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.

Race Recap: 2015 Canadian F1 Grand Prix is better behind the front

As of Saturday afternoon in Montreal, Canada, it was all about the number four. Lewis Hamilton put his Mercedes-AMG Petronas on pole position for the fourth time at the Circuit Gilles Villeneuve, and now his tally of pole positions matches his race number: 44. Nico Rosberg lines up beside him, which is the fourth time that particular one-two combo has occurred this season. Ferrari spent three engine development tokens to try and close the gap to Mercedes, Kimi Raikkonen making the most of it with third position on the gird. His teammate Sebastian Vettel got the worst of it, however, when the MGU-K unit failed during Q1, leaving him 160 horsepower down and out at the first hurdle. Valtteri Bottas put a revitalized Williams on the grid at fourth, ahead of a Lotus lockout of the third row with Romain Grosjean leading the way in fifth, Pastor Maldonado just beside. Nico Hulkenberg got the first Sahara Force India into seventh – the team is still waiting on the upgraded B car that should be available for Austria – ahead of Daniil Kvyat in the first Infiniti Red Bull Racing and a "pissed off" Daniel Ricciardo in the second Red Bull. Sergio Perez made it two Force Indias in the top ten, a welcome result from a team performing below expectations of late. When the lights went out, at the very front it was much ado about not that much at all. Hamilton got away clean and stabbed across the track to close the door for Rosberg, giving Raikkonen a chance to take the inside line into Turn 1 in an attempt to clear Rosberg for second place. That didn't happen, leaving the two Mercedes' to run in grid position for the entire race. It wasn't boring – Rosberg stayed close, rubber-banding the time gap to the leader from a little more than one second to just under four seconds, and Montreal is famous for race-rearranging safety cars and on-track incidents. But none of those occurred, so Hamilton crossed the line 2.285 seconds ahead of Rosberg after 70 laps to earn his fourth victory in Canada and the first-ever victory for the Brackley, UK-based Mercedes team. Valtteri Bottas drove his Williams to third position, the first podium place for the team this year and a welcome salve to heal the team's wounds from a poor showing in Monaco. That placing came courtesy of being in the right place at the right time, which was not far behind Raikkonen when the Ferrari driver spun at the hairpin on Lap 28 after his first pit stop.

Formula One speeds towards radical thousand-horsepower shakeup

The teams, the drivers, the fans, the circuits... few, if any, were satisfied with how Formula One has shaped up since the current regulations took hold last year. But that doesn't mean they aren't working on it. At a recent meeting of the F1 Strategy Group, the leading parties in the sport outlined a new framework that would radically shake up the cars themselves while keeping costs in check. And the biggest change could see the engines producing around 1,000 horsepower. Although a proposal put forth by Ferrari to ditch the current V6 hybrid engines in favor of new twin-turbocharged units was rejected by Honda and Mercedes, the members of the group approved in principal to increase the fuel flow in the existing engines to dramatically boost output. As it stands, the current 1.6-liter turbocharged V6 engines develop around 600 horsepower, with an additional 160 or so kicked in by the electric Energy Recovery System, for a combined output of about 760 hp. What's not clear at the moment is whether the increased fuel flow would necessitate either the return of mid-race refueling (currently banned) or the installation of larger fuel tanks. Red Bull and McLaren also submitted proposals to radically redesign the shape of the cars as well, however a more evolutionary approach was adopted instead. Though far from finalized, the new design would keep the same basic form of the current chassis, but with adjustments to make them more aesthetically pleasing while producing more downforce. Wider tires are also said to be part of the mix. With more power and more grip from the tires and aero, the resulting cars would most certainly end up going much faster than the current ones, which are already starting to nudge the lap records at some of the circuits, many of which were set during the V10 era. The F1 Strategy Group is made up of representatives of the FIA, Formula One Management and six leading teams. The next step will be for the teams' technical directors to iron out how to implement what their bosses have agreed to. If they settle the details fast enough, the revised regulations could be pushed through in time for next season.
