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.

2016 German Grand Prix race recap: so-so racing, great questions

We can summarize the 2016 German Grand Prix in one sentence: Mercedes-AMG Petronas driver Lewis Hamilton started second on the grid, passed pole-sitter and teammate Nico Rosberg before the first corner, and dominate to the finish. In fact, Hamilton turned his engine power output down on Lap 3 and still took the checkered flag seven seconds ahead of Red Bull driver Daniel Ricciardo. Ricciardo's teammate Max Verstappen crossed the line another six seconds back. Rosberg fell to fourth at the first corner and couldn't find the pace to reel in the Red Bulls. His questionable pass on Verstappen didn't help when the stewards penalized Rosberg five seconds; the overtake reminded us of Rosberg's move on teammate Hamilton in Austria. That penalty turned into eight seconds when the Mercedes-AMG Petronas stopwatch didn't work in the pits. Ferrari pilots Sebastian Vettel and Kimi Raikkonen finished fifth and sixth. Those six drivers all started in the top six, too. Behind them, on Lap 28 of the 67-lap race the next four drivers were Valtteri Bottas in the Williams, Nico Hulkenberg in the Force India, and Jenson Button and Fernando Alonso in McLarens. Low fuel and old tires put the kibosh on Alonso's pace just four laps from the finish, allowing Force India's Sergio Perez to pass, rounding out the top ten. The issues up for debate during the four-week break are far more interesting than the weekend's race. As bad as Ferrari's day might have been – and we'll get to that – Rosberg probably took the biggest hit, losing the race before the first corner for the second weekend in a row and falling 19 points behind Hamilton. Rosberg won the first four races of the season, then the teammates tripped over one another in Spain. Hamilton's won six of the seven races since Spain, Rosberg's best result in that time is a second-place in Hungary. Hamilton turned his engine down on Lap 3 (!) because he's used his entire season's allotment of five turbochargers and five MGU-Ks. Those early-season gremlins now have him on edge of grid penalties. Unless Hamilton's momentum cools off in August, however, that reliability danger might be the only dent in his armor. Rosberg, who once led the Championship by 43 points, will surely drown in his thoughts – and maybe schnapps – over the summer break. Whatever the Italian word for "meditation" is, there'll be a lot of it at Ferrari during the F1 summer break.

Mercedes-Benz A45 AMG shows up to fight the hottest hatches [w/videos]

Fun coincidence. On the same day that Audi announces the unveiling of its new S3 Sportback at the Geneva Motor Show, Mercedes-Benz steals the spotlight by confirming that the all-new A45 AMG will also receive its official debut early next month. Starting life as the entry-level A-Class hatchback, the A45 AMG gets the full AMG treatment, which includes numerous performance, handling and styling upgrades.
Under the hood sits an AMG-tuned 2.0-liter turbocharged I4 breathing through a sport exhaust system helping the five-door produce 360 horsepower and 332 pound-feet of torque. This engine is paired to a seven-speed AMG dual-clutch transmission and power is sent to the ground using 4Matic all-wheel drive. Mercedes-Benz says that the A45 AMG will be able to accelerate from 0-60 miles per hour in under 4.5 seconds and it will have a top speed of 155 mph; in the land of hot hatches, it doesn't get much hotter than that. For added performance and handling, AMG has retuned the A-Class' suspension and steering systems and equipped The A45 with a three-stage stability control system that is specific to this car.
Surprisingly, the exterior styling of the A-Class was already sporty enough that the new model doesn't receive too many changes to become the A45 AMG. The biggest alterations include black accents to the chin spoiler, rocker panels and mirror caps, black wheels with red-painted brake calipers and rectangular dual exhaust outlets. Inside, it doesn't take a trained eye to spot the differences. The flat-bottomed sport steering wheel and the numerous red accents throughout the cabin (including the seatbelts!) really help to make this AMG interior stand out; front passengers will also get sport bucket seats that appear to be more than supportive enough for even the most spirited driving conditions.
