Chris Harris and David Coulthard wring out a Mercedes Fintail at the N"urburgring

If there's one thing we've learned from the latest video from Drive, it's that the combination of Chris Harris and David Coulthard will produce some very quotable moments. Take this exchange, for example.
DC: "We are by some way the slowest."
CH: "But we're in a class of three cars, apparently."

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.

When Android Automotive goes in the dash, Google wins — and automakers lose data

You've gotta hand it to Google for the way the Silicon Valley tech giant has made indelible inroads into the car on multiple fronts. The most obvious is with its pioneering self-driving car technology that's caused car companies to get their act together on autonomous vehicles — and also collaborate with Google. Google has more directly extended its influence and data-mining capabilities into the car with its Android Auto smartphone-projection platform that most major automakers have adopted along with Apple's CarPlay. And now it's preparing to dig even deeper into dashboards by deploying its open-source operating system, Android Automotive, beginning with Audi and Volvo. Volvo recently announced that its next-generation Sensus infotainment system will run Android Automotive as an OS and include Google's Play Store for cloud-based content, Maps for navigation and Google Assistant for voice recognition, which can even command a car's climate control. By embedding Google in the dash, Volvo says owners will get an improved connected experience. "Bringing Google services into Volvo cars will accelerate innovation in connectivity and boost our development in applications and connected services," Volvo senior vice president of R&D Henrik Green said in a statement. "Soon, Volvo drivers will have direct access to thousands of in-car apps that make daily life easier and the connected in-car experience more enjoyable." Having Android Automotive onboard could benefit drivers — and provide a big win for Google, since it opens a deep and lucrative new data-mining vein for the company. But it's a wave of a white flag for car companies when it comes to delivering their own cloud-based content and services. It also represents a massive data giveaway and, for Audi, a reversal of earlier reservations about letting Google get too much access to car data. Not long after Android Auto and Apple CarPlay were introduced in 2014 and most automakers eagerly embraced the technologies, several German automakers second-guessed their decision when they realized what was at stake: data. At a conference in Berlin in 2015, Audi CEO Rupert Stadler said car owners "want to be in control of their data, and not subject to monitoring." A few months earlier, Stadler stated that "the data that we collect is our data and not Google's.
