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.

Ethanol is being help up by rail transport, according to ethanol producer Green Plains. More and more stations are carrying E15 blend gasoline, but grain producers have complained that crude oil is given higher priority by the rail lines shipping it, which rail companies deny. Union Pacific and BNSF Railway say they are stepping up service to make sure that ethanol can be shipped reliably to customers. Read more at Omaha World-Herald. General Motors "has placed a significant bet [on] the electrification of the automobile," says CEO Mary Barra. In a speech to the Detroit Economic Club this week, she spoke about the Chevrolet Volt, and its importance to GM's future. While Barra admits the Volt's success has been "not everything we wanted," it has provided experience, and shows that EVs have "an important role in the future of GM." The new Volt is more refined, stores more energy, has longer range, uses less fuel and is a big investment for Michigan. She announced that the new Volt's electric drive system will be built in Warren, and that all of its major components will be made in Michigan. "Silicon Valley doesn't have a corner on the market for innovation, creativity and drive," says Barra. "These qualities exist here – in this region – as well."
