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.

Mazda CX-30 Luggage Test | How much cargo space?

The Mazda CX-30 is pretty much a lifted Mazda3 hatchback. Same platform, awfully similar dimensions, and the interior's a spitting image (if not identical). Ditto cargo capacity. On paper, the two have virtually the same amount of space behind their raised back seats, with the CX-30 at 20.2 cubic-feet and the 3 with just a teensy less at 20.1.  Now, before I go any further, let's see how much that 20.1 cubic-feet relates to in the Mazda3. I wasn't yet doing this test format back then, hence the video.  For reference, both tests used my standard luggage selection of two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). The bag of baseballs shown in the video is slightly smaller than my new small-bag go-to, my wife's fancy blue overnight bag (21L x 12W x 12D). So, the mark to beat is therefore all the bags minus the smallest roller.  Here is what 20.2 cubic feet looks like in the CX-30. To move beyond the Mazda3 comparison, that figure is in keeping with the CX-30's niche placement between subcompact (the teens) and compact SUVs (upper 20s to upper 30s). The Mazda CX-5 has 30.9 cubic-feet.  Now, typically, I start off by seeing how much I can fit inside with the cargo cover in place. Sadly, this particular CX-30's cargo cover is missing. We'll just have to hope it doesn't rob the CX-30 of as much space as the CX-5's does.  First off, it's immediately noticed that the CX-30's cargo area is not as long as the 3 hatchback's. The largest bag just barely squeezed inside, whereas there was some room to spare in the 3. Now, let's keep loading.  Whattya know? All of the roller bags fit inside. That includes the smallest one, which didn't fit in the 3, fitting atop the stack with perhaps 30% of it over the back seat line. Now, I could've done the same Tetris stack in the 3, but I'm virtually certain the hatch wouldn't have closed. Advantage, then, to the CX-30 and its extra height.  And surprise, the fancy bag also fits. Technically. It robs rear visibility, is pretty far above the seat line and it just barely fits under the back light. If it was filled, I have my doubts about its inclusion. Nevertheless, with or without it, there's still a bit more space on the right side for that bag of baseballs.  Now let's discuss the power liftgate.

Next-gen Mazda MX-5 could use carbon fiber to cut weight

The current Mazda MX-5 Miata has only been out for a few years, but the automaker is allegedly looking for ways to lighten the next one. According to a report from Autocar, Mazda is looking to carbon fiber to help the next-generation MX-5 cut weight and use a smaller engine. Despite having more safety features, modern amenities, and a stiffer body, the current MX-5 is the same size as the original sports car from 1990 and weighs less than its immediate predecessor. In a recent interview with Autocar, Nobuhiro Yamamoto, head of the Miata program, revealed that the next generation of the Miata will probably stay the same size, but could be even lighter thanks to the utilization of carbon fiber. The current MX-5 uses high-strength steel and aluminum, and Mazda doesn't use carbon fiber in any of its cars. Carbon fiber is expensive to incorporate into road-going vehicles, and so Yamamoto notes that Mazda has been hard at work making it more affordable. A lighter car could result in a smaller engine, Yamamoto said. In the US, the MX-5 comes with a 2.0-liter four-cylinder engine that makes 155 horsepower, while the Japanese and European version comes with a 1.5-liter, 130-hp engine. A smaller engine would make the sports car even lighter. It's unknown at this time if the automaker is collaborating with another automaker or a supplier to make produce carbon fiber, or if it'll make it in-house. There's no word on how much carbon fiber the next MX-5 will wear or how it will affect the sports car's price. Autocar reports that the next MX-5 won't arrive anytime before 2021, which could make the ND MX-5's lifespan an unusually short five years long. With cars getting heavier, it's nice to hear that Mazda is working on finding a way to make its lightweight sports car even lighter.
