Erebus Motorsport Mercedes E-Class V8 Supercar completes the field [w/videos]

Ford, Holden and Nissan introduced their V8 Supercar challengers a while back. Erebus Motorport, whose racing program got the green light not even 120 days ago, has finally shown off the Mercedes-Benz E-Class racer that will complete this year's field of entries. The first AMG race car ever to be built outside of Germany, it's an Australian-built tube-frame chassis specced to the series' Car of Tomorrow rules, fitted with body panels that channel the E63 AMG.
Supported by AMG Customer Motorsport, the 5.0-liter engine is provided by HWA in Germany, the racing arm of AMG. Regulations dictate that it have roughly 650 horsepower, a redline between 7,000 and 7,500 rpm and a torque curve that matches the parity baseline set for all cars.
Lee Holdsworth, Tim Slade and Maro Engel will drive the three team cars, each with different sponsors. Their first showing will be at the Clipsal 500 on March 3 in Adelaide, here in the US we'll get to see them in May at the Circuit of the Americas. Check out the videos below of the Erebus car starting up at its launch, and footage of all of this year's cars doing pre-season testing on track together.

Maybach Pullman, S550 4Matic coming next

Mercedes-Benz officially revived the Maybach name as a sub-brand with the reveal of the luxed-up S600 at the LA Auto Show last week, but that's only the tip of the proverbial iceberg when it comes to the German automaker's new plans for its uber-prestige marque. Motor Trend reports that Mercedes is planning two additional Maybach variants to launch in the near future, both of them also based on the S-Class. First up, we're told to expect the even longer Pullman limousine to launch, complete with Maybach treatment, at the Geneva Motor Show next March – although this model won't necessarily be offered in America. Whether it will or not, the Mercedes-Maybach S600 Pullman will be even bigger, more luxurious and more expensive than the one just unveiled. What is being planned for US customers, however, is an Maybach S550 4Matic. Mating the 4.7-liter twin-turbo V8 to all-wheel drive would be a boon for wintery upscale markets, and is reportedly a more feasible option than trying to pair the V12 to the 4Matic system. As for other model lines, we've heard rumors of a Maybach GL-Class utility in the pipeline, but have yet to receive any such confirmation. Car confirms, however, that we shouldn't expect to see AMG versions of Maybach models. The two are being cultivated as separate pillars atop the Mercedes range – one focused on performance, the other on luxury – and never the twain shall meet. The previous model line did breed a sportier Maybach 57 S, however, and we wouldn't be surprised to see a similar treatment applied to one of the new models should Daimler find there's demand. In related news, MT also reports that a new S-Class Cabriolet is coming around the corner, and that the G550 is preparing to drop its aging 5.5-liter V8 in favor of the GL's 3.0-liter twin-turbo V6.

F1 title fight gets closer | 2016 US Grand Prix recap

We ran into an old friend at the US Grand Prix: an on-form Lewis Hamilton. Reliability and proper clutch actuation helped the Mercedes-AMG Petronas driver resurrect the kind of performance we haven't seen since July at the German Grand Prix. After demolishing the previous qualifying record around the Circuit of the Americas, he put the field in his mirrors as soon as the lights went out, was never bothered by anyone behind, and crossed the finish line 4.5 seconds ahead of teammate Nico Rosberg. The drive was exactly what Hamilton needed to keep his molecule-thin Championship hopes alive. Rosberg, however, did exactly what he needed to do as well by finishing second. The German had a sketchier path to the checkered flag than Hamilton, getting pushed back to the third at the start by Red Bull's Daniel Ricciardo. Worse, Ricciardo appeared to have the pace to keep Hamilton honest ahead and hold Rosberg behind. Red Bull and Mercedes matched one another's pit stops, and it was clear the German would need more help to pass the Aussie. Rosberg didn't have to make his own luck, Ricciardo's teammate Max Verstappen made the luck for him. Ricciardo pitted on Lap 26, ceding second position on track to Rosberg. On Lap 30, Verstappen's gearbox failed while headed down the back straight. The Dutch teenager said the team told him to try to get the car back to the pits, so he dawdled through a few corners before following more team orders to pull over and park. Verstappen's parking spot and bad gearbox meant marshals couldn't push the car off the track, they needed to use a crane. That brought out a Virtual Safety Car, slowing the whole race down and allowing Rosberg to run a longer stint while losing less time on old tires. When the German came in for new tires on Lap 31 he emerged ahead of Ricciardo, and they ran that way to the end of the race, much to Ricciardo's disappointment. Sebastian Vettel claimed fourth for Ferrari, a placing perhaps due only to Verstappen and Kimi Raikkonen retiring from the race. An otherwise anonymous weekend for the scuderia called attention to itself on race day when Raikkonen had to call it a day after a botched pit stop, and Vettel couldn't make any impression on the teams ahead. Fernando Alonso rode home to a brilliant fifth for McLaren. During the first stint while rummaging around outside the top ten, the Spaniard complained about his lack of pace. By Lap 15 Alonso was tenth, on Lap 34 he was eighth.
