Brabus to storm Geneva with 800-hp version of Mercedes SL65 AMG

At no point during our recent drive of the 2013 Mercedes-Benz SL65 AMG did we ever think, "You know, this thing sure is slow." After all, Merc's range-topping SL comes fitted with a twin-turbocharged 6.0-liter V12 capable of sending 621 horsepower and 738 pound-feet of torque to the rear wheels. But just in case you're still all "meh" about what the SL65 throws down, Brabus will gladly come to your rescue with this, the 800 Roadster.
As its name suggests, the 800 Roadster ups the V12's power figures to 800 horsepower and - wait for it - 1,047 pound-feet of torque. Don't get too excited, though - that torque number has been electronically limited to a measly 811 lb-ft since, you know, the transmission would probably explode if you tried to put the full force through it. Nevertheless, these represent increases of 79 hp and 73 lb-ft over the standard SL65, and that means the 800 Roadster can shoot to 62 miles per hour in just 3.7 seconds - two-tenths of a second quicker than the Merc its based on. More impressively, hitting 124 mph takes just under 10 seconds, and the droptop will finally top out at an electronically limited - limited! - 217 mph. Holy smokes.
To manage all of that speed, Brabus has engineered a special carbon fiber aero kit that reduces lift, and a unique control module for the SL65's active body control suspension lowers the ride height by one full inch. The 800 Roadster rides on new 20-inch wheels, and a unique limited-slip rear differential was added, featuring a 40 percent locking rate that further enhances performance when you're attempting to control the beast at its limits. Interior upgrades include new leather and alcantara surfaces throughout the cabin, including a leather-clad trunk.

2013 Mercedes-Benz SLS AMG GT Coupe

Mercedes-Benz upgraded its SLS flagship Coupe and Roadster for the 2013 model year, and the changes are marked with them new "GT" nomenclature. Both SLS models arrive with a retuned naturally aspired 6.2-liter V8 delivering 583 horsepower and 479 pound-feet of torque (the horses are up from 563, but the torque remains the same) mated to a revised seven-speed AMG Speedshift dual-clutch gearbox. Rounding out the mechanical upgrades is a redeveloped AMG two-mode adaptive suspension. Physically, the revised models are differentiated by their new "GT" badging, darkened headlight/taillight buckets, red brake calipers, unique wheel colors and high gloss finish on the front grille, exterior mirrors and hood/fender fins. Inside the cabin are new red seatbelts, Alcantara upholstery and contrasting red stitching.
As it is nearly impossible to experience the aluminum gullwing beast on public roads, Mercedes invited out to Southern California's Willow Springs to wring out the 2013 SLS GT Coupe on a racing circuit.

Mercedes-AMG GT R coming with active aero, shocks, steering

We've seen the Mercedes-AMG GT, and we've seen the Mercedes-AMG GT S. So what comes next? According to Motor Trend, the Mercedes-AMG GT R, that's what. Word has it that the forthcoming addition AMG's flagship sports car range will wear a similar name to Godzilla. Of course, Nissan might have a thing or two to say about that, but considering that, as it is, the letters GTS are also used on by BMW and Porsche (to say nothing of the Dodge Viper), Daimler might still find itself in the clear. Naming schemes aside, the upcoming top-of-the-line AMG GT is naturally expected to pack more power than existing versions. But it's also tipped to get a four-wheel steering system to improve cornering and high-speed stability, similar to those featured on the Porsche 911 GT3 and Ferrari F12 TdF. A new type of adjustable spool-valve shocks are also said to be in the works, along with active aerodynamic elements. Expect upgraded rolling stock, brakes, and interior to come as part of the package when it debuts in about a year from now. MT also reports that AMG is also already working on a new E63 based on the forthcoming W213-generation E-Class. The new super-sedan is expected to shed weight by replacing the old 5.5-liter twin-turbo V8 with the newer, more compact 4.0. It's also tipped to get a new nine-speed dual-clutch transmission and a more flexible all-wheel-drive system to replace the fixed 33/67 front-rear torque split on the current model.
