GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

Hertz and GM team up to put 175,000 rental EVs on the road

Hertz and General Motors have announced a significant partnership that will send up to 175,000 electric vehicles into rental fleets across the country. The deal will unfold over the next five years and include vehicles from all GM brands.   The partnership will run through 2027. Hertz estimates that the electric fleet can save as many as 8 billion gasoline-powered miles, removing 1.8 million metric tons of carbon dioxide-equivalent emissions from the air. Hertz says it will invest in becoming the largest renter of EVs in North America and notes that it already has tens of thousands available at 500 locations in 38 states. By the end of 2024, it plans to electrify a quarter of its fleet. Electric rental cars are a great way for travelers wanting to avoid gas, and they make excellent urban commuter cars. Hertz will also likely save a few dollars by avoiding oil changes and other routine maintenance that gas engines need. However, a hidden societal benefit of this deal may come when Hertz’s EV rental customers begin shopping for new cars. Many people are skeptical of EVs for various reasons, including range, charging, ease of operation, and cost. Giving people a low-risk introduction to EVs and the ability to test-drive one without a pressuring salesperson could drive more people to electrics. At the same time, there's also the risk that renters wanting to take their Hertz-GM EV on a road trip into sparsely populated areas may return with charging and range-related horror stories. Hertz currently doesnÂ’t ask what youÂ’re planning to do with your rental, but it does offer a chat service for questions, and range information is presented clearly on each vehicle.

GMC Sierra 1500 AT4X: Can you sleep in it?

Autoblog may receive a share from purchases made via links on this page. Pricing and availability are subject to change. The recently introduced GMC Sierra AT4X is an impressive combination of off-roading and luxury. But can you sleep in it? Pickups are great for towing campers or as a platform upon which to build out overlanding rigs, but from the factory they usually aren’t as useful as SUVs to sleep in, considering half of the length of the vehicle is taken up by the bed. Let's see how the AT4X fares. Space The biggest thing to consider when it comes to camping in your car is whether or not there is enough space in it for you and possibly a partner to lay down comfortably. This is tough when it comes to pickup trucks, which are hampered by the fact that half (or more) of the length of the vehicle is taken up by the bed of the truck. Some trucks have added features like lie-flat seats that make sleeping in them a bit easier, though itÂ’s still not a perfect solution. Unfortunately the AT4X is not one of those trucks. While the seats do lay back quite a good amount, I wasnÂ’t able to get comfortable enough to rely on them for a good nightÂ’s rest. To the rear we go. If youÂ’re vertically challenged, you may be in luck, especially if you donÂ’t sleep stretched out. The Sierra 1500 is a wide truck, almost 7 feet wide in fact. The rear bench measures 56 inches in width, which isnÂ’t a great option for most adults unless you really like sleeping in the fetal position. ItÂ’ll do in a pinch but I wouldnÂ’t expect to get a great night's sleep again and again.  Below the bench, which folds up and out of the way, is a relatively flat floor which can offer a bit more length. At 63” it still isnÂ’t enough for me to lie down with the doors closed, but it is much less cramped than spending the night on the bench. The subtle bump in the middle of the floor, which is much less severe than the ridges in the bed, can easily be remedied by an inflatable sleeping pad like the Sea to Summit Ether Light XT, or, even better, a cheap air mattress from Walmart. The Bed The bed of the AT4X seems like the most logical place to sleep. After all, it is named the bed for a reason right? If you have an inflatable mattress, then sure, but due to the ridges on the floor, a simple sleeping pad and sleeping bag will not be enough here. Additionally, the length of the bed leaves something to be desired.
