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.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.

BMW negotiates Daimler alliance, buys out car-service partner Sixt

Sixt sells its stake in DriveNow car-sharing to BMW BMW in talks with Daimler to combine car-sharing Combining car-sharing business to aid robotaxi plans FRANKFURT — Germany's BMW has bought out partner Sixt from their joint venture DriveNow, paving the way for a broader car-sharing and driverless taxi alliance with Daimler to compete against Uber and Lyft. Car rental company Sixt said on Monday it would generate an extraordinary pre-tax profit of about 200 million euros ($248 million) in 2018 from the sale of the DriveNow stake to BMW for 209 million euros. "With DriveNow as a wholly-owned subsidiary, we have all options for continued strategic development of our services," said Peter Schwarzenbauer, BMW's board member for Digital Business Innovation. "Our experience with mobility services supports our development of future autonomous, electrified and connected fleets," he said, adding that BMW aims to have 100 million customers for "premium mobility services" by 2025. The Sixt deal comes as BMW moves closer to a deal to combine its car-sharing services with Daimler's Car2Go, a person familiar with the discussions told Reuters last week. The German carmakers want to build a joint business that includes car sharing, ride-hailing, electric vehicle charging, and digital parking services, a senior executive at one of the companies said on Monday. Mercedes-Benz parent Daimler and BMW declined comment on the status of potential talks on their car-sharing business. "This is speculation, we do not comment," BMW said. The senior executive, who declined to be named because the plan is not public, said: "This will create an ecosystem which can also be used for managing robotaxi (driverless taxi) fleets." BMW would contribute its ParkNow and ChargeNow businesses to the common company, the executive said, adding that there were still differences of opinion over the valuation of Car2Go. The market for ride-hailing services currently makes up around 33 percent of the global taxi market, and could grow eightfold to $285 billion by 2030, once autonomous robotaxis are in operation, Goldman Sachs said in a recent research note. BMW and Daimler are now working on developing autonomous cars, vehicles which could enable them to up-end the market for taxi and ride-hailing services.
