2015 Chinese Grand Prix shines bright sun on the dark days of racing

Yes, we tuned into the Formula One Grand Prix in Shanghai China to see a race. But we all know we really tuned in to see if Ferrari, or any other team, could make it a competitive race with Mercedes-AMG Petronas. Based on qualifying, things didn't get off the best of starts: Lewis Hamilton made it four-out-of-four at the front, leading all three Free Practice sessions and then taking pole position in his Mercedes. Nico Rosberg is making the most of his time in the simulator, getting closer to Hamilton as the months go by. This time he lined up in second, just 0.042 in arrears. Ferrari did its best to temper expectations after Malaysia. Even though Sebastian Vettel qualified in third, almost a second behind Hamilton, the Scuderia's race pace is still considered a danger. Kimi Raikkonen's final hot lap went sour in Turn 3 and dropped the Finn to sixth place on the grid. In between the Ferraris, Williams is another team desperately working to maintain its advantage, and both of its drivers capitalized on Raikkonen's misfortune. Felipe Massa took fourth, Valtteri Bottas was in fifth. Daniel Ricciardo led the Infiniti Red Bull Racing charge in seventh, ahead of Romain Grosjean in the Lotus earning a spirits-lifting eighth. The two Saubers continue to show how good the Ferrari engine is, with Felipe Nasr taking ninth position and teammate Marcus Ericsson in tenth. Yet when the lights went out, so did the racing, for the most part. At the end of the first lap, because of some excellent moves by Raikkonen on both Williams' and a terrible start by Ricciardo that dropped him to seventeenth, the order was Hamilton, Rosberg, Vettel, Raikkonen, Massa, Bottas, Grosjean, Nasr, Ericsson, and Pastor Maldonado in the Lotus rounding out the top ten. At the end of the race, the only positions that had changed were the final two: Ricciardo had a laps-long battle with Ericsson, passing, getting repassed, then passing again to take ninth for good, with Ericsson finishing tenth. Maldonado suffered the worst in a battle with Jenson Button in the McLaren, when Button misjudged the entry into Turn 1 for a pass and clouted the back of the Lotus. Button was able to finish but Maldonado had to retire. Yes, there were some decent moments in between, like Bottas getting by Massa at the start, then Raikkonen getting past Massa in the first few corners and the Finn's move on Bottas also letting Massa through.

Lewis Hamilton has Vettel in crosshairs at Canadian Grand Prix

MONTREAL - The Canadian Grand Prix has been a happy hunting ground for Lewis Hamilton, and he will look to bag a sixth career win on the island circuit on Sunday to refuel his hopes of another Formula One drivers title. With 14 races remaining on the calendar, it is far from do-or-die for Hamilton, but the pressure is mounting on the Briton and Mercedes with arch rival Sebastian Vettel and Ferrari threatening to widen the gap at the top of the championship standings. Only Michael Schumacher has won the Canadian Grand Prix more times (seven), and Hamilton intends to close the gap further in Montreal as the race marks its 50th anniversary. Hamilton needs to do so, at the scene of his first ever Formula One victory a decade ago, to reel in Vettel after the German led a Ferrari one-two in Monaco and powered 25 points clear. "Montreal has been a great hunting ground for me in the past, and I plan for it to continue," the triple world champion told reporters. With five wins and five poles from previous visits to Quebec, Hamilton would normally be the favorite, but champions Mercedes are no longer the dominant team. "The Ferrari seems to work everywhere. The next 14 races are going to be very, very difficult," he said after struggling to seventh place in Monaco. "They have had arguably the strongest car all year. They look like our car which just worked everywhere last year." The race will also mark the return of twice world champion Fernando Alonso to the Formula One grid after the Spaniard skipped the Monaco Grand Prix last month to chase IndyCar glory at Indianapolis 500. Alonso turned in an impressive performance at the famed Brickyard, qualifying fifth fastest and running at the front but late in the race suffered a familiar fate with his Honda engine giving up. Little has changed at struggling McLaren during Alonso's brief sabbatical with the team still hampered by an uncompetitive Honda engine. There is plenty of reason to party around the Circuit Gilles Villeneuve this week with the city celebrating its 375th anniversary, Canada its 150th birthday and the Canadian Grand Prix its 50th. Williams driver Lance Stroll will be hoping to contribute to the party atmosphere. For the first time since the days of 1997 world champion Jacques Villeneuve, the Canadian Grand Prix will have some true home interest with teenager Stroll on the starting grid for Williams.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.
