Hennessey Performance is bringing a bit more class to their Cadillac CTS-V V700 package by dropping it into one of the rarest Cadillac CTS-V models ever: the Black Diamond Edition with a manual transmission. Now owners of the exclusive Black Diamond can also take part in the 707 HP madness that was provided to the standard model last year.

The Black Diamond CTS-V features a dark tri-coat paint an embedded with SpectraFlair Bright Silver pigment. This special pigment uses aluminum flakes encapsulated in a glass-like substance called magnesium fluoride. The result is a paint that has a diamond-like sparkle as light hits the surface from different angles. The special exterior paint is further highlighted by Satin Graphite 19-inch wheels with yellow Brembo brake calipers and a special Midnight Sapele wood trim.

Earlier this year, BMW tuning specialist Hamann Motorsport teased its tuning program for the freshly launched 6-Series Convertible with the release of the first photos of the car.

The dog days of summer are just about here and SR Auto Group is preparing for the heat with a cool new "LP560-4 Berzerk" package based on the Lamborghini Gallardo.

A car such as the Gallardo cannot be trusted to just about anybody, but SR Auto Group has consistently prepared dominating packages for the super car and their latest project is certainly no different. Being a natural beauty to begin with, the LP560-4’s body was accentuated with the use of clean, sophisticated lines provided by a two-tone finish front bumper, carbon fiber side skirts, and a carbon fiber rear spoiler. The polished look was then capped off with an Ocean Blue paint job and new set of Monotec T04 wheels offered in size 20" and painted in a gloss black finish.[...]

Velocity stacks are the lace teddies of high-performance engines. So when a client of Chicagoland's Fluid Motorunion wanted aluminum horns for his BMW M3, they ran to the AutoCad and created a mockup. Then, they carved out these nasty sombitches in three dimensions. [...]

ABT Sportsline has made tuning projects of the Audi A1 in the past, but their latest program for the German automaker’s sports hatch figures to be one of the most powerful A1’s this side of Audi’s out of this world, 500-horsepower A1 Clubsport Quattro.

Dressed in three unique color schemes - the Aloha, Klecks, and High Voltage - the 2011 iteration of their A1 package also comes with a prominent engine upgrade. Incidentally, these three color schemes also came with the 2010 ABT program, but that’s not the important thing. What’s new and different about the 2011 version is the powerful engine upgrade the A1 received that saw its output increase past the 200-horsepower mark. [...]

Every year, Ford rolls out a special edition one-piece Mustang for the very purpose of auctioning it off at the EAA AirVenture in July for the benefit of the EAA Young Eagles program. These babies - as with all one-off edition cars - are exceedingly rare for the very simple reason that there’s only one of them being made.

This year, the one-off, aviation-themed Mustang GT was built to celebrate the 100th anniversary of naval aviation. It comes with a specific blue-and-yellow color scheme that takes itself from the colors of the ’Blue Angels’ fighter group with a yellow "Blue Angels" script and crest on the doors. Likewise, the crest can also be found on the interior of the car, where they are stitched into the leather Recaro seats.[...]

The Hennessey Venom GT may not look the part of a Veyron-slayer, but we’ve always come to realize not to judge cars by their outward appearance.

This little monster is the perfect example of what we’re talking about.

The Lotus-derived, American-tuned supercar packs plenty of punch with its 6.2-liter LS9 V8 engine that produces an insane 800 horsepower. And if you just happen to be spending your time at the Goodwood Festival of Speed, you can get a chance to see the Venom in all its glory. [...]

It's safe to say that the Nissan GT-R has created a tsunami of emotions that is traveling around the globe and can't be stopped. From the first moment Nissan released the car, the company made it clear that tuners should not mess around it it. The carmaker was so serious about this that it threw a you'll lose the warranty! ball in the game.

What was the result of all that? More and more aftermarket packages being developed, bought and used for offering thrills to drivers from all over the [...]
