VW invests in QuantumScape for potentially fireproof, long-range EV batteries

VW might be getting ready to push its plug-in technology in a big way thanks to an investment in the battery startup QuantumScape. Key point: the solid-state battery is said to be fireproof and will offer tremendous range advantages. Details are not abundant yet, but according to Bloomberg, VW of America bought a five-percent stake in QuantumScape (and has an option to raise its holding). The tech could "more than triple" the EV range of VW, Porsche and Audi plug-in vehicles as soon as the middle of 2015, according to unnamed sources that Bloomberg talked to. Former Stanford University researchers started QuantumScape in 2010. The bare-bones QuantumScape website (there's nothing there other than some contact information) doesn't offer many hints about what's happening at the company, but GigaOM's Katie Fehrenbacher notes that QuantumScape is licensing tech from the "All Electron Battery" project at Stanford a few years ago. It certainly sounds amazing: [It's] a completely new class of electrical energy storage devices for electric vehicles that has the potential to provide ultra-high energy and power densities, while enabling extremely high cycle life. The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. ... If successful, this project will develop a completely new paradigm in energy storage for electrified vehicles that could revolutionize the electric vehicle industry.

Editors' Picks March 2022 | Acura RDX, VW GLI and a Rolls-Royce

This month's Editors' Picks offer a little something at every budget. We call out a performance car as cheap as the Volkswagen GLI, but the Rolls-Royce Ghost also manages to make its way on to the list. Of course, very few folks can afford a Ghost, but that doesn't change the fact that it's an engineering master class. In addition to these options, we also dive into the compact luxury SUV market, one that is bursting with choices. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in March that earned an EditorsÂ’ Pick. 2022 Acura RDX Quick take: The RDX ticks a lot of boxes for a great price. It drives better than expected, offers excellent tech, has plenty of room and even looks the part. Score: 7.0 What it competes with: Mercedes-Benz GLC-Class, BMW X3, Volvo XC60, Audi Q5, Lexus NX, Infiniti QX50, Alfa Romeo Stelvio, Genesis GV70, Porsche Macan, Jaguar F-Pace, Lincoln Corsair Pros: Value, driving dynamics, space Cons: Infotainment is polarizing, midgrade interior From the editors Road Test Editor Zac Palmer — "The RDX is a bit of a sleeper in this segment. It drives far better than many of its competitors, and it doesn't let you down in any particular area. If you were thinking of buying an entry-level option from one of the Germans, make sure you take the RDX into account, because you'll likely end up with more tech and features for an even lower price. News Editor Joel Stocksdale — "The Acura RDX is an impressive value in the small luxury SUV segment. It starts in the low $40,000 price range, and provides loads of standard convenience and safety features. Everything is packaged in a sharp and surprisingly spacious package, too. It's also nimble and has a punchy engine that makes it fun to drive. You may find some competitors that surpass it in some areas, but the Acura offers about the most for the money of anything in the segment." In-depth analysis: 2022 Acura RDX Review | Value-packed and surprisingly sporty   2022 Volkswagen Jetta GLI Quick take: The GLI offers excellent driving dynamics and great styling for someone who doesn't want a hatchback. It's pricey, but it's worth it.

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.
