Chevy SS prototype spotted wearing Pontiac G8 clothes

Do not adjust your computer screen, you are not seeing the rebirth of the Pontiac brand. General Motors has chosen to use a G8 to disguise a test mule for the latest prototype of the forthcoming Chevrolet SS. The G8 was closely related to the Holden Commodore and Vauxhall VXR, the platform upon which the new Chevrolet performance model will be based. It should come as little surprise, then, that GM has opted to use the cladding from the former G8.
Thought the front clip of this mule is pure Pontiac, note the vents immediately behind the front wheel. That is a distinctive design hallmark of the Vauxhall VXR. Also note that this vehicle is right-hand drive, as the Holden and its Chevy counterpart will be very closely related. That likely includes potential drivetrains. The spy photos of this mule also reveal very wide rear tires, and rear wheels that do not match the fronts.

GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

GM cutting vehicle trim options to save money for electrification

Information continues to filter out about GM's plans based on comments the automaker made during its Capital Markets Day event in February. GM President Mark Reuss said the company's push to save money by rationalizing the number of build combinations will continue in 2020, carrying on the work done in 2019. As GM Authority covers, last year, the carmaker cut 3,500 components across model lines, a 12% drop in the number of parts it needed to stock in its plants. Reuss used the next-generation Chevolet Equinox and GMC Terrain as examples for more cost efficiencies, saying build possibilities — which include international markets and their options — will be cut by more than 50%, and use more shared parts. "We will reduce total trim levels on Equinox and Terrain from eight to six," Reuss said, "reduce engine variants from 11 to 5, reduce build combinations from more than 200 to less than 100 per program, and see significant cost savings of an already paid-for architecture that took the mass out, helping us self-fund electrification programs." GM will plow a large amount of the money it saves into its ambitious EV program. In 2017, the automaker said it intends to have 20 electric vehicles on the market by the end of 2023, some of which could be shared between brands. An automotive analyst at Seeking Alpha and a piece in Automobile attempted to put specifics to what we should expect. As Automobile points out, the first two EVs in the 20-car program are already on sale, being the Ariv Meld and Ariv Merge eBikes available in Belgium and The Netherlands. We've seen the Cruise Origin autonomous rideshare taxi, although we don't know when it will hit the road. The next three, which we should see in the metal shortly, are two Cadillac EVs and the GMC Hummer EV pickup. The Cadillac pair are expected to be sized like the XT4 and XT5, and along with the Hummer, should hit the market starting in late 2021.
