Mercedes driver Lewis Hamilton buys LaFerrari

Lewis Hamilton has driven some of the fastest cars ever devised, like the McLaren MP4-23 with which he won the 2008 Formula One World Championship, the Mercedes W05 with which he won the title last year, and the new W06 he drove to the checkered flag in the season opener earlier this month. But what does he drive in his spare time? According to the latest reports quoting his boss Toto Wolff, the reigning champ celebrated his win at the Australian Grand Prix by ordering a new LaFerrari. The seven-figure, 950-horsepower hybrid hypercar may be made by a rival manufacturer to the team for which he drives, but then his employers at Mercedes don't (for the time being at least) build anything that competes in the segment – unlike his former employers at McLaren that offer the similarly potent P1. Something tells us he won't be invited to drive it at Fiorano, though - which is something his rivals Fernando Alonso, Kimi Raikkonen and Sebastian Vettel have all had the chance to do. Hamilton has a long-established penchant for driving twelve-cylinder exotic supercars in his spare time. At his previous place of work, he was promised an exceedingly rare McLaren F1 LM – valued at some $4 million – but only if he won three world titles for the Woking-based team. He also owns a Pagani Zonda that was made specifically for him with a 760-horsepower engine (supplied, naturally, by Mercedes) and a six-speed manual – complete with a clutch pedal, which (apart from starting off the line) is something he doesn't usually get to operate during working hours.

Man makes record-setting drive across the US in 28 hours, 50 minutes

Records, as the say, are made to be broken. Whether that's cramming the most hot dogs down your gullet, running a faster mile, or yes, driving across the United States, odds are that there's someone out there wants to eat more, run faster or drive harder. Speaking of that last example, the record for driving from a set location on the east coast, in particular the Red Ball Garage in Manhattan to the Portofino Hotel in Redondo Beach, CA, has been one that has fascinated gearheads since a guy named Cannonball Baker made the trek from New York to LA in 53 hours, 30 minutes, in 1933.
The competition saw its glory days when Car and Driver's Brock Yates came up with the Cannonball Baker Sea-To-Shining Sea Memorial Trophy Dash (more affectionately known as the Cannonball Run), although the record was most recently set by Alex Roy and his 32-hour, seven-minute trek behind the wheel of a BMW M5 in 2006. Now, there's a new champion, who made the trip from east to west in a scarcely imaginable 28 hours and 50 minutes, behind the wheel of a 2004 Mercedes-Benz CL55 AMG. That's works out to an average speed of 98 miles per hour over the course of 2,813.7 miles.
His name is Ed Bolian, and Jalopnik has a writeup of the epic voyage that details everything from the history of the Cannonball Run to Bolian's preparation and trouble finding co-drivers, to the trip itself. It is well worth a read.

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.
