Lewis Hamilton beats Sebastian Vettel in Chinese Grand Prix

SHANGHAI (Reuters) - Lewis Hamilton mastered Shanghai's changing conditions and stayed clear of squabbling rivals to win the Chinese Formula One Grand Prix on Sunday. The Briton eased his Mercedes across the line 6.2 seconds ahead of Ferrari's Sebastian Vettel. Max Verstappen, who started 16th, finished a surprise third to hand his Red Bull team their 100th podium. It was Hamilton's 54th career win and a record fifth in Shanghai. But it was the triple champion's first this season and returned Mercedes to the top of the podium after Vettel won last month's season-opening race for a resurgent Ferrari. "I'm so happy with my first win of the year and I can't believe it if I'm honest," said Hamilton after the race, which also handed him his 106th podium, putting him joint second with Alain Prost on the list of drivers with most rostrum results. "What I said to Sebastian as I left the last race ... I said I'm coming back in the next one. When I got on the podium it was like 'I told you'." MOTOR-F1-CHINA/ View 12 Photos Hamilton, who finished second to Vettel in Melbourne, heads into the next race in Bahrain in a week's time tied on points with the German. Mercedes, meanwhile, lead the constructors' standings by one point over Ferrari. Hamilton started from pole position, but the conditions were a bit of a lottery for all the drivers with the track damp in patches but drying quickly. He kept the lead off the line ahead of Vettel, who came under investigation for lining up out of position on his grid slot. The German, though, stayed second, fending off Valtteri Bottas in the other Mercedes, who had started third. Lance Stroll, the 18-year-old rookie, spun off the track on the first lap after making contact with Force India's Sergio Perez. The Canadian beached his Williams in the gravel, bringing out the virtual safety car. Vettel took the opportunity to dive into the pits to change to dry weather tires. His gamble backfired when Antonio Giovinazzi — standing in for Pascal Wehrlein at Sauber — crashed, bringing out the actual safety car two laps later. The four-times world champion found himself bottled up behind Ricciardo and his slower team-mate Kimi Raikkonen, costing him valuable time. As the trio squabbled for position, Hamilton pulled clear at the front. By the time Vettel managed to get past, with a series of spectacular overtaking moves that included banging wheels with his former team-mate, Hamilton was too far ahead.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

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.
