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.

Recharge Wrap-up: Chevy Volt's new, improved powertrain; Inabikari wants to build Tesla Model X fighter

We knew the 2016 Chevrolet Volt's new powertrain would provide more range, but we didn't know how much. According to GM's Executive Director Larry Nitz, it is about 12 percent more, overall. "I can't think of a powertrain we've re-engineered more extensively within a five-year period than this one," he said. The battery, electric drive system and gasoline generator have all been reworked to allow for an overall driving range of up to 425 miles, with electric range speculated to reach 42 miles or more. The new Volt will also benefit from 20 percent quicker low-end acceleration, weight reductions and improvements in NVH. Read more at Hybrid Cars and at the SAE website. Hyundai's FCEV research and development boss, Dr. Sae-Hoon Kim, is optimistic about the future of hydrogen mobility in Japan. With the Tucson Fuel Cell already in production ahead of Toyota's FCV, Hyundai has a foothold in the hydrogen car scene. Kim believes that since the Fukushima disaster, Japan's attitudes toward energy make it friendly to a growing hydrogen economy. He also says that hydrogen won't be limited to Hyundai, with Kia getting all the battery EVs. "Both types are for both companies," Kim says. "For the moment, volumes are small and it is not wise to have Hyundai and Kia competing." Read more at Just Auto. The Latvian/German startup Inabikari is using crowdfunding to build an electric crossover for Europe. The Rev.01 EV hopes to compete with Tesla's upcoming Model X with a range of over 400 miles and a five-second 0-60 time. The group currently is trying to raise initial funds through an Indiegogo campaign, with hopes of more investment in the future and sales beginning in 2017. See the video below, and read more at Hybrid Cars and at the Inabikari website. Fuel economy and emissions regulations could lead to some interesting design changes to automobiles. The World Light Duty Test Procedure, set to replace the New European Driving Cycle in 2017, will push automakers to find new ways to reduce drag on their vehicles. For better aerodynamics, we could see traditional side-view mirrors replaced by cameras that display what they see on screens inside the vehicle. Another likely change will be the introduction of smaller, narrower wheels. Improving the average drag coefficient from 0.32 to 0.20 could reduce CO2 emissions by as much as 20 percent.

Can Fernando Alonso win Indy? Here's why and why maybe not

SPEEDWAY, IN – The month of May has been a joy ride for Fernando Alonso at Indianapolis Motor Speedway. The two-time Formula 1 champion came to Indy having never turned left in a race car without also turning right. But he acquired such a feel for Indy's 2 1/2 -mile rectangle during a month of practice and qualifying that he's considered a strong contender to win the 101st Indianapolis 500 on Sunday, rookie or not. "You're not trying to bring somebody on who has very little experience driving very high-performance cars," said 2003 Indy 500 winner Gil deFerran, who this month has helped Alonso learn the nuances that make the speedway such a tough place to conquer. "I suppose it would be a little bit different if you were dealing with a younger, much less experienced person." Driving a McLaren Honda from the potent Andretti Autosport team, Alonso was consistently near the top of the speed charts in practice, he qualified fifth fastest at 231.300 mph, and he handled runs in heavy traffic like a driver who'd done it many times before. But those were the prelims. The race is another creature. "The car felt the best (it has) in the last two weeks. I was making some moves, taking some different lines. I am extremely happy." Other drivers say the speedway looks different on race day when the crowd, expected to top 300,000, fills the grandstands and makes an already narrow track seem even tighter. The three-wide rolling start is something Alonso has never experienced, and he will see the green flag from the middle of the second row between Takuma Sato and J.R. Hildebrand. And the space he'll be given by his competitors in the first 180 laps may disappear In the last 20 when it's every driver for themselves. Can a rookie like Alonso win this race? Absolutely, as Andretti driver Alexander Rossi showed last year when his team used a fuel-mileage strategy to win in his first taste of Indy. We're talking about Fernando Alonso here, who easily could show his rookie stripes to the rest of the field most of the day. His best lap in Friday's final practice, 226.608, was fifth fastest in the field and, more important, he said the car felt comfortable in heavy traffic. "The car felt the best (it has) in the last two weeks," Alonso said. "I was making some moves, taking some different lines.
