Mazda patents show rotary engine for range-extended EV
Fri, Mar 17 2017Two 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.
2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo
Fri, Oct 27 2023The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff. Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).

Mazda recalling 190,000 CX-7s due to rusty ball joints
Fri, Aug 26 2016UPDATE: This post has been updated with additional information from Mazda. The Basics: Mazda is recalling 190,102 Mazda CX-7 crossovers built between February 14, 2006, to May 9, 2012 – model years 2007 through 2012. The Problem: Water can sneak in between the suspension ball joint fittings. If snow and road salt are common in your neck of the woods, the joints can corrode and separate from the lower control arms. That's bad if you enjoy steering your CX-7. According to Mazda, owners of affected models may notice a rattle from the front suspension due to the loose ball joint in the lower control arm fitting. Mazda describes separation of the ball joint and control arm as a "worst case" scenario "after extended operation in such condition." Injuries/Deaths: It's unknown if the rusting issue has led to any crashes, injuries, or deaths. Autoblog has a call into Mazda for additional details and will update this post with any new information. There have been no reports of accidents, injuries, or fatalities related to this recall. The Fix: Owners should report to their local Mazda service center, where techs will replace the both front lower control arms. Any work done is free of charge. If you own one: Mazda will perform some automotive triage with this recall, focusing on CX-7s that have had the longest exposure to salt and are most likely to suffer control arm separation first. Owners of 2007s and 2008s come first, followed by 2009 through 2011 models. Mazda will also focus on vehicles registered in states where snow and road salt are most common – Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington, D.C. If you live in a more temperate region or own a 2012 CX-7, Mazda will perform recall work as "parts are available." Owners can contact Mazda customer service at 1-800-222-5500 for additional info. Recall notices should hit the mail around October 10th.
