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.

Weekly Recap: An '80s encore in the auto world

The '80s returned in a big way this week, as National Lampoon's, Ghostbusters, Miami Vice, and even Tetris were back in the news. While there were far more serious topics (see below), nostalgia mingled with modern marketing to put these Reagan-era favorites back in the spotlight. The '80s were alternately cold and corny at times, but their cultural touchstones can still generate big money. That's why Infiniti recreated an iconic scene from National Lampoon's Vacation (1983) for an advertisement that hawks the QX60 crossover. Actor Ethan Embry, who played Rusty Griswold in a later Lampoon's movie, pilots the Infiniti – which is serving as a modern Family Truckster – for a trip to Walley World. A blonde pulls alongside in a red Lamborghini. They flirt, and she drives on. Christie Brinkley, who played the original girl in the red sports car (she drove a Ferrari in the '83 flick), is riding shotgun and chides Embry with: "A blonde. In a convertible. Seriously?" Okay, it's hardly on the level of "here's looking at you," or even "you can't handle the truth," but it should resonate with '80s babies, many of whom are now having children of their own and moving into three-row SUVs like the QX60. Naturally, Hollywood is going back to the well, too, with a Vacation remake that premiers July 29. Meanwhile, Ghostbusters is returning next year, and director Paul Feig offered a peak at the new Eco-1 in this tweet. In the 1984 classic, the team drove a modified 1959 Cadillac. Now, it will drive a late '80s Cadillac. As expected, the announcement generated support and controversy from movie and car enthusiasts. His tweet had generated several thousand retweets and favorites in the days following the news. Though the '80s Caddy looks, uh, less elegant in comparison to the now-iconic fins and curves of the original Ecto-1, it's about the same time lapse into the past as the '59 Caddy was to viewers in 1984. Speaking of 1984, Miami Vice, which debuted that year on NBC, is seeing one of its hero cars hit the auction block, Mecum Auctions announced this week. The 1986 Ferrari used on the show will be offered for sale Aug. 15 during Monterey classic car week. The white supercar runs a 390-hp flat 12-cylinder engine paired with a five-speed manual transmission and was in storage after the show ended in 1989 until earlier this year. It has 16,124 miles on the odometer and is authenticated by Ferrari North America and Classiche.

Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.
