Bentley considering diesel engine for new SUV

Turns out, in case you didn't know, the rich are just like regular people. They too are concerned about the environment, even when tooling around town in their super-luxurious Bentleys. So the automaker is weighing the idea of offering a diesel engine in its SUV offering, which could help satisfy customers' demands for more fuel-efficient engines.
Chairman and CEO Wolfgang Schreiber told Autoblog in a roundtable interview at the Geneva Auto Show that the automaker is researching whether or not a diesel engine makes sense for the brand. Bentley, owned by the Volkswagen Group, could in theory use a diesel engine from anywhere in the Volkswagen Group family. We at Autoblog have hopes they'll revive the V10 TDI used in the VW Touareg until 2010, but ever-stricter emissions laws would likely make that problematic.
But rich people aren't so much like us that they'll be worried about petty things like pricing. Schreiber admitted the diesel engine could be a $15,000 option, which he said customers would probably find "acceptable." Given that the cheapest Bentley today starts at $177,000, typical customers probably won't be diddling around worrying about an extra 15 grand.

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.

VW Golf GTI wrung out by Chris Harris

Enthusiasts like nothing more than to crucify modern interpretations of their favorite performance models for failing to live up to some imagined ethos. Even the Volkswagen GTI has suffered its fair share of slings and arrows for growing in size and curb weight. Chris Harris recently spent some time with the all-new MK VII GTI to find out if growing up means giving up on what makes the machine so special.
Judging by his comments, Harris certainly doesn't think so. Yes, the new GTI is considerably more comfortable than its predecessors, but that's hardly a bad thing. The multitude of driving modes actually seem to add depth to the car rather than simply try to force one tool to do many jobs, and Harris even finds the machine's electronic power steering tolerable. As a result, Harris goes so far as to call the Volkswagen GTI "one of the best cars to actually own." How's that for high praise? You can watch the video for yourself by scrolling below.
