Geneva 2011: RUF Presents 730HP and 370+km/h Rt 12 R based on the Porsche 911 Turbo [with Video]

The 2011 Geneva International Motorshow plays host to the world premiere of the RUF Rt 12 R. The latest supercar from the Porsche tuning specialist is based on the 911 Turbo having received a bevy of modifications including a engine kit that pushes the output of the 3.8-liter twin-turbocharged flat six from 500HP and 650Nm (700Nm with the overboost function) to 730HP and 940Nm (693.3 lb-ft) of peak torque for a top speed in excess of 370km/h (230+ mph). A six-speed manual gearbox transfers power to the all-wheel drive system

Other upgrades include ceramic brakes, 19-inch forged alloy wheels wrapped in 245/35 tires at the front and 325/30 at the back, an aero kit and an adjustable suspension. RUF also reduced the weight of the 911 Turbo through the use of exotic materials such as the carbon fiber wings, front luggage cover and bucker seats. The price of the Rt 12 R is set at €279,000 or about US$386,400 at today's exchange rates.

Geneva 2011: Brabus 700 Biturbo is One Mean Mercedes-Benz SLS AMG

The Mercedes-Benz SLS AMG is the car most tuners wanted to put their mark on at this year's Geneva Motor Show. Brabus of course, couldn't miss out on this party, so here's what they came up with: a 700 horsepower wide-body version of an already impressive supercar.

Called the 700 Biturbo, Brabus' iteration of the SLS AMG received the Widestar treatment, which means the car is 20 millimeters (0.8 in.) wider at the back, creating the necessary space for the extra wide 11Jx21 wheels (9.5Jx20 on the front).

Brabus says the entire body was subjected to aerodynamic tunnel tests to ensure the car is stable at high speeds. The front spoiler, the covers for the air inlets, the gills, the rear spoiler and the diffuser are all made from carbon-fiber and contrast the silver paint of the 700 Biturbo. Brabus also added carbon side skirts fitted with air vents for the rear brakes.

Inside, the German supercar can be fitted with matte or shiny carbon-fiber elements of any color, matte anodized aluminium pedals and foot rests, as well as an ergonomically shaped sport steering wheel. The speedometer dial shows a maximum speed of 400 km/h (250 mph), even though 700 BiTurbo goes up to 340 km/h (213 mph).

It's still 23 km/h (14 mph) faster that the production model, and it gets from 0 to 100 km/h 0.1 seconds quicker, at 3.7 seconds. These figures are made possible thanks to the fitting of a twin-turbocharger to the V8 engine which helps unleash an output of 700 horsepower and 850 Nm of peak torque (626 lb-ft) at 4,300 rpm. Mated to the SPEEDSHIFT DCT seven-speed transmission, the 700 Biturbo can reach 200 km/h (124 mph) from a standing start in 10.2 seconds.

Developed by Brabus, the engine conversion also includes a large intercooler, high-performance air filters, new mapping and specially manufactured forged pistons.

Other changes include a new titanium exhaust system and a new suspension that lowers ride height by up to 30 millimeters (1.2 in.) and has a “Ride Control” function, altering the damping according to needs.
