Mazda 3 Sedan and Hatchback Luggage Test | Trunk comparison

A major reason for buying a hatchback is for added cargo space and versatility, right? Seems logical enough. It's certainly a reason I've been fond of them over the years. And since so many SUVs these days are just glorified hatchbacks, it certainly stands to reason the buying public has reached this conclusion as well. To test this hypothesis and potentially bust this myth, Mazda kindly provided three vehicles that are virtually identical apart from their body style: the Mazda 3 sedan and hatchback, as well as the Mazda CX-30 crossover that's really just a raised and rebodied 3.  On paper, in descending order, the CX-30 is tops at 20.2 cubic feet of space behind the back seat, the Hatchback has 20.1 cubic feet and the sedan has 13.2. OK, let's see how the order turns out once luggage is used. Here is the 3 Hatchback on the left and 3 Sedan on the right. Immediately, the sedan doesn't look that much smaller than the Hatchback. Actually, doesn't it look bigger? Below is the CX-30.  Note that this CX-30 did not include its rigid cargo cover, but already, you can start to see the difference between 3 Hatch and CX-30. The crossover has more space above the back seat line than the Hatchback. So, even if the 3 Hatch has more cargo area length, the CX-30 has more height. That's why you have virtually equal cargo capacity numbers despite having different spaces.  To that point, let's bring in the bags. As in every luggage test I do, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D). CX-30 for the win (above right) as all the bags fit. The fancy bag and smaller roller are slightly blocking the rearward view, but you can still see out and the bags won't fly forward. Importantly, they also fit when closing the CX-30's hatch. They won't if you attempted the same formation in the 3 Hatchback, which can't fit the fancy bag or one of the midsize rollers. And no, you can't fit the fancy bag in the middle there — the hatch wouldn't close on top of it. A smaller duffel will, however.  So, although the 3 Hatch has a slightly longer space, the difference doesn't matter as much as the CX-30's extra height in this usage case.

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.

Automakers are offering more fuel-efficient cars than ever

Even with gas prices near their lowest point in more than a decade, Americans are still concerned about the fuel economy of their cars. More than 4 in 5 consumers say gas mileage will be an important consideration the next time they go shopping for a vehicle, according to the results of a new survey conducted by the Consumer Federation of America, which were released Monday. That's no surprise, says Jack Gillis, director of public affairs for the nonprofit organization. "Consumers have had a long history with volatile gas prices," he said. Though motorists have saved approximately $12 billion this year at the pump compared to 2015, according to AAA, car shoppers expect gas prices to rise again in the future. The average respondent to CFA's survey predicted a price of $3.50 per gallon within the next five years, a figure in line with projections made by the US Energy Information Administration. When those consumers visit dealerships, they'll have plenty of options. More models than ever are achieving 30 miles per gallon or more, according to CFA's annual analysis released in conjunction with the survey, and 15 of 16 major car companies improved their fuel efficiency on their 2016 model-year offerings. Only Ford backslid year over year, per the report. Researchers say American consumers are now enjoying the widest range of fuel-efficient options ever offered, in every vehicle class. Of 1,094 models on sale in 2016, 13.4 percent achieved more than 30 MPGs, an improvement from 11.7 percent in 2015. At the same time, the percentage of gas guzzlers offered for sale has declined. The percentage of vehicles on the market that get 16 miles per gallon or less has fallen from 6.1 percent to 4 percent, says CFA. "Even if you're in the market for a large pickup or SUV, you'd have to go out of your way to find a true gas guzzler," Gillis said. ""Consumers have had a long history with volatile gas prices." – Jack Gillis These results, the CFA suggests, indicate federal standards that prod automakers to invest in fuel-efficient technology are having the desired effect. Manufacturers are keeping pace with the requirements of the Corporate Average Fuel Economy standards, which mandate carmakers achieve a standard of 52.5 miles per gallon in testing, equivalent to about 40 miles per gallon in on-road performance, by 2025. CFA's report singled out Mazda as setting an exemplary standard.
