Based on the limited production CLK GTR, the Super Sport represents the pinnacle of Mercedes-Benz development. It is the product of HWA, a specialist firm which helped Mercedes-Benz prepare the original CLK GTRs that raced the GT1 class at Le Mans. HWA is also responsible for creating the 25 road going examples of the GT1 racecar. Among these HWA has prepared five roadsters and two even rarer super sports models having a much larger engine.

Its the new 7.3-liter, AMG engine which highlights the Super Sport’s performance. Increased displacement gives the super sport 100 more horsepower than other CLK GTRs, making this car one of the most powerful, naturally-aspired coupes.

To matching the increased power, the aerodynamics package of the CLK roadster are updated to reflect it’s sporting nature. Specifically, the rear wing is modified and rear view mirrors are different.

Only two of the CLK GTRs originally received the 7.3 engine and a few others were later updated. The first chassis, 1/25 was the homologation car which had a 7.3. This particular car is unique with high-mounted post mirrors and a lack of “clk gtr” badges on the rear panel.

The second car, chassis #017, was modeled after the upgrade on the first car. It came straight from HWA with the 7.3 engine and was the only car to officially receive the Supersport designation. Painted in the unique red over tan combination, Mr.Ilyas Galadari of UAE-Dubai was the first owner. The car was then sold to an owner in Switzerland who took it back to HWA for a coat of silver paint and red interior. Next, the car was shipped to the USA as brokered by thecarexperience.com. They successfully imported the car, and it now resides in the USA.

1998 Mercedes-Benz CLK GTR Super Sport 1/25 – did not sell for $1,200,000 This particular CLK GTR is arguably one of the two most desirable examples. Of the 25 road-going CLK GTRs produced, two were built and heavily modified by AMG’s sister company, H.W.A. GmbH, so named for its president and AMG co-founder, Hans-Werner Aufrecht. H.W.A. did the unthinkable by replacing the CLK’s already potent 6.9-liter V12 with Mercedes’ newer and more powerful 7.3-liter V12 engine, producing a blistering 720 horsepower. Auction Source: 2007 Monterey Preview
