A Geneva Motor Show isn’t at all complete without the participation of one of the best tuners in the world, one that also calls Switzerland its home.

Days before the opening of one of the biggest auto shows in the world, we finally get an idea what Mansory has up its sleeve. One of their Geneva presentations is a new program for the McLaren MP4-12C, which comes complete with a full aero kit and a significant performance upgrade.

Diving into the body package, the British supercar received a host of new components, all of which were designed to deliver improved aerodynamics. The ultralight bonnet with exposed carbon fiber sections and the proprietary daytime driving lights are a good place to start. The program also comes with a new front and rear apron, new mirror housings, newly designed side sills, a new rear wing profile, and a new diffuser. All the components of this aero kit are made of carbon fiber, providing improved acceleration and braking power, while also improving the supercar’s fuel consumption due to the drastic weight savings.

As for the interior, Mansory knows only to use the finest materials in their programs and it’s no exception on the MP4-12C, thanks to plenty of high-quality leather stitched with contrasting thread by the in-house saddlery. In addition, there are also plenty of carbon fiber elements, as well as a newly designed airbag sports steering wheel and aluminum pedals.[...]

Ruf is just one of the many tuners that are showing up in Geneva with models ready to light up the stage. In fact, Ruf is showing up with about six vehicles, providing just an initial of their names: "the new stunning "CT...", the new rocket "Rt...", the new racer "RG...", the new luxury "RX...", the grandfather of RUF Turbo cars, and last but not least one more surprise!

We haven’t figured out the surprise just yet, but we did happen to come across the first image of their Cayman-based CTR3 Clubsport - the first from the long list of debuts in Geneva. The CTR3 Clubsport will be an evolution of the current CTR3 supercar and, judging from the first picture, it will look amazing.

The standard CTR3 is powered by a 3.8-liter twin-turbocharged flat-six cylinder engine that produces an output of 750 HP at 7,100 rpm and 708 lb/ft of torque at 4,000 rpm. It sprints from 0 to 60 mph in just 3.2 seconds and can hit a top speed of 236 mph.[...]

It's been almost two years since we featured an E85-fueled Nissan GT-R from Switzer. Since then, the Ohio-based tuner has been steadily improving their cornfed-Godzilla conversion package to the tune of a nearly 25% power jump.[...]

Earlier today, we told you that German aftermarket developer Ruf is preparing to give us no less than six customized Porsches at the upcoming Geneva Motor Show.  The company didn't release too many details about its Swiss offensive, but now a photo of the new Clubsport version of the CTR3 has leaked and we're guessing that this is the mysteriorus racer on the list.

The photo was taken inside the Ruf hq by a reader of Speedheads.de and posted on the blog's Facebook page. We'll remind you that ... [...]

German tuner Gemballa, which reinvented itself last year after its owner was murdered, is now ready for a fresh start and will use the upcoming Geneva Motor Show to brings three new goodies.
The first will be the McLaren MP4-12C GT3 race car (the one you see picture here), a development based on the 991 generation of the Porsche 911, as well as the second stage of its aftermarket program for the Cayenne.

We musn't forget that Gemballa has always had a deep passion for Porsche vehicles, so ... [...]

Ruf is one of the top Porsche tuners in the world and the company wants to display an explosion of models at the upcoming Geneva Motor Show, where it will offer us no less than six new developments.

The company hasn't mentioned the exact details for the upcoming models, only offering us a few hints. The vehicles will be based on the 911 and maybe on the new Boxster, which will make its debut at the Swiss event (this is just a guess), with Ruf letting us now that it will present the following ...

A little bit earlier, we showed a 472 hp VW T5 van that German tuner MTM will present at next week's Geneva Motor Show. The aftermarket developer will also offer a less extreme project at the Swiss event, in the form of a modification pack for the Audi Q3 2.0-liter TFSI.

The engine was boosted from the factory stock 170 to 310 hp (this is the usual maximum power safe value for VW's 2.0 TFSI unit), which means that the vehicle now only needs 6.1 seconds to cover the 0 to 62 mph sprint, while i... [...]

German tuner MTM is preparing some pretty extreme developments for next week's Geneva Motor Show and we're here to talk about our favorite one. MTM has played with the T5 van, creating the T 500 2.5 TFSI 4motion. Well, the name kind of says it all: yes it does come with almost 500 hp and if the 2.5 TFSI designation sounds strange it's because such an engine doesn't exist - it was basically created by MTM!

VW's 2.5-liter inline-five unit has been heavily modified and now produces 472 hp at 6,9... [...]

The Buick Regal, the US version of the Opel / Vauxhall Insignia is set to recive a complete tuning package from US aftermarket parts dealer SLP, with the company using a special name for this.

We'll start with the designation, as SLP has chosen to bring back the GNX moniker from the 80s'. Under the hood, the 2.0-liter turbocharged engine will be boosted from the standard 270 hp to at least 305 hp, which is still less than the Insignia OPC's 321 hp .

In addition to that, the GS will be gif... [...]

Mansory has given the already exclusive McLaren MP4-12C supercar into an even more exclusive car by giving it a racing makeover and of course the obligatory power boost. The car will of course bow at the upcoming Geneva Motor Show, where you will be able to decide for yourself if this is the millionaire's plaything for you.

Thanks to a new performance exhaust, new air intake system and an engine remap, the 3.8-liter twin-turbo unit makes 670 PS 675 Nm (498 lb-ft) of torque. As a result of thi... [...]
