The Porsche Panamera is no slouch in both the speed and style departments. However, just because the Panamera's engine and body aren't broke, doesn't mean that they can't be improved upon. These tune jobs prove that every Panamera could benefit from some carbon fiber exterior upgrades and a few engine mods. Continue reading below to see some of the lightest and fastest Porsche Panameras around.

Edo Competition's "Hellboy" (a Panamera S) has been tuned to output 465hp and 406lb-ft of torque, numbers good for a 0 to 62 time of 4.6 seconds and a top speed of 191 mph. Engine mods include a stainless-steel exhaust system with high performance catalytic converters, high-flow mufflers, new tailpipes, an ECU reflash and high-flow air filters. The carbon fiber body kit is highlighted by a ducktail spoiler made famous by the Carrera RS.

German tuners Hamann gave the Panamera a bulky aesthetic makeover, swapping out most of the wagon/elongated sedan's exterior panels in the process. Hamann's Panamera features wider fender flares, bumpers, wheel arches and a larger exhaust. The tuner house's engine mods added an extra 80hp and 89lb-ft of torque.

Vorsteiner's Panamera V-PT goes heavy on the exterior mods and light on the engine additions. The V-PT comes with a new body kit (obviously) consisting of a new front bumper cover that incorporates a splitter, a removable carbon fiber insert, a ducktail spoiler and an optional carbon fiber duct. Vorsteiner also offers a sport exhaust system made out of stainless steel or titanium, with the titanium version weighing in at 40 percent lighter than the stock version.

TECHart went heavy on the carbon fiber when it customized the Panamera. The TECHart GrandGT features a complete carbon fiber exterior and interior. Everything from the Panamera's front apron to its dashboard is covered in the lightweight material. Despite all of the black carbon fiber, the real winner here is the color red. That red interior stitching and those red brake calipers are surprisingly fetching.

Belgian tuning house Caractere Exclusive joined forces with performance tuners Dynatek to push the Panamera to 596hp. Included in the list of engine mods are new 200-cell catalytic converters and a sport exhaust system from Akrapovic. Aerodynamic mods include a new front bumper with integrated lights, a set of side skirts, a new rear bumper and rear spoiler. The speedy Panamera sits on a set of 22-inch rims in CW1 Graphite or Silver.
