Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.

MotorWeek finds nice things to say about the 1993 Ford Probe

This latest in MotorWeek's series of Retro Reviews continues its recent trend of remembering the massive glut of sports coupes that hit the market in the '90s. While vehicles like the Mitsubishi 3000GT, Mazda RX-7, and Ford Mustang all enjoy solid reputations down to this day, the 1993 Ford Probe, well... doesn't. As you'll soon see, though, the show's opinion suggests the coupe's second generation isn't really all that bad. Turns out they just weren't particularly sporty. Ford and Mazda developed the Probe together, and the Japanese company supplied both the base 115-horsepower 2.0-liter four-cylinder and the 164-hp 2.5-liter V6 in the GT trim. The original's pseudo-angular look gave way to a much smoother shape for the second generation. Of course, pop-up headlights remained, which were a design hallmark for many of this era's sports coupes. After driving it, MotorWeek proclaims the Probe is "a winner" and considers the handling a "delight." That's not a big surprise, considering that in those days, a car had to be really bad not to get a decent review from Television's Original Automotive Magazine. However, the show hints at some of the reasons the coupe isn't so well remembered today. Even the GT reportedly suffers from soft springs and lots of understeer, which sounds like exactly the opposite anyone hoping to drive the coupe enthusiastically would want. To sum it all up, we're sure you're just as happy as we are that Ford went back on its initial plan to shelve the Mustang in favor of the front-drive Probe. Related Video:

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.
