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.

2023 Detroit Auto Show Editors' Rankings

The 2023 Detroit Auto Show was back in its traditional location, though in its fall spot in the calendar, and it was another pretty quiet event. By our count, only five new models, or model lines, were revealed and brought to the floor; all of which came from Detroit's own car companies. Still, some of them were quite significant, and the types were diverse. Naturally, we also had our favorites. So take a look to see how we ranked the reveals of the Detroit Auto Show. 2025 Cadillac CT5 View 15 Photos 5. 2025 Cadillac CT5 The refresh for the 2025 Cadillac CT5 is no great revelation, because it doesn’t have to be. An already solid, attractive design means only light tweaks were made to its appearance, and the new front fascia and redesigned lights just make the CT5 just that much more aggressive. So what was missing from the current model? Apparently, the answer was a gorgeous 33-inch curved LED display serving as both infotainment and instrument cluster. It has touchscreen capability to both the right and left sides of the steering wheel, and provides 9K resolution. Update some of the safety and driver assist tech, and — boom — the CT5 is properly modernized. Now bring on the updated Blackwing. –Senior Editor, Green, John Snyder 2024 Jeep Gladiator Live View 10 Photos 4. 2024 Jeep Gladiator Jeep carved out plenty of time for what is essentially a no-brainer mid-cycle refresh, but thereÂ’s one among us who is easily swayed: Me. I dumped the maximum number of points allotted on the 2024 Gladiator with only three words of explanation: "I like Jeeps." But this is kind of a big deal. The Gladiator pulled a lot of weight for Stellantis during the pandemic by providing an alternative to pickup buyers while Ram dealers were scraping the bottom of the supply barrel. To be fair, we're probably giving the Gladiator a bit of advance credit here for its promise to deliver a 4xe variant in 2025, but who else is talking about their PHEV pickup plans? Your move, Ford. –Associate Editor Byron Hurd. 2024 GMC Acadia AT4 View 17 Photos 3. 2024 GMC Acadia The 2024 GMC Acadia is the one reveal from this yearÂ’s Detroit Auto Show that was actually a totally new vehicle, and as far as three-row SUVs go, GMC aced it. The exterior has its own personality separate from its Chevrolet Traverse twin. Its AT4 trim is legit with more ground clearance, a torque-vectoring rear diff and sweet orange marker lights on the fenders.

Junkyard Gem: 1973 GMC Sierra Grande Camper Special

Starting in the 1973 model year, General Motors introduced the "Rounded Line" family of C/K-series Chevrolet and GMC trucks, and sales of the pickup versions continued all the way through 1987. Nice examples of these trucks can sell for large money, but the junkyard teaches us that not all collectible vehicles are worth rescuing and fixing up. Here's a reinforcement of that lesson, courtesy of a first-year GMC C2500 Camper Special with the high-zoot Sierra Grande trim level, found in a self-service yard just outside of Denver, Colorado. I'm no GM truck expert, but I know enough to stay clear of the battles over what to call this pickup. Let's just say it's a three-quarter-ton, rear-wheel-drive third-gen C-Series with really cool badges. Yes, I bought this badge for my garage wall, and it was totally worth the $4.23. GM came up with the Camper Special package during the late 1960s, when removable pickup campers became popular, and for 1973 it included heavy-duty springs and a wiring harness made to plug into the connectors on slide-in truck campers. It also included woodsy-looking badges, but someone pried the ones off this truck before I could buy them. This may well have been a one-owner truck, because it still had original warranty paperwork inside. Here we see that it was purchased new on August 2, 1973 (which happens to be the day that George Brett got his very first hit in the big leagues) by a resident of Compton, California. Yes, that Compton. The build tag tells us that this Camper Special was born at the Fremont Assembly plant in California, which became the GM-Toyota NUMMI venture in 1984 and is now the Tesla Factory. I think most 1973 C/K pickups sold new in Colorado would have come from Pontiac Assembly in Michigan. There was a time, not many years ago, when a genuine 454-cubic-inch (that's 7.4 liters to those of you sweating under the oppressive weight of the French Empire's Measurement System) big-block Chevrolet engine would have been yanked out and purchased within hours of hitting the rows of a yard like this. These days, engine-swappers can get more power with less weight from any number of donor vehicles. If this engine is the original 454, it was rated at 240 horsepower and 355 pound-feet (down from 270 hp in 1972 due to emissions-related changes). This truck had a three-speed automatic transmission, like most optioned-up Detroit pickups of its era.
