Mercedes-Benz previews its curvy sports-car and design future

Suggesting creases are passe for automotive design, Mercedes showed off ideas for its future styling directions this week at a forum in Germany, including previews of upcoming sports cars and sedans. We see images of a curvy sports car study (the silver car) with huge wheel arches flared out almost like pontoons. There's also what appears to be a rear-engine hypercar (white car); we've been reading reports about it for months. Additionally, there's a red sporty saloon, as Mercedes calls it, also among the photos. It features prominent rounded fenders and a bold horizontal grille. Mercedes also previewed its upcoming A-Class, in what it calls the Aesthetics A sculpture, which looks like a car covered in a red sheet. Though Mercedes says this is its next step to a purer design, creases and strong lines are still evident on the sides. Related Video:

Mercedes-Maybach GLS could become the most expensive car made in America

Mercedes-Benz International, the German automaker's manufacturing facility near Vance and Tuscaloosa, Ala., already builds the GLS SUV. Autonews reports that the coming ultra-luxe version of the large crossover, the Mercedes-Maybach GLS, will be built in Alabama as well for global markets. The most recent timelines mark the reveal in production or near-production form in China, with sales to commence next year. The next-gen series-production GLS goes on sale later this year. The gilded sub-brand previewed a wild concept last year in China called the Vision Mercedes-Maybach Ultimate Luxury, which blended the tall profile of an SUV with the truck of a sedan on donk wheels. Based on spy shots, none of that fancy will make it to production. Both the Maybach and AMG versions of the GLS ride on fat rubber but look thoroughly traditional. The treasure will be inside. Autonews said China accounts for roughly 75 percent of Maybach S-Class sedan sales. That suggests the GLS in baroque trim will emphasize chauffeured luxury touches like rear captain's chairs and lots of rear legroom. Pricing estimates figure $200,000 to get in the door. That would put the SUV right in line with the Lamborghini Urus and a couple stacks of Benjamins above the Bentley Bentayga, with much the same likely audience. One analyst said, "The ultra-high-net-worth kids want something different, and these ultraluxury SUVs certainly fit that," while another opined on its "appeal to the Kardashians and hip-hoppers, if they want something slightly different to the G-Wagen." A $200K MSRP would also comfortably make the Maybach GLS the most expensive new car built in America, taking the title from the Acura NSX. With a great price comes great power, said to be a twin-turbo V8 with more than 560 horsepower. The coming GLS 450 will make do with somewhere around 360 hp. The Alabama plant, which also builds the GLE, GLE Coupe, and C-Class, is also undergoing a $1 billion upgrade to more than double the size of the facility, making lines for battery production and EQ-series vehicle assembly,

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.
