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.

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.

Recharge Wrap-up: KillaJoule hits 270 mph; Mercedes B-Class ED gets PlugShare

The Mercedes-Benz B-Class Electric Drive will get its own version of the PlugShare charging-station locator app. Developed by Recargo with the help of Daimler, the vehicle-specific app will be integrated into the car's navigation system. The system maps the location of nearby charging stations from various networks. So far, Mercedes-Benz doesn't offer a universal pay service for the various charging networks, like those offered by BMW and Nissan. Read more at Green Car Reports. HyperSolar uses solar energy to make hydrogen from water. Without using electrolyzers, HyperSolar uses a photochemical process to separate and capture the hydrogen in the water, which can then be used for clean energy, such as automotive fuel cells. The solar devices are submerged in water inside a container, and sunlight powers the device to free the hydrogen. HyperSolar claims that its process is more efficient and cost effective than other methods used to produce hydrogen from water. See some demonstrations in the videos below and learn more at HyperSolar's website. Eva Hakansson drove the KillaJoule electric motorcycle to a top speed of 270.224 miles per hour. After a computer model showed a possibility of about 270 mph, the team took the motorcycle with sidecar out to the salt flats for Mike Cook's Shootout. Everything went smoothly, and Hakansson easily surpassed speeds of the 249.1-mph world record she set a few weeks ago. The team is calling it quits for the season, but will make some tweaks to the KillaJoule in hopes of getting 300 mph out of the red bullet next year.
