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.

Aston Martin signs Letter of Intent for technical partnership with AMG

A little over two months ago came reports that Daimler and Aston Martin were in talks, again, about "supply and technical-cooperation agreements." The next step has been taken with Aston Martin announcing that it has signed a Letter of Intent that looks "towards a technical partnership" with Mercedes-AMG GmbH, and the two companies aiming to have definitive agreements done by year's end.
While it will get to use certain electric and electronic components from AMG, the true golden egg for the maker of the Vanquish will be the ability to develop a new line of "bespoke V8 powertrains" that will be fitted to "a new generation of models." In return for opening up the larder, Daimler will get a non-voting stake of up to five percent of Aston Martin.
Nothing else is being said about the tie-up for the moment, but there's a press release below with a few more details.

2015 Russian Grand Prix was full of crashes and DNFs

Mercedes-AMG Petronas non-executive chairman Niki Lauda said of Lewis Hamilton's race-day domination this year, "The guy is driving like a god." Qualifying is another story, though – teammate Nico Rosberg taking pole proved that sometimes deities have to settle for second on the grid. Williams driver Valtteri Bottas surprised himself and his team with third place, half a second behind Hamilton but 0.05 sec ahead of the first Ferrari driven by Sebastian Vettel, while a mistake on Kimi Raikkonen's final flying lap left him in fifth, 0.4 sec behind Vettel. The Sahara Force India team had a good showing, with Nico Hulkenberg qualifying sixth just ahead of teammate Sergio Perez in seventh. It's the first time they've had both drivers in the top ten on the grid since the 2014 British Grand Prix. Romain Grosjean is leaving the stormy waters of Lotus at the end of the year for the unknown waters of Haas F1, but he made the shoestring operation look really good before Renault takes over by taking eighth place on the grid. Max Verstappen qualified well again with ninth in the Toro Rosso, ahead of the first Infiniti Red Bull Racing of Daniel Ricciardo in tenth. Red Bull driver Daniil Kvyat lined up eleventh for his home grand prix, certainly a disappointment after locking up fifth place on the grid last year in a Toro Rosso. When Pirelli brought soft and supersoft compounds to Sochi, the company said it hoped this year's race would be better than last year's. We're sure this first-lap mishap isn't what they meant. Rosberg and Hamilton dragged it down to Turn 1, with Rosberg getting the inside line. Hamilton had to go wide at Turn 2 as Rosberg fought to hold position, but they left a mess in their wake: Hulkenberg spun going into Turn 2 and stopped in the middle of the track, and Marcus Ericsson in the Sauber – who'd started 16th – collided with him. Both cars were out of the race immediately, and the Safety Car came in. The Safety Car returned to the pits on Lap 3 Rosberg led the field, but just two laps later the German complained of a sticking throttle pedal. Two laps later he had to retire, unable to drive the car properly. That put Hamilton at the front, and we've seen that race a bunch of times before. He built a double-digit lead and never lost it.
