GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

Chevy to show redesigned Captiva in Geneva, will it come to US rental lots?

Unless you're renting a car or driving through Orlando, Florida (the rental car capital of the US), you'll probably never see a Chevrolet Captiva - the rebadged, fleet-only version of the old Saturn Vue - on our roads, but this crossover is popular in many other parts of the world. As such, Chevrolet announced that the Captiva will be getting an update for 2013, which will be unveiled next week at the Geneva Motor Show.
Coming off a pretty extensive refresh in 2011, the 2013 model year will bring even more changes to the Captiva like LED taillights, new 18-inch wheels and revised fascias with a new grille and fog lights up front and inset chrome exhaust outlets at the rear. New interior features include heated rear seats, dual-zone climate control as well as available options on some of the upper trim levels such as leather seating and keyless entry and start. We have yet to hear back from Chevrolet as to whether or not the updated Captiva will be making its way to a rental lot near you, as the model is only available in the US to fleet buyers.
Alongside the updated Captiva, Chevy is also showing off its new Trax in Europe, where the subcompact crossover will go on sale this spring. GM's press release for these two Geneva-bound models is posted below.

Opel's own ad shows Ampera-e beating Opels in drag race

The Opel Ampera-e isn't expected to set any world records on a quarter-mile drag strip. But when it comes to crossing a major boulevard, though, the European version of the Chevrolet Bolt electric vehicle will more than hold its own, potentially scaring inattentive pedestrians everywhere. According to a 35-second video posted by General Motors' Opel division, at least. Opel set up the Ampera-e against four other small-and-sporty vehicles, including racing versions of the Opel Adam and Opel Astra as well as stock versions of the Opel Insignia and Corsa (what, you expected a Corvette to be in there?). With the EV's off-the-line torque as a selling point, Opel showed the Ampera-e beating the other vehicles in a 30-meter (100-foot) drag race. Of course, the video also shows the EV getting passed by some of the others soon after, but the point was made. Opel doubled down by adding the tagline "Fun to Drive" at the end of the video. While Opel hasn't revealed the single-charge range of the Ampera-e, it should be roughly the same as the Chevrolet Bolt, which will be about 200 miles. In addition, the Ampera-e, like the Bolt in the US, will get 200 horsepower from its electric motor, and will be able to go from 0 to 60 miles per hour in less than seven seconds. The Ampera-e will debut at the 2016 Paris Motor Show later this month. General Motors said in February that Europe would get the Ampera-e by next year. Opel had previously used the Ampera name with the Euro version of the Chevrolet Volt extended-range plug-in.
