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.

Mercedes-AMG GT attacks Circuit of the Americas

Mercedes-Benz is having a banner year with its Formula One team. Through 2014, the constructor has 454 championship points; ahead of its nearest competitor (Red Bull-Renault) by a margin of 182 tally marks. We're sure they can almost taste the champagne.
It's fitting then, and a little big cocky in a good way, that Mercedes has released a video of its newest sports car at an F1 venue. In this case, the car is the lovely Mercedes-AMG GT S, and the racetrack is Austin's Circuit of the Americas.
Having seen the official photo set and scratched the surface of the technical specifications earlier this week, we're excited to finally hear the thing run. As you might guess, the deployment of 503 horsepower and 479 pound-feet of torque from the twin-turbo V8 is a motivating experience. Crank up your volume, and hit that play button. (Oh, and Mercedes shot the thing in 4K, too, so those of you with expensive televisions/monitors should take heed to the settings.)

Mercedes rules out hybrid supercar, promises SLS successor

The recent Geneva Motor Show was a festival of hypercars, with the presence of not one, but three over-the-top debuts: the Lamborghini Veneno, McLaren P1 and Ferrari LeFerrari. The latter two have hitched their carbon fiber bumpers to the electrification bandwagon by using hybrid-electric powertrains not entirely unlike the propulsion systems we've come to know in cars like the Toyota Prius and Chevrolet Volt. Does that mean the flow of electrons up the four-wheeled food chain will eventually consume our hallowed supercars? Not if AMG has anything to say about it.
AMG Director of Vehicle Development Tobias Moers recently confirmed that not only will there be a successor to the Mercedes-Benz performance division's SLS AMG, he notes that its internal combustion engine will most definitely not be sharing living quarters with an electric drivetrain. Instead, AMG plans to focus on further pushing the power and efficiency envelope of the internal combustion engine and advancing the use of lightweight materials to achieve their goals. The first example of this effort can be seen in the new SLS AMG Black Series that incorporates many weight-saving techniques to shed some 154 pounds from the SLS AMG GT (above), which itself is lighter than the standard SLS AMG.
Furthermore, Moers remarks that his company is happy to leave the hypercar segment to companies like Ferrari and McLaren. He admits that, "Ferrari in the hyper-car segment is still a different brand than AMG. We have to be honest..." So rather than taking the SLS further upmarket to do battle with bulls and stallions, Moers hinted that the next-generation SLS may be joined by another performance model that fits neatly between itself and the C63 AMG.
