Next-gen Mazda MX-5 could use carbon fiber to cut weight

The current Mazda MX-5 Miata has only been out for a few years, but the automaker is allegedly looking for ways to lighten the next one. According to a report from Autocar, Mazda is looking to carbon fiber to help the next-generation MX-5 cut weight and use a smaller engine. Despite having more safety features, modern amenities, and a stiffer body, the current MX-5 is the same size as the original sports car from 1990 and weighs less than its immediate predecessor. In a recent interview with Autocar, Nobuhiro Yamamoto, head of the Miata program, revealed that the next generation of the Miata will probably stay the same size, but could be even lighter thanks to the utilization of carbon fiber. The current MX-5 uses high-strength steel and aluminum, and Mazda doesn't use carbon fiber in any of its cars. Carbon fiber is expensive to incorporate into road-going vehicles, and so Yamamoto notes that Mazda has been hard at work making it more affordable. A lighter car could result in a smaller engine, Yamamoto said. In the US, the MX-5 comes with a 2.0-liter four-cylinder engine that makes 155 horsepower, while the Japanese and European version comes with a 1.5-liter, 130-hp engine. A smaller engine would make the sports car even lighter. It's unknown at this time if the automaker is collaborating with another automaker or a supplier to make produce carbon fiber, or if it'll make it in-house. There's no word on how much carbon fiber the next MX-5 will wear or how it will affect the sports car's price. Autocar reports that the next MX-5 won't arrive anytime before 2021, which could make the ND MX-5's lifespan an unusually short five years long. With cars getting heavier, it's nice to hear that Mazda is working on finding a way to make its lightweight sports car even lighter.

Automotive Grade Linux will be the backbone of your connected car

Creating a backend for a secure, reliable, and expandable infotainment system is costly and time consuming. The Linux Foundation, a non-profit organization, has set out to promote and advance the Linux operating system in commercial products. Automotive Grade Linux, or AGL, is a group within the Foundation that seeks to apply a Linux backend to a number of automotive applications in a variety of vehicles from various suppliers and manufacturers. AGL's goal is to create a common, unifying framework that allows developers and manufacturers to easily implement applications across platforms. Currently, the focus is on infotainment systems, but AGL has plans for instrument clusters, heads-up displays, and eventually active safety software. At CES, a display from Panasonic showed a completely digital and customizable dashboard that allows information and apps to be moved from the gauge cluster to the infotainment screen and back, all through the use of gesture and touch controls. Although the organization has been around for five years, it's really only been in the past three that the group has been working hand in hand with automakers and suppliers. The first two OEMs to participate, Toyota and Jaguar Land Rover, have since been joined by Mazda, Suzuki, Ford, and, as of this week, Daimler. The latter is important as until now most of AGL's partner's have been based in Japan or the US. Other partners include suppliers Denso, Renesas, Continental, Qualcomm, and Intel. AGL want's to supply roughly 80 percent of the backend, allowing partners to then finish and refine the Linux system for each individual application. Think of how the Android operating system is refined and customized for individual smartphones from Samsung, LG, and Motorola. While the final product looks different, developers can have an application that will work across all AGL systems. Because it is open source, anyone can use and develop for AGL. You can even go onto the group's website and download a copy right now. There is also a software development kit available that helps facilitate app creation on the platform. Vehicle development cycles take roughly five years, so there currently are no cars that run an AGL backbone available for consumers. AGL Executive Director Dan Cauchy says products should be hitting the market later this year, with even more coming in 2018. Right now, the industry is relatively fragmented when it comes to infotainment and related systems.

Mazda CX-5 diesel gets EPA fuel economy ratings

Mazda has been promising that it will bring the Skyactiv-D diesel engine to the United States pretty much since the last Mazda6 redesign for the 2014 model year. And even in the wake of delay after delay, the company has insisted it will happen. Well, it looks like we may not be far from the fulfillment of this promise, since the EPA and DOT's FuelEconomy.gov website now has numbers for the diesel-powered Mazda CX-5. What's surprising, besides the existence of hard numbers, is that those numbers aren't actually that big of an improvement over the gas engine. In fact, highway numbers are the same as the gasoline versions. The front-drive CX-5 diesel gets 31 mpg on the highway, and the all-wheel-drive one gets 30 on the highway. The diesel does see improvements in the city. The front-drive model gets 28 mpg versus 25 for the gas equivalent. The all-wheel-drive model gets 27 mpg rather than 24 for the gasoline version. Also concerning is the fact that the CX-5 diesel isn't the only diesel in the segment. The Chevy Equinox is available with a diesel, too, and while city mpg is about the same, it can hit 38 mpg with all-wheel-drive and 39 with front-drive on the highway. With this in mind, Mazda will probably market the engine as more of a performance upgrade, and maybe something with a bit of extra towing capacity. This is because the engine is expected to make a bit over 170 horsepower and 310 pound-feet of torque. The power number is a smidge below that of the 187 from the 2.5-liter naturally aspirated gas engine, but the torque number is much higher than the gas engine's 186 pound-feet. We've also reached out to Mazda for comment on this development. A representative offered no further comment beyond the company staying committed to diesels. Related Video:
