As the Deutsche Tourenwagen Meisterschaft/International Touring Car Championship had folded in late 1996, with both remaining competitors Opel and Alfa Romeo leaving due to the high costs of their 4WD designs, Mercedes-Benz had no top series to compete in. With the success of the BPR Global GT Series leading to the FIA taking over and turning it into an international series known as the FIA GT Championship, Mercedes-Benz saw an opportunity to go against manufacturers like Porsche and Ferrari.

Following the design that Porsche had laid out with their 911 homologation special, the GT1, AMG was tasked by Mercedes-Benz with creating an extreme racing car that still maintained some elements of a normal street legal car. AMG's designers and engineers designed and developed a car which shared some design elements with the Mercedes-Benz CLK, yet had all the standard features of a racing car underneath. A Mercedes-Benz M120 V12 engine would be at the heart of the car, mounted behind the cockpit. The bodywork would be made entirely of carbon fibre, and would have many aerodynamic design elements and cooling vents in order to survive on the race track.

To test the CLK GTR before the actual cars were built, AMG actually took an unusual measure. Through secrecy, AMG was able to purchase a disused McLaren F1 GTR, the defending BPR GT series champion, from Larbre Compétition. This purchase first allowed AMG to see the kind of lap times that their competitors could run, to serve as a measurement of the CLK GTR's abilities. However, more importantly, AMG set about modifying this F1 GTR by attaching bodywork that was meant to be implemented on the CLK GTR. Mercedes-Benz also used their own LS600 6.0-litre V12 engine in place of the BMW V12 unit.^[7] This allowed AMG to be able to perfect the aerodynamics of the car before it had even been built.

Upon completion of the first two prototypes in a mere 128 days after the initial drawings had been made, the CLK GTR was entered into the 1997 FIA GT Championship season, debuting at the season-opener at one of Mercedes-Benz's home tracks, the Hockenheimring. Unfortunately the new cars were not able to shine, as brake problems eliminated one car after five laps, and the other finished over 20 laps behind the winning McLaren. However, by the next round at Silverstone, the CLK GTR began to show its pace, finishing less than a second behind the winning McLaren. By the fourth round, returning to Germany for the Nürburgring, a third CLK GTR was added to the team. In this race, Mercedes-Benz successfully outperformed the fleet of McLarens, taking first and second places. The team would finish out the season with five more wins, at A1-Ring, Suzuka, Donington, Sebring, and Laguna Seca, allowing them to secure the team championship as well as the drivers championship for Bernd Schneider.

Mercedes-Benz would use the CLK GTR for the first two rounds of the 1998 season before switching to the CLK LM. However privateer team Persson Motorsport would campaign two CLK GTRs throughout the entire season, taking a best finish of second at Oschersleben before finishing the year third in the teams championship.

Initially the CLK-GTR's V12 engine generated a power output of approximately 608 PS (447 kW; 600 hp) and 538 lb⋅ft (729 N⋅m) of torque.

CLK LM [edit]

After conquering the FIA GT Championship, Mercedes-Benz set its sights on competing at the 24 Hours of Le Mans in 1998 after their departure in 1991. However, Le Mans presented a different challenge from what was offered in the FIA GT, in that the race distances were nearly one tenth the distance covered at Le Mans. Therefore, Mercedes-AMG set about to modify the CLK GTR in order to meet the new demands required at Le Mans.

First and foremost, AMG decided that the M120 V12 would not be up to the task of running for 24 hours. Instead, they decided to use the M119 HL V8 engine from Sauber C9/Sauber C11 which raced in the late 1980s and early 1990s, as AMG felt that the M119HL would have better reliability at speeds while still providing the same amount of power output as the M120 due to air restrictor regulations. The turbochargers were removed and other revised components were added in order to achieve high rpm.^[8] The modified engine was designated as GT108 B.

Satisfied with the engine, AMG also set about altering the bodywork to better cope with the high speeds achieved at Le Mans. The nose was lowered and the large front brake cooling ducts on the sides of the nose were removed and replaced by a single, large opening in the front of the car. The roof of the car was also lowered and a new engine air intake was designed for better engine cooling along with various other mechanical modifications. This new car would come to be known as the CLK LM, with the LM designation standing for Le Mans.

Debuting at the 1998 season of Le Mans, the two CLK LMs entered were immediately quick. The two car team took the pole, ahead of custom built open cockpit Le Mans prototypes. However, AMG's belief of the M119LH engine's reliability and capability was proven wrong as both cars suffered engine failures within the first few hours of the race, leaving Mercedes-Benz dejected.

Returning to FIA GT, Mercedes-Benz replaced their older CLK GTR with the new CLK LM and saw greater success. The two cars easily won every remaining race, including six 1-2 finishes. This handed Mercedes-Benz the teams championship again, while Klaus Ludwig and Ricardo Zonta would share the drivers championship.

For the 1999 season, no competitor attempted to enter the GT1 class in FIA GT except for Mercedes-Benz, forcing FIA to cancel the class, similar to the DTM/ITC two years earlier. Mercedes-Benz thus turned to constructing an all-new car to overcome their failure at Le Mans. No longer forced to build a racing car that could also be a road car, they newly-purchased Mercedes-AMG set about creating the Mercedes-Benz CLR.

The CLK LM's V8 engine generated a power output of approximately 608 PS (447 kW; 600 hp), allowing it to reach speeds up to 330 km/h (205 mph) which was achieved during testing for the 1998 24 Hours of Le Mans disregarding a claimed virtual top speed of 335 km/h (208 mph).^[9] In total, five cars were constructed, with one test car for crash testing. Two road-going versions were built to comply with the 1998 FIA regulations (one later destroyed for crash testing purposes),^[10] and three race versions were constructed. Chassis #005 was sold by Mercedes AMG to a private collector in Japan after the 1998 season and has since changed ownership, but remains in private hands along with the road-going version.^[11]

Even though the FIA GT1 class was cancelled in 1999, Mercedes was obliged to finally deliver the required minimum 25 road cars they had promised as per FIA rules. An initial road car was built in 1997 in order to meet initial FIA requirements, but this car was retained by Mercedes. For the other road cars, each was built by AMG at the Affalterbach factory between the winter of 1998 and the summer of 1999 and differed only slightly from the race car. Driver comfort and refinements were at a minimum in the construction of the road cars as Mercedes-Benz wished to not only offer customers a true race car, but also to attempt to keep the price low. The interior was upholstered in leather and an air conditioning system was offered. Two small storage lockers were also built underneath each upward swinging door. Traction control was also added for driver safety.

The road car retained much of the design of the original CLK GTR instead of the CLK LM, including the V12 engine and many design elements. One key difference was the rear wing, which was a hoop-style integrated wing in place of the fixed separate racing wing on the road car. The road car shared only the rear lights and the quad-headlamps with the Mercedes-Benz CLK.

Ilmor Engineering provided enhancements to the engine, increasing displacement from 6.0 L (5,987 cc) to 6.9 L (6,898 cc), once stroked up to 92.4 mm (3.64 in). This increase in displacement coupled with the removal of an air restrictor allowed for a maximum power output of 612 PS (450 kW; 604 hp) at 6,800 rpm and torque of 775 N⋅m (572 lb⋅ft) at 5,250 rpm. Mercedes-AMG claimed a 0–100 km/h (0–62 mph) acceleration time of 3.8 seconds and a top speed of 344 km/h (214 mph).

The Guinness Book of World Records recorded the CLK GTR as the most expensive production car ever built at the time, with a price of US$1,547,620.

Two road car prototypes were manufactured and do not have a numbered plaque that the subsequent production cars have on the door sills and centre console respectively. These prototypes have a plaque with the "Limited Edition" label. The second prototype (VIN WDBA2973971Y000002) was auctioned in 2003 by Bonhams for 800,000 Euros.^[14]

Twenty coupés were made separate from the pre-production cars and each have a serial number labeled 01/25 through 20/25. No coupés were manufactured with the numbers 21/25 through 25/25. Instead, these numbers represented the initially planned five roadsters (an additional sixth roadster was made at the end of production run). While most of the coupes are finished in silver, chassis #19 has a dark blue paint scheme while #20 has a black paint scheme. Chassis #17 was formerly painted red but was repainted in silver when sold by Ferrari of Fort Lauderdale.^[15] Prototype #1 and production cars bearing chassis number #05, #07, and #13 have tartan interiors.

Two of the 26 cars produced were equipped with RHD steering: one coupé (chassis number #13, silver exterior/tartan interior) and one roadster (chassis number #2, dark silver exterior/magenta interior).^[16] These were constructed for Hassanal Bolkiah, the Sultan of Brunei.^[17] Both RHD cars were auctioned on 28 October 2009 by RM Auctions in London.^[18] The roadster was sold for £616,000 (US$973,834) and the coupe for £522,500 (US$824,609).^[19]

CLK GTR Roadster [edit]

After the completion of the 20 original CLK GTR coupés, AMG's specialist group H.W.A., who had assisted in the construction of the CLK GTRs, began construction of a roadster version of the CLK GTR. Built either by modifying an existing CLK GTR or by building a new car from spare chassis and parts^{[ clarification needed ]}, these cars were modified with the removal of their roofs as well as a reconstruction of their engine covers. Additionally, the rear wing was replaced by a separate black wing, close to the one on the racing version of the CLK GTR and the wing mirrors were mounted on the doors instead of the front fenders. Further, the Roadster is recognised by its different front grille, which has an integrated large three-pointed star instead of a small version above it. Two rollbars integrated in the cockpit headrests were used not only for structural integrity, but also for rollover protection. The roadster was 105 kg (231 lb) heavier than the coupé.^[20]

A total of six CLK GTR Roadsters were built by the company. Roadster chassis #1 was the only roadster painted in black and #2 was painted dark silver with a magenta interior. The remaining four were painted silver and have various interior colours.

CLK GTR Super Sport [edit]

H.W.A. also constructed a second variant, known as the CLK GTR Super Sport. These cars were similar to CLK GTRs, yet were powered instead by the newer Mercedes-AMG 7.3 L (7,291 cc) V12 which had been in use in the Pagani Zonda and Mercedes-Benz SL73 AMG. The engine generated a power output of 721 PS (530 kW; 711 hp) at 6600 rpm and 786 N⋅m (580 lb⋅ft) of torque at 5250 rpm The car also gained an additional front splitter for better stability at high speeds. Only five were built with the 7.3 litres (7,291 cc) engine: prototype #2, chassis number #01, #03, #13, and #17.^[20]

CLK LM road car [edit]

Massive changes to the CLK LM required Mercedes-Benz to built another road car to homologate the evolved model. The CLK LM's road car was visually identical to the racing counterpart, with the rear wing and interior similar, if not identical, to the CLK GTR road car. Two road cars were built, with only one car surviving; the surviving road car was first publicly shown in 2014 after being purchased from a Japanese collector.^[10] When the car was submitted to FIA for homologation, it sported a different front bumper, while the final road car used the exact ones from the racing counterpart.^[21] ^[22]
