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.

Editors' Picks April 2021 | Honda Accord, Mercedes-Benz E-Class and more

The month of April saw us award Editors' Picks status to a couple mega-luxury vehicles and a couple long-time standbys that recently went through mid-cycle refreshes. We drove plenty of other cars that didn't quite reach the bar for Editors' Picks status — BMW 4 Series, Infiniti QX55 and the Mitsubishi Outlander among others — but the four you'll see below stood out as the best this month. In case you missed our previous couple Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in April that earned the honor of being an EditorsÂ’ Pick. 2021 Aston Martin DBX 2021 Aston Martin DBX View 16 Photos Quick take: With attractive styling and a gorgeous yet functional interior, the V8-powered DBX is a legitimate crossover worthy of the Aston badge. Score: 8 What it competes with: Bentley Bentayga, Lamborghini Urus, Rolls-Royce Cullinan, Mercedes-Maybach GLS 600 Pros: Mega style, fantastic driving dynamics, a true and faithful Aston Martin Cons: Very expensive, only average infotainment From the editors: Editor-in-Chief Greg Migliore — “The DBX captures the spirit of Aston Martin in a modern crossover. That's not an easy thing to do. I expected the DBX might look the part, but lack functionality. Or it would be a decent crossover, but fall short of my idea of an Aston. The DBX did neither. It exceeded my expectations and is an entertaining vehicle to drive. The styling is interesting and evocative, and the AMG-sourced powertrain delivers proper performance. I also loaded it up with groceries and a carseat fits pretty well. Mission accomplished for Aston." In-depth analysis: 2021 Aston Martin DBX First Drive Review | A crossover that makes you forget itÂ’s a crossover   2021 Bentley Flying Spur 2021 Bentley Flying Spur V8 View 20 Photos Quick take: There are technically competitors to the Flying Spur, but nothing matches it stride-for-stride in every category. ItÂ’s the Bentley flagship product now, and it flies the brandÂ’s flag with both gusto and excellence. You can't go wrong whether you spec the W12 or V8 either.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.
