2019 Mazda3 fuel economy announced for AWD, hatchback models

Although Mazda engineers gave us fuel economy numbers for one configuration of 2019 Mazda3 at the car's Los Angeles debut, there were still a few versions left out. Now Mazda has released the data for every body style, drivetrain and transmission configuration. That includes the all-new all-wheel-drive iteration, which we will have a full review of this week. Discerning these numbers is a tad tricky since there are three powertrain combinations for each 2019 Mazda3 bodystyle, and they all get slightly different fuel economy. We've listed the different combinations in a chart below: There are a few key takeaways, the first being that the sedan is always the most efficient version of the Mazda3, likely because of better aerodynamics compared to the hatchback. Second, all-wheel drive will cost you fuel economy due to the extra weight of the axles and differential, and the added drag on the engine. Third, the most efficient versions of each body have the same fuel economy numbers as the outgoing Mazda3. The manual transmission-equipped Mazda3 has actually improved fuel economy over the old version by 2 mpg on the highway, and 1 in combined driving. Also worth noting is that only one trim level of the sedan is available with cylinder deactivation and front-wheel drive, and that's the top-level Premium trim. Opting for all-wheel drive on any trim or body style will come with an engine with cylinder deactivation. The hatchback is also the only Mazda3 available with a manual transmission, and it's only offered on the front-drive version.

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:

Mazda previews new CX-9 ahead of LA debut

Mazda will unveil its new CX-9 crossover at the upcoming Los Angeles Auto Show. The teaser rendering above gives us an idea of what to expect. The CX-9 was launched nine years ago. And though it's undergone a series of updates along the way, it's due for replacement. Fortunately that's just what Mazda has in store. We saw that much ourselves in spy photos and videos of the upcoming new model undergoing testing, and the company whet our appetites with the reveal of the Koeru concept at the Frankfurt Motor Show just a couple of months ago. Judging by the rendering above, it would appear that the new CX-9 will draw heavily from that design study in its production form. Naturally some details will be changed along the road from show stand to showroom, including the usual suspects like the wheel size and wing mirrors. Most notable, however, is that while the Koeru concept incorporated five seats, the CX-9 is a seven-seater – and the new model is confirmed to keep that three-row setup. Beyond that, the new CX-9 is set to apply the latest evolution of the company's Kodo design language – as seen on the aforementioned Koeru and sleek RX-Vision concepts – to a larger form. It also promises to feature Mazda's latest Skyactiv technologies to keep it up with the times. For more than that, however, we'll have to wait – but not too long, as the vehicle is set to debut mere weeks from now at the LA show. Mazda to Unveil All-New CX-9 Three-Row Midsize Crossover SUV at Los Angeles Auto Show HIROSHIMA, Japan, Nov. 4, 2015 /PRNewswire/ -- Mazda Motor Corporation announced today it will premiere the all-new Mazda CX-9 three-row midsize crossover SUV at the 2015 Los Angeles Auto Show, which runs from November 20 to 29. Fully incorporating the latest SKYACTIV technologies and KODO—Soul of Motion design, the all-new CX-9 is a high-end model of Mazda's new-generation lineup. The all-new CX-9 builds on the feeling of life imbued by KODO and moves toward a more premium design execution that befits a three-row midsize crossover SUV.
