VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

Recharge Wrap-up: Tesla firmware update videos, Mercedes S500 Plug-In Hybrid

See the Tesla Model S with Firmware 6.0 in action in new videos from Teslarati. The large software update includes improved traffic-based navigation, a calendar function, updated power management, "Location-Based Smart Air Suspension" as well as other improvements. Drivers get more route options to save energy, and more control over how the car saves energy. The car can also remember ride height settings when driving in those same locations again. Additionally, you can start and drive the car without a key, just using the smartphone app. See how it all works in the videos below, the second of which focuses on pairing with the updated phone app. The California Public Utilities Commission (CPUC) has deemed ride-hailing app Uber's carpooling service illegal. The way the UberPool service is categorized by the CPUC, charging multiple riders separate fares for a single ride runs afoul of the law. The technical details are a bit convoluted, and what supporters could deem arbitrary, but Forbes delves into the details a bit further to try to make sense of California's intentions (even considering the possibility of other ride services, such as airport shuttle companies, fueling the fire). Lyft - which operates a similar service called LyftLine - and Sidecar have also received notices from the CPUC. Read more at Forbes. China's recent enthusiasm for electric vehicles could be largely attributed to a single person, Ma Kai. After the Politburo member was named vice premier, he encouraged maintaining and increasing EV subsidies when China sought to decrease them. He also seems ready to fight for more EV deregulation to encourage more clean vehicles. Read more about Ma Kai and what he's done for China's EV legislation at Automotive News. Mercedes-Benz begins deliveries of the S500 Plug-In Hybrid this month. The high-tech luxury PHEV features energy saving modes based on driver, route and traffic, and features a haptic accelerator that can signal when the driver should ease off to save power. It's powered by a biturbocharged V6 and 85-kW electric motor. Its 8.7-kWh battery offers about 20 miles of electric driving. The S500 plug-in starts at about $146,000.

2016 Formula 1 Chinese Grand Prix recap: another wild show on and off track

Normally we use this space to provide a lengthy recap of the weekend's Formula 1 race, but we're going to try something different since most folks reading this know what happened at the Shanghai International Circuit on Sunday. Instead, we'll alight on what we saw as the big issues in and around the race. Let us know what you think in Comments. Proper qualifying is back. Thank goodness. It only took a month of embarrassment to fix it. And so is passing! For the third race in a row, big performance improvements at the ten teams behind Mercedes-AMG Petronas and a wider tire selection at this race graced us with opening stints filled with dicing cars. Seeing the McLarens on screen doesn't make us cringe. Manor doesn't only make the global feed when it's being lapped. We've been complaining about parade races for so long that we forgot excitement was possible without rain or wholesale regulation changes. Yes, Mercedes is still the king of the jungle, but there are some other proper midfield beasts on the hunt, too. Malfunctions up and down the grid did help the show in Shanghai, like Lewis Hamilton suffering perpetual troubles, Nico Hulkenberg's runaway front wheel which red-flagged Q2, and Sebastian Vettel's and Kimi Raikkonen's flubbed hot laps in Q3 that let Daniel Ricciardo slip by into second on the grid. Come race day things went all Grand Theft Auto at Turn 1 on the opening lap, sending some of the best cars to the pits. Then came Ricciardo's puncture while leading, then came the Safety Car – all by Lap 5. Nico Rosberg got 38 seconds of airtime on the way to victory – at the start and the finish, and that happened to be his margin of victory, too – otherwise he was a ghost. Everyone else was struggling and juggling. Rosberg's win at the Bahrain Grand Prix put the German at five consecutive victories going back to last year's Mexican Grand Prix. The history books show that any driver who's won five straight contests has gone on to win the championship. With his triumph in China, the German has won the season's first three races, the history books again show that the other nine drivers who've pulled that off have gone on to win the championship. Rosberg, 36 points ahead of his teammate in the standings, is having none of it. He said of the other victors, "But they didn't have Lewis Hamilton as their team-mate." Perhaps Mercedes was right not to make an engine deal with Red Bull last season.
