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.

Editors’ Picks April 2023 | New X1, a Bentley and some luxury EVs

This month of Editors' Picks features a smattering of luxury vehicles in both sedan and SUV body styles. The new BMW i7 was a big surprise, and the Mercedes-Benz EQE is a lovely enough electric sedan to get our recommendation, too. We've given every other Bentley model an Editors' Pick before, and the Bentayga follows suit. Lastly, BMW nabs a second in April with the newly redesigned X1 subcompact crossover. 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 an EditorsÂ’ Pick designation. 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 January that earned an EditorsÂ’ Pick.   2023 Mercedes-Benz EQE 2023 Mercedes-AMG EQE View 38 Photos Quick take: The EQE offers all the niceties of a traditional E-Class in an electric form. Its design is simplistic and bland to a fault, but everything else about it is executed well. Score: 7.5 What it competes with: Porsche Taycan, Audi E-Tron GT, Tesla Model S, BMW i4 Pros: Gorgeous interior, big backseat, advanced tech, excellent driving AMG variant Cons: Bland design, average range/charging speed, questionable value From the editors: Road Test Editor Zac Palmer — "I drove the AMG version of the EQE, and while it's a rocketship of an EV, it lacked the ne'er-do-well nature of the gasoline-powered AMG versions of the E-Class. The interior is beautiful, but I can't say the same for the exterior, even with the AMG add-ons. The AMG EQE is a perfect Benz, but I wouldn't go so far as to call it the perfect AMG product." In-depth analysis: 2023 Mercedes-Benz EQE Sedan Review: A smaller, less expensive EQS   2023 BMW X1 2023 BMW X1 xDrive28i 03 View 31 Photos Quick take: The BMW X1 is the driver's choice in the subcompact luxury SUV segment. Its size and abundance of tech makes it a great all-rounder for anybody's taste, though. Score: 8.0 What it competes with: Volvo XC40, Audi Q3, Mercedes-Benz GLB, Mercedes-Benz GLA, Jaguar E-Pace, Lexus UX, Land Rover Discovery Sport, Pros: Fun to drive, great utility, traditional and handsome design Cons: Interior feels spartan, value is questionable From the editors: Senior Editor, Green John Beltz Snyder — "This segment is a competitive one, but the X1 sets itself apart as the driverÂ’s car.

Recharge Wrap-up: Tesla firmware update videos, Mercedes S500 Plug-In Hybrid

See the Tesla Model S with Firmware 6.0 in action in new videos from Teslarati. The large software update includes improved traffic-based navigation, a calendar function, updated power management, "Location-Based Smart Air Suspension" as well as other improvements. Drivers get more route options to save energy, and more control over how the car saves energy. The car can also remember ride height settings when driving in those same locations again. Additionally, you can start and drive the car without a key, just using the smartphone app. See how it all works in the videos below, the second of which focuses on pairing with the updated phone app. The California Public Utilities Commission (CPUC) has deemed ride-hailing app Uber's carpooling service illegal. The way the UberPool service is categorized by the CPUC, charging multiple riders separate fares for a single ride runs afoul of the law. The technical details are a bit convoluted, and what supporters could deem arbitrary, but Forbes delves into the details a bit further to try to make sense of California's intentions (even considering the possibility of other ride services, such as airport shuttle companies, fueling the fire). Lyft - which operates a similar service called LyftLine - and Sidecar have also received notices from the CPUC. Read more at Forbes. China's recent enthusiasm for electric vehicles could be largely attributed to a single person, Ma Kai. After the Politburo member was named vice premier, he encouraged maintaining and increasing EV subsidies when China sought to decrease them. He also seems ready to fight for more EV deregulation to encourage more clean vehicles. Read more about Ma Kai and what he's done for China's EV legislation at Automotive News. Mercedes-Benz begins deliveries of the S500 Plug-In Hybrid this month. The high-tech luxury PHEV features energy saving modes based on driver, route and traffic, and features a haptic accelerator that can signal when the driver should ease off to save power. It's powered by a biturbocharged V6 and 85-kW electric motor. Its 8.7-kWh battery offers about 20 miles of electric driving. The S500 plug-in starts at about $146,000.
