Mercedes Benz unveiled Grand Edition CLS

Mercedes-Benz has introduced a special edition version of its recently updated CLS four-door coupe model. The CLS Grand Edition is part of Merc's new factory program called "designo" that offers buyers more exclusive options and differentiation within a model's line-up. In the case of the CLS Grand Edition this means a new platinum matt finish which is allegedly highly scratch- and dirt-resistant.

One of the most immediately noticeable features of the CLS Grand Edition is the matte platinum paint. Just as white is being dubbed the new black, so too is matte overtaking gloss finishes among style-conscious carmakers. The Lamborghini Reventon is a notorious example. Obsidian black, iridium silver, carneol red and flint grey metallic finishes are also available for the Grand Edition, however.

The additional exterior equipment for the CLSGrand Edition includes Bi-xenon headlamps with dark headlamp casings, new high-sheen AMG18-inch 5-spoke light-alloy wheels shod with 245/40 R 18 (front) and 275/35 R 18 (rear) tires and a "Grand Edition" insignia on the front wings. Inside, the car gets a roof lined in Alcantara, a tilt/slide glass roof, leather upholstery, laurel wood trim - available in both matte and gloss finishes - and a wood/leather steering wheel. Aluminum and brushed stainless steel trim elements finish off the cabin's unique look.

There are four engines available for the Grand Edition trim for the buyers to choose for. These engines include the CLS280 with the entry-level V6 and the CGI direct-injection engine found in the CLS350 CGI, which generates 292hp (215kW) while managing fuel efficiency of 25.8mpg (9.1L/100km).

Hamann provide upgrade kit for Bentley GT and GT Speed

Hamann is well known for its work with BMW's machines but now they started to goes for other which is upgrading the Bentley Continental GT and GT Speed. However the details of the upgrade kit have not reveal yet but Hamann has released four photos for it.

From the photos we can see an upgraded aero kit along the lower edge of the car including dramatic intake scoops below the headlights, a lowering job which suggests re-tuned springs and dampers for improved handling. A set of new 22 inch alloy wheels with black spokes and polished lip is fitted to the car as well.

Expect power upgrades to go along with the aerodynamic and handling modifications, though with the GT Speed already generating a heady 600bhp (441kW) and 750Nm (553ft-lb) of torque, adding to those figures will require some special work. The Continental GT line is no stranger to modification, however, so there is potential for more to be done.

For the interior, the modded Bentleys get a custom leather and white carbon fiber treatment to replace the typical wood accents. Hamann logos and special red piping complement the various interior elements as well, though whether it comes off as an upgrade to the already opulent original interior will remain to be seen in high-resolution photos.

HUMMER H3 supercharged by Geiger

Geiger has unveiled their latest project which is the supercharged Hummer H3. The stock H3 comes with a 3.7-liter inline-five producing a paltry 239 horsepower and 241 little torques, though it is available with a 5.3-liter V8 which still only manage 300hp and 320 lb-ft of twist. By adding a supercharger to the engine, the performance able to produce 423hp and 502 lb-ft of torque. So equipped, the 5000-pound Geiger'd Hummer can reach 60 miles-per-hour in an admirable 7 seconds. 380mm discs gripped by six-pot calipers bring it all back to a halt, surrounded by 22-inch wheels bearing 305/40 Continental rubber.

For the interior, decked out in carbon fiber, is a matter of taste, Geiger revives classic racing livery: After their custom H2 popped up in a baby-blue and orange Gulf scheme, this H3 brings back the iconic striped white Martini livery popularized by Lancias on the rally circuit and Porsches on the track.

Ford released 2010 Shelby GT500

Ford has unveiled their latest 2010 Shelby GT500. The latest in the Shelby line, the 2010 GT500, is primed to carry on the tradition, taking the title of Ford's most powerful SVT-tuned Mustang ever.

Like the other Mustangs, the GT500 is mechanically an evolution of the older model. Just as Ford used the current-gen Bullitt model as the starting point for the 2010 Mustang GT. The performance of the car is estimate around 540 hp and 510 lb-ft of torque. This thanks to the supercharged 5.4L V8 engine.

Exterior appearance changes for 2010 are similar to those found on the standard 2010 Mustang. The redesigned slimmer look, improved interior and modernized trim all carry over where they are not replaced by unique elements. Special attention was paid to the front end of the car, which gets a redesigned splitter among other upgrad

For the suspension system, the car gets a new SVT tuning with revised spring and damper rates for better roll control, thanks in part to work done in the GT500KR program. A set of 19 inch forged aluminum wheels wrapped with Goodyear F1 Supercar is fitted to the car and this help to enhance the handling of the car.

9ff Cayenne Vantage GTR

9ff a well known German tuner specialist for Porsches has came out their latest project which is the Cayenne Vantage GTR. It's based on the Cayenne SUV and has nothing to do with the 911-rivalling Aston Martin, but the 9ff sport-ute packs a mighty punch. With a whopping 725hp on tap, the Vantage GTR leaves other modified Cayennes in its dust – make that a big cloud of dust – and straight into Gemballa territory, which is an insane place to spend any amount of time.

For the exterior, 9ff has decked out this Cayenne in Tumbler-worthy bodywork and sinister matte black finish, and is apparently even offering a revised front end to replace the stock model's angular headlights with round 911 units.

Fisker Karma S 'Sunset' Concept

Recently, Fisker has announced plans to debut their new Karma S 'Sunset' Convertible concept at the North American International Auto Show in Detroit next month. The company has been tight-lipped about the concept but judging by the name it will most likely be based off the production version of the Karma sedan that will also debut at the show.

Besides the green Karma, Fisker is perhaps best known for their coachbuilt SLs and BMWs, but Henrik Fisker is also one of the most influential designers in the last decade, with most of the current Aston Martin lineup and the late, great BMW Z8 attributed to his pen. We can't wait to see what this wunderkind is up to now.

A flashy new door insert that looks as if it could also double as some sort of engine bay vent extends a swooping flare down the side of the car as well. The split-spoke alloy wheels are also of a different type than those of the Karma, though they do share a sort of familial look.
