2014 Mercedes-Benz B-Class ED has 87-mile range, 84 MPGe

Well, that extra weight had to be felt somewhere. With Mercedes-Benz getting ready to start US sales of its B-Class Electric drive this summer, the big question was how well its range would stack up against other electric vehicles sold in the States. Turns out, the Benz is a bit of a juice hog. Let's say up front that the 87-mile single-charge range of the Mercedes-Benz actually stacks up nicely against its competition, since that distance puts the new model right in line with the Nissan Leaf and BMW i3 (we'll ignore the Tesla Model S for a second, here). You can find the numbers at the US Department of Energy's FuelEconomy website. As far as miles per gallon equivalent ratings, though, the Benz's steel frame makes it come up short, as it's about 1,300 pounds heavier than the carbon-fiber-body i3 and about 600 pounds heavier than the Leaf. The B-Class EV has a bigger battery than the i3 or the Leaf (36 kWh compared to 22 kWh for the i3 and 24 kWh for the Leaf) and that's one reason the car gets an 84 MPGe rating, which is about 26 percent less than the Leaf's and 32 percent less than the i3's. But at least the local utility companies will be happy. Mercedes-Benz priced the 177-horsepower B-Class ED in April at $41,450, or $100 more than the i3.

2016 Japanese Grand Prix | Hamilton faces the beginning of the end

We're told the Japanese mamushi viper haunts the undergrowth around Suzuka. If the pit viper attended the weekend's Japanese Grand Prix, it avoided human visitors but it put a nasty bite on Lewis Hamilton's championship hopes. The Briton, lined up second on the grid next to Mercedes-AMG Petronas teammate Nico Rosberg, flubbed his start. By the end of Turn 1 Hamilton was in eighth. Hamilton didn't suffer alone. The beginning of the race was a melee; many of the leaders got caught out either by the damp track or by having to swerve around slow starters. Only Mercedes' Nico Rosberg and Red Bull's Max Verstappen took off clean. The German rolled up another lights-to-flag victory despite the pass-happy race happening behind him. Rosberg was as unbothered by the Dutchman in second place as he was by the official Formula 1 camera feed. Verstappen didn't have much work to do until the final ten laps of the race. Thanks to the Mercedes team's strategy – or Ferrari waiting too long to pit – Hamilton got up to third on Lap 36 of 53. Unable to make a DRS-enabled pass on Verstappen down the front straight toward the end of the race, the Mercedes driver took a creative line through Spoon corner. Closing in down the back straight, Hamilton jinked inside to try a pass through the final chicane. Verstappen moved over in the braking zone while Hamilton was still behind him, closing the door on the move. Hamilton protested over his team radio, but seemed resigned to a third place finish after the incident – he didn't try any more passes in the final laps. The Ferrari duo of Sebastian Vettel and Kimi Raikkonen crossed the line fourth and fifth, respectively, in recovery drives after penalties. The scuderia tried an aggressive final stint after Hamilton successfully undercut Vettel in the pits. Ferrari put Vettel on the soft-compound Pirellis so he could hunt the Mercedes, but after a few laps of close pursuit the tires gave up and Vettel fell back. Daniel Ricciardo couldn't get comfortable in his Red Bull the entire weekend. The Aussie finished where he started, in sixth place. Sergio Perez and Nico Hulkenberg followed the Red Bull home in two-up formation for Force India, Williams doing the same in the final two points-paying positions with Felipe Massa and Valtteri Bottas. Rosberg's 23rd career victory – his ninth of the season and first ever in Japan – puts him 33 points ahead of Hamilton in the Driver's Championship with four races left.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.
