Mercedes-Maybach SL 680 Monogram Series gives the rich and famous what they want

TOPANGA, Calif. – Give the people what they want, right? Especially if they're extremely wealthy. And possibly famous.  Apparently, the requests for a convertible Maybach from existing owners and/or celebrities were so frequent and insistent that the uber-luxury offshoot of Mercedes-Benz finally decided to give them just that. The 2025 Mercedes-Maybach SL 680 Monogram Series answers the call. While all other Maybachs are based on a Mercedes-Benz, this is the first Maybach to be based on a car developed by AMG: the current-generation SL 55 and SL 63. This presented a greater challenge to engineers than past efforts. Although a sportier Maybach was intended (as opposed to modern Maybach's first drop-top effort, the Maybach S 650 Cabriolet), the SL 680 is, not surprisingly, seeking a much different dynamic end goal than its AMG-only cousins. According to Maybach product manager Hannes Meyer, the far shorter wheelbase than the Maybach norm was a particular challenge in making sure that its convertible offering maintained "the same ease and nearly floating driving experience" expected of the brand. To that end, the Maybach SL shares the SL 63's air suspension and trick AMG Active Control interconnected hydraulically controlled dampers, but the tuning is changed, especially with the rear air springs as the driver sits closer to those. Meyer says the damper valves in particular have a greater range between sportiness and comfort than the SL 63. The steering system is totally Maybach-specific, including a different ratio and more upright front camber, resulting in what Meyer described as a more stable and less aggressive setup than what you'd find in the SL 63.  Before you start looking for a 6.8-liter engine in the Mercedes arsenal, remember that those numbers don't really mean anything anymore. The Maybach SL 680 has exactly the same 4.0-liter twin-turbo V8 as the SL 63 good for 577 horsepower and 590 pound-feet of torque. The nine-speed AMG transmission is the same in terms of hardware, but it has totally different software. In particular, the 2-3 and 3-4 shifts are most different in order to provide a smoother, more Maybach acceleration experience. The 4Matic+ all-wheel-drive system is also shared, but is programmed to have a more balanced front-to-rear power split than the rear-biased AMG. Finally, the exhaust has been retuned. Meyer said that up to 2,800 rpm, the exhaust isn't quieter than what you'd experience in the AMGs, it just has a different tone.

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.

The Mercedes-Benz S-Class leads this month's list of discounts

Like last month, the biggest discounts car buyers will find on new vehicles are all applied to expensive luxury sedans. Unlike last month when there were two, there isn't a single Rolls-Royce to be found anywhere in the top five. Sorry, one-percenters. But just because the pinnacle of European luxury isn't represented doesn't mean there aren't big discounts to be found on lovely luxury sedans. In fact, this month's list is led by the 2020 Mercedes-Benz S-Class, a technological wonder that coddles its driver and passengers with all the bells and whistles the German brand has to offer. The Mercedes-Benz S-Class is offered in many shapes and sizes with several powertrain options. That means there will be a huge variance in prices across the model range, but on average, 2020 S-Class buyers are seeing $11,803 lopped off the car's $109,447 sticker price, leaving an average transaction price of $97,644. That's a savings of nearly 11%. It's worth noting that there's a new S-Class for 2021, but the 2020 edition is still a lovely machine. Up next is the Porsche Taycan, sitting in second place just like it did last month. Buyers are seeing average sticker prices of $125,736 but are paying $113,938. That's a savings of $11,798 — or about 9.4% — off the price on the window sticker. As was the case last month, we're not sure how many of the Taycan's buyers will be able to claim tax rebates due to the Taycan's status as an electric vehicle, but that could potentially represent a further cut off the car's sticker. Rounding out the top three for the month of July is the Maserati Ghibli. With an average discount of $10,161 that represents a whopping 14.3% of the car's sticker price, this Italian luxury sedan actually leads the list of vehicle discounts when ranked by percentage. And if you're a Maserati fan but the Ghibli isn't your cup of espresso, the Levante crossover and larger Quattroporte sedan are also seeing very large discounts.
