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.

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.

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.

2019 Mazda CX-5 debuts with turbocharged engine and near-$40K price tag

We've seen a couple different leaks concerning the 2019 Mazda CX-5, but now Mazda finally has official word on what's coming our way. One exciting development is the addition of the 2.5-liter turbocharged four-cylinder engine on higher trim levels. It's great to see Mazda sharing that engine to other models after originally debuting in the larger CX-9. In the CX-5, it makes 250 horsepower and 310 pound-feet of torque on 93 octane. To get the boosted engine, you'll have to opt for one of the two new trim levels Mazda has added for 2019: Grand Touring Reserve or Signature. Of course, with higher trim levels and more powerful engines come higher prices. The Signature trim comes in at a whopping $37,885 including destination charges. For 2018, the highest trim level available was the Grand Touring, and that car costs $30,640. Mazda adds a bunch of new features for the expensive Signature trim, though. You'll get brown leather seats, real wood trim, a uniquely stitched leather steering wheel, 360-degree view camera, a frameless auto-dimming mirror, LED lighting throughout the interior and dark silver 19-inch wheels. These options are in addition to the new and still luxurious Grand Touring Reserve trim level. This trim has heated and cooled seats, a heated steering wheel and power folding mirrors as its highlights. For comparison, the Grand Touring Reserve with the turbocharged engine costs $35,865. Making the CX-5 more luxurious wasn't the only aim for 2019 — Mazda also gave it a new version of its G-Vectoring Control handling system. The updated G-Vectoring (now called G-Vectoring Control Plus) helps when the driver is unwinding the wheel by "adding a hit of braking to the outside front wheel," according to Mazda. This, in addition to some suspension refinements, are supposed to make for a smoother and better ride. Specifically, Mazda says it re-tuned the suspension to reduce friction and adjusted the steering geometry to achieve more natural feeling handling. Sweating over these small handling and feel things is why we typically end up liking the driving experience of Mazda vehicles. Mazda increased prices on the CX-5 across the board, too. The Sport trim is $1,600 more than before, with other trims following suit at similar increases. We'll see how the changes affect the sporty and now more expensive crossover when we get our hands on a 2019 model. For now, you can build them on Mazda's website, and Mazda says they'll be available sometime this fall.
