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.

Volkswagen throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

Take a listen to the Volkswagen ID 3 and Koenigsegg Jesko

What could better demonstrate our diametric vehicular future than sound clips of the Volkswagen ID 3 and the Koenigsegg Jesko? Battery-electric vehicles don't make enough noise on their own, so VW partnered with composer Leslie Mandoki for the legally-mandated Acoustic Vehicle Alerting System (AVAS) that warns pedestrians and cyclists of the EV's presence. Mandoki — a German-Hungarian who once played drums in a Euro disco band called Dschinghis Khan — was asked to come up with a sound for the ID 3 that VW said "defines its identity," "radiates safety and the promise of effortless mobility," and that "must also impress with its unique character." The definition of the ID 3's single-motor, 201-horsepower character is this: Occupants and people around the hatch can hear the sound as the car accelerates to 18.6 mph, and when reversing. At higher speeds, the sound of wind resistance and tire noise takes over. As our library of AVAS tones grows, it's clear that EVs will provide a soundscape as varied as that of internal combustion engines. Here, for instance, is the industrial thrum used as the Karma Revero GT's pedestrian warning: And here is the sci-fi soaring from the BMW Vision M Next, as composed by Hans Zimmer: At the other end of the aural chamber, we have the Koenigsegg Jesko. In this case, the composer is a 5.0-liter twin-turbo V8 running on a bio-ethanol E85 blend that's almost suitable for IndyCar, powering the engine up to 1,600 horsepower. Output on pump gas will be 'only' 1,281 hp. The Swedish automaker released a clip of the exhaust note of a car in progress inside the Angelhom factory.

All these sounds have a place at the table, even if we'd prefer Karma booked some time with a producer and an Autotune session. To paraphrase Sesame Street, though, one of these sounds is definitely not like the other.
