GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.

The Chevrolet Bolt is headed to China as a Buick SUV

When spy photos of what appeared to be Chevrolet Bolt EV with some minor front- and rear-end updates circulated last week, Autoblog surmised that GM was working on some sort of Bolt-based vehicle — potentially a crossover — to be sold in China as a Buick. We may just have corroboration for that theory. On Thursday, Motor1.com spotted a story published earlier this week on the Chinese site Auto Home which claims that GM has applied to sell an all-electric SUV under the Velite 7 nameplate in China.  There's little differentiating the Velite 7's exterior from the Bolt EV's, apart from bumpers, badges, and a little extra ground clearance. Up front, the bowtie is replaced by a round Buick badge, and the bumper picks up an almost Prius-like appearance thanks to contrasting vertical elements and a thin grille bleeding into the head lights to give it a full-width appearance. Chevy Bolt-based prototype View 16 Photos If the Chinese report is accurate, there is one significant difference under the skin. Per the application, the Buick crossover variant is to be powered by a 174-horsepower electric powertrain. That's down 26 horsepower from the Bolt EV's powertrain, and we can't help but think that a lifted Buick variant might just need every pony it can get.  The needs of the Chinese market are unique, and we're certain GM knows what it's doing if these figures are accurate. We have no reason to believe Buick plans to sell the Velite 7 EV here in the States, though we expect an updated Chevy Bolt eventually, and we wouldn't be surprised if Buick brings something along shortly to fill the void left by the departure of the Regal sedan and its variants.  Related Video:

2015 Chevrolet SS Review [w/video]

The Chevrolet SS is one of the best cars no one's buying. It's a Bowtie-badged version of the Australian Holden Commodore with a 6.2-liter LS3 V8 under the hood. It's got a six-speed manual transmission, General Motors' sophisticated Magnetic Ride Control suspension, and rear-wheel drive. It's a fullsize sedan that comes with every possible amenity you could want. And it's less than $50,000. Chevrolet sold 2,479 SS sedans in 2014. That means it was outsold by every other vehicle the automaker offers, even the police fleet-only Caprice. (I'm only talking about cars that were on sale for the full 2014 calendar year, of course.) The aforementioned manual transmission and MRC suspension were added for 2015, but it's not clear if that's helping. The SS is down 7.7 percent through June of this year, compared to 2014's numbers. But hey, at least it's finally outselling the Caprice. What a damn shame. Granted, GM only planned to sell a few thousand of these each year, but as enthusiasts, this a car we should be gobbling up. It's the closest we'll get to a four-door Corvette, and with the 2015 model year updates, that statement is more true than ever. People often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Aside from the manual gearbox and magnetorheological suspension, the SS is largely unchanged through its year and a half of sales. But that's no bad thing – we were thoroughly impressed with the SS when we first tested it at the end of 2013. Outside, the SS looks the same, which is a bummer. It is not an attractive car, and the chrome brightwork on the side vents and wheels doesn't help. That said, the sedate styling puts it under the radar – more so than competitors like a Dodge Charger 392, anyway. But maybe it's too under the radar. Even in the new, "Some Like It Hot Red" color (yes, really), photographer Drew Phillips reports that people often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Exterior styling is our only gripe with the SS. Moving inside, there's a lot to like. This is easily one of Chevy's nicest, well thought-out interiors (thanks, Holden), with premium materials and tons of equipment. The Chevy MyLink infotainment system carries over, and now features 4G LTE and wifi connectivity. The touchscreen is a bit slow to respond, but otherwise, it's bright, well organized, and packed with functionality. This is easily one of Chevy's nicest, well thought-out interiors.
