2021 Chevy Tahoe, GMC Yukon fuel economy and towing capacities go official

Most of the puzzle pieces have fallen into place with GM’s new full-size SUVs, but today we have fuel economy and towing to add to the picture. Numbers for the standard 5.3-liter V8 and upgrade 6.2-liter V8 are out, but GM has held back on the 3.0-liter turbodiesel inline-six for the time being. Those numbers are most likely not ready yet. Minor improvements and decreases are seen throughout the Tahoe/Suburban and Yukon/Yukon XL lineup. Because there are so many variants, weÂ’re going to just lay them out below for you. 5.3-liter V8 2021 Tahoe/Yukon 2WD: 16/20/18 2021 Tahoe/Yukon 4WD: 16/20/18 2021 Suburban/Yukon XL 2WD: 16/20/18 2021 Suburban/Yukon XL 4WD: 15/19/17 6.2-liter V8 2021 Tahoe/Yukon 2WD: 15/20/17 2021 Tahoe/Yukon 4WD: 14/19/16 2021 Suburban/Yukon XL 2WD: 15/20/17 2021 Suburban/Yukon XL 4WD: 14/19/16 As you can see, there isnÂ’t a whole lot of difference between two-wheel drive and four-wheel drive options. You can eke out an extra mpg here and there, but itÂ’s a penalty weÂ’d be happy to live with to have four-wheel traction. The biggest loser in all of this is highway mpg. Chevy has made the trucks bigger and added weight with the independent rear suspension, causing a decrease in fuel economy. For example, a 2020 Tahoe with the 6.2-liter V8 and four-wheel drive is rated at 14/22/17. The 2021 truck drops 3 mpg on the highway and 1 mpg in the combined rating. There are improvements to be found, though. A 2020 Suburban with the 5.3-liter V8 and four-wheel drive is rated 14/21/16. Fuel economy in the city goes up 1 mpg, but you lose 2 mpg on the highway and 1 mpg in the combined rating. ThereÂ’s a bit of give and take here, but at least a slight increase in city mpg has accompanied the greater loss in highway fuel economy. 2021-chevy-tahoe-chicago-01 View 12 Photos As for towing, the Tahoe/Yukon with the 5.3-liter V8 and two-wheel drive has a new 7,900-pound capacity, and the four-wheel drive model is rated at 7,700 pounds. Respectively, those are the best figures youÂ’ll get with the standard towing capacity. Opt for the maximum towing package, and the Tahoe/Yukon capacities go up to 8,400 pounds (two-wheel drive) and 8,200 pounds (four-wheel drive). The numbers all take slight cuts when you go for the 6.2-liter V8. Both the Suburban and Yukon XL offer similar or identical towing figures as their shorter counterparts do.

2024 GMC Sierra HD prices start at $46,295, increasing $100 to $2,500

After an online reveal in October of last year, prices for the 2024 GMC Sierra HD have crept online thanks to GM Authority. The upscale heavy duty pickup gains a new-look design and a more powerful turbodiesel V8 that boosts the tow ratings every HD buyer likes to keep up their sleeves like aces. The optional 6.6-liter turbodiesel Duramax V8 increases horsepower 25 ponies to 470 and torque by 65 twists to 975 pound-feet, both numbers matching the 2024 Chevrolet Silverado HD's diesel output. The torque comes with more useful delivery as well, GMC saying it increased low-end twist by about 25% thanks to a new turbocharger. Buyers who go for the 6.6-liter gas V8 will command 401 hp and 464 lb-ft. Both engines run output through a ten-speed automatic. One the gasser, the new gearbox replaces a six-speed auto. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), the 3500 HD capable of towing up 36,000 pounds. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic and Downpour Metallic. Configuration variables include Regular, Extended and Crew cabs, and Pro, SLE, SLT, AT4, AT4X, Denali and Denali Ultimate trims. The AT4X is late availability, the Denali Ultimate is new for 2024. The Denali Ultimate comes with the 6.6-liter turbodiesel V8, a trim-specific grille, 20-inch machined-aluminum wheels with high-gloss black accents, power-operated running boards, leather upholstery, wood interior trim, massaging front seats, a Kicker sound system and exterior emblems featuring Alaska's 20,310-foot Mount Denali.  Pricing is up by $100 to to $2,500 depending on trim.

Next GMC Sierra Denali accidentally leaked on consumer site

Thanks to the quick-to-screen-shot folks at GM Authority, we now have our first look at what is likely the 2014-15 GMC Sierra Denali. GMA reports that the image you see here was temporarily posted on the GMC consumer site, though as you can see now, when you scroll over the "trucks" tab, the image has been removed.
GM Authority states that because the truck in this image wears a blacked-out lower bumper, redesigned grille insert and shiny wheels, this has got to be the upmarket Denali version of the fully redesigned 2014 model year Sierra. The Chevrolet Silverado will be getting a similar treatment, as we've seen in recent spy shots, dubbed the High Country.
Expect the Sierra Denali to ride on large, unique wheels (the one we spied earlier this year was fitted with 21-inch rollers), and feature a huge helping of luxurious interior amenities, as well as premium features like xenon headlamps. An official on-sale date for the Denali has not been released, though it's been reported that the high-grade Sierra, along with its Silverado counterpart, will arrive after the Texas State Fair this summer.
