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.

Chevy confirms 2016 Camaro will have wheels, brakes

Good news, everyone! Chevrolet has issued yet another round of teaser images and information about the sixth-generation Camaro, set to debut in Detroit on May 16. This time around, Chevy's teaser images confirm that the new car will not only have wheels and tires (Goodyear Eagle F1s, no less), but brakes as well. On top of that, we now know that the new Camaro will be 28-percent stiffer than the outgoing model. "The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly," GM said in a press release, which you can read below. We've already learned that the new coupe will be 200 pounds lighter than its predecessor, has a bunch of unique parts, and according to GM's Mark Reuss, will outperform the Ford Mustang in every way. Now, it's only a matter of time before we see the sixth-gen Camaro, but surely not before Chevy issues even more teasers and information.

The structural modeling led to the Gen 6 Camaro being 28 percent stiffer than the current model. "The modeling abilities of computer aided engineering are advancing at incredible rates," said Jim Karlavage, Camaro program engineering manager. "Today, we can accurately model opportunities to add torsional strength without adding unnecessary mass. The result is a lighter, stiffer structure that benefits every aspect of the driving experience." The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly. "The structural weight savings are compounded by opportunities to reduce un-sprung weight," said Karlavage.

2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Mich. "Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range," said Larry Nitz, executive director of GM global transmission and electrification engineering. "Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.
