Volkswagen formally introduces super-efficient XL1

Lightweight and low drag are hallmarks of great sportscar design. But when paired with a super-efficient, hybrid powertrain, you have the Volkswagen's XL1 that has been formally introduced in Geneva today.
When the 1,700-lb, carbon-fiber-bodied two-seater hits the road, its claimed 261 miles per gallon will make it the world's most-fuel-efficient production car. Though "production car" might be a stretch since VW said in a February press release that the XL1 would be built using "handcrafting-like production methods." We translate that to mean you won't be seeing many of these cars on the road. Though no one at VW has mentioned pricing yet, early rumors suggested a six-figure price tag.
That's supercar budget for a vehicle that has a 47-horsepower, two-cylinder diesel engine and a 27hp electric motor. With numbers like that, owners can expect 0-62 mph times of 12.7 seconds and top speed near 100 mph.

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.

2014 VW Golf brings storied hatchback's seventh generation to US

The seventh-generation Volkswagen Golf in US-specification officially debuts at the 2013 New York Auto Show. The new model is the first VW in the States to ride on the company's MQB architecture, and as such, it makes use of plenty of high-strength and ultra-high-strength steel to keep weight down. All told, the new shell is 51 pounds lighter than the outgoing generation, despite the fact that the finished car is a full 2.2 inches longer and .5 inches wider than the 2013 model.
Buyers can expect to find a base model powered by a 1.8-liter turbocharged four-cylinder engine (blue car above) with 170 horsepower and 184 pound-feet of torque. That means the powerplant delivers the same horsepower as the old naturally aspirated 2.5-liter four-cylinder while weighing less and producing seven extra pound-feet of torque. TDI (silver car above) buyers, meanwhile, will enjoy a new 2.0-liter turbo diesel four-cylinder mill. VW says the engine yields 10 more horsepower than the old lump, which means the Golf TDI now boasts 150 hp and 236 lb-ft of torque.
GTI (red car above) buyers will now get their hands on a revised 2.0-liter turbocharged four-cylinder with approximately 210 hp and 258 lb-ft of torque - Volkswagen hasn't finalized power numbers for that machine. We're happy to see that the GTI still features its trademark plaid seats. Volkswagen says the new Golf and GTI will go on sale as a 2015 model, but doesn't say when the car will actually hit dealerships.
