Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

Mercedes-Benz Concept GLA gets official ahead of Shanghai

Mercedes-Benz has something special planned for the Shanghai Motor Show - a new CUV concept that we first saw when it leaked on the internet yesterday. The GLA Concept compact crossover will hit the show stand with a turbocharged 2.0-liter four-cylinder engine producing 208 horsepower and 258 pound-feet of torque mated to a seven-speed dual clutch transmission and 4Matic all-wheel drive, and likely previews a new production model that we've already spotted testing.
That's not news, but the laser-based headlamps with video-projecting capability certainly are. Mercedes-Benz says the array can project any image or video onto a screen, which is handy since there are a pair of HD cameras mounted to the roof rack. The cameras can be removed and taken with you on all sorts of adventures. The lamps also feature a visible cooling system comprised of a series of fans, and the system helps give the headlights their "sparkle" effect.
Step indoors and the GLA offers up the interior of a high-quality crossover, complete with contrasting leather and plenty of aluminum. The automaker says the cabin was inspired by saddle craftsmanship with "more than 65 feet of hand-stitched seams to hold the raw edges of the leather together."

Mercedes-Benz introduces new heavy security M-Class Guard model

Mercedes-Benz has unveiled a new addition to the company's line of personal security vehicles. The M-Class Guard features bullet-proof side windows made with special laminated glazing and a polycarbonate inner layer to protect occupants from shards of glass. Mercedes says the M-Class Guard meets protection level VR4 according to the Bullet Resistant Vehicles 2009 standards, based on testing from the independent Ulm-based Ballistics Bureau, which means it can withstand .357 Magnum and .44 fire from multiple angles. It can also stand up to the DM51 hand grenade when equipped with optional floor armoring. Why skimp?
Buyers looking for protection from the world's literal slings and arrows can opt for the ML350 BlueTEC with its 258 horsepower 3.0-liter turbodiesel engine. With 457 pound-feet of torque, the oil-burner should have no trouble hustling the privileged class about. Of course, the ML500 offers a bit more punch courtesy of a 4.6-liter twin-turbo V8 with 408 horsepower and 442 pound-feet of torque. Prices start at 105,050 euros for the diesel and 118,650 euros for the V8. You can check out the full press release below for more information.
