Mazda to use rotary engine as a range-extender with its first electric vehicle

There's more news from Mazda at the Tokyo Motor Show, where the brand made a big splash, including new developments in its never-ending rotary engine saga. First, Mazda execs confirmed that the Japanese automaker will bring back the rotary engine as a range-extender and battery juicer for its first electric vehicle in 2019. But secondly, the company won't have a rotary-powered successor to its RX-7 and RX-8 sportscars in time for the company's centennial anniversary in 2020. Autoblog previously confirmed that Mazda is planning to have an EV in 2019 that will be available in both pure electric and range-extending versions. Now, the Australian website Motoring reports that the global EV will feature a powertrain similar to the experimental Japan-only Mazda2 (Demio) EV, which used a single-rotor engine as a generator to power the battery pack and increase its driving range. The publication says Mazda plans to release a series of plug-in hybrids based on existing models around 2020, then a pure electric car co-developed with Toyota and Denso in 2021 as part of the EV Common Architecture Spirit Company joint venture. A Mazda spokesman tells Autoblog the company couldn't confirm any details about future products. Meanwhile, enthusiasts shouldn't wait for a rotary-based production version of Mazda's RX-Vision concept from 2015. Motoring cites two executives who explain that the company simply lacks the capital necessary to invest in developing the new model in time for its 2020 centennial. Mazda debuted its rotary engine 50 years ago in the Cosmo Sport in part as a way to stand out from its larger Japanese competitors. The engine, which uses a spinning three-tipped rotor in place of pistons, is smaller and lighter than conventional piston engines, with a greater power-to-weight ratio and quieter, smoother operation. But it delivers less fuel economy and higher emissions — two weaknesses that could be improved via a stop-start system Mazda has developed, based on a pair of U.S. patents. The company has also been hard at work developing its next-generation Skyactiv-X engine, which uses highly precise combustion ignition technology to deliver significant gains in fuel economy and power.Related Video:

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:

Miata buyers prefer a manual gearbox, says Mazda

Earlier, we wrote about Toyota's underwhelming 2018 manual transmission sales figures. To recap – as Toyota's representatives told CarBuzz – the automatic Corolla outsold its manual equivalent to a ratio of 100 to 1, and just one in three Toyota 86 buyers picked a manual version of the rear-drive coupe. What about the other famous rear-wheel-drive offering from Japan, Mazda's MX-5 Miata? A case can be made that an 86 buyer cross-shops the Miata, and vice-versa, but what kind of split do Mazda's sales figures reflect in comparison? We reached out to Mazda for some sales data, and PR program manager Tim Olson told us 76 percent of Miata soft-top buyers go for the classic stick-shift option, leaving just 24 percent of buyers preferring the automatic. Both transmission options for the Miata are six-speed. The figures are based on year-to-date sales data for the 181-hp 2019 Miata, from July 2018 through April 2019. Interestingly, the more coupe or targa-like, retractable hardtop RF variant takes a step towards the 86 when it comes to transmission choices. While RF buyers still preferred the manual, the split was far closer to half and half: 52% went for the manual, and 48% chose the automatic. Perhaps this reflects the RF's more grand tourer-like image, and it might also be indicative of the RF's higher pricing. If you're going to spend nearly $34,000 for a Miata, another $600 for an autobox doesn't necessarily mean that much – choosing the auto on the base, Sport trim level soft top roadster is a $1,350 bump instead. While the $26,650 base Sport isn't exactly spartan, on a roadster it's fine to have less cushiness. With the higher-specced Club trim level, the auto's price tag shrinks to the aforementioned $600, as it is on the RF Club. There's no base Sport for the RF, as the cheapest RF is the $33,865 Club. But still, the manual shifter's snick-snack feel is one of the Miata's classic traits that has been with it since its inception 30 years ago. Sources say fewer than 5% of the original first generation Miatas were made with an automatic gearbox, but it's obvious trends and tastes are changing – although to be fair, automatics are getting much better as well.
