Next-generation Chevrolet Colorado breaks cover in new spy photos

The next-generation Chevrolet Colorado broke cover in this fresh set of spy photos this week, giving us a glimpse of what to expect when GM's compact trucks are replaced in what is expected to be either 2023 or 2024.  Thanks to its still-extensive camouflage, this prototype doesn't give away a ton about the new Colorado's styling, but in profile, it appears as though the swoopy, upswept rear cab line might become a thing of the past. We wouldn't be surprised to see the new Colorado adopt a more angular, squared-off look more akin to that of its big brother, the half-ton Silverado. The Silverado is also expected to donate what may be the new Colorado's only powertrain. Taking a cue from Ford, Chevy is expected to offer the next-gen Colorado with just a turbocharged four-cylinder engine — the new corporate 2.7T in this instance. The large, 310-horsepower four-pot can easily take over for the 3.6L V6 currently available in the GM twins and one-up the 270-hp Ranger to boot. This would mark the end of both a V6 and diesel option being offered in GM's midsize trucks, and tracks with the company's slow, silent effort to eliminate lower-margin models. We say "trucks" because, well, whatever happens with Chevy is likely to translate to GMC. The Canyon will be due for replacement at the same time, and will likely carry on as a re-skin of Chevy's offering. We're not yet certain exactly when Chevrolet will start selling the next-gen Colorado, but given the reasonably complete state of this prototype, we expect it won't be long now. Rumors suggest it could hit the market in 2023 as a 2024 model.  Related Video: The Best Midsize Pickup: Ranger vs Gladiator vs Tacoma vs Colorado

Why an independent rear suspension for GM's new, full-sized SUVs wasn't easy

A Motor Trend report last month laid out how Cadillac's 4.2-lier twin-turbo Blackwing V8 could be an orphan due to cost concerns in the GM empire. Last-minute chassis changes to Cadillac's new sedans and XT6 crossover led to engine bays that couldn't fit the Blackwing. On the SUV side, according to the report, the new independent rear suspension for big people haulers cost so much to implement that GM ruled out reworking the Escalade to accept the Blackwing. At least one commenter rightly asked how could a suspension swallow that much money. A new piece in Motor Trend has the answer. The excellent Alissa Priddle spoke to Tim Herrick, GM's executive chief engineer for full-size trucks, about why the clean-sheet IRS cost "multimillions of dollars."  First, GM would need to build a new body shop at the Arlington, Texas plant that assembles the automaker's big SUVs to stamp the numerous wholly new parts and panels accommodating an IRS. Then GM would need to design and pay for a new assembly process. On top of those up-front costs, there was the incremental cost of the four-link IRS components being more expensive than those in the trucks' former leaf-sprung solid axles. Herrick endured so many rejections for so long that he remembers the date and time when he got approval for the new unit. He said it came down to a meeting where he told a higher-up, "I'll make you a deal: If we get to the reveal, or if we launch this and you think this was a dumb idea, I'll hand you my badge and let you walk me out." Head to Motor Trend to read the full story. Based on Herrick being on stage to help present the new SUVs to the press, and on our First Ride in the new Chevrolet Tahoe and Suburban at GM's Milford Proving Grounds, it appears this will have a happy ending for all involved. Furthermore, since Herrick worked on the T1 platform that supports the big SUVs as well as the light- and heavy-duty pickups, he understood the demands on the commercial side, too. That could be why when Roadshow asked Tim Asoklis, chief engineer of the Tahoe and Suburban, if the new IRS could endure life in the Chevrolet Silverado and GMC Sierra, Asoklis answered, "Oh, absolutely."

Recharge Wrap-up: Chevy hits CO2 goal, eVgo and BMW build fast charging

Chevrolet has met its goal of preventing 8 million metric tons of CO2 emissions over the last five years. Through its community-based carbon reduction initiative, Chevy invested $40 million and took part in 38 different projects in 29 different states. The projects included supporting wind farms, powering a hospital with landfill gas, helping truckers reduce their idle time and helping create the ongoing #CleanEnergyU dialogue between students and clean energy leaders. In the end, Chevy retired all its carbon credits rather then spending them to offset its own emissions. Read more from Chevrolet. NRG eVgo and BMW are partnering to add DC Fast Combo charging to locations around the country. Over the next two years, the groups will bring hundreds of the 50-kW chargers to 25 cities, with 24 of those markets getting at least one installed by the end of 2015. "eVgo will add reliable DC Fast Combo capability to what is already America's largest DC Fast charging network," says eVgo President and CEO Arun Banskota. "This will be the fastest and most cost effective build out of a new network ever – thanks in large part to our existing infrastructure and committed retail host partners." Read more in the press release from eVgo. The EPA has settled with a Utah gasoline refiner over Clean Air Act violations. The HollyFrontier Corporation subsidiaries will pay $1.2 million for producing about 42 million gallons of gas that didn't adhere to Reid Vapor Pressure standards, resulting in 10 excess tons of volatile organic compound emissions. Its Salt Lake City refinery will also implement a program to offset past emissions. "This agreement will benefit public health by requiring retrofits of storage tanks at HollyFrontier facilities that will reduce volatile organic compound emissions and use next generation technology to verify these reductions," says Assistant Attorney General John Cruden. "This settlement shows that fuel refiners can and must meet the nation's standards for controlling the emissions that cause ground level ozone and serious health problems for Americans."
