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 recalls 374,500 vehicles because of Takata inflators

The Basics: Mazda will recall 374,519 examples of the 2003-2008 Mazda6 manufactured from May 29, 2002, to May 5, 2008; the 2006-2007 Mazdaspeed6 built from July 1, 2005, to June 29, 2007; and the 2004 RX-8 made from June 25, 2003, to June 30, 2003. The Problem: These vehicles contain front passenger airbag inflators from Takata that could rupture in a crash. If this happens, it could spray metal shrapnel at an occupant, which could seriously injure or even kill the person. Injuries/Deaths: The report from the National Highway Traffic Safety Administration didn't mention injuries or deaths, but Autoblog reached out to Mazda for confirmation. Takata's rupturing inflators allegedly have links to nine deaths globally and around 100 injuries. The Fix: Mazda dealers will replace the passenger side airbag with a new one. If You Own One: Mazda has not said when the replacements for these vehicles will begin. Experts believe that prolonged exposure to high humidity can cause the inflators' ammonium nitrate propellant to ignite too quickly in an accident. More Information: This recall is a nationwide expansion of Mazda's passenger's side airbag recall, which was previously limited to high-humidity regions. The population now includes 310,592 additional examples of the Mazda6, Mazda spokesperson Tamara Mlynarczyk tells Autoblog. The company discovered this new issue after Takata tested an inflator taken from a Mazda6, and it ruptured, according to NHTSA documents (PDF). The company already had a national safety campaign to fix the driver's side airbags in these vehicles.

The inflators in the front passenger air bags are susceptible to rupture in the event of a crash necessitating the deployment of the front passenger air bag.

2019 Mazda CX-5 Signature AWD diesel unveiled in New York

NEW YORK —It seems like we've been waiting forever, but the wait is finally over. Mazda has finally launched a diesel version of the CX-5 for the U.S. market, unveiled at the 2019 New York International Auto Show. Specifically, the 2.2-liter Skyactiv-D turbo-diesel engine will be offered in the higher-end CX-5 Signature AWD, part of what Mazda calls its "path to premium," as the company continues to set its sights on some of the more expensive competition. The Skyactiv-D 2.2 makes use of a sequential twin turbocharger that employs a smaller turbocharger first at low rpm for quick throttle response, after which a valve opens to spool up a larger turbocharger at higher rpm. Mazda says this provides "smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque." Mazda estimates the output of the engine to be 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm. The engine has a rev limit of 5,500 rpm. As of right now, it's only in the all-wheel-drive version and only in the Signature trim level. As such, it gets a ho-hum EPA fuel economy rating of 27 mpg city, 30 highway and 28 combined. We previously saw fuel economy figures for a potential front-drive diesel CX-5 getting just slightly better fuel economy, at 28 city, 31 highway and 29 combined, but no word yet on if and when that'll be made available. The mediocre diesel fuel economy, while expected given the midstream shift from one emissions strategy to another, is particularly disappointing in context. The non-turbo CX-5 AWD, which makes 187 hp and 186 lb-ft, gets 24 city and 30 highway for 26 combined mpg – just 3 mpg less in the city and 2 mpg less overall than the diesel. The much more powerful CX-5 Turbo, which makes 250 hp and 310 lb-ft, gets 22 city, 27 highway, and 24 combined. Mazda is taking pre-orders for the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 starting now, at an MSRP of $42,045, including $1,045 in destination fees. We have to point out that this is a sizable jump in MSRP from a CX-5 Signature AWD with the more powerful turbo engine, which lists for $38,235 – a $3,810 difference in fact. Given the lackluster fuel economy and considerable decrease in power and torque, we're concerned that the diesel may be a tough sell at this sort of premium.
