Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

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.

Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.
