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.

These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

Recharge Wrap-up: Tesla firmware update videos, Mercedes S500 Plug-In Hybrid

See the Tesla Model S with Firmware 6.0 in action in new videos from Teslarati. The large software update includes improved traffic-based navigation, a calendar function, updated power management, "Location-Based Smart Air Suspension" as well as other improvements. Drivers get more route options to save energy, and more control over how the car saves energy. The car can also remember ride height settings when driving in those same locations again. Additionally, you can start and drive the car without a key, just using the smartphone app. See how it all works in the videos below, the second of which focuses on pairing with the updated phone app. The California Public Utilities Commission (CPUC) has deemed ride-hailing app Uber's carpooling service illegal. The way the UberPool service is categorized by the CPUC, charging multiple riders separate fares for a single ride runs afoul of the law. The technical details are a bit convoluted, and what supporters could deem arbitrary, but Forbes delves into the details a bit further to try to make sense of California's intentions (even considering the possibility of other ride services, such as airport shuttle companies, fueling the fire). Lyft - which operates a similar service called LyftLine - and Sidecar have also received notices from the CPUC. Read more at Forbes. China's recent enthusiasm for electric vehicles could be largely attributed to a single person, Ma Kai. After the Politburo member was named vice premier, he encouraged maintaining and increasing EV subsidies when China sought to decrease them. He also seems ready to fight for more EV deregulation to encourage more clean vehicles. Read more about Ma Kai and what he's done for China's EV legislation at Automotive News. Mercedes-Benz begins deliveries of the S500 Plug-In Hybrid this month. The high-tech luxury PHEV features energy saving modes based on driver, route and traffic, and features a haptic accelerator that can signal when the driver should ease off to save power. It's powered by a biturbocharged V6 and 85-kW electric motor. Its 8.7-kWh battery offers about 20 miles of electric driving. The S500 plug-in starts at about $146,000.
