Here’s another tuning upgrade for the Mercedes SLS AMG, adding up to what has become one of the most sought after high-performance project cars in the market today.

This latest piece of work comes courtesy of aftermarket experts RENNtech. You might remember these guys for having already worked on an SLS AMG in the past. This time around, they’re taking their work on the Merc supercar with a new performance upgrade that puts even more ponies under the car’s hood.

The tuning program features the addition of the company’s own tube headers that are made from high quality, tri-metal, 200 cell sport catalytic cells that have been ceramic coated in order to cut down on the heat in the engine compartment while also fighting off the thermal stress that the engine is subjected to. The tube’s design also gives room for the SLS AMG to improve its low end torque numbers and gives the supercar a better overall performance.[...]

 Are you an owner of the diesel-powered Audi A7 Sportback? Do you need more power than what the standard 245HP 3.0-liter TDI V6 has to offer? Well, suffice to say, you probably should have considered the 300HP 3.0-liter TSI petrol model instead?

 Nevertheless, for those of you that fit the description, German firm Senner Tuning has released a new performance package for the A7 3.0 TDI. The makeover of the V6 diesel engine takes output up from 245-horses and 500Nm of torque to 306-horses and 620Nm (457.2 lb-ft) respectively, nudging top speed to 280km/h (174mph).[...]

Project Kahn’s interpretations of the many vehicles crossing its path always end up being tremendous in their own right. From the Porsche Panamera to the Audi R8, the tuner’s packages always come out clean and astounding. Seemingly conquering the aftermarket sports car segment, Project Kahn has now moved on to rock climbers, mountaineers, and off-roaders with their new branch, the Chelsea Truck Company. The new branch’s first task will be to transform a slew of Jeep Wranglers Project Kahn has gotten its hands on.

Chelsea Truck Company’s first conversion of the Jeep Wrangler is subtle and includes a targa roof, specially designed 18 and 20 inch RS wheels in matte black, telescopic headlights, and clear side lights. The inside is striking with red facia dials and claret red quilted perforated leather. Other optional extras are available, but no other details have been released.[...]

Hennessey is one of America's best-known tuning houses offering solutions for a great number of vehicles ranging from Nissan GT-R bashing Caddy Escalades to Ferrari's 458 Italia and anything in between.

 

Having already tuned the sedan and estate versions of the Cadillac CTS-V, Hennessey decided it was time to give a little attention to the coupe version: hence the V1000 CTS-V Coupe was born.[...]

As the tuning world always leaves space for more, and despite the fact that many think that a Jag is as good as it can get, Japanese tuner Wald International comes to proves us wrong. Applying the Black Bison kit we've so far seen on the Lexus LX570, BMW 5-Series F10 or the Bentley Continental Flying Spur, the tuners brought both exterior and interior updates to the car.

The model in question is the previous generation Jaguar XK (X350) which, despite the fact that it is now bearing the word ... [...]

Let's face it: Once you've clad a military truck in fake whale-penis leather, what do you do for an encore? Perhaps wrapping a Bugatti Veyron in red chrome will do the trick. At least for Kostyantyn, the adult-toy-superstore king of Dnipropetrovsk. [...]

Not only does AMS Performance's Nissan GT-R produce over 1300 horsepower at 35 pounds of boost, it knows how to use it. After watching the very impressive 9.05 second 1/4 mile seen here, it isn't too surprising to find out this Nissan is the fastest R35 GT-R in the world.[...]

You know the problem with setting speed records in small cars? Keeping the clowns' helmets from knocking together. Still, MTM's 500hp Audi A1 recently exceeded 200 mph on Italy's Nardo test track. Not bad for something the size of a popcorn bag. [...]
