2014 Mazda3 2.0L Hatchback officially rated at 40 mpg highway

The Environmental Protection Agency has spoken, and these are the miles per gallon numbers it has officially bestowed on the 2014 five-door Mazda3 hatchback with the SkyActiv-G 2.0-liter engine: 29 city, 40 highway, 33 combined when fitted with the six-speed manual; 30 city, 40 highway and 33 combined when equipped with the six-speed automatic.
Those numbers exactly match the fuel economy targets that Mazda had set for the car when optioned with the 2.0-liter Skyactiv-G with 155 horsepower and 150 pound-feet of torque. For comparison to other cars in the segment, the EPA numbers for the 2013 Honda Civic sedan are 28 city, 39 highway, 32 combined when its 140-hp, 1.8-liter four-cylinder is paired with the five-speed automatic. The Hyundai Elantra GT gets 27 city, 37 highway and 30 combined according to the EPA when its 148-hp, 1.8-liter four-cylinder is paired with either a six-speed manual or six-speed automatic transmission. The numbers for the 2014 Ford Focus aren't out yet.

Mazda, Suzuki, Yamaha — more vehicle data fabrication found in Japan

TOKYO — Mazda, Suzuki and Yamaha improperly tested vehicles for fuel economy and emissions, the Japanese government said on Thursday, revealing fresh cases of compliance failures by manufacturers. The results came to light after the Japanese government had ordered the automakers to check their operations after revelations of improper testing at Subaru and Nissan last year. The conduct of automakers globally has come under intense scrutiny after Germany's Volkswagen AG admitted in 2015 to installing secret software in hundreds of thousands of U.S. diesel cars to cheat exhaust emissions tests, and that as many as 11 million vehicles could have similar software installed worldwide. In the Japanese cases, the carmakers have not broken any laws or prompted massive recalls. But a growing list of improprieties has tarnished the image of the country's manufacturing industry for high-quality products and efficiency. Suzuki, Mazda and Yamaha cleared vehicles for emissions or fuel efficiency even in cases where they were tested under invalid conditions, the ministry said in a statement. The errors related to slight deviations in the speed of the vehicles during testing that should have invalidated the test results. The automakers examined tests they had conducted over different periods of time, and in Suzuki's case they stretched back to 2012. None of the automakers found significant problems with actual emissions and fuel economy performance of the vehicles, which were destined for sale in Japan, and do not plan any recalls. Suzuki, Japan's fourth-largest automaker, said that of 12,819 sample vehicles tested for fuel economy and emissions since June 2012, around 50 percent of them had been inspected improperly. "I deeply apologize and will lead efforts to prevent recurrence," Suzuki Chief Executive Toshihiro Suzuki told a news conference. Mazda said there were irregularities in 4 percent of similar inspections on its cars, or just over 70 vehicles. In Yamaha's case, irregularities were found in 2 percent of inspections, or just a handful of vehicles. Both Mazda and Yamaha apologized. Suzuki and Yamaha shares fell 6 and 5 percent, respectively, and Mazda shares were down 1 percent, underperforming a steady benchmark Nikkei average. In July this year, Nissan admitted it had improperly measured exhaust emissions and fuel economy for 19 vehicle models sold in Japan.

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.
