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.

Chevy trademark for E-Ray may signal Corvette hybrid or EV

A spy photographer and friend of Autoblog Chris Doane spotted this trademark filing with the US Patent and Trademark Office, and there's not much to it: Chevy is calling dibs on the "Corvette E-Ray" name, and that raises more questions than answers. Being obsessed with this industry is an Autoblog core value, and Corvette is perennially a big deal. It's also historically, and famously, resistant to change. So what's going on here? Unless it's a pure show car, it's unlikely the E-Ray will be a C7-based hybrid. The current Corvette is a tightly-packaged thing, and batteries are bulky. That makes a concept of some sort all the more likely, especially with the Detroit Auto Show coming up. Unconstrained by the packaging of the real-world Stingray, this E-Ray concept may be a pure EV, or a hybrid, of any configuration. GM has built mid-engined Corvette concept cars in the past, and maybe we'll see one again in a few weeks. A gutted C7 with a pure EV drivetrain is also a remote possibility, although less likely – the Stingray wasn't engineered with that in mind, and we think GM's too big to show off a hack-job at a major auto show. Not that it is a Corvette competitor, but don't forget that the Tesla Model S P85D and it's P90D successor have taken pure EV performance into the mainstream – the upper end of the mainstream, to be sure. It has been enough to draw industry performance players into the genre. Look at Aston Martin's production-possible RapidE concept, a pure EV, and the confirmed-for-production Porsche Mission E. We've heard rumblings in the past that Corvette may become a marque unto itself, spawning a variety of variants (including the hypothesized mid-engined production car – don't hold your breath). Perhaps the gas-powered C8, in whatever form it takes, will be complemented with a greener version. We'll try to dig up insider information about what the E-Ray will reveal itself to be, but rest assured that if it shows up at Detroit we'll bring you analysis of every inch of it.Related Video: Featured Gallery 2016 Chevy Corvette Z06 C7.R Edition View 9 Photos Tip: Chris Doane/Facebook Green Rumormill Detroit Auto Show Chevrolet Electric Future Vehicles Hybrid Performance corvette stingray

Jaguar I-Pace vs. Tesla Model 3 and other EVs: How they compare on paper

The 200-mile club of electric vehicles is really growing. The most recent member is the Jaguar I-Pace, the company's first pure EV. It promises luxury, performance, style, and most important, good range. Nearly as recent is the Hyundai Kona EV, and while it doesn't promise luxury or performance like the Jaguar (it's also smaller), it does pack impressive range. With the introduction of both of these electric cars, we thought we would see how they compare against each other, and the other two big names in high-capacity electric cars: the Chevy Bolt EV and the Tesla Model 3. This isn't intended to be a direct, apples-to-apples comparison, as the four are quite different. If anything, they break into two groups: bigger and more luxurious, and smaller and less expensive. Then again, the number of vehicles with this electric range is small and comparisons to EV's with less range wouldn't be too kind to the other guys. If you want to learn more about these EVs, and compare them with other cars, be sure to check out our Car Finder and comparison tools. Horsepower and torque There is one clear winner here, and that's the Jaguar I-Pace. It packs a whopping 394 horsepower and 512 pound-feet of torque. That comes through a pair of electric motors (one at the front, another at the rear) that provide the Jag with all-wheel drive, the only one of these vehicles to offer it (at the moment). Altogether, it allows the I-Pace to have the best 0-60 mph time of 4.5 seconds. At the other end of the spectrum is the Hyundai Kona EV. It's front-drive, like the Bolt EV, and has effectively the same amount of horsepower as the Chevy at 201 horsepower, but its 0-60-mph time is almost a second slower. And the low-range version of the Kona, excluded because it doesn't go more than 200 miles between charges, is slower still. The Tesla Model 3 is the only vehicle with rear-wheel drive, and with a 0-60 mph of 5.1 seconds for the Long Range model, it is still very quick. Range and energy use Frequently, the all-consuming question with electric cars is, "How far can I go on a charge?" And to go the farthest, you need the long-range Tesla Model 3. It can go 310 miles. It has the added advantage of being able to use the network of Tesla Supercharger stations, though they are pay-per-use with the Model 3. Even the lower capacity Model 3, with just 220 miles of range, can use these stations.
