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.

Audi RS3 Sedan coming to America with over 400 hp?

The Mercedes-Benz CLA45 AMG is a fast, competent car. It's significantly sharper than the Audi S3, and it should be, since its starting price is around $7,000 more. Still, getting walloped by the higher-performing CLA45 AMG must irk some people at Audi, we'd think, which might explain why there are rumors that the S3's big brother is coming to town. Yes, reports are popping up from an Audi of America employee that the Audi RS3 would transition from its Euro-market Sportback body style to a more conventional four-door, and that its styling would be updated in the process. Oh, and it'll have a 400-plus-horsepower, 2.5-liter, five-cylinder turbo with which to bash the four-cylinder AMG. The report comes from Quattro World by way of CarScoops, and goes on to claim that Audi hallmarks like Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission will both be present. The new RS3 Sedan would arrive on US shores in 2017 as a 2018 model, with prices starting between $55,000 and $60,000. That should make Mercedes-AMG very nervous – the CLA45 may start around $50,000, but getting it past the $60,000-range is simple (your author was driving a nearly $68,000 CLA45 just last month, for example). Naturally, we have a call in with Audi of America to see if there's any credence to this report. Stay tuned for updates. Related Video:

2016 Formula 1 Chinese Grand Prix recap: another wild show on and off track

Normally we use this space to provide a lengthy recap of the weekend's Formula 1 race, but we're going to try something different since most folks reading this know what happened at the Shanghai International Circuit on Sunday. Instead, we'll alight on what we saw as the big issues in and around the race. Let us know what you think in Comments. Proper qualifying is back. Thank goodness. It only took a month of embarrassment to fix it. And so is passing! For the third race in a row, big performance improvements at the ten teams behind Mercedes-AMG Petronas and a wider tire selection at this race graced us with opening stints filled with dicing cars. Seeing the McLarens on screen doesn't make us cringe. Manor doesn't only make the global feed when it's being lapped. We've been complaining about parade races for so long that we forgot excitement was possible without rain or wholesale regulation changes. Yes, Mercedes is still the king of the jungle, but there are some other proper midfield beasts on the hunt, too. Malfunctions up and down the grid did help the show in Shanghai, like Lewis Hamilton suffering perpetual troubles, Nico Hulkenberg's runaway front wheel which red-flagged Q2, and Sebastian Vettel's and Kimi Raikkonen's flubbed hot laps in Q3 that let Daniel Ricciardo slip by into second on the grid. Come race day things went all Grand Theft Auto at Turn 1 on the opening lap, sending some of the best cars to the pits. Then came Ricciardo's puncture while leading, then came the Safety Car – all by Lap 5. Nico Rosberg got 38 seconds of airtime on the way to victory – at the start and the finish, and that happened to be his margin of victory, too – otherwise he was a ghost. Everyone else was struggling and juggling. Rosberg's win at the Bahrain Grand Prix put the German at five consecutive victories going back to last year's Mexican Grand Prix. The history books show that any driver who's won five straight contests has gone on to win the championship. With his triumph in China, the German has won the season's first three races, the history books again show that the other nine drivers who've pulled that off have gone on to win the championship. Rosberg, 36 points ahead of his teammate in the standings, is having none of it. He said of the other victors, "But they didn't have Lewis Hamilton as their team-mate." Perhaps Mercedes was right not to make an engine deal with Red Bull last season.
