Vettel steals victory from Hamilton in Australian Grand Prix

MELBOURNE, March 25 – Sebastian Vettel made full use of the virtual safety car to sneak in front of Lewis Hamilton and hold off the frustrated champion to win Formula One's season-opening Australian Grand Prix on Sunday. The Mercedes engine's infamous 'party mode' that delivered Hamilton a blistering pole lap on Saturday could do little once Ferrari's Vettel nosed ahead when re-entering from pit-lane midway through the race at Albert Park. Pole-sitter Hamilton had appeared set to coast to victory with a clear pace advantage but the race turned on its head with the safety car, which was called after Romain Grosjean's Haas failed and rolled to a stop at turn two. In another bonus for Ferrari, Kimi Raikkonen finished third, fending off Red Bull's Daniel Ricciardo and leaving the unlucky Australian still searching for a first podium in his home race. "We got a bit lucky." Four-times world champion Vettel claimed a 48th overall win and his third in Melbourne following his victories at Albert Park last year and in 2011. "It was needless to say we got a bit lucky with the timing of the safety car," the German, who had started from third place and inherited the lead when Hamilton and Raikkonen had pitted earlier in the race, told reporters. "It's not the easiest track to pass." For Hamilton, the result was a bitter pill to swallow and had echoes of last year's race. Vettel also managed to re-enter in front of him from pit-lane in 2017 before burning away to victory while the pole-sitting Briton was blocked by traffic. Mercedes boss Toto Wolff said his team had miscalculated the margin between the cars during the safety car period. "We thought we had enough margin," he told the BBC. "It must have been a software bug in the system that caused us to get it wrong. We are digging deep now to understand where we had a problem." "I don't understand what's happened." Hamilton, who cockily spoke of "wiping the smile off" Vettel's face with his pole lap on Saturday, battled to keep positive. "Even now I don't understand what's happened," the 33-year-old told reporters. "I did everything I believe I was supposed to do." After the pit-lane setback, Hamilton drove hard to reel in Vettel and battled back after taking a slide at a corner that blew out the lead to nearly three seconds. But he finally waved the white flag in the closing laps to preserve the car for future races.

Hamilton wins at Monza, takes Formula One lead from Vettel

MONZA, Italy (Reuters) - Lewis Hamilton won the Italian Grand Prix for Mercedes on Sunday with an utterly dominant drive that sent the Briton clear at the top of the Formula One world championship for the first time in a year. The triple champion, who started the last race of the European season from a record 69th career pole position, led Finnish team mate Valtteri Bottas to a runaway one-two finish at Ferrari's home track. "I love it here in Italy and I love the passion of the fans," Hamilton declared on the podium jutting out over a sea of red-shirted Ferrari fans, with plenty of boos coming his way amid the cheers. "We did a great job, the team did an exceptional job this weekend," he added. "Mercedes power is definitely better than Ferrari power." Ferrari's Sebastian Vettel, who had led the standings since he won the Australian season-opener in March, finished third in the final race of the European season and 36.3 seconds behind the winner. Bottas was 4.4 adrift of Hamilton. "It was a difficult day, a difficult start," said Vettel. "My race was fairly isolated, we tried to keep as close as possible but we simply didn't have the pace... You could say it's a bad day but I know the team is on the right way... so I am in a very positive mood despite the numbers." Hamilton is now three points clear of the German, with seven races remaining. Mercedes are 62 points clear of Ferrari in the constructors' standings. The first driver to win two races in a row this season, with Monza following on from Belgium a week ago, Hamilton now leads Vettel 6-4 on victories in 2017. He has 238 points to Vettel's 235. The last time Hamilton led the standings on his own was at Monza a year ago, with now-retired team mate Nico Rosberg emerging as the eventual champion. FEW THRILLS Hamilton and four-times champion Vettel were level on points this year after China in April, with one win and one second place each. If Sunday's race was a dull affair, there was at least plenty of sunshine in marked contrast to the steady rain that drenched fans and delayed qualifying for hours on Saturday. Hamilton pulled away cleanly from his historic pole, and fourth in a row at Monza, and was never challenged as he drove to the chequered flag with the minimum of fuss. It was his third Italian Grand Prix win in four years and 59th career victory – only Michael Schumacher, whose pole record he beat, can boast more – and few have been more straightforward.

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.
