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.

2019 Mazda3 Review and Buying Guide | Redesigned and exceptional

The Mazda3 has long been a darling of car enthusiasts for its sharp styling and sharper driving dynamics. So when it was redesigned for 2019, there was some collective anxiety as to whether Mazda could continue the magic. From our experience, Mazda certainly has, and has improved its compact sedan and hatchback in many areas such as design and refinement. As a result, the 2019 Mazda3 is easily the most fun car in its segment to drive, barring specifically performance-oriented compact models, and now has materials and looks to rival entry-level luxury cars. Its only real faults are a slightly tight interior and a character that might put off fans of cushy cruisers. What's new for 2019? Pretty much everything. The Mazda3 has been completely redesigned for the 2019 model year. It's down to one engine for now — a lightly updated 2.5-liter naturally aspirated four-cylinder with or without cylinder deactivation — but a high-efficiency spark-controlled compression-ignition engine is coming later. And for the first time, the Mazda3 has available all-wheel drive on both sedan and hatchback body styles, making it one of only two cars in the segment with such a feature. 2019 Mazda3 AWD View 24 Photos What's the Mazda3's interior and in-car technology like? While the interior of the previous Mazda3 was one of the finest in the segment, the new model is vastly superior. In fact, it feels about on par with actual luxury cars in the top Premium trim. The dashboard has a sleek, modern look with subtle air vents, surfaces wrapped in a soft leather-like material, and an elegant steering wheel has nicely integrated buttons. All of the switchgear has a solid, crisp feel. The driving position is excellent, allowing the driver to sit either low or high and keeping all the controls and displays perfectly centered. Mazda also redesigned its infotainment system for this car. A major change is that there is no touchscreen functionality whatsoever, which is also partly why Mazda has moved the infotainment screen farther up the dash and more into the driver's line of sight. The entire menu layout has been revamped as well with options listed vertically instead of horizontally. The system runs substantially faster and smoother than the previous version, though it's not as easy to use due to additional layers of menus. It still isn't as complex as systems found in German cars, though. Mazda has also finally made Apple CarPlay and Android Auto standard features. How big is the Mazda3?

Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.
