US buyers show little interest in big hybrids

The idea of producing large, luxury-vehicle hybrids is turning into a "what were they thinking?" exercise in futility, USA Today reports. General Motors is discontinuing hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon SUVs, while Mercedes-Benz and Toyota's Lexus division are doing the same with their S-Class hybrid and LS hybrid sedans, respectively. The culprit? Big price increases for fuel economy improvements that border on the unimpressive. Granted, the Escalade hybrid gets 31 percent better fuel economy than the standard version, but that still maps out to a combined fuel-efficiency rating of just 21 miles per gallon. That can be seen as a worthwhile increase, if it didn't cost over $8,000 extra. The 2014 Escalade Hybrid, for example, starts at $74,425 while the non-hybrid can be had for $66,295. Meanwhile, the Lexus full-size hybrid costs $6,000 more than the regular version but only gets 1-2 mpg better combined fuel economy. The result of all these high costs? Low sales. Through April, GM sold 82 of its hybrid SUVs and pickups, down from 541 a year earlier. And the LS hybrid sales were in single-digit territory for April. That isn't stopping Lexus from promoting its hybrids as the right solution (with the wrong facts), though. There are still automakers giving big hybrid vehicles a shot, though. Nissan's Infiniti division is selling a hybrid version of its QX60 and says an impressive 10 percent of QX60 buyers choose the hybrid, which costs just $3,000 more. Looks like money talks.

The BMW 8 Series leads this month's list of discounts

Whether you prefer the sleek looks of a sport coupe, the wind-in-your-hair exhilaration of a convertible or the flexible practicality of a four-door sedan, BMW has an 8 Series to suit your fancy. And if you're in the market right now, you may find that your local BMW dealership is willing to take $18,124 off the sticker price. That figure comes courtesy of TrueCar, and it reflects the discount buyers are getting off the 8 Series' average $122,395 retail price. Most of the 8 Series models in American showrooms today are 2019 models, and that's the model year to which the discount above applies. This represents the largest discount on a new car in America this month, based on the dollar amount off the car's sticker price, and the third largest discount by percentage. And it means the average transaction price for a 2019 BMW 8 Series is hovering at $104,271. 2020 BMW 840i Gran Coupe View 38 Photos BMW offers two distinct versions of the 8 Series, the 335-horsepower 840i with rear- or all-wheel drive, and the 523-horsepower 850i, which comes standard with BMW's xDrive all-wheel-drive system. If you want to step even further up the performance ladder, there's the M8, but that 600-horsepower monster is getting a much smaller $6,150 discount. If you're not into BMWs, the 2019 Mercedes-AMG GT boasts the second largest monetary discount this month, with buyers averaging $16,713 off the Benz's $176,035 sticker price. Another Mercedes, the S-Class, is next with a $11,452 discount. After that comes a pair of Maserati sedans, the Quattroporte and Ghibli, each with discounts of around $11,000. Since the Ghibli's base price is so much lower than that of its larger sibling, that represents a much larger 13.5% cut from its average retail price of $81,384 for an out-the-door cost of $70,373.

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.
