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.

Peugeot will prove it doesn't offer cheater diesels

Our diesels are clean, really. That's the message from French automaker PSA/Peugeot-Citroen as it plans to go on the offensive in response to Volkswagen's diesel-emissions scandal. PSA will go out of its way to prove its diesels are as clean as advertised. The company is looking at disclosing "real-world" fuel-economy statistics as soon as next spring and will use an independent entity to vet the numbers, Automotive News Europe says, citing comments that PSA/Peugeot-Citroen financial chief Jean-Baptiste de Chatillon made to reporters this week. Such efforts may be vital, since roughly two-thirds of the vehicles Peugeot-Citroen sells in Europe are powered by a diesel engine. Last month, VW admitted that as many as 11 million of its diesel-powered vehicles were programmed with software designed to cheat emissions-testing systems. The news shook up the industry, especially companies that sell a good chunk of diesels. The EU itself may start instituting "real world" fuel-economy and emissions testing as soon as 2017. French regulators have said they may eliminate diesel-fuel subsidies that currently make diesel fuel cheaper to customers than gas. That adjustment may occur as soon as next year, since it's been pushed up in response to the VW scandal. Peugeot-Citron continues to reiterate that it has never installed software that was designed to cheat emissions-testing systems. Additionally, the automaker was more than a decade ahead of European Union mandates for engine components designed to cut soot emissions, so the company is hoping its track record makes a difference. It wants to be perfectly clear about that.

Volkswagen's 261-mpg hand-built XL1 headed for Geneva

After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.
As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.
XL1 power comes from a two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 146 mph.
