GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.

2016 Chevy Volt sneak peek at CES

Here it is, folks – your first real glimpse at the 2016 Chevrolet Volt. The gasoline-electric sedan will officially debut at the Detroit Auto Show next week, but Chevy gave us a sneak peek of its redesigned Volt at a media event in Las Vegas late Sunday, as part of its CES festivities. There isn't a ton to see here, and sorry about the low quality video (and for us not standing front and center during the reveal). But we can clearly see the car's redesigned front fascia – something recently previewed at a fan event in Los Angeles. For another view, check out a high-res photo of the new Volt from our friends at The Verge, here. Chevy even tweeted a photo of the Volt's new nose on its official Volt Twitter account, which you can see below. The automaker didn't divulge any details about its new Volt, but we already know quite a bit. For starters, the Volt will use a new, 1.5-liter gasoline engine and won't require premium fuel. It'll have more EV range and a bigger battery, too. We'll have a whole mess of information when the 2016 Volt is fully revealed in Detroit in about one week's time. In the meantime, here are some more looks at the Volt, courtesy of the Twitterverse. We're so excited about #NextGenVolt we brought it out early at #CES2015!

Weekly Recap: Ford guns for 2016 Le Mans glory with new GT

On the eve of the 24 Hours of Le Mans, Ford confirmed it will return to the French endurance race in 2016 and campaign the new GT racecar 50 years after three GT40s swept the podium at the Circuit de la Sarthe. The factory will back a two-team, four-car effort that will compete in the World Endurance Championship and the Tudor United SportsCar Championship running cars operated by Chip Ganassi Racing with Felix Sabates. The GT racecar will make its track debut in January at the Rolex 24 at Daytona, and the driver lineup will be announced later. "But rest assured, there's quite a line forming out the door," Ganassi said at the announcement. The GT is the modern successor to the iconic GT40, which won Le Mans four straight years from 1966-1969. The racecar is a rolling testbed of Ford's latest technologies, including a powerful twin-turbo EcoBoost V6. The car also makes extensive use of carbon-fiber pieces and advanced aerodynamics. Ford tapped Multimatic Motorsports of Canada and Roush Yates Engines to aid in the development of the GT racer. The road-going version, which was revealed in January at the Detroit Auto Show, is also set to launch next year. It caps Ford's growing performance lineup, and the company has ambitious plans to launch more than 12 new sporty models by 2020, including hot metal like the Focus RS, F-150 Raptor, and Shelby GT350R. The GT embodies Ford's best tech, but news of its return to Le Mans immediately conjured images of the company's fierce rivalry in the 1960s with Ferrari and intense competition with Porsche. "When the GT40 competed at Le Mans in the 1960s, Henry Ford II sought to prove Ford could beat endurance racing's most legendary manufacturers," Ford executive chairman Bill Ford said in a statement. "We are still extremely proud of having won this iconic race four times in a row, and that same spirit that drove the innovation behind the first Ford GT still drives us today." Ford is going back to Le Mans. Somewhere, Hank the Deuce must be smiling.
