Mercedes-Benz S63 AMG officially teased in mini video

The followup to the Mercedes-Benz S550, the S63 AMG, will sport a biturbocharged V8 that will likely turn out around 550 horsepower. The new engine is probably the 5.5-liter, biturbocharged V-8 that's been popping up in everything from the ML63 to the E63 AMG. The front fascia is more aggressive, which shouldn't come as a surprise, while a meaty exhaust setup can be found out back.
We managed to pick all that up from a short, 17-second video posted by MB. The original video that unveiled the S63 AMG has since been pulled down, making this YouTube clip the best look we now have at the new super sedan, at least until the Germans give up the goods for real.
Be sure to check out the video below, along with our original posting on the S63 AMG.

2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

2015 Brazilian Grand Prix is the same as it ever was

At this point, we hope Nico Rosberg is planning to carry his current qualifying form into the 2016 season and back it up with the same kind of race-day cojones he showed winning the race in Mexico City two weeks ago. The Mercedes-AMG Petronas driver got it right enough again on Saturday afternoon to take his fifth consecutive pole position ahead of teammate Lewis Hamilton by almost a tenth of a second. It's the same one-two from Brazil last year. The bad news for the rest of the field is that the winner in Brazil the last seven years has been one of the two drivers on the front row. Last year it was the Williams duo that lined up behind Mercedes, this year it's Ferrari. Sebastian Vettel plays the stalking horse, securing third in his Ferrari ahead of teammate Kimi Raikkonen in fourth. Williams driver Valtteri Bottas actually qualified in fourth, but he had to serve a three-spot grid penalty for passing under red flags in Free Practice 2, so he started sixth. That promoted Sahara Force India driver Nico Hulkenberg up to fifth. Daniil Kvyat was the quickest representative from Infiniti Red Bull Racing, getting into seventh even with a Renault power unit that's weak on some of the key stretches at the Interlagos track. Felipe Massa had the second Williams in eighth, in front of the second Red Bull driven by Daniel Ricciardo in ninth. Toro Rosso hasn't confirmed its drivers for next year but Max Verstappen keeps making it hard to look elsewhere, taking 10th. Rosberg is working nearly the same trick he pulled last year: drive like a second driver for most of the year, drive like a world champion for the last quarter of a season. He pulled away at the start and covered Hamilton just enough on the run to the first corner to keep Hamilton on the outside. By the end of Turn 1 the German had the lead and didn't give it up for the rest of the race outside of pit stops. Without overwhelming pace to pass and unable to follow closely, Hamilton could do nothing except ask his team for a different strategy to go for the win. When Mercedes told him "No," trying to protect Rosberg's second place in the championship ahead of Vettel, that was the race. Just like last year, Rosberg and Hamilton finished one-two. Vettel, Raikkonen, Bottas, Hulkenberg, and Kvyat drove lonely races to finish in positions three through seven.
