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.

Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

2017 Mazda CX-9 Prototype First Drive

If you read our coverage from last week's Los Angeles Auto Show, you'll note that we were extremely fond of the new Mazda CX-9. We like the look of the thing, inside and out, and it promises to be the best-driving entry in the three-row crossover class. We agree wholeheartedly with that claim. You see, we already drove it. Full disclosure: Our test of the camouflaged CX-9 prototype you see here was short, and while we were able to get a good handle on the CX-9's basic driving dynamics, it'll take more than a 30-mile session around the outskirts of LA to uncover the finer details. What's more, these vehicles are not production ready. In fact, according to our handlers at Mazda, the CUV we tested was actually at the stage before pre-production – so basically, a pre-pre-production car. That said, all the details about the engine, transmission, suspension, and steering are "largely final." As you can see in the gallery, the cars we tested were heavily camouflaged both inside and out. As for styling, we love it – see the undisguised pictures from the LA show for more views. And as for inside, we can say leather seats of our Grand Touring model were comfortable and supportive, and the smallish steering wheel felt natural in the hand. Even in pre-pre-production state, the CX-9 was impressively quiet. An extra 53 pounds of under-floor sound deadening, thicker windows, and active noise cancellation all contribute to what Mazda claims will be "among the quietest vehicles in its class." It's worth noting that the good sounds, like the throaty, whooshy noises of the turbocharged engine, found their way into the cabin just fine. The 2.5-liter, turbocharged four-cylinder engine – Mazda's first force-induced Skyactiv engine – is an excellent piece. The 2.5-liter, turbocharged four-cylinder engine – Mazda's first force-induced Skyactiv engine – is an excellent piece. It uses a variable geometry turbocharger, which the company calls a Dynamic Pressure Turbo. Here's how Mazda explains it: Imagine a normal garden hose. Put your thumb over the nozzle, and the force of the water increases dramatically. That's the DPT at low rpms. It features three small exhaust ports to direct exhaust gases into the turbo, making for 17.4 quick-spooling PSI at low rpms. As the revs climb, a flow control valve opens up, redirecting the gases to a trio of larger ports – removing your thumb from the hose, if you will – and keeping the boost up.
