Production Mazda Vision Coupe concept, GRMN Supra, new BRZ/86 coming

After writing about what's in store for the next-generation Subaru WRX, Japan's Best Car magazine is back with more spy work on what's ahead for the coming Mazda sedan, fighting-spec GRMN Toyota Supra, and next-generation Subaru BRZ/Toyota 86. All three are supposedly headed for previews at this year's Tokyo Motor Show before rolling out in 2021 and 2022. Mazda showed the Vision Coupe concept at the 2017 Tokyo show, then sneaked a mention of a rear- and all-wheel drive "Large Architecture" and two inline-six engines into a 2019 investor's report. Best Car says that concept's production version will house a 3.0-liter Skyactiv-X SPCCI inline-six with "M-Hybrid" 48-volt assistance. Output figures remain a mystery, but the mag says engineers are aiming for 345 horsepower. The real deal isn't slated for dealers until 2022, bringing what Mazda bills as a "BMW, Audi quality car at the price of Volkswagen." A further treat: Best Car says the Hiroshima automaker is laying out a two-door version on the same platform. Not even a month after 2020 Toyota Supra chief engineer Tetsuya Tada told us, "With a sports car, the promise is to offer more performance with each additional version," this report says the full-fat GRMN Supra will raise the stakes. Expected in the latter stages of 2021, the current 335-hp Supra will get an "output eventually close to 400 ps" (about 394 horsepower) from its BMW-source 3.0-liter straight-six. Along with that will come a lighter, stiffer body, and a sportier suspension tune to manage and make the most of the 60-horse increase. Best Car says the next-generation Toyota 86 / Subaru BRZ will move to a new platform, without specifying whether it would be Toyota's TNGA platform suggested by a report in April — not that there are many other options. Neither the footprint nor the body dimensions are predicted to change, and transmissions will continue to include a six-speed manual and a six-speed automatic. The new platform will hold a new engine, although it won't be the revelation many fans want. The magazine says the Subaru 2.0-liter FA20 will retire, making way for the Subaru 2.4-liter FA24. The FA24 is the same engine in the Subaru Ascent crossover, where it produces 260 hp and 277 lb-ft. There'll be no such fireworks for the sporty twins due in the first half of 2021, output reported to be "improved to 220 ps," or 217 hp — a 12-hp bump over the current figure.

Toyota Yaris iA, Mazda CX-3 sales show crossover formula isn't an automatic win

While 2017 was another watershed year for crossovers, in one interesting case, a crossover had its lunch eaten by its sedan counterpart. In the past year, Toyota sold nearly 36,000 Yaris iAs, a sedan that is identical to the foreign-market Mazda2 in everything but Toyota's ugly front bumper. In the same time frame, Mazda sold just over 16,000 CX-3s, a subcompact crossover based on the Mazda2. Not only that, but the Yaris iA saw an increase of around 8,000 units over 2016, and the CX-3 sold about 2,000 fewer units than in 2016. View 29 Photos There are a few reasons this is surprising. First of course is that the crossover market is surface-of-the-sun hot right now, so much so that primarily crossover-building brand Subaru saw its best sales year ever last year. Even Mazda's other crossovers, the CX-5 and CX-9 saw better sales in 2017 than in 2016. But on paper, the CX-3 has a number of advantages compared to the Yaris iA. The CX-3 has a larger 2.0-liter four-cylinder that makes about 40 more horsepower than the 1.5-liter engine in the Toyota. Also, while the cargo area behind the rear seats in the CX-3 is about one cubic foot smaller than the iA, it has the added flexibility of being a hatchback, and thus having more capability when it comes to large, bulky items. And of course, the CX-3 is quite a shapely machine compared with the awkward, angry-looking iA. That's not to say the iA doesn't have any of its own advantages. It gets 3 more mpg in the city and 6 more on the highway than the CX-3. It also costs roughly $3,000 to $4,000 less than a CX-3 and can be found at more dealers than the Mazda. But it's still surprising that a car, especially a sedan, can outsell a mechanically very similar crossover. Apparently the formula of adding more ground clearance and plastic fenders isn't foolproof. Then again, maybe it's not such a big deal to Mazda, since the CX-3's total sales were just over a tenth that of the Mazda CX-5. Related Video:

How to fix a $4,000 hybrid battery problem with vinegar and baking soda

This is one of those 'Don't try this at home if you don't know what you're doing' DIY tales. Two weeks after imgur user "scoodidabop" bought a used Toyota Camry Hybrid with no warranty, he got the Christmas Tree dash display with warnings like "Check VSC System," "Check Hybrid System," and the Check Engine light. After some Internet sleuthing he figured it could be a faulty brake actuator, assuming the hybrid system warning was a false alarm. But it wasn't the actuator, it was the battery, a Toyota dealer telling him that his battery had "gone bad," and he'd need $4,457 to replace it. Then he had a brainstorm: it could be one of the cells that's gone bad, not the whole battery. Scoodidabop has some experience as an electrician, so he figured he could test it and replace any bad cells for about $45 apiece. He removed the battery unit from the trunk and over the course of two hours tested all 68 cells four times. He found nothing wrong. So he devised another type of test and checked every cell again. He couldn't find a problem with any of them. Turns out the problem wasn't in the cells, but with the dirty and corroded copper connectors at the ends of the high-voltage cables. He pulled the 34 connectors and their steel nuts, soaked them in vinegar, gave them a light steel wool scrub, soaked them in baking soda and water to counteract the vinegar, applied an anticorrosive and reinstalled them. That took an hour. When he replaced the battery, the warning lights had all gone out and the battery worked perfectly. Skill level: experience. Cost: less than $10. Perhaps it's time for hybrids to be able to test their own cells individually. Dealers, too.
