Boston bombers were tracked using Mercedes mbrace [w/video]

We now know Tamerlan and Dzhokhar Tsarnaev, the two brothers said to be behind the Boston Marathon bombings, planned to head for New York City to detonate more improvised explosive devices. As it turns out, that plan was foiled by the quick thinking of one Mercedes-Benz owner, diligent police work and the Mercedes-Benz mbrace system. When the brothers carjacked a 26-year-old Chinese entrepreneur identified only as "Danny," they didn't realize his Mercedes-Benz M-Class was equipped with the mbrace system, which can call for help in the event of an accident or track the vehicle in the event of a theft.
According to reports, the Tsarnaev brothers held Danny hostage for nearly 90 minutes while they drove around Boston forming a plan until they had to stop for fuel. When one of the brothers went inside to pay, the other put his gun down for a moment. Danny took the opportunity to unlatch his seat belt, open the door and run to another nearby gas station, where he told the owner to call the police.
When police arrived, they used the mbrace system to track the SUV after receiving Danny's permission, and it wasn't long before a shootout between police and the brothers ensued. When it was over, the eldest brother lay dead in the street. For more on the story, view the video report available below.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.
