Mercedes may end Tesla supply agreement for B-Class Electric Drive

The Mercedes-Benz B Class Electric Drive has only been rolling off the production line for 17 months, each one equipped with a battery pack and drivetrain from Tesla Motors, but already there is talk of big upcoming changes. According to a report from the German publication Auto Motor und Sport, the next-generation version of this model will see an end to the Tesla-supplied tech and a hugely improved range. Currently, the electric sedan gets an EPA-rated 87 miles of range, using 28 kWhs of its 36-kWh battery, though its now-standard "Range Plus" package takes advantage of more of the pack, stretching that driving to 100 miles or so. It may take a year or several – the model just had a refresh – but expect those distance digits to double. The rumored range is said to be 500 km (310.7 miles), but since that would likely be calculated using the European drive cycle, expect something significantly lower stateside; say 220-ish official miles. This would be in keeping with expectations from a number of battery-powered competitors in the 2017-2018 time frame. It is unknown if this supposed next-gen B Class Electric Drive is in any way related to the rumored "Ecoluxe" program. The Tesla/Daimler relationship stretches back to 2009, when the Stuttgart-based outfit made a significant investment in the California automaker, quite possibly saving it from extinction in the process. We have reached out Mercedes-Benz about this report, but as of this writing, have not had a reply. We will update this post when we hear back.

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.

Daimler opens the door on Car2go Black with B-Class carsharing

Mercedes-Benz parent Daimler has finally decided to go to its proverbial mothership to further expand its Car2go carsharing service in Europe. The German automaker has long used its itty-bitty Smart Fortwo vehicles for the program, but now it's kicking off a pilot program called Car2go Black that will share Mercedes-Benz B-Class models in Berlin and Hamburg. Daimler will deploy 100 B-Class diesels in each German city. The company says the cars will be parked at so-called "black" parking spots and won't have to be returned to the same spot when the user is done. Daimler, who says the reservation platform is geared for smartphone use, is planning to expand the program to other European cities with existing Car2go service starting this spring. That's important, since once the system is up an running, you will be able to drive a Car2go Black vehicle from one town in the network to another and not need to bring it back. Car2go first started operations in Ulm, Germany, and made its North American debut in Austin, TX, in 2009. The service now has more than 600,000 members worldwide with access to about 10,000 Fortwos in 25 cities throughout Europe and North America. Car2go chief marketing officer J. Paul DeLong said last month that Car2go is the world's largest global carsharing company.
