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.

The Chevrolet Camaro 1LE returns with V6 or V8 power

The Chevy Camaro's performance variants are legendary, and enthusiasts have long lusted after the Z/28 and ZL1. But there's a lesser-known model that shouldn't be overlooked: the 1LE. It's Camaro code for performance on the track. The 2017 Camaro 1LE debuts this week at the Chicago Auto Show and goes on sale late this year. The 1LE package will be offered for the first time on V6 Camaros, as well as the traditional V8-powered SS. The cars have upgraded suspensions, better brakes, aerodynamic treatments that create more downforce, and improved cooling features. The goal is simple: faster laps. "This is all grip and handling and cooling," said Todd Christensen, Camaro marketing manager. It's an enthusiast special, transforming your basic Camaro into a more capable track machine. The 335-horsepower V6 and 455-hp V8 are unchanged (and only come with six-speed manual gearboxes), because the focus is on improving the Camaro's reflexes. That means different things, depending on the engine choice. Here's how they break down. V6 1LE The V6's 1LE package is based on the LT trim and it pilfers the best chassis pieces from the V8 model, including the FE3 suspension with stabilizer bars. It also has a mechanical limited slip differential (3.27 ratio) and four-piston Brembo brake calipers in front. The fuel system is also borrowed from the SS, and it all rolls on 20-inch forged aluminum wheels wrapped in Goodyear Eagle F1 rubber measuring 245/40R20 in front and 275/35R20 in back. Christensen says Chevy added the 1LE pack for the V6 because customers actively wanted it, and for a reasonable price (we hear the 1LE will cost about the same as the fifth gen's $3,500 option) they can transform their V6 into a car that's as track capable as the SS. While it's giving up 120 hp, a V6 Camaro 1LE will also be more than 200 pounds lighter than the eight-cylinder 1LE. Chevy noticed the customer interest for a V6 1LE and will study offering the pack on Camaros with the turbocharged four-cylinder engine. Consider the V6 a test case. "I'm anxious to get some customer feedback [from the V6]," Christensen said. SS 1LE Even though it's heavier, the SS 1LE offers a lot of goodies that make it three seconds faster than a normal SS, according to Chevy's testing at Willow Springs Raceway in the California desert. The spotlight features in the SS are Magnetic Ride Control for the FE4 suspension and electronic-slip differential (3.73 ratio).

Corvette Stingray designer lists five goals of new exterior shape

Redesigning an icon is a difficult task, especially when you've got a blank sheet of paper in front of you and the all-new C7 Chevrolet Corvette Stingray is intended to be your final objective.
General Motors has released a new short video featuring Kirk Bennion of the Corvette's exterior design team, talking about the challenges of sculpting Chevrolet's new flagship sports car and the five goals the team had to keep in mind as it worked. In the end, Bennion's team had the pleasure of seeing their hard work take center stage as the Corvette captured the world's eyes at the Detroit Auto Show earlier this year.
