McLaren Racing will return to Mercedes F1 engines from 2021

SOCHI, Russia — McLaren will be reunited with Mercedes engines from the 2021 season as the former champions go back to using the German manufacturer's power units in their bid to return to the top. The Woking-based team are currently supplied by Renault, having joined forces with the French company last year. They will see out that deal, which runs until the end of 2020, before making the switch back to Mercedes as part of a long-term agreement until at least 2024. "We are delighted to welcome McLaren back to the Mercedes-Benz racing family with this new power unit supply agreement," said Mercedes' motorsports head Toto Wolff in a joint statement with McLaren issued at the Russian Grand Prix on Saturday. "We hope that this new long-term agreement marks another milestone for McLaren as they aim to take the fight to the sport's top teams, including our Mercedes works team." The McLaren-Mercedes partnership initially ran from 1995 to the end of 2014. It turned McLaren, enduring a slump after their heady days of dominance during the late 1980s and early 90s with Honda, into a force to be reckoned with once again. The combination won 78 races, a constructors' title and three drivers' titles with Mika Hakkinen (1998, 1999) and Lewis Hamilton who raced to his first Formula One title with the team in 2008. McLaren find themselves in a similar phase now, rebuilding after three dismal years with Honda, the Japanese manufacturer they rejoined forces with at the end of 2014 in a bid to recreate their dominance from 30 years ago. Fielding a fresh driver line up of British rookie Lando Norris and Spaniard Carlos Sainz, they have made big strides this year and are currently locked in a battle for fourth in the overall standings with Renault's works team. But they haven't won a race since the season-ending 2012 Brazilian Grand Prix, when they were still powered by Mercedes. "Renault has been instrumental to our Formula One recovery plan and a fantastic partner to McLaren Racing," said Zak Brown, chief executive of McLaren Racing. "This agreement is an important step in our long-term plan to return to success in Formula One." McLaren's new deal with the German manufacturer, whose power units have set the benchmark in Formula One's turbo-hybrid era, coincides with a planned rules overhaul aimed at leveling the playing field and creating better racing. The shake-up could be just what a team like McLaren need to make that final jump up to the top.

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.
