Rosberg survives the Mexican mess | 2016 Mexican Grand Prix recap

Roughly ten messy laps defined the Mexican Grand Prix – five laps at the start and five at the end. Those laps included a couple of actual wrecks and a few more near wrecks that turned the entire day into chaos. To have any chance of winning the 2016 Driver's Championship, Lewis Hamilton needed to get his Mercedes-AMG Petronas across the finish line ahead of teammate Nico Rosberg. Once again we got a weekend full of vintage Hamilton, the Brit dominating the from Friday to Sunday, except for the first corner of the first lap. Pole-sitter Hamilton reached Turn 1 clearly in front of the field. But he couldn't make the corner and stay on track, so he zipped into the runoff area and over the grass, rejoining at Turn 3 still ahead of the field. The stewards didn't penalize Hamilton, one commentator's explanation being that Hamilton "was not battling another car." The non-action left car #44 to enjoy a lights-to-flag win. At that very same corner, Rosberg also availed himself of the runoff area. His infraction seemed destined to incur a penalty until replays showed that Max Verstappen in the Red Bull slid wide and bumped Rosberg, causing the German to go off track. No penalties were handed out there, either. Verstappen would return to hound Rosberg later in the race when angling for second place. Verstappen took a stab through Turn 4 on Lap 50 of the 71-lap race, but ran off the track and lost touch with the Mercedes by Lap 55. Ferrari got half of its strategy right in Mexico, putting Sebastian Vettel hard on the charge in the final stint. The German got within DRS range of Verstappen on Lap 67, with Red Bull's Daniel Ricciardo a little more than a second behind Vettel. On Lap 68, Verstappen pulled the same move as Hamilton at the beginning of the race: the Dutchman ran wide through Turn 1, zoomed over the grass and rejoined the track at Turn 3, staying ahead of Vettel the whole time. With three laps remaining, the stewards chose to investigate after the race. In spite of Verstappen's own team telling he probably needed to cede position to Vettel, Verstappen stayed in front and slowed just enough to put Vettel under threat from Ricciardo. On Lap 70 Ricciardo had closed up to Vettel's gearbox. Headed for Turn 4, Vettel swung outside to take the corner. When Ricciardo moved inside to pass, Vettel moved inside to block the Aussie while both cars were in the braking zone. The Ferrari made light contact with the Red Bull, but Vettel held his position through Turn 5.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Mercedes GLE63 AMG Coupe teased

The very concept of the luxury crossover coupe often gets flamed for being not only ugly, but also impractical. However, after years of letting BMW blaze the trail with the X6, Mercedes-Benz recently entered the field with the GLE-Class Coupe. Now, it's time to add a little more pepper to the package with the newly teased GLE63 AMG Coupe. The video above gives a solid look at the three-quarters perspective of this high-performance high-rider. Compared to the standard version buyers get a different front bumper with larger air intakes and an arching wing that almost appears to be floating in space. Flashes in the clip show off AMG branding for the brake calipers, steering wheel and seats, as is expected. This is clearly not a vehicle that'll appeal to everyone, but it offers an alternative to the latest BMW X6 M with 567 horsepower and 553 pound-feet of torque. Mercedes isn't saying what lies under the hood of the GLE63 AMG Coupe yet. Although given the name, we suspect a version of the brand's 4.0-liter twin-turbocharged V8 is the likely choice. It's offered in the latest C63 AMG with either 469 or 503 hp. The debut for this CUV coupe is possible at the upcoming Detroit Auto Show, where the standard GLE Coupe will be unveiled.
