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 Corvette Z06 C7.R Edition brings track style to the road

The Chevrolet Corvette has a long history of excelling at endurance racing, and continues to dominate today. To celebrate that legacy, Chevy is bringing some of the look of its track machine to the road with the 2016 Corvette Z06 C7.R Edition. These machines might be gone faster than the racecar's lap time around Le Mans, because the company is building just 500 of them. All of these track-inspired, special editions are based on the 650-horsepower, supercharged Z06 in the top 3LZ trim, and they also come equipped with the Z07 Performance Package that includes carbon-ceramic brakes, adjustable aero elements, and Michelin Pilot Sport Cup 2 tires. Offered as a coupe or convertible, these 'Vettes use some tricks to match the style of the C7.R. They're available in the racer's traditional bright yellow livery, but black is optional. Unpainted carbon fiber trim (including material for the hood) and grilles that are painted Spectra Gray Metallic also add to the motorsport look. The car rides on a set of black wheels with Corvette Racing logos on the center caps. Inside, buyers of this limited edition are nestled in Competition Sport Seats that are upholstered in Jet Black leather. Suede microfiber accents with yellow stitching cover the steering wheel, gearshift, instrument panel and doors. Plus, there's some additional carbon fiber trim for good measure. Each car also comes with a cover with C7.R graphics. Chevy isn't disclosing the price for the Z06 C7.R Edition yet, but the limited edition model is slated to hit the market later this year.

It's offered in Corvette Racing's signature yellow livery – or black – with coordinated exterior and interior accents. Only 500 examples of the C7.R Edition will be built and all will include the Z07 Performance Package with carbon ceramic brakes, as well as a specially serialized vehicle identification number. They go on sale later this year. "Corvette Racing's legacy and technology were significant influences on the development of the Corvette Z06 and the new C7.R Edition honors the direct link between the racecar and the production model," said Harlan Charles, Corvette product and marketing manager.

Chevy Volt 'acceptable,' Nissan Leaf 'poor' in new IIHS safety tests

Ford C-Max Hybrid also scored "acceptable" rating. With US Nissan Leaf sales up almost 30 percent during the first half of the year, the only thing that might be able to stop the battery-electric vehicle is a good, stiff barrier. Unfortunately, thing's aren't always pretty when that happens in the real world, according to new tests from the Insurance Institute for Highway Safety (IIHS). Things with the Chevrolet Volt extended-range plug-in are a little bit rosier, though. The two plug-in vehicles were part of a batch of a dozen vehicles that just went through the IIHS's "small overlap" test, in which the driver's side front corner of the vehicle is crashed into a rigid barrier at 40 miles per hour. Out of the dozen, only the Mini Cooper Countryman was given a "good" rating. Five vehicles, including the Volt and the Ford C-Max Hybrid, were rated "acceptable," two were "marginal" and two, including the Leaf, were "poor." Plug-in vehicles are unique in the crash-test context because of their relatively large battery sizes. In the Volt's case, the driver had a "low risk" of injury, said the IIHS. But the Leaf's crash substantially pushed back the instrument panel and steering column, creating a scenario where the driver was "likely" to sustain leg injuries. The batteries in both the Leaf and the Volt passed safety tests specifically targeted at things like thermo and electrical properties and overall integrity. "Nissan is proud of the Leaf's 'Good' rating in all other IIHS tests, a 4-star NCAP rating from NHTSA and its IIHS Top Safety Pick rating in all previous years since the car's release," the company said in an e-mail sent to AutoblogGreen. "As for the performance of the 2014 Leaf in the 'small overlap frontal test,' Nissan will continue to review these and other results from the IIHS 'small overlap frontal test' as we seek opportunities for improvement." Check out the IIHS's press release and small car crash-test video footage below. Range of ratings: Small car ratings run the gamut in challenging small overlap front test The Mini Cooper Countryman is the only small car to earn a good rating among the latest group of 12 cars subjected to the Institute's small overlap front crash test. Two electric models and a hybrid also are in the mix, with varied results. The electric-powered Chevrolet Volt (with a gasoline engine "range extender") earns an acceptable rating, while its battery-electric rival, the Nissan Leaf, earns a poor rating.
