatic transmission, but for 2021 will upgrade to the ten-speed automatic that’s mated to the 6.2L.
Also available will be a 3.0L inline-six turbodiesel, making an estimated 277 horsepower and 460 lb-ft of torque and with the ten-speed. Towing and fuel figures haven’t been released yet.RELATEDFirst Look: 2021 GMC YukonChevrolet will delay Corvette trim, new Suburban over COVID-19: report
GM released U.S. fuel figures, but in Canadian equivalent, the 2021 Tahoe with 5.3L gets 14.7 L/100 km in the city and 11.7 on the highway, both in 4×2 and 4×4 configuration. The 2020 model is thirstier in the city at 15.6 L/100 km, but better on the highway at 10.6 L/100 km.
In 4×2 configuration, the 2021 Suburban with 5.3L is similar. In 4×4, it rates at 15.6 L/100 km in the city and 12.3 on the highway, compared to 16.8/11.2 for the 2020 version.
With towing, it all depends on what model you choose — and while some can tow more than before, others don’t have quite as much grunt.
Straight out of the box, the 2021 Tahoe’s maximum towing capacity ranges from 7,600 to 7,900 lbs, while the 2020 model went from 6,400 to 8,100 lbs. The 2021 Suburban ranges from 7,500 to 7,900 lbs, while the 2020 model pulls between 6,000 and 8,100 lbs.
Equipped with a maximum towing package, the 2021 Tahoe’s top capacity is 8,400, down from a high of 8,600 lbs in 2020. Similarly-equipped, both the 2020 and 2021 Suburbans have a top capacity of 8,300 lbs.
Just when the 2021 models will hit showrooms is anybody’s guess, due to the COVID-19 pandemic shutting down assembly lines. GM had planned to debut the all-new, all-electric Hummer pickup and SUV on May 20 but has postponed it, while the refreshed Chevrolet Equinox and Traverse, planned for 2021, have now been rebadged as 2022 models.
