Recharge Wrap-up: Mercedes-Benz B-Class Electric Drive goes on sale in Europe, Spain gets Nissan Leaf taxis

The new Mercedes-Benz B-Class Electric Drive goes on sale in Europe on November 3, with deliveries starting before the end of the year. Developed with the help of Tesla, the new electric B-Class offers more than 132 kilowatts (177 horsepower) and 250 pound-feet of torque. It features Economy Plus, Economy and Sport driving modes. An optional radar support system uses the collision prevention assist sensors to help make smarter decisions about when and how to use the regenerative braking. The B-Class Electric Drive also offers an optional Range Plus button, which can unlock more battery capacity when charging for the occasional longer drive. Learn more in the press release below. Racing returns to the streets of Miami for the first time in more than a decade for the Formula E Miami ePrix on March 14, 2015. Formula E has revealed the track layout, which takes the race around the Miami Heat's home court, American Airlines Arena, along the Biscayne Bay. "This event will help to make Miami more of a sports city," says Mayor Thomas Regalado. "In addition, we will show the younger generations that you may have motor racing without noise or pollution." Read more about the event at the Formula E website and see the track layout in detail here. Hyundai has delivered the first ix35 Fuel Cell vehicles to customers in the UK, including clean energy company ITM Power. ITM is responsible for three of the hydrogen refueling stations being built around the EU as part of the Hydrogen For Innovative Vehicles project - the same project that helped bring the Hyundai ix35 (also known as the Tucson) Fuel Cell to Europe. ITM's 700-bar hydrogen stations will be built in London by Spring 2015, each with its own electrolyzer system on site. In the meantime, ITM will use the ix35 for commutes between London and Sheffield, refueling at a site that uses wind-generated electricity from an on-site turbine to power the electrolyzer to make the hydrogen.

Aluminum supplier Novelis says demand will likely increase 30 percent annually for the next 10 years in China, Japan and Korea, and possibly more depending on how China's plan to increase EV use and decrease air pollution shakes out.

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.

Mercedes-Benz releases US-spec 2014 Sprinter details

Last week, Mercedes-Benz released the details for the updated 2013 Sprinter intended for global markets, but this week it has announced what changes are being made to the US-spec version of the van for the 2014 model year, including the Freightliner model. As expected, most of the changes made to the European model will be present on the 2014 Mercedes-Benz Sprinter when it goes on sale in the US, which is expected to be this fall.
The biggest difference between the Sprinter announced last week and the one headed to our shores is what is found under the hood. While European Sprinters will come with diesel engines and offer the availability of a supercharged four-cylinder gasoline or CNG engine, US Sprinters will still offer the 3.0-liter V6 BlueTEC diesel. This year's Sprinter now comes standard with a new base engine, the 2.1-liter four-cylinder BlueTEC diesel. This smaller engine will produce 161 horsepower and 265 pound-feet of torque, and will be paired to a seven-speed automatic transmission; the optional 3.0 V6 puts out 188 hp and 325 lb-ft of torque, and will be mated to a six-speed auto.
Fuel economy for the new Sprinter has not been announced, but Mercedes-Benz has made numerous changes with the goal of improving efficiency. To this end you'll find a new, low-friction rear axle and the optimization for the generator, fuel pump and power steering pump.
