The VW emissions carnage assessment with an upside

Bombs cause destruction. Even if they're intelligently guided and pinpoint, there's always collateral damage. The strange Volkswagen brew, which is still spontaneously combusting in plain sight, will result in aftershocks for years. And the professional end of the corporation's top leadership will not be the only casualties. Blows are striking shareholder confidence, the residual value of the cars involved, consumer confidence, and the German economy itself. A hard rain's going to fall elsewhere, too. Here are just four damage assessment areas. The High-Compression Past and Low-Compassion Future of Diesels Despite European and especially German manufacturers' high belief that diesel engines were a way to light-duty automotive salvation, VW's scandal started the last nail in the fuel's coffin. Regulations both in the U.S. and in Europe for particulates and nitrogen oxide (NOx) are getting much harder to meet, and this is at the very core of VW's deception. Even with the high-cost exhaust after-treatment systems, sky-high fuel pressure, and sophisticated electronics, the inescapable NOx realities won't be washable by technology in an affordable way. German engineering pride will have to work a real miracle to meet these looming regs and the stain of VW's scandal did the whole diesel movement no favors. Perhaps not so ironically, the E.U. adopted more stringent emission standards this year, which closely mimic the U.S. Tier 2, Bin 5 figures phased in for 2008. Indeed, when VW announced it was able to meet the stringent US NOx emissions standards in 2009 for its diesel engines without urea injection as an exhaust after-treatment, it was a particularly high point of engineering pride for the company. No other manufacturer had figured out how to do so. One Honda official at the time remarked that they had simply no idea how VW was achieving this feat and Honda couldn't come close. Well, neither could VW. On a macro scale, European cities are also starting to face government fines for air quality violations. This is forcing those cities to find various ways to cut smog-related causes like tailpipe emissions. In fact, Paris has gone to the length of restricting car use on a sliding scale when smog persists, while electric cars are free to roam. France's longer and larger plan is banning diesel fuel for light-duty transportation entirely. But why was there a frothy focus by the European manufacturers on diesels in the first place?

VW Sport Coupe Concept GTE 'marks beginning of a new design era' [w/video]

You didn't think that Volkswagen was going to come to Geneva armed only with a bunch of European-market minivans and wagons, did you? Of course not. Last week VW gave us our first glimpse at a new show car for the Swiss auto expo, and here it is in full: the Volkswagen Sport Coupe Concept GTE. Set to be unveiled at the Geneva Motor Show this week, the Sport Coupe is envisioned as a successor to the current CC, but beyond previewing a specific model, this concept showcases a new design language that's set to characterize all new VWs to come. And judging by how good it looks from the images in the slideshow above, that could prove to be a very good thing indeed. The concept strikes us as the sleekest iteration yet of the company's flexible MQB architecture that already underpins vehicles as small as the Golf and as large as the new Skoda Superb. It's larger than the current CC in every dimension but height, and pushes the wheels further out on a longer wheelbase. And with a liftgate at the back instead of a trunk, it strikes a form more similar to the Audi A7 than the Passat-based CC. As with recent past concepts, VW has taken the opportunity to showcase its hybrid powertrain technologies, fitting the Sport Coupe with a plug-in hybrid system that couples a 3.0-liter turbocharged V6 to a pair of electric motors and a six-speed dual-clutch transmission. The internal combustion engine drives 295 horsepower and 369 pound-feet of torque to the front wheels, while an electric motor integrated into the gearbox contributes another 54 hp and a second one kicks in 114 hp at the rear. Juiced by a lithium-ion battery housed in the center tunnel and offering all-wheel traction, the combined output of 374 hp is said to be capable of propelling the concept to 62 miles per hour in five seconds flat and on to a top speed of 155 mph. It can travel for 32 miles on electric power alone and on to an overall range of 745 miles, netting the equivalent of 118 miles per gallon on the European cycle. Inside, the four-seat cabin is laden with digital displays: there's a 12.3-inch unit – dominated by the speedo and power meter – in place of a conventional instrument cluster. The center stack incorporates a 10.1-inch infotainment display, and the rear-seat passengers have access to another 12.3-inch display at the back of the center console and another pair of 10.1-inch displays in the seatbacks.

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.
