Recharge Wrap-up: Innova EV Car Share, Mercedes to use CO2 A/C

Innova UEV will launch its carsharing program at the Association for the Advancement of Sustainability in Higher Education 2015 Conference & Expo. Called Innova EV Car Share, the program is designed for college campuses, and uses the Innova Dash neighborhood electric vehicle and solar charging stations. "The Innova UEV team is excited to introduce this innovative sustainability program to universities across the country as a way to reduce CO2 output as well as decrease congestion," says Innova UEV Founder and CEO Roman Kuropas. "Visionary schools that make this level of commitment to the environment are sure to add to their sustainability prestige as leaders in higher education."

ABB chargers will connect to the Microsoft Azure cloud, allowing for smarter charging as infrastructure expands. "Platform performance and stability are critical differentiators for the successful operation of a modern, data-dependent EV charging station," says ABB's Pekka Tiitinen. "By partnering with Microsoft, ABB will be able to offer best-in-class operations as well as innovative advanced services - what we call the Internet of Things, Services and People." Perhaps we'll hear more specific details following the platform's launch at eCarTec in Germany. Read more from Microsoft. Honda is testing solar-powered EV charging in the Marshall Islands. The AC charging stations, called the Honda Power Chargers, will help power a fleet of Fit EVs on the remote islands as part of a pilot test. The Marshall Islands must import most of their energy supplies, so solar-powered mobility would help provide some self-sufficiency and cost savings. Honda, the Marshall Islands government, and the Japanese Ministry of Economy, Trade and Industry will use the experiment to determine if it would be worthwhile to expand the solar-powered charging infrastructure.

The European offerings of the S-Class and E-Class will be the first to use a CO2-based air conditioning system. The use of CO2 requires a redesign of much of the system, as it requires a much higher pressure than other refrigerants. The automaker will use the HFO-1234yf refrigerant in its other vehicles.

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.

Brabus 850 6.0 Biturbo Coupe is an extroverted, 217-mph Mercedes S63 AMG

The Mercedes-Benz S-Class is a prime example of handsome, restrained design. It's classy but not shouty, stylish without trying too hard. Of course, Brabus can address that um, problem, for you, without much issue. Meet the Brabus 850 6.0 Biturbo Coupe, an extensively modified version of the S63 AMG Coupe. Larger intakes and lots of carbon fiber typify the front end, while the tail sports a new diffuser and rear spoiler, both of which are finished in carbon fiber. Meanwhile, Brabus is offering a variety of wheel designs, ranging in size from 18 to 22 inches, and with the customer's choice of Continental, Pirelli and Yokohama rubber. The most questionable changes, though, happen in the cabin, where black Mastik leather is finished with copper stitching and piping. Brabus then takes 219 different interior trim pieces and lines them in Shadow Gold paint, just like the Monoblock wheels featured on the vehicle above. Of course, Brabus does much, much more than just offer its own take on the normally conservative Mercedes aesthetics. There's a bit of tweaking to the powertrain. Despite the "6.0" in its name, the donor S63 AMG's 5.5-liter, biturbocharged V8 has been enlarged to just over 5.9 liters (5,912 cc, to be precise), thanks to a larger cylinder bore and a longer stroke, the latter of which comes from a Brabus-spec crankshaft. While Brabus may be exaggerating about the size of its new coupe's engine, the tuning firm is not overstating said powerplant's output. A stout 850 horsepower is teamed with an electronically limited 848 pound-feet of torque. There's more to this modded Mercedes than that, though, as Brabus claims the 5.9-liter is actually capable of turning out a silly 1,069 lb-ft, but that it needed to be limited "in the interest of the longevity of the entire powertrain." All this extra oomph comes from a pair of "special" Brabus turbochargers, as well as new exhaust manifolds and a stainless steel exhaust system. A new intake module also helps breathing, while the engine's ECU has been updated for extra performance. Aside from a new set of paddle shifters, the S63 AMG's seven-speed gearbox was left unaltered, as was the 4Matic all-wheel-drive system. Oh, and if you live in Europe and really want to scare yourself, Brabus will offer the same engine treatment to the rear-drive S63 AMG that we don't get Stateside.
