2015 Russian Grand Prix was full of crashes and DNFs

Mercedes-AMG Petronas non-executive chairman Niki Lauda said of Lewis Hamilton's race-day domination this year, "The guy is driving like a god." Qualifying is another story, though – teammate Nico Rosberg taking pole proved that sometimes deities have to settle for second on the grid. Williams driver Valtteri Bottas surprised himself and his team with third place, half a second behind Hamilton but 0.05 sec ahead of the first Ferrari driven by Sebastian Vettel, while a mistake on Kimi Raikkonen's final flying lap left him in fifth, 0.4 sec behind Vettel. The Sahara Force India team had a good showing, with Nico Hulkenberg qualifying sixth just ahead of teammate Sergio Perez in seventh. It's the first time they've had both drivers in the top ten on the grid since the 2014 British Grand Prix. Romain Grosjean is leaving the stormy waters of Lotus at the end of the year for the unknown waters of Haas F1, but he made the shoestring operation look really good before Renault takes over by taking eighth place on the grid. Max Verstappen qualified well again with ninth in the Toro Rosso, ahead of the first Infiniti Red Bull Racing of Daniel Ricciardo in tenth. Red Bull driver Daniil Kvyat lined up eleventh for his home grand prix, certainly a disappointment after locking up fifth place on the grid last year in a Toro Rosso. When Pirelli brought soft and supersoft compounds to Sochi, the company said it hoped this year's race would be better than last year's. We're sure this first-lap mishap isn't what they meant. Rosberg and Hamilton dragged it down to Turn 1, with Rosberg getting the inside line. Hamilton had to go wide at Turn 2 as Rosberg fought to hold position, but they left a mess in their wake: Hulkenberg spun going into Turn 2 and stopped in the middle of the track, and Marcus Ericsson in the Sauber – who'd started 16th – collided with him. Both cars were out of the race immediately, and the Safety Car came in. The Safety Car returned to the pits on Lap 3 Rosberg led the field, but just two laps later the German complained of a sticking throttle pedal. Two laps later he had to retire, unable to drive the car properly. That put Hamilton at the front, and we've seen that race a bunch of times before. He built a double-digit lead and never lost it.

Your guide to vehicle subscription services

They might be extremely limited in scope because of location availability, but vehicle subscription services are a growing trend that most luxury manufacturers are jumping on. Plans are expensive, but you're paying for much more than just the car typically. We highlighted four of the larger plans with a few more listed at the end. Care by Volvo Volvo launched its subscription service last year with its brand-new XC40. It was the only vehicle available for a time, but subscribers can now get an S60 sedan as well. Subscriptions are for two years, with the monthly price including insurance, a concierge service, wear-and-tear item replacements and all maintenance. You'll be able to drive 15,000 miles per year with whichever Volvo you choose, and although there are no options to extend that mileage, you can swap cars after a year. Pricing for the XC40 is $650 per month in base trim, while an S60 can be as expensive as $850 for the R-Design. Volvo's plan is to offer more cars soon through the service, but it's relatively limited compared to others right now. Porsche Passport Porsche has two levels in its subscription service: Launch and Accelerate. Launch will cost $2,000 per month and give you access to the Cayman, Boxster, Macan and Cayenne. All of those but the Cayenne can be had in "S" trim as well. Accelerate is where the fun really starts. For $3,000 per month you can choose from a fleet of 911s, including the S, 4S, Cabriolet and Cabriolet S. If those aren't enough, you can also get the Panamera 4S, Macan GTS and Cayenne S. There are no mileage limits and you can change vehicles as often as you'd like. Also included in the price is insurance, repairs, detailing and any maintenance. It might be extremely expensive and limited to Atlanta only, but this subscription service is second-to-none for what you get. Audi Select Audi just launched its subscription car service, and it's offered in one version for a flat fee of $1,395 per month. For that you'll have access to five different cars including the A4, S5 Coupe, A5 Cabriolet, Q5, and Q7. Not a bad range of vehicles, but it would've been neat to see the recently updated A7 in there too. Maybe in time. Like the others, insurance and maintenance are wrapped up in the price. Audi is allowing for unlimited miles and two car swaps per month here. In addition to that, you'll get two days of free rentals through Audi's Silvercar rental agency should you go on a trip.

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.
