Mercedes-AMG to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.

Smart brand might be doomed

Reports are painting a less than rosy picture of the Smart brand's future. The Daimler-owned carmaker is going fully electric in 2020, but that might not be enough to keep it alive for long. Inside sources, quoted by Automobile Magazine, are saying Renault is likely to pull out of the partnership that created the current Smart ForTwo/Renault Twingo pairing introduced in 2014. The two rear-engined cars share a platform, and when the current Twingo is done for, Renault might want to part ways. In addition, Mercedes isn't willing to prop up Smart on its own, and there is a possibility that the entire Smart brand could be shuttered by 2026. A previous joint venture was the ForFour hatch co-developed with Mitsubishi, and despite the ForFour name living on in the current generation rear-engined car, the earlier FWD hatchback has quickly been forgotten. Not long ago, Smart presented its Forease open-top concept to give customers a glimpse of what future Smart cars would look like, but at its heart the Forease was still a current Smart dressed up with concept car details. The next-generation Mercedes-Benz A-Class is to be signed off in 2021 for a 2025 introduction, and it can be underpinned by a more flexible, fully scalable platform that could also serve to support a new entry-level Mercedes-Benz vehicle that could render the separate Smart brand pointless. Then there's Geely, who now owns nearly 10 percent of Daimler, and who is partnering with Daimler to launch a new "premium" ride-hailing venture in China. As Geely develops its mobility solutions, it is likely to keep an eye on Smart: Smart cars have been car-sharing staples around the world for quite a while, from users such as Car2Go. Automobile Magazine says that if a Smart is co-developed with Geely, it might suit the Chinese market well, but a global business case might be challenging. In any case, if Smart wants to survive beyond the current Renault partnership, the new model should be agreed upon quickly, and it must be based on a platform flexible enough to support full electric drive. Reportedly, there are now ongoing feasibility studies for a fully electric Daimler "U-Class," which would include a Smart-like three or five-door hatch with two wheelbase options, a ride-sharing shuttle with autonomous capabilities, and an urban delivery panel van. But Smart must justify itself for the upcoming decades, or the future Daimler products that occupy its niche will be wearing a three-pointed star instead.

Mercedes-Benz C-Class 'bleeding seat' problem resurfaces [UPDATE]

UPDATE: We received the following statement from Mercedes-Benz: "In rare instances, we incorrectly ordered some of the replacement parts for the seating surfaces. The approved replacement parts will not demonstrate the previous symptoms." It appears Mercedes-Benz has another problem with "bleeding seats" in 2015 C-Class sedans. As we reported in January, an oily residue has been appearing on some versions of the C-Class with man-made MB Tex upholstery, making it look as though the seats were grimy or "bleeding." Mercedes issued a technical service bulletin to its dealers to remedy the problem, but now we're hearing the fix isn't complete. Small parts of the seats – the rear bolsters and a piece below the center armrest – weren't replaced during service and then developed the oily reside again, a source tells us. This occurred within a few days of their service appointment. The dealer followed Mercedes' instructions, our source said, and their C-Class appears to have been one of the first cars fixed. "I'm absolutely flabbergasted at this point ... The new C-Class is such a good car. This is just a shame," they told Autoblog. The bleeding seat issue appears to affect US-built C-Class models with the MB Tex vinyl and possibly other interiors. The bleeding often occurs when a car has been sitting in the cold and then heats up quickly. The number of cars affected is unclear, though the C-Class owners have been vocal in the MBWorld.org forum. At the time of our original report, Daimler AG, parent of Mercedes-Benz USA, said it was aware of the issue and that no injuries had been reported. The residue usually washes off with soap and water. The National Highway Traffic Safety Administration had no recalls, complaints or investigations recorded about the issue as of Wednesday. The fix at the dealer involves changing out the headrest and seat covers, except for a part of the passenger seat that needs to be calibrated by the factory, according to the bulletin. The C-Class is a critical car for Mercedes as it battles BMW, Lexus and others for supremacy in the ultra-competitive luxury segment. The C-Class, which launched last fall, is moving upmarket as Mercedes reshuffles its lineup with the addition of the CLA sedan. The C-Class was the company's best-selling model in January with volume of 6,236 units.
