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.

Get ready to Camino-ize your fourth-generation VW Jetta with this kit

Inexpensive, small pickup trucks used to be everywhere in the US, whether they were from Japanese brands like Datsun or Toyota, the truly weird Subaru Brat or even from Europe with the Volkswagen Caddy based on the Golf. These days that market has completely disappeared, but if you're willing to pick up some tools to build your own, there's a company out there bringing the Caddy back as a kit for the Jetta.
Mark Smith knows a thing about building a vehicle at home. He has over two decades in the DIY-car business as a co-founder of Local Motors and the company that became Factory Five Racing. His latest venture is Smyth Performance and already offers a mid-engine, VW-based kit called the G3F. His new product, though, started as a fluke. "I just wanted a shop truck," said Smith to Autoblog. He already had a Ford F-450 but found that he was driving around with the bed empty most of the time. The result was a pickup truck based on the fourth-generation Jetta that he dubbed the Ute.
The kit retails for $3,500 and ships in three, big boxes, and it's designed to be built and painted in a weekend. Buyers get fiberglass exterior panels, a fiberglass rear window surround, sliding rear window, an aluminum reinforced bed with a tubular steel subframe, taillights, a fully functional steel tailgate, and other parts. In the end, you get a vehicle with a six-foot bed and a payload of around 700-750 pounds. The Ute maintains all of the factory suspension, fuel tank and emissions equipment and requires just a few cuts in the body to complete. "We did a modern Caddy," admits Smith.

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.
