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.

Weekly Recap: Bentley Bentayga leads luxury SUV charge at Frankfurt

The Bentley Bentayga is launching a new era of ultra high-end sport utility vehicles that will see luxury makers vie for the world's richest and most exclusive customers. The Bentayga is Bentley's first SUV, and it will formally debut next week at the Frankfurt Motor Show. It's loaded with Bentley's best technology and features, led by a 600-horsepower W12 engine. The mission is simple: stop giving up sales to other companies by not having an SUV in its portfolio. "It creates an entirely new category of ultra-luxury SUV, where there are currently few rivals," IHS Automotive analyst Ian Fletcher said in a report. But Bentley and the Bentayga will soon face stiff competition. Archrival Rolls-Royce will produce its own crossover to be built in England, though timing is unclear. Lamborghini has approved plans for a ute that will be assembled in Italy and launch in 2018. Even the sportier British brands are getting into the market. Aston Martin will make a crossover version of the DBX concept shown earlier this year in Geneva, and Jaguar is launching the F-Pace crossover, which will debut in Frankfurt. These new entries will invigorate a segment that's comprised of the Mercedes G63 AMG and the Land Rover Range Rover SV Autobiography, and Bentley is poised to grab a large share of it, Fletcher noted. IHS forecasts Bentayga sales could hit 3,000 units per year in 2017 and 2018, pushing total Bentley sales to more than 10,000 in the next few years. The vehicle will also get plug-in hybrid and diesel variants to widen its reach. The Bentayga is a sales grab, for sure, but Bentley took care to ensure the SUV remained true to the brand. It's laden with the top-shelf wood, leather, and metal, and it comes standard with an expansive panoramic glass roof. It also has intelligent features like electronic night vision and an optional responsive off-road system that can be configured to adapt to eight different settings. It's a different kind of Bentley, but it's a harbinger of things to come for the world's richest luxury makers.

The car promises 10-percent gains in fuel efficiency, though actual figures – and even powertrain specifics – were not revealed. We estimate that could mean about 56 miles per gallon in city driving and 53 on the highway.

The Tesla Model S was the best-selling EV of 2015

According to numbers crunched over at Hybrid Cars, the Tesla Model S was the best selling pure electric vehicle last year with 50,366 deliveries. These numbers might not tell the whole story, since Tesla reports deliveries made in 2015 that might have been sold in a different calendar year, while other makers are tallying sales. However, it's inarguable that the Model S ended up in more worldwide driveways than the second-place Nissan Leaf, which did about 43,000 sales. In the US alone, Leaf sales were down 42.8 percent year-on-year, from 30,200 in 2014 to 17,269 last year, and that decline also increased throughout the year. That marks a great finish to a great start to 2015, when Tesla took the lead in EV sales in the US for the first quarter. On top of that, as of last year the Model S becomes the second-best selling EV ever, with 107,148 deliveries since the middle of 2012. It trails the Nissan Leaf, with well over 200,000 worldwide sales. The Chevrolet Volt/Opel Ampera combo takes a close third, with about 106,000 sales. The Nissan and Chevy rivals both launched at the end of 2010, a 16-month head start on the Tesla. Down the charts, the Mitsubishi Outlander PHEV which continues to be forbidden fruit for our market notched 39,000 sales. The BYD Qin PHEV sold 31,898 examples in China, and BYD would take the overall victory from Tesla with 58,728 deliveries if you counted all of its EV and PHEV production, such as its electric buses. The BMW i3 nabbed fourth place with 24,057 global sales. In 2011 the Munich automaker said it wanted to sell 30,000 i3s annually by 2014, but by the time the car launched the company considered 15,000 annual sales 'great for now,' so the 2015 number seems a fine place to wind up.
