Volkswagen E-Co-Motion Concept brings electric mobility to the commercial set

Volkswagen sees a future where the bulk of the world's freight is moved into city centers by train, then offloaded onto a fleet of smaller, light-duty commercial vehicles for final delivery. Those vehicles could wind up looking something like the company's E-Co-Motion Concept that debuted at the 2013 Geneva Motor Show. The EV features a modular underfloor drive unit comprised of a battery, motor and gearbox that can be paired with any number of cab and body configurations to suit a buyer's needs, from a refrigerated box to a standard flat bed.
The E-Co-Motion Concept features a rear-mounted electric motor with 113 horsepower and 199 pound-feet of torque. A standard 20 kWh battery pack provides a driving range of up to 62 miles, while 30 kWh and 40 kWh packs could deliver 93 and 124 miles of travel, respectively.

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.

2013 Volkswagen Golf R Cabriolet

The Golf VI's Last Hurrah Is Pure Niche
This was in the heart of the ultra-chic Côte d'Azur during winter. The car to be tested was the not-for-North America 2013 Volkswagen Golf R Cabriolet. Prevailing weather conditions here this time of year are bizarrely pleasant, as though a dome of Swarovski crystal has been placed over the entire region to protect it from any real winter spoiling things. And the zippy Golf R Cabriolet is a sports car designed precisely for this area's preciously narrow winding streets, as well as for the lofty budgets of its property owners.
So then why was it snowing like we were in northern Michigan? The weather front hit from the north like a swift kick to the Jordaches. The roof was open on this Candy White Golf R Cabrio and I, as is my wont, was determined through thick or thin to keep it retracted. It had been raining and sometimes sleeting like the End of Days, but I kept the lid cracked because the 261-horsepower cabrio - the most powerful convertible ever built by Volkswagen - was snipping along nicely as the bad weather blew over my head and wetted only the rear headrests.
