IAA 2011: New Mercedes-Benz C63 AMG Coupé Black Series with Aero and Track Packages

Mercedes C AMG

We first gave you a taste of the new C63 AMG Coupe Black Series fitted with the special track and aerodynamic packages back in August when we spied a prototype testing at the Nürburgring, but Mercedes-Benz showed the production model at this week's Frankfurt Auto Show.

Available as separate options on the limited edition C63 AMG Coupe Black Series, which is powered by a 6.2-liter V8 pushing out 517-horses, the AMG Track and Aerodynamic Packages were designed to further enhance the two-door model's driving dynamics.

The Track package adds 255/35 R 19 front and 285/30 R 19 rear sports tires from Dunlop with or without matt black alloys wheels, and an ative rear-axle transmission cooling that is said to improves performance in harsh race-track conditions.

The AMG Aerodynamics package comprises of carbon fibre front flics located on the front apron, carbon fibre front lip spoiler and a fixed carbon-fibre rear wing with an adjustable blade, all of which are designed to increase the lift at the front and rear axles.

Buyers willing to dig deeper into their bank accounts can further enhance the coupe with numerous carbon fibre bits such as exterior mirror housings, inserts on the side sill panel, diffuser insert, spoiler lip, and interior trim parts, plus a keyless-go system, Intelligent Light System ILS, a fire extinguisher and tinted side and rear windows.

IAA 2011: Eterniti Hemera Brings a Breath of Fresh Air to the Porsche Cayenne

Eterniti Hemera

Making its world premiere in close-to-production form is the Eterniti Hemera, which the newly formed London-based company refers to as the "world's first Super-SUV".

A close look at the Hemera reveals that the vehicle is more or less a heavily modified (or tuned, take your pick) Porsche Cayenne SUV, which itself is based on the VW Touareg.

Eterniti claims that all body panels on the Hemera are new and made of carbon composite materials, while the company added that is also working on bespoke LED headlamps and lenses that will make it on the final production model.

Furthermore, Eterniti said that the interior, which is in the final stages of prototype testing and will be revealed later in the year, will be "almost 100% unique" to the SUV model.

Aside from the re-packaged interior, and the lightweight carbon-composite skin, the Hemera will also receive a modified 4.8-litre twin-turbocharged V8 engine producing over 620bhp for a top speed in excess of 180mph or 290km/h.

The Hemera will be hand-assembled at a new factory in London. Production is set to start in early 2012, with first deliveries expected by the summer of the same year.

Eterniti said that while prices have yet to be confirmed, the Hemera will carry a base price tag of around £150,000, or approximately US$237,000 / €174,000 at the current exchange rates.

IAA 2011: Brabus Presents the World's New Fastest Street-Legal Sedan, the CLS-Based Rocket 800

Brabus Rocket 800

Mercedes-Benz specialist Brabus has a thing about building insanely fast cars. Now, half a decade after the presentation of what was then billed as the fastest saloon in the world, the limited run Brabus Rocket based on the first generation of the Mercedes-Benz CLS, the German company returns to Frankfurt with a vengeance presenting a new ludicrous proposal. The successor to the original Rocket is built around the second generation of the CLS sports saloon with power coming from a heavily modified Mercedes-Benz-sourced V12 bi-turbocharged engine.

The German firm's engineers increased the displacement from 5.5-liters to 6.3-liters and made a host of other upgrades including, but not limited to, a reworked intake, newly configured on-board electronics system and redesigned high-performance turbochargers.

As a result, output is lifted to 800-horses at 5,500 rpm and an enormous peak torque of 1,420Nm (1,047 lb-ft), available from just 2,100 rpm, but limited electronically in the car to 1,100 Nm (811 lb-ft).

A modified seven-speed quick-shift automatic transmission with steering wheel paddles along with a limited slip differential handle the transfer of power to the rear wheels.

Brabus says that the Rocket 800 can reach speeds in excess of 370 km/h (230 mph), making it the world’s fastest street-legal sedan.

And if that's not enough to impress you, the Rocket 800 goes from zero to 100 km/h (62 mph) in 3.7 seconds, to 200 km/h (124 mph) in 9.8 seconds and 300 km/h (186 mph) in 23.8 seconds!

The German company also extensively modified the car's aerodynamic properties, suspension and brakes.

On the outside, the CLS gains a wide-body aero kit that includes carbon-fiber fender flares on the rear axle that add 40 millimeters (1.6-in.) to the car's width, front and rear spoilers, a diffuser and more.

The Rocket 800 rides on 19-inch one-piece BRABUS Monoblock F wheels wrapped around tires in size 255/35 ZR19 up front and 285/30 ZR 19 in the rear.

Finally, interior improvements include a bespoke steering wheel, aluminum trim, custom upholstery and a revised instrument panel with a 400km/h (250mph) speedometer.
