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.

EarthCruiser adds a bigger camper option to its heavy duty pickup line

EarthCruiser is a camper and expedition vehicle company based out of Oregon that we've previously covered for its huge commercial truck-based machines. But they offer more than that, from drop-in campers for smaller pickups to heavy duty pickup conversions. The company's latest product is one of the latter, offering a larger camping area than the current EXD model. This new camper conversion is called the Terranova. The big differentiator between it and the EXD is the camper section, which extends over the truck cab on the Terranova. This means that bed space can be moved to above the truck cab, instead of having to use a convertible dinette. So less reconfiguring, and generally more usable space. One other major difference is that the EXD is only available for the Ram 3500 and Ford F-350. The Terranova is being designed for both of those trucks as well as the Chevy Silverado 3500. The EarthCruiser Terranova is otherwise very similar to other EarthCruiser models. The camper section is made of fiberglass and plastic, and the pop-up roof is insulated with foam. The curtains are triple-layered. The company says it can house four people. It comes with a freshwater tank and pump to help supply the kitchen sink, drinking water tap, bathroom sink and indoor and outdoor showers. There's also a cassette toilet. The kitchen features an induction stove top and small refrigerator and freezer. A fan system is standard, and air conditioning is optional. Power comes from a 400-aH lithium-ion battery. The Terranova isn't yet available. EarthCruiser is finishing up design and engineering, and it plans to have finished examples early next year. The company is taking reservations now, though. Pricing hasn't been announced, but an EXD runs between $220,000 and $265,000, and we would expect the Terranova to cost even more.

Nissan Leaf has 2nd-best sales month ever, Chevy Volt does a 2013 repeat [UPDATE]

UPDATE: The official press release says that "Volt [sales were] up 7 percent," but Randy Fox let AutoblogGreen know that this is simply due to a change in the fleet/retail mix between March 2013 and 2014. The actual number sold was exactly the same in the two months. A month ago, Nissan's director of EV sales and marketing, Toby Perry, said he expected to see the Leaf's sales momentum continue into March. It wasn't a big leap, since January and February were slow sales months in 2013 (around 640 each) before a big climb to 2,200 in March. In 2014, the first two months of the year were better (around 1,300 each) but Nissan can still be happy that the Leaf just had the best March ever and its second-highest sales month ever, with 2,507 sold. That's a 12.1 percent increase from 2013 and Perry said in a statement to AutoblogGreen that one reason is all of the buyers who are becoming evangelists for the vehicle. "We've also seen an increase in showroom traffic as we enhanced our marketing presence in March," he said. Nissan pointed to cities like Washington, DC, Raleigh-Durham, NC and urban areas in Texas as strong Leaf markets last month. On the Chevy Volt front, January and February were also slow months in 2014, down roughly half from the 2,000-ish the plug-in hybrid was selling at the end of 2013. For 2014, sales were up slightly from the first two months of the year and Chevy spokesman Randy Fox told AutoblogGreen that the March number was "pretty flat, year-over-year." Even with that warning, we were surprised to see the total come in at 1,478. Why's that? Because the total for March 2013 was ... 1,478. So, yeah, that's pretty steady even if there were 26 selling days in March period this year compared to 27 last year. As always, our more complete report of last month's green car sales will be coming soon. News Source: General Motors, Nissan Green Chevrolet GM Nissan Electric Hybrid PHEV ev sales
