Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.

Mazda recalling 190,000 CX-7s due to rusty ball joints

UPDATE: 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.

2015 Mazda3 finally pairs 6-speed manual with larger engine

With all of the hype and anticipation surrounding the 2016 Mazda MX-5 Miata, the Japanese brand was able to sneak another driver-oriented model into its lineup. The company's spec page for the 2015 Mazda3 hatchback and sedan have been updated to list the Skyactiv-G 2.5-liter four-cylinder as finally being available with a six-speed manual transmission, in addition to the previous six-speed automatic. The automaker had promised the row-your-own gearbox with the bigger engine back when it first announced the new Mazda3, but it waited a model year to actually put the combo on sale.
According to Mazda's specs, the manual gearbox trims 40 pounds off of a hatchback or 54 pounds off of a sedan in s Touring and s Grand Touring trims. However, shedding that weight doesn't necessarily boost fuel economy. The six-speed hatch is rated at 26 miles per gallon city and 35 mpg highway, compared to 27/37 for the automatic. The manual sedan is rated at 25/37 city/highway mpg, versus 28/39 with the auto. Buyers can save a little money by opting for the manual, though. Regardless of body style, it's about $1,050 cheaper than the automatic.
Autoblog reached out to Mazda and learned that the 2.5L 6MT models started hitting dealers in August. The 2.5 wasn't initially available with the stick because, "We had to prioritize engineering resources and the 2.5L 6MT was not a high priority combination. Globally, smaller engines are preferred in terms of sales," a Mazda spokesperson explained via email. The automaker also notes that Austrailia will probably be the only other market outside of North America to get the six-speed gearbox with the larger engine.
