Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

Next-gen Mazda6 reportedly getting RWD, straight-six it shares with Toyota

Last June, Japan's Best Car magazine laid out what we considered a whopper series of rumors about future Mazda developments. The mag said it had been speaking to a Toyota source on an unrelated matter, and found out that Mazda's work on a straight-six Skyactiv engine was predicated on that engine's use in Toyota Group vehicles, including Lexus models. Car and Driver has apparently consulted its own sources, and in a new report utters many of the same pronouncements as Best Car. The next-generation Mazda6, due around 2022, will molt out of its transverse engines on a front-driver platform, and be the first home for the longitudinally-mounted straight-six on the automaker's new rear-wheel drive "Large Architecture."  The gas-powered Skyactiv-X six-cylinder, a shade under 3 liters of displacement, will get help from a 48-volt hybrid system, and top output could hit 350 horsepower. A second straight-six will come in an oil-burning Skyactiv-D flavor, and PHEVs are certain to eventually factor into the equations. The sheetmetal around the bodywork will draw inspiration from the four-door Mazda Vision Coupe concept that debuted at the 2017 Tokyo Motor Show. Describing a scenario we can only cross our fingers for, C/D writes "there's a chance Mazda will mimic Lexus and put inline-six into both four- and two-door bodies," grabbing another unused concept as a design guide for the latter, the two-door RX Vision concept from the 2015 Tokyo Motor Show. C/D suspects the increasing cooperation between Mazda and Toyota will not only pay the bills for Mazda's sports sedan, but compel the Large Architecture to take a couple of side jobs in Toyota City. C/D writes, "Toyota may adopt the six-cylinder Skyactiv-X for the next-generation Lexus IS and RC." According to the recently leaked dealer report, the next-gen IS could be with us in 2021 as a 2022MY offering. Betting money seems to be on the sedan sticking with Toyota's TNGA platform and Lexus engines until a brand new model shows around 2026, though.

Mazda recalls 2019-2020 Mazda3 for errant activation of emergency braking system

The newly redesigned Mazda3 has been subject to numerous recalls since it went on sale for the 2019 model year. Today brings news of another such occurrence, as Mazda recalls 35,390 2019-2020 Mazda3s (sedans and hatchbacks). This recall is related to the automatic emergency braking system equipped to certain models. According to Mazda, affected vehicles may “unexpectedly stop while driving due to inadvertent activation of the Smart Braking System automatic emergency braking system.” The programming of the systemÂ’s software could cause the Mazda3 to “falsely detect an obstacle in front of the vehicle while driving.” In response to that detection, the software may automatically apply the brakes despite no collision being imminent. We donÂ’t have to explain how dangerous that could end up being for the driver and those around them. Your car slamming on the brakes for no reason could easily be the cause of an accident. As of now, Mazda says no injuries or deaths have been reported as a result of the defect. In case you havenÂ’t experienced the system in your Mazda3 yet, there is something to look out for. Mazda says a warning alarm will sound and a warning message will appear in the instrument cluster and head-up display when the car is about to perform an emergency stop. Mazda said that itÂ’s reported the defect to the NHTSA, but it hasnÂ’t been posted on the website yet. The fix is easy for some, but more difficult for others. Vehicles with early build dates will need the whole instrument cluster replaced or reprogrammed, as these cars have a different procedure for "temporary manual deactivation of the Smart Braking System." These early build cars will also receive a new owner's manual to reflect the revised procedure of temporary manual deactivation of the system. Later cars will only need the Smart Braking System software reprogrammed with an improved version. Mailings to owners for notification purposes should be completed on or before February 17 next year.
