Mansory->ke3403 is known in the tuning world for a lot of things, but what really sets it apart from the rest of its contemporaries is its ability to build one-off creations for specific people. Just last month, the German tuner unveiled the Rolls-Royce Wraith Palm Edition 999, a nine-off project built for an exclusive lot of people who could afford it. As a follow up to that bespoke wonder, Mansory has unveiled its latest work of art, the one-off Lamborghini Aventador J.S 1 Edition.

Based on the Aventador LP750-4 Superveloce, the Aventador J.S. 1 Edition is a customized project that Mansory built for billionaire art dealer James Stunt. Most people in the industry also know him as the husband of Petra Ecclestone, the daughter of F1 boss Bernie Ecclestone. But that’s a story for another time. This is all about the Aventador J.S 1 Edition, which really makes all other Aventadors->ke5187 look pedestrian by comparison.

First, there’s all that carbon fiber on the body. Granted, a lot of tuners have used the material for their own programs. But rarely has the final product looked like this one. It’s blacked out and dressed to the hilt with pre-preg carbon fiber. More importantly, it also has an engine tune that takes the Superveloce’s 750-horsepower output and brings it up to a level worth its incredulous body.

Mansory has built a lot of these projects in the past, but this one ranks right up there as one of the best ones yet.

Continue after the jump to read the full review.

Exterior

Guaranteeing the exclusive nature of this Aventador, Mansory went to work on building a carbon fiber body kit using the pre-preg method that helps distinguish the product from similar carbon fiber body kits. This is a time-consuming process in it of itself but you don’t expect anything less from Mansory.

Up front, the Aventador gets a redesigned front bumper with air intakes to help improve the ventilation of the radiator. There’s also a new spoiler lip that adds extra downforce while the hood and fenders now come in carbon fiber. New side skirts are also part of the kit, helping improve the flow of air between the two axles. The aero upgrades continue with the larger spoiler and diffuser at the back, completing the carbon fiber kit that not only makes the Aventador J.S.1 Edition look more menacing, but also helps it go on a 110-pound diet.

Interior

The Swiss tuner didn’t dive into the details on what it did inside the Aventador 750-4 Superveloce but a photo shows a two-tone, black-and-white-finished cabin with plenty of leather and Alcantara elements. Diamond-quilted patterns are visible on the on the center stack and carbon fiber can be seen on the door panels. You can tell that there was a great deal of customization done on the cabin, as is often the case when Mansory’s working on an exclusive one-of-one project for a celebrity. If it isn’t obvious enough, the interior also has plenty of references to that fact, particularly on the headrests, the side of the center stack and the floor mats.

Drivetrain

There’s a lot of ‘wow’ factor with this program, which really shouldn’t come as a surprise for a company like Mansory. To give this one-off Aventador, the ultimate distinction, the German tuner added a performance upgrade that adds 80 horsepower and a little over 44 pound-feet of torque to the supercar’s massive 6.5-liter V-12 engine. The result is a total output of 830 horsepower and 553 pound-feet of torque, enough to propel the Lambo to 62 mph in just 2.7 seconds. That’s one-tenths of a second quicker than the standard model. The trip to 124 mph also drops from 8.6 seconds to 8.4 seconds while 0 to 186 mph only takes 23.4 seconds – six-tenths faster than the standard car. Mansory also got the top speed to increase to 220 mph, slightly higher than the supercar’s normal top speed of 217 mph.

Pricing

Custom projects don’t have published price tags for obvious reasons. The sheer complexity of these programs often rely on input from the client. So with somewhat of a free reign to decide on what they’d want, it’s hard to nail down a price for something like the Aventador LP750-4 Superveloce J.S.1 Edition. The best thing I can probably do is give a rough estimate, which likely won’t mean much anyway. But with all these modifications and the nature of the car as a legitimate one-of-a-kind, I’d say that Stunt probably has a bill in the vicinity of around $100,000. That’s just for the kit. Add the $401,000 price of a LP750-4 Superveloce and you’re looking at a car that cost the London-based art dealer in excess of $500,000. I can't imagine Stunt having any difficulty affording that. He is a multi-billionaire, after all.

Competition

Ferrari F12 Bberlinetta Stallone by Mansory

It’s not exactly a one-off, but Mansory’s Stallone program for the Ferrari F12 Berlinetta is just as crazy and just as awesome as the Aventador J.S.1 Edition. From the onset, it has an aero kit that comes with a redesigned front fascia that includes a newly designed bonnet and a down-force-generating front spoiler with special air intakes. It also has side skirts, a subtle rear wing, an integrated diffuser, and a new set of light forged wheels measuring 21 inches up front and 22 inches out back.

As impressive as that is, Mansory’s work on the F12 Berlinetta’s 6.0-liter V-12 engine helped the car increase its output from 740 horsepower and 508 pound-feet of torque to 775 horsepower and 534 pound-feet of torque. The new power numbers help the Ferrari sprint from 0 to 62 mph in under three seconds to go with a top speed of around 217 mph.

McLaren 675LT by Wheelsandmore

Wheelsandmore is widely respected as one of the finest supercar tuners in the business. It proved as much back in November 2015 when it presented its tuning kit for the McLaren 675LT. While it lacks the kind of aerodynamic upgrades that the likes of Mansory is known for, Wheelsandmore did present a special set of 20- and 21-inch 6 Sporz ultralight forged wheels for the British supercar.

Moreover, it also created a special performance kit for the 675LT that includes an ECU upgrade and a new stainless steel exhaust system. The result of this modification saw the 675LT’s 3.8-liter V-8 engine receive 720 horsepower and 553 pound-feet of torque, enough to propel into the realm of true supercars. The German tuner didn’t offer any performance numbers, but it is expected that the 675 LT would be capable of sprinting from 0 to 62 mph in around 2.7 seconds to go with a top speed that’s just north of 215 mph.

Conclusion

I know this kit is a one-off and the chance of Mansory repeating it for someone else largely depends on whether that person likes it or not. But still, this kind of work is one of the biggest reasons why I’m such a fan of the tuner. The attention to detail is just incredible and the way Mansory manages to strike a balance between looks and performance is a skill that’s unique to itself. I'm not really familiar with the work of James Stunt, but for at least one day, I'll give him a round of applause for how this Lamborghini Aventador LP750-4 Superveloce turned out.
