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.

2014 Mercedes-Benz C63 AMG Edition 507 still lights our fire

The current Mercedes-Benz C63 AMG may be in the autumn of its years, but it's still one of our very favorite sport sedans. Ever. Yes, its paddle-shift transmission may not always follow orders, but with stupendous levels of thrust from its charismatic naturally aspirated 6.2-liter V8, ebullient rear-wheel-drive dynamics and that noise, we frankly don't care that it's getting on a bit.
As a sendoff of sorts for the current generation, Mercedes-Benz has just introduced a new Edition 507 model at the Geneva Motor Show, with 507 horsepower and 450 pound-feet of torque - an increase of 56 horses over the standard car. Mercedes credits the substitution of low-mass internals from the SLS AMG gullwing for the power bump, a tactic shared with the AMG Development Package upgrade that has been subsumed by this Edition 507. 0-60 is quoted at 4.1 seconds and top speed at 174 mph.
The Edition 507 borrows its aluminum hood from the C63 AMG Black Series Coupe, along with spidery new 19-inch wheels in either titanium gray finish or matte black with shiny rim flanges. As seen on our gallery car above, a sports striping package is also featured, as are glossy black grille, daytime running lamps, spoiler and mirror caps.

Infiniti went out of its way to make the QX30 not a Mercedes

You can complain all you want about perceived badge engineering when a company (like Mercedes-Benz) sells a platform to another brand (such as Infiniti). The reality is that most buyers won't know the difference, and they won't even realize their Infiniti is really a Mercedes underneath or that their neighbor's GLA has the same basic parts as the QX30 they just bought. What's weird to me isn't that sameness, but the places where the two cute little utes differ. These two vehicles, which are more like tall hatchbacks, use the same Mercedes 2.0-liter turbo four and seven-speed dual-clutch transmission. Infiniti adds its own throttle and transmission calibrations. The suspension design is the same, although there are tuning differences. Both come standard with front-wheel drive, with all-wheel drive an option. Fuel economy matches for the FWD models, while the AWD Infiniti lags behind the Mercedes for some reason. So they're very similar despite their different looks. And design makes sense as a point of differentiation. Frankly, they go further than a lot of vehicles on shared platforms do – further, in fact, than the upcoming Nissan Navara-based Mercedes X-Class pickup does. The QX30 has its own sheetmetal and glass to separate it from the GLA-class. You probably think one looks better than the other. If you know where to look, the signs of sameness are obvious. Most major systems and pieces are shared, like the steering wheels (with different center covers), most switchgear, and things like interior and exterior door handles. Shared parts are fine as long as the parts are good ones. On that note, how many Tesla buyers realize their steering column and stalks, plus the window switches, come from Mercedes? And does that actually matter? We'd argue no. About those differences. Many are functional, like the fact the Infiniti does not carry over the Benz's Brake Hold feature – when you roll to a stop in the GLA (or any other Benz), pressing the brake pedal firmly applies the electric parking brake until you hit the gas to move again. The QX30 has an electric parking brake, but no Brake Hold feature. Someone used to driving Mercedes models will look a bit silly standing on the brake pedal to no effect. Ask us how we know. The Mercedes gauge package is carried over, but with the Infiniti font. Makes sense, although it's off-putting at first if you've seen the original, prompting a weird deja vu. Circular dash vents are replaced by rhomboid ones.
