The latest model to receive Wald International's dark "Black Bison" treatment is the Porsche Panamera sports saloon. As usual, the Japanese tuning firm's package is centered on a raft of styling parts with minimal performance upgrades.

The Panamera's exterior receives a comprehensive makeover with a new carbon fiber aero kit that adds a new front bumper with sculpted air vents, rear wheel arch extensions, front fender mesh vents, rocker panels, a deck lid spoiler and a redesigned rear bumper with extra vents and a diffuser.[...]

The world was taken by surprise when British tuner Kahn released a tuning development based on the Land Rover DC100 last year, in the form of the Kahn Defender. However, the base vehicle is just a prototype that's years away from being released, so the tuned example must follow suit.

However, Kahn is now launching a set of wheels developed exclusively for the current Defender, with the 16-inch rims being perfectly suitable for the toughest off-road adventure. Kahn is also planning to release ... [...]

Japanese aftermarket developer Wurde is a company that, among others, likes to play with European toys, with the company's latest project of this kind targeting the Porsche Panamera S.

We are talking about a body kit for the German four-door coupe, which aims to brings a more dynamic image to the vehicle. The list of custom parts consists of a front fascia, headlight ornaments, a redesigned bonnet, new side skirts, a rear diffuser, a set of panels for the rear doors, as well as a rear spoile... [...]

A. Kahn Design ended 2011 with a bang in the shape of a tuning package for the Ferrari California, and it looks like they are starting 2012 in the same way with an upgrade package for the Ferrari 458 Italia. The Ferrari 458 Italia Editions were dressed up in either a triple Pearl White or a Rosso Corsa Red exterior paint finish, both combined with different exterior and interior elements.

The Rosso Corsa Red Ferrari 458 Italia by Kahn is toned down with a matte Pearl Gray finish for the roof, side skirts, and front and rear bumper sections. A. Kahn Design then added a new sport suspension and 9×21? front and 12×22 rear alloy wheels finished in a matte Pearl Gray with yellow brake calipers serving s a small highlight. Inside the Rosso Corsa 458 Italia, Kahn has added a leather interior, a leather central tunnel, Crema Daytona lights, an Electro Chromatic interior, a yellow rev counter, leather headlining, and carpets and stitching in Bordeaux.

The Triple Pearl White 458 Italia by Kahn gets the same wheels associated with the red model, as well as the new sport suspension. The brake calipers are switched from yellow to red. Inside, the 458 Italia receives black Nero leather electric seats, a yellow rev counter, leather headlining, upholstered rear bench seat wall, white stitching, and black carpets.[...]

Talk about a wolf in sheep's clothing. With a few exceptions like the sporty six-cylinder GTR XU1 and the 5.0-litre V8 powered SLR 5000 editions, the Holden Torana was a run-of-the mill compact model with plain Jane looks and lackluster performance.

But in the world of tuning and drag racing even the Torana can be transformed into a terrifying beast. Meet Jakes Edward's latest Torana sedan fitted with a massive 496ci (8.2-liter) turbocharged V8 Chevrolet engine that runs on methanol fuel.

At this month's Summernats festival in Canberra, Australia, Edward's yellow Holden took part and won the "Horsepower Heroes" competition as it yielded 1,584.5 wheel horsepower on the dyno! Watch the Aussie-made monster in the video after the break.[...]

Vossen is currently working on a project based on the F10 BMW 5-Series, with the aftermarket developer recently releasing a photo shoot that previews the development.

The central element is a set of 20-inch Vossen CV3 wheels, which use a concave, five-spoke design that offers an aggressive appearance and come in a dark finish. In addition to that, the 5er has been gifted with multiple tuning goodies, such as a new front fascia, which comes with massive air intakes and uses a bold design.[...]

We aren’t exactly the biggest fans of Ferrari’s latest addition to their lineup, but this FF in particular may just be cool enough to change our mind. You see, the standard Ferrari FF works from a 6,262 cc direct injection V12 engine that delivers an impressive 660 HP at 8,000 rpm and a peak torque of 503 lbs-ft 6,000 rpm, which is fantastic for a car that looks like a stretched out wagon. That being said, Norwegian aftermarket developer, Customised.no, is upping that ante with a bio-ethanol (E85) conversion that will shoot up the power and kick back its emissions. Sounds intriguing.

The E85 conversion jump-starts the FF’s power output by taking it from 660 HP all the way to 875 HP! This newfound power will allow the sports coupe a 0-60 mph sprint time of less than three seconds, improved from the standard 3.7 seconds.

The conversion still doesn’t make the car any prettier, but it does reduce its emissions by about 80%, from the current 360g/km to 100g/km. Kind of impossible to believe considering this is still a Ferrari.[...]

The Chinese are known to have a passion for elongated versions of any car and the latest vehicle to receive such a treatment for what has become the world's largest automotive market is the Porsche Panamera.

The Porsche Panamera long wheelbase has been created by one of the most serious Porsche tuners, Ruf, which has paid a lot of attention to details. The Ruf Panamera XL has been stretched by 40 centimeters, all of which can be translated into rear legroom.

Stretch limos based on supercars always tend to fall in the overkill category and the example from the adjacent photos is no exception. We are talking about a stretch limo based on the Audi R8, a vehicle that is being previewed by a British limo hire company.

Limo Broker is introducing the Audi R8 limo, a vehicle that can swallow up to eight passengers and uses the R8's 5.2-liter V10 engine, promising to offer a top speed of 196 mph (315 km/h) - allow us to take this one with a grain of salt,... [...]

RENNtech is the basically as dedicated as you can get to creating custom Mercedes that go really fast, though they sometimes play with BMWs or Porsches as well. And while they do make anything from adaptive suspension to a full exhaust for the Mercedes Benz SLR McLaren, there isn't an invisible trunk option on the market as far as we know.

Before you burn us for getting it wrong, this video does not show an actual record-setting run, only the car that hold the title. But with a quarter mile r... [...]
