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?

Stock Miata beats bunch of high-powered cars in wet 1/4-mile drag race

When is a stock, 167-horsepower Mazda MX-5 Miata quicker than a Chevrolet Corvette, Ford Mustang, Lamborghini Gallardo, Lotus Elise and a Porsche 911? When it's raining. Sort of.
Mazda Canada arranged a unique drag race to show off the fact that the Miata's optional power retractable folding hardtop can go from top-down to top-up in just 12 seconds flat. In this video, all six cars line up for a drag race, and it starts to rain (well, sort of - but you'll have to watch the video all the way to the end to see what we mean). The green flag is waved, and the timer starts as soon as the convertibles begin to put their tops up. But because the Miata's roof mechanism gets the car's roof back up a full 5.1 seconds quicker than the second-place car, the Mazda gets a serious advantage off the line for the actual drag race.
It's a fun video. And while we've spoiled the results (come on, the video was uploaded by Mazda, you knew the Miata was going to win), be sure to see how it all unfolds, below.

2016 Mazda CX-5 recalled to address failing DRLs

Mazda announced Tuesday that it will recall more than 35,000 examples of the 2016 CX-5 crossover to address an issue that may lead to deterioration or failure of its LED daytime running lights.  In affected models, the gasket used to seal the wiring harness to the LED module was not manufactured to Mazda's specification. As it degrades over time, it can release sulfur, which in turn can potentially corrode the LED control circuit, causing the LEDs themselves to flicker, illuminate poorly or even fail outright.  Per Mazda, there is no alert for this condition, so drivers can potentially lose daytime running light function without realizing it, leaving them tougher to spot in poor light.  The campaign will cover 36,761 CX-5s sold in the U.S. and U.S. territories. Mazda says no accidents or injuries related to the issue have so far been reported.  This new campaign has not yet been published in the National Highway Transportation Safety Administration (NHTSA) recall database, and Mazda's statement did not include details of the proper remedy for the issue or when customers can expect to be contacted to arrange for service.  We expect that all 2016 CX-5s with LED DRLs will receive new harness gaskets and that those showing signs of LED module corrosion will have those replaced as well.  The 2016 CX-5 has been the subject of four other recall campaigns — including one for an improperly torqued steering knuckle bolt and another for a defective fuel filler pipe — but this is the first  new campaign for that model year since 2016.  Related Video: This content is hosted by a third party.
