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.

Mazda CEO says rotary not viable, so don't look for a new one

We have some very sad news to report, rotor-heads fans: Don't expect a new rotary-powered vehicle anytime soon. This comes straight from Masamichi Kogai, the CEO of Mazda, which is the only company to ever market a commercially successful rotary-powered automobile in the world. The issue, as it has pretty much always been, is environmental.
While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of fuel and emitting lots of noxious gases into the atmosphere, at least when running on gasoline. And that means the rotary engine will likely only ever be able to power niche vehicles. And that, in turn, means that it is very difficult to turn a profit on vehicles with rotary engines, particularly for a small automaker like Mazda.
"It has to be a viable commercial proposition. If we are going to adopt it, it has to be a product that can generate at least sales of 100,000 units a year. We have to be able to achieve a profit," said Kogai in an interview with Automotive News. Mazda sold 56,203 RX-7 models in the United States (the automaker's biggest market) in 1986. Sales of the RX-8 peaked in 2004, its first full year on the market, with just 23,690 units.

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:
