Aston Martin and Mercedes will share F1 safety car duties

LONDON — Aston Martin is set to join Mercedes next season as a provider of Formula One's official safety cars, according to media reports on Tuesday. Racefans.net reported that Aston Martin would supply safety and medical cars at 12 of the 23 scheduled races in key markets, with the existing Mercedes cars used at the rest. It said Aston Martin's new DBX SUV, which uses a Mercedes-AMG V8 engine, would be used as a medical car. There was no official confirmation from Aston Martin or Mercedes. Sources indicated to Reuters that the report was accurate, however. Mercedes has been the official provider of the cars, which are deployed in the event of an incident or bad weather to keep the field lapping safely, since 1996 but that deal runs out at the end of this year. A shared supply would make sense for both carmakers, who already have close ties. Aston Martin's executive chairman Lawrence Stroll also owns the Racing Point team, who will race as Aston Martin from next season with four times world champion Sebastian Vettel arriving from Ferrari. Mercedes, a part of Daimler, is set to raise its stake in Aston Martin to up to 20% by 2023. Toto Wolff, principal of the Mercedes factory team, also has a private stake in Aston Martin.

Super Bowl commercials: Steven Tyler, Emerson Fittipaldi, Keanu Reeves and more

Sunday is Super Bowl LII, which means America will immerse itself in high-calorie potluck fare, garish halftime-show entertainment (Justin Timberlake, bringing sexy back, but not that kind), the most expensive and over-the-top TV ads of the year, and — oh yeah — a football game between two teams connected by Amtrak's Northeast Corridor line. What else you gonna do on the first Sunday of February? As usual, automakers plan big, splashy TV spots to reach all those gajillions of eyeballs glued to the teevee, though the list may be shorter than in previous years. Here's a roundup of what we know is coming. Hyundai Hyundai will test the football/futbol divide with a 60-second spot starring a youth-soccer ref who arrives for the game dramatically and just in time in his 2018 Kona. Only it's Super Bowl Sunday, so he — along with the two coaches, and apparently most of the parents — are eager to get on with their game-day plans. Advantage: football, being the message, we guess. The ad does make a quick plug for Hyundai's BlueLink nav system, but this is only nominally about the car. This content is hosted by a third party. To view it, please update your privacy preferences.

Kia This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. The Korean automaker will put Aerosmith frontman Steven Tyler behind the wheel of its new Stinger on an abandoned racetrack. The former " American Idol" host promptly puts it into reverse, going back to his '70s heyday, courtesy of some CGI, to the strains of "Dream On" played backwards. Trotting out an almost-70-year-old to relive some classic rock glory fits the Super Bowl template to a T. Two-time Formula One and Indianapolis 500 champ Emerson Fittipaldi also makes a cameo. It airs in the third quarter. Lexus This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Lexus teams with Marvel Studios to preview its forthcoming movie "Black Panther," which arrives in theaters Feb. 16. In "Long Live The King," the Black Panther, a.k.a. King T'Challa, played by Chadwick Boseman, dispatches some bad guys to recover stolen Vibranium after clinging to the roof of a speeding 2018 LS 500 F Sport, driven by co-star Danai Gurira.

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.
