When you think of the term “Stealth,” the last thing that comes to mind is a bright-orange CLS63 AMG with nearly 800 horsepower screaming down city streets. Well, apparently the folks over at German Special Customs couldn’t care less what you think about the term, as they rocked the CLS to supercar status and called it just that: Stealth.

On the outside, you get the already sexy coupè look wrapped up in a super-bright shade of orange that is ripped straight from the Aventador’s color palette. Up front, GSC adds in an aggressive front bumper with integrated LED daytime running lights, a mean-looking hood with monstrous heat-extracting vents and all-new fenders that cap off the vicious front end.

Around the backside, you get an all-new rear bumper cover that boasts a carbon-fiber diffusor to help pull the back end down at high speeds. A high-grade-steel four-pipe exhaust system is one with the diffusor, giving the CLS 63 a clean finish and a rather mean exhaust note.

Also added into the mix is a set of wheels size 20-by-9 inches up front and 20-by-10.5 inches on the back wrapped up in super-sticky Michelin tires sized 255/30R20 and 305/25R20, respectively. This sticky rubber is combined with a KW coil-over suspension system and adjustable dampers to make this massive performance coupè even more competent in the twist.

Inside, you also get a tasty treat, as GSC fits the CLS63 AMG with orange Lambo leather and a slew of carbon-fiber components.

What makes the Stealth so bad-ass is what’s under the hood. The 5.5-liter twin-turbocharged V-8 engine was already powerful from the factory – 518 horsepower and 516 pound-feet of torque – but GSC did it one better. The tuner pumped this V-8’s output up to 750 horsepower and 1,150 Nm (848 pound-feet) of torque. This drops its 0-to-100 km/h (62 mph) time down to just 3.7 seconds and bumps its top speed up to 350 km/h (217 mph). That’s a good 0.7 seconds faster to 100 km/h than the stock CLS63 AMG.

Unfortunately, GSC didn’t offer up a price on this beastly kit, but you can contact them at info@germanspecialcustoms.com for pricing details. We’re sure it is somewhere near the €50,000 ($65,000) mark.

German Special Customs Mercedes-Benz CLS63 AMG

Conspicuous Stealth Fighter

In fact, be it on land, water or in the air, the performance specification of any stealth vehicle seeks to produce a vehicle that is as inconspicuous as possible. And given this definition, one may be tempted to assume that the finishing specialists of German Special Customs chose the name “Stealth” for their new aerodynamic construction set for the current Mercedes-Benz CLS63 AMG (C218) with a wink. A stealth CLS is definitely everything else but “inconspicuous”. Particularly if it pops up – as in the example shown here – in a luminary orange color from the Lamborghini Aventador color range!

The front bumper bar of the Stealth with integrated LED daytime running lights looks clearly more forceful and aggressive than its serial counterpart and boosts the already acclaimed non-insignificant passing clout of the CLS63 AMG in combination with the new engine hood and its opulent hot air outlet in an even more significant manner. New fenders and new side skirts with shaft underscore the visual dimension of the four-door coupé. The rear section also appears clearly more aggressive than in the serial model thanks to a completely new bumper with integrated carbon-fiber diffuser and side air outlets. The angular end-pipes of a four-pipe sports exhaust system made of high-grade steel were integrated in the diffuser.

This announces the audible showcasing of the power of the German Special Custom’s CLS63 AMG. This is because the 5.5 liter Biturbo-V8 extracts a hefty 750 Horse Power and a brute maximum torque of 1,150 Newton meters from the tuner. To generate this additional performance of good 225 Horse Power as opposed to the serial vehicle, GSC engineers offered the “eight pointer” amongst others, one set of bigger turbo charger, an additional water cooler for the charge air intercooler and a new exhaust system. Equipped in this manner, the Stealth-CLS sprints from 0 to 100 km/h in just 3.7 seconds, transcends the 300 km/h sonic barrier and then accelerates further up to 350 km/h. For a more optimized road handling, German Special Customs installed a KW coil-over suspension with adjustable dampers on the front axle. The mounted Michelin high-performance tires of the dimensions 255/30R20 and 305/25R20 made of the own-brand alloy wheels of the dimensions 9x20 and 10.5x20 inches generate sufficient grip.

Of course German Special Customs did not miss out on ennobling the interior of the four-door coupé limousine: analogous to the exterior casing, the passenger gets a colorful ambience with orange-colored Lamborghini leather and diverse carbon applications.

I love how the interior’s colors blended so well. Orange and black really complement one another. Better road handling, eight pointer, additional water cooler and great wheels sound good to me.
