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.

Toyota Mirai hydrogen car on sale in Europe by end of summer

Want to see Toyota hydrogen fuel cell vehicles cruising down the Autobahn? It could happen as soon as September. Benz and Bimmer drivers, beware. The Japanese automaker, which started hometown sales of its hydrogen fuel-cell electric Mirai in December, will expand distribution of its first mass-produced fuel-cell car to Europe by September. The first three countries Toyota is targeting are the UK, Denmark and Germany, and the price will be 66,000 euros ($73,000). The caveat, of course, is that this is going to be a low-volume affair (a maximum of 100 cars per year for this year and next) and that the rest of the Continent won't get the Mirai until 2017. Toyota, which is showing off the Mirai at the Geneva Motor Show, will start California deliveries of the Mirai later this year, pricing it at $57,500 for those who want to buy and $499 a month for those who prefer to lease. Toyota also said in January that it would bump Mirai production to about 2,000 units in 2016, up from 700 this year. Toyota is spending about $168 million for that production increase, necessitated in part by the European plans. The Mirai delivers 153 horsepower and has goodies such as lane-departure alerts and collision-avoidance systems, along with the zero-emission hydrogen fuel cell powertrain, of course. Check out Toyota's press release below.

The Geneva motor show is its first public display in Europe. The Mirai2 signals the start of a new age of vehicles. Using hydrogen - an important future energy source - as fuel to generate electricity, the Mirai achieves superior environmental performance with the convenience and driving pleasure expected of any car. The Mirai uses the Toyota Fuel Cell System (TFCS), which features both fuel cell technology and hybrid technology, and includes Toyota's new proprietary FC Stack and high-pressure hydrogen tanks. The TFCS is more energy efficient than internal combustion engines and emits no CO2 or pollutants when driven. Drivers can also expect the same level of convenience as offered by gasoline engine vehicles, with a generous cruising range and a hydrogen refuelling time of about three minutes3.

Toyota GT86 convertible could debut in March

The dates are lining up, now we wait to see how the badges align. Just before the Toyota GT 86/Scion FR-S/Subaru BRZ line-up was introduced at the Tokyo Motor Show last year, there was a report that Subaru was considering a convertible while Toyota wouldn't even comment on it. That got swapped around when earlier this year the chief engineer on Toyota's side said a convertible was coming, and then a Scion FR-S droptop was confirmed for early 2014.
Autocar now reports that the Toyota GT 86 convertible will make its first appearance at the 2013 Geneva Motor Show in March. In a car whose specs like weight, packaging, horsepower and center of gravity were all tightly controlled to get the most from the least, the changes necessitated by chopping the roof could make this a very different car. It's said to employ a fabric roof to keep a "small" weight gain check, and the suspension will be softened to work more harmoniously with the decreased body stiffness. And somewhere in all that the back seat and trunk space will need to take a hit.
In other news, Autocar says the hi-po GT 86 with some kind of capacitor system instead of batteries is being worked on for 2015.
