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.

Junkyard Gem: 2005 Chevrolet Aveo LS Sedan

The story of Daewoo in North America took some interesting plot turns over the decades. First we had the 1988-1993 Pontiac LeMans, a rebadged Daewoo LeMans. A bit later, Daewoo began selling cars under its own nameplate here, with the Lanos, Nubira, and Leganza available for the 1999-2002 model years. Then Daewoo fled the continent and left warranty service of those cars in the hands of Manny, Moe, and Jack. With GM taking over Daewoo Motors after Daewoo's bankruptcy, we got some Daewoos with Suzuki badges here— the Verona and the Reno— while Chevrolet began selling the South Korean-built Daewoo Kalos as the Aveo for the 2004 model year. This car may not be a gem in the sense that you would want to own one, but it's a gem of automotive history and thus deserves its place in this series (especially because it's one of the rare 5-speed cars sold here). Many (maybe even most) of these cars ended up in the hands of rental-car companies and other fleet users, but we can tell from the three-pedal setup that this car went to a non-fleet buyer. We've had a couple of these cars compete in the 24 Hours of Lemons, where I work as a dignified and respected race official, and they've been amazingly quick on a road course in the hands of good drivers. Power came from this 103-horsepower Opel-designed four displacing 1.6 liters. The Nubira and Lanos got versions of this engine on these shores, too. The LS was the top trim level for the Aveo in 2004, so this car got air conditioning and a halfway decent audio system (by 2004 standards). The seat fabric is industrial-grade stuff, which would have held up well under the steady drip and/or torrents of bodily fluids coating the interiors of rental cars. The 2004 Aveo LS started at $12,045, which comes to about $16,675 in 2020 dollars, so it was a lot of commuter-appliance for the price. The following generation of this car became the Chevrolet Sonic, beginning with the 2012 model year. You can still buy a new Sonic, and the inflation-adjusted price is nearly identical to that of the original AveoÂ… though you might want to move fast if you really want one, because Daewoo stopped selling the Kalos in South Korea not long ago. If you want the rarest member of the Aveo family available in North America, find yourself a hen's-teeth Pontiac G3, the short-lived Pontiac-badged version. Speaking of the G3, here's the way it broke the hearts of gas pumps around the world.

Experimental mid-engine XP-819 Corvette going up for auction

It seems to be commonplace that when a new Corvette is in development, rumors swirl about a possible mid-engine layout. As is the case of Chevy's most recent C7 Corvette, these rumors never pan out.
In any case, the idea for a 'Vette with an engine mounted behind the driver can probably all be traced back to a single car, the 1964 XP-819 prototype. Built as an "engineering exercise" back in 1964, the prototype was designed with a rear-mounted engine. History tells us that the idea of a rear-engine Corvette fizzled, and the XP-819 was eventually cut up into pieces and stored at a shop in Daytona Beach, FL.
After sitting for untold years, a restoration project started on the car, and while it isn't yet fully completed, the current owner of the car, Mid America Motorworks, will have the car on display at the 2013 Amelia Island Concours d'Elegance as a "driveable chassis" with hopes of having a fully completed car ready to bring to next year's show.
