2019 Mazda 3 recalled because the wheels could fall off while driving

Here’s a recall we had to read twice before believing. Mazda is bringing in 25,003 Mazda 3s that just rolled off the assembly line, because the wheels may fall off while driving. All the Mazda 3s are 2019 model year cars, so itÂ’s only the totally new generation Mazda 3 under the gun here. Thankfully, Mazda says there are no cases of this occurring to owners, and therefore no injuries or deaths related to the issue. As for the cause of the wheel detachment? Mazda put out a statement explaining the issue at hand.  “A manufacturing process error may result in a gap between the wheel hub bolt and hub flange during assembly. This gap causes loosening of the lug nuts though they were initially tightened to the correct specification at the plant. A rattling noise occurs prior to a wheel detachment from the vehicle,” Mazda says. ItÂ’s heartening to see Mazda did in fact tighten the lugs at the factory, but still extremely troubling to see that they can loosen all on their own. Our advice? Walk on out to your shiny, new Mazda 3 and torque those lugs to spec. If you donÂ’t have a torque wrench, then just use the wrench that came with the car to make sure theyÂ’re not loose. Those that have a new Mazda 3 should be on the lookout for a recall notice in the mail. YouÂ’ll then be able to take the car to the dealer for Mazda to fix the problem. Until then, just keep an eye on your lugs. A wheel flying off while driving at speed is always a recipe for disaster, and we sure do enjoy driving the new Mazda 3 at speed.

2016 Mazda MX-5 Miata will rock 2.0L SkyActiv engine in US, 1.5L elsewhere

Let the speculation finally end - we know what will power the next-generation 2016 Mazda MX-5 Miata, and it's not turbocharged. The US model will get a SkyActiv 2.0-liter engine and six-speed manual, while models in the rest of the world have a 1.5-liter engine, confirming earlier rumors.
Unfortunately, Mazda isn't letting loose how much power either of these mills make just yet. For sake of comparison, the current SkyActiv 2.0 in the Mazda3 produces 155 horsepower and 150 pound-feet of torque, and the 1.5-liter in the UK (and elsewhere) has about 99 hp and 110 lb-ft of twist. However, the current Miata produces 167 hp and 140 lb-ft.
But fret not droptop fans. The company's brochure from the 2014 Paris Motor Show confirms, "all available drivetrains have been specially tuned for the all-new MX-5," which at least hints at the possibility of more performance. Also, even if the numbers remain untouched, the new Miata should feel even more sporting on the open road. That's because Mazda says the new model weighs in the neighborhood of 2,200 pounds; with that in mind, the 2016 car would boast around 14.19 pounds per horsepower versus 14.85 lb/hp in the present MX-5. Progress!

Mazda is developing gas and diesel inline-six engines

Once the favored engine configuration for luxury and high-performance cars, the inline-six suffered a bit when the transverse (east-west) engine configuration became popular during the shift to front-wheel drive cars. The packaging benefits are obvious – no driveshaft or transmission intruding on passenger space or rear differential on cargo volume, plus turning the engine 90 degrees meant the front of the car could be shorter. But the inline-six is slowly, slowly crawling out of near-obsolescence, notably in BMW, Jaguar-Land Rover and Mercedes-Benz products. Add Mazda to that mix: An investor report first spotted by Jalopnik and confirmed by Mazda reveals that the company is developing a Skyactiv-X and Skyactiv-D inline-six that will be installed longitudinally (north-south) in a new "Large Architecture" platform. Before reading any further, let's catch up on the Skyactiv-X and -D technologies. The former basically burns gasoline like diesel, providing some benefits and advantages of both types of combustion - here's an explainer on how that all works. We drove a prototype 2.0-liter Skyactiv-X 4-cylinder engine in a Mazda3 mule, too. And the Skyactiv-D series of engines is a comparatively typical turbodiesel. Mazda has a 2.2-liter turbodiesel inline-4 that has had a long and convoluted development and certification process, but is finally showing up in the 2019 CX-5. Since Mazda has implemented these technologies in existing four-cylinder engines, we would assume that the new Skyactiv engines will be "modular" – that is to say, they'll essentially be the existing engines with two extra cylinders, rather than an entirely new design. Jaguar-Land Rover is doing a similar thing with its Ingenium engine family. Assuming the Mazda engines will be modular would mean they'll be roughly 3.0-liter units, which is a common displacement for modern inline-sixes. And as we mentioned eariler, they'll be arranged longitudinally, unlike any other Mazda save the MX-5 Miata (and the long-departed rotaries), in a new vehicle architecture. As part of a medium-term plan over the next six years, Mazda will develop some unspecified vehicles on what it calls the "Large Architecture". These vehicles will have 48V mild hybrid and PHEV capabilities, and be able to use a version of Mazda's i-Activ AWD system. Why do this at all?
