2015 Bahrain F1 Grand Prix puts a dark horse in the desert [spoilers]

Ferrari's Kimi Raikkonen had said after Malaysia that Ferrari can challenge Mercedes-AMG Petronas purely on pace, beyond the scope of tire wear, in the dry. We didn't see that in China, where Lewis Hamilton easily kept everyone behind and Ferrari's Sebastian Vettel only got close to Mercedes' Nico Rosberg when Rosberg slowed down to conserve his tires. But the Iceman's words seemed prescient during qualifying for the Bahrain Formula One Grand Prix. At the front, nothing has changed so far this year: four races, four pole positions for Lewis Hamilton. Instead of teammate Rosberg next to him, though, he'll look over to see the scarlet Ferrari of Vettel, who took advantage of Rosberg's cautiousness to snatch second place on the grid. In Q2, Rosberg tried to conserve the tires he'd start the race on and said he couldn't get into a groove in Q3, putting in a time 0.147 seconds slower than Vettel. The second Silver Arrows will share his row with the second Ferrari, Raikkonen – yet again – saying he might have left some time on the table during his hot lap but getting around just one tenth off Rosberg's time. Williams is established as the best of the rest behind two teams this year instead of just one last year, Valtteri Bottas claiming fifth ahead of Felipe Massa. Daniel Ricciardo of Infiniti Red Bull Racing said he wants to fight with the Williams', he'll be helped with a good start off the line for the first time this year. Nico Hulkenberg got Force India into Q3 for the first time since the Italian Grand Prix last year and into eighth on the grid, ahead of Carlos Sainz in the Toro Rosso and Romain Grosjean putting in another excellent day's work for Lotus. Come race time, it turned into Mercedes power against Ferrari strategy. When Sky F1 commentator Martin Brundle talks about the Mercedes-AMG Petronas team he often mentions how their engine advantage leads to other advantages throughout the car. Not having to use aerodynamic changes to make up for power unit deficiencies, for instance, means they can run the aero setup they want, which optimizes speed and tire wear throughout a lap. It equates to advantage on top of advantage on top of advantage. That's where Lewis Hamilton is right now, so fundamentally dialed in to his car and his racing that he run the races he wants to run. From the front spot, the Brit ripped off another perfect start and led the field into Turn 1, relinquishing the lead only during pit stops.

2015 Austrian F1 Grand Prix switches to alternating current

It's called the Red Bull Ring, guests are welcomed by a statue of a leaping bull, and dominating its layout demands powerful cars that can run it hard. Perhaps all that aggression is what led both Mercedes-AMG Petronas cars to run off the track in the final qualifying session on their final hot laps, a little too aggressive on the charge. Lewis Hamilton was first into the gravel at Turn 1 when he lost his car under braking, but he was still fast enough to get pole ahead of teammate Nico Rosberg, who spun at Turn 8. Rosberg started second. Or perhaps it wasn't the red bull but the scarlet horse that caused The Silver Arrows to muck it up: Ferrari driver Sebastian Vettel had Mercedes' attention all weekend, and he'd line up in third just 0.355 off Hamilton's time. Williams truly rediscovered its power, Felipe Massa going fourth fastest, teammate Valtteri Bottas in sixth. Between them was newly-minted Le Mans winner Nico Hulkenberg, yet again – can we say that enough? – pulling the still-not-updated Force India to fifth place on the grid. Max Verstappen led the Renault-powered top-ten duo in his Toro Rosso in seventh, Infiniti Red Bull Racing driver Daniil Kvyat behind him in eighth. Kvyat, however, would start down the order because of a ten-place grid penalty for needing a fifth Renault engine. After that it's back to Mercedes Ferrari power, Felipe Nasr in the Sauber in ninth, Romain Grosjean in with Mercedes power in the Lotus in tenth – but fellow Lotus driver Pastor Maldonado actually started in tenth because of Kvyat's demotion. Before we get to the race, can we take a moment to talk about the shenanigans and gaudy penalties? Kimi Raikkonen waved the Ferrari flag in Canada after a season that's been full of "We didn't get it right this time," and we thought he was back. But no. In Austria the refrain returned, the Finn kicked out of Q1 after another miscommunication with the team – he qualified 18th. If the scenario plays to form, we'll now wait for team boss Mauricio Arrivabene to issue a clarification that suggests Raikkonen missed a step. Daniel Ricciardo parachutes ten spots back for the same reason as his teammate Kvyat, needing a fifth Renault power unit, dropping him to 18th on the grid and forcing him into a five-second time penalty when he comes in to pit.

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.
