Carlsson turns Mercedes-Benz SLK into 610-HP hill-climb clawer

Carlsson's race-tuned versions of the Mercedes-Benz SLK have been taking checkered flags for years, and we won't be surprised if its SLK 340 hill climber fares any different. Developed by multiple German and Swiss hill climb champion Reto Meisel, the carbon-bodied SLK 340 with lightweight brakes and a closed underbody weighs 1,716 pounds. Propelling that tiny bit of weight is a 3.4-liter V8 from Judd with 610 horsepower, and it rolls on 18-inch wheels shod in Avon tires.
It will debut at the Geneva Motor Show before beginning its racing campaigns in the summer. This one won't just tear up roads in Europe, though - Meisel says he plans on bringing it to the Pikes Peak International Hill Climb. The press release below has more details.

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.

Mercedes-Maybach G650 Landaulet is the ultimate safari machine

Update: A Mercedes representative has informed us that the Mercedes-Maybach G650 Landaulet will not be available in the United States. The text has been updated to reflect this. Vehicles such as the Mercedes-Benz G63 AMG 6x6 and G500 4x42 are all well and good, but they have one key issue: They simply aren't extravagant enough. Now we know that sounds insane because one of those vehicles has six driven wheels and the other is available in tennis-ball green. But they must not be decadent enough because Mercedes went a step further with the new Mercedes-Maybach G650 Landaulet. While the most obvious change here is the soft-top, which will make this perfect for the wealthy to view wildlife on private safaris, we should start under the hood. The previous two monster G-Wagens made do with lowly V8s. This one features a twin-turbocharged V12 making 630 horsepower and 738 lb-ft of torque. Like its predecessors, this G650 uses a four-wheel-drive system with front, center, and rear differential locks, and sends power to solid portal axles front and rear. These axles move the differential and drive axles above the wheel centers for additional ground clearance. Inside, the rear passengers will be in the lap of luxury, even while the driver is navigating particularly harsh terrain. The soft top can be electrically raised or lowered, as can a glass partition to the driver's compartment. The two individual rear seats can be fully reclined, and leg rests deploy from below, taking full advantage of the truck's long wheelbase. This would likely make for an amazing vehicle for stargazing. The passengers also have access to folding tables, 10-inch LCD displays, and heated, cooled, and illuminated cup holders. Only 99 of these G650s will be built. Mercedes will show the SUV at this year's Geneva show, and it will hit the market this fall. Mercedes hasn't announced pricing, but expect it to be exorbitant. Not that matters for American buyers, since a Mercedes representative told us it won't be offered in the States. For buyers in countries where the G650 will be available, they will have the option of four interior color schemes, three soft-top colors, and four paint hues. Related Video:
