Recharge Wrap-up: 61 miles on Autopilot; Mazda CX-9's 32% mpg improvement

A technology analyst at The Motley Fool used Tesla's Autopilot uninterrupted for 61 miles. In order to see how far the Tesla Model S could drive itself without driver intervention, Daniel Sparks set off on the highway from Monument, Colorado, through Colorado Springs and onward toward Pueblo. Only when a truck encroached on his lane did the driver take command of the wheel, rather than waiting to see what the car would do. "With [the] Model S nearly out of Pueblo and onto a long, boring stretch of highway by the time I had to grab the wheel, chances are I could have made it all the way to Colorado City if it wasn't for this interruption," says Sparks. Read the full account at The Motley Fool. The 2016 Mazda CX-9 offers 32 percent better fuel economy than the outgoing model. The front-wheel-drive CX-9, equipped with Mazda's Skyactiv-G 2.5T engine, gets an EPA-estimated 22 mpg city/28 mpg highway/25 mpg combined. The 2016 CX-9 has shed significant weight compared to its predecessor. Its turbocharged engine uses a Dynamic Pressure Turbo system, which improves performance at lower rpm by controlling the degree of exhaust pulsation according to engine speed. The new CX-9 goes on sale this spring. Read more at Green Car Congress. A group of eight US cities have formed the Energy Secure Cities Coalition (ESCC), pledging to switch their fleets over to alternative fuels. Atlanta, Charlotte, Indianapolis, Orlando, Rochester, Sacramento, San Diego and West Palm Beach will retire their petroleum-powered vehicles in favor of EVs and cars using cleaner fuels like natural gas. The cities expect the change to help improve air quality and save taxpayer money on fuel and maintenance costs. The ESCC hopes to grow to include 25 major cities, removing some 50,000 petroleum-fueled vehicles from service and saving 500,000 barrels of oil per year. Read more in the press release below.

2019 Mazda3 gets only two engines in U.S.; here are details on suspension, AWD

We learned a lot about the 2019 Mazda3 hatchback and sedan when it made its debut at the L.A. Auto Show. It will still have a manual transmission, it will offer all-wheel drive for the first time, and it's a stunner inside and out. But we still had questions about some of the details, so we spoke with folks from Mazda, including a couple of engineers for details on engines, suspension and drivetrains. First off, of the five engines announced for the Mazda3, just two of them are slated for the United States. At launch, the Mazda3 will be offered only with a naturally aspirated 2.5-liter four-cylinder. It's mechanically pretty much the same as what you'll find in the Mazda CX-5 and Mazda6. It even features cylinder deactivation. The only real difference between this engine, its predecessor, and the one in other Mazdas is some minor engine tuning tweaks. Power is almost the same with 186 horsepower and 186 pound-feet of torque, gains of 2 horsepower and 1 pound-foot. Fuel economy is rated at 27 mpg in the city, 36 on the highway, and 30 overall for front-wheel-drive models. We would expect the all-wheel-drive model to have slightly worse fuel economy simply due to extra weight and having to power two extra wheels. The Skyactiv-X engine will become available later in 2019. It will be rolled out in Europe first, with America coming after. When it does come here, it will be offered in states with stricter emissions regulations before coming to other states. While we're on the topic of engines, we also probed a bit about the possibility of the turbocharged 2.5-liter engine coming to the Mazda3. We did get the typical response of not being able to comment on future product. However, they did confirm that the turbocharged engine does in fact fit in the new Mazda3, since it and the naturally aspirated engine are very similar, and the naturally aspirated engine still uses an enormous header, meaning turbo plumbing wouldn't be an issue. Everyone we spoke with at Mazda did emphasize that they are listening closely to buyers, which is what led to the turbo engine being offered on the Mazda6 and CX-5, as well as the introduction of all-wheel-drive to the Mazda3. So, if you, like us, want to see the turbo engine added to the Mazda3, let the company know. They might just do it. Now as for drivetrains, the company is still deciding which trims and which combinations of engines will be offered.

Weekly Recap: GM plans massive new paint shop at Chevy Corvette factory

General Motors is laying out some serious green to maintain the Chevy Corvette's expansive color palette. The automaker is breaking ground on a new paint shop this summer that's part of a $439-million investment to upgrade the 34-year-old Bowling Green, KY, factory that builds the Stingray. The massive new structure will total 450,000 square feet, nearly half the size of the current 1-million square-foot facility. Construction is expected to take two years and won't impact Corvette production. The upgrades include new robots that save paint and create a better finish, longer, more efficient ovens to bake in the finish, and LED lighting. There's also a dry scrubbing booth technology with a limestone handling system that eliminates waste. GM has invested $135 million in the factory in last four years for the changeover to build the C7 and to relocate its Performance Build Center to Bowling Green. The improvements continue to modernize the Kentucky factory, which has become a tourist attraction in its own right, as more than 56,000 enthusiasts visited it last year. The upgrades are part of a $5.4-billion investment GM confirmed in April that will remake its US footprint in the next three years. The Bowling Green expansion underscores GM's continued commitment to the Corvette, which sold nearly 38,000 copies around the world last year, an eight-year high. "With this major technology investment, we can continue to exceed the expectations of sports car buyers for years to come," North American manufacturing manager Arvin Jones said in a statement. OTHER NEWS & NOTES Takata recall hits 34 million vehicles The National Highway Traffic Safety Administration expanded the Takata airbag recall to an almost unthinkable 34 million vehicles on Tuesday. The recall is part of an agreement reached by the two sides where Takata admitted some of its airbag inflators have a defect, and the deal compels the company to comply with all future regulatory actions and investigations. Takata's airbag inflators were produced with "a propellant that can degrade over time" and lead to ruptures, NHTSA said. Six deaths have been attributed to the flaw worldwide. Investigations conducted by Takata, automakers, and others have not determined the exact cause of the inflator problem, but NHTSA said moisture appears to alter the propellant's chemical structure. It then ignites too rapidly, creates too much pressure that ruptures the inflator, and blasts shards of metal at passengers.
