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.

FIA introduces 'Hypercar Concept' for World Endurance Championship

One of the most common jabs at hypercars is the question, "Where can you drive them to their potential?" Imagine the answer being: to the checkered flag in the 24 Hours of Le Mans. We're not there yet, but the FIA World Motor Sport Council took a step closer to the possibility during its second annual meeting in Manila, the Philippines. One of three initiatives the WSMC announced for the 2020 World Endurance Championship was "Freedom of design for brands based on a 'Hypercar' concept." This "Hypercar concept" would replace LMP1 as the premier class in the WEC. The dream, of course, would be seeing racing versions of the AMG Project One, Aston Martin Valkyrie AMR Pro, Bugatti Chiron, Koenigsegg Regera, McLaren Senna GTR, Pagani Huara BC, and the rest of the gang trading paint and carbon fiber through Dunlop in a heinously expensive version of "Buy on Sunday, sell on Monday." The reality is that we don't have all the details yet on the set of regulations called "GTP," but the FIA wants race cars more closely tied to road cars, albeit with the performance level of today's LMP1 cars. Exterior design freedom would shelter internals designed to reduce costs, the FIA planning to mandate less complex hybrid systems and allow the purchase of spec systems. One of the FIA's primary goals is lowering LMP1 budgets to a quarter of their present levels. Audi and Porsche budgets exceeded $200 million, while Toyota - the only factory LMP1 entry this year and next - is assumed to have a budget hovering around $100 million. Reports indicated that Aston Martin, Ferrari, Ford, McLaren, and Toyota sat in on the development of the proposed class. If the FIA can get costs down to around $25 million, that would compare running a top IndyCar team and have to be hugely appealing to the assembled carmakers. The initiative represents another cycle of the roughly once-a-decade reboot of sports car racing to counter power or cost concerns. The FIA shut down Group 5 Special Production Sports Car class in 1982 to halt worrying power hikes, and introduced Group C. In 1993, Group C came to an ignoble end over costs; manufacturers were spending $15 million on a season, back when that was real money and not one-fifth of a Ferrari 250 GTO. Then came the BPR Global GT Series that morphed into the FIA GT Championship, which would see the last not-really-a-road car take overall Le Mans victory in 1998, the Porsche 911 GT1. That era would be most aligned with a future hypercar class.
