Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

2020 Mazda CX-5 adds torque to the turbo engine, gets more expensive

The 2020 Mazda CX-5 is getting a little more desirable in the new model year. It’s also slightly more expensive. Most of the benefits are realized with the 2.5-liter turbocharged four-cylinder. This engine gets a small boost in torque, going from 310 pound-feet to 320 pound-feet. Horsepower stays the same at 250 horses, and the max power is still made using 93 octane fuel. We saw a similar torque gain in the 2020 CX-9. Mazda says it also added a new “Engine Harmonics Enhancer” that “tunes to the engine with a much more refined and powerful sound.” WeÂ’re guessing the turbocharged engine is going to sound just a hair better in 2020. When equipped with the turbocharged engine and all-wheel drive, the CX-5 also gets an off-road traction assist feature. Similar to the CX-9Â’s system, Mazda says “when the diagonal wheels lose traction, off-road traction assist will stop reducing the engine torque and increase the brake force on the wheels without traction.”  Mazda says all CX-5s will also take advantage of improved NVH, making the CX-5 feel a bit more premium and isolated from the road. Every CX-5 will also be equipped with MazdaÂ’s suite of i-Activsense safety features as standard in 2020, as well. This means adaptive cruise control and lane-keeping assist are both standard features now. As Mazda tries its best to move into the premium space, itÂ’s changed all the fonts on the badging and displays on the car. Although, Mazda neglected to include any photos of the new look, so weÂ’ll wait to judge on that front. The premium look and feel comes with a slightly higher price than 2019. A base Sport is $740 more expensive than last year, coming in at $26,135 after the $1,045 destination charge. The most luxurious Signature trim is just a touch more expensive than last year (by $165) at $38,100. What Mazda hasnÂ’t included in its 2020 rundown is the Skyactiv-D diesel option. WeÂ’ve reached out to Mazda to see if we can determine its fate in 2020 and will update this story upon hearing back. Update: Mazda responded to our request for comment. Since the 2019 diesel variant was on a different release schedule than the rest of the 2019 CX-5 lineup, the company isn't talking 2020 diesel yet. The company is treating it as a "future product," therefore it's not commenting on it.  We can only speculate as to what that means for the diesel CX-5, so we'll wait on official information from Mazda whenever it may come.

Mazda ad showing Facebook updates while driving criticized by Senate committee [w/video]

Senate Commerce Committee Chairman Jay Rockefeller, D-WV, held an all-day summit on Thursday to discuss the dangers of using modern technology while driving, during which an ad that Mazda aired during the Super Bowl was used as an example of the worrisome future towards which we're headed. While seemingly innocuous at first glance, the ad, which can be seen below, shows a brief glimpse of a driver using the Mazda Connect infotainment system in a Mazda3 to check/update his Facebook page while driving down the road.
Officials from major communications companies like Samsung, Google and Apple attended the summit, as well as representatives from automakers including General Motors and Toyota. A representative from Mazda was not present despite the company's own currently available technology being used as the poster child for the issues being discussed.
According to Automotive News, Senator Rockefeller warned the automaker and communication execs on hand that he will propose legislation to regulate the use of technology while driving if they don't work together to implement their own standards more quickly. Michael Robinson, GM's vice president of sustainability and global regulatory affairs, argued that his company has had distracted driving guidelines in place for 15 years since the advent of its OnStar system, noting that the technology in question has also helped the automaker save lives through automatic crash detection and calls to 911.
