Kimi Raikkonen fastest in first Belgian Grand Prix practice

SPA-FRANCORCHAMPS, Belgium — Ferrari's Kimi Raikkonen lapped fastest in first practice for the Belgian Grand Prix on Friday but Mercedes, and title contender Lewis Hamilton, still looked every bit the team to beat. A four-time winner at Spa, and with a contract extension for 2018 announced earlier in the week, Raikkonen lapped the longest track on the calendar with a best time of 1 minute 45.502 seconds. The 37-year-old Finn's time was set on the quickest ultra-soft tires, however, while Hamilton — preparing for his 200th race start — was second-fastest and only 0.053 slower on the soft compound. Hamilton was 0.092 faster than Ferrari's world championship leader Sebastian Vettel, with the German third on the timesheets and also setting his time on the quickest but least durable tire. Vettel leads Hamilton by 14 points with nine races remaining. Red Bull's Dutch teenager Max Verstappen, Belgian-born and attracting a huge traveling support of orange-capped fans, was fourth fastest with Australian team mate Daniel Ricciardo fifth. Hamilton's teammate Valtteri Bottas, who bumped into the tire barrier after going off across the gravel and damaged his front wing, was sixth fastest. The session was halted after 15 minutes when Brazilian Felipe Massa, who missed the previous race in Hungary after feeling dizzy in practice, crashed heavily into the tire barrier at turn seven out of Les Combes. He was taken to the medical center for checks, before returning to the pitlane, with his team facing a long job rebuilding the car. The session resumed after a 10 minute stoppage. Williams said the chassis would have to be changed and the team still hoped to get the car back out on track for some of the day's second session, even if that looked like being optimistic. Fernando Alonso suffered a lack of power in his McLaren, but still ended up 13th fastest. Belgian team mate Stoffel Vandoorne, who will start his home race last on Sunday thanks to a 35 place penalty due to a power unit change, was 10th.

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.

US buyers show little interest in big hybrids

The idea of producing large, luxury-vehicle hybrids is turning into a "what were they thinking?" exercise in futility, USA Today reports. General Motors is discontinuing hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon SUVs, while Mercedes-Benz and Toyota's Lexus division are doing the same with their S-Class hybrid and LS hybrid sedans, respectively. The culprit? Big price increases for fuel economy improvements that border on the unimpressive. Granted, the Escalade hybrid gets 31 percent better fuel economy than the standard version, but that still maps out to a combined fuel-efficiency rating of just 21 miles per gallon. That can be seen as a worthwhile increase, if it didn't cost over $8,000 extra. The 2014 Escalade Hybrid, for example, starts at $74,425 while the non-hybrid can be had for $66,295. Meanwhile, the Lexus full-size hybrid costs $6,000 more than the regular version but only gets 1-2 mpg better combined fuel economy. The result of all these high costs? Low sales. Through April, GM sold 82 of its hybrid SUVs and pickups, down from 541 a year earlier. And the LS hybrid sales were in single-digit territory for April. That isn't stopping Lexus from promoting its hybrids as the right solution (with the wrong facts), though. There are still automakers giving big hybrid vehicles a shot, though. Nissan's Infiniti division is selling a hybrid version of its QX60 and says an impressive 10 percent of QX60 buyers choose the hybrid, which costs just $3,000 more. Looks like money talks.
