MY FEEDLY: Paris-Dakar Rally Specification: Mercedes-Benz 450 SLC 5.0

The Mercedes-Benz 450 SLC 5.0 may not seem like the first vehicle you would choose for endurance racing, but back in the late 1970s and early 1980s the car became an unlikely hero – winning many of the world’s toughest endurance rallies, often with a 1-2 finish.

Mercedes had developed the 450 SLC 5.0 specifically to homologate the model for the 1978 World Rally Championship, with a new engine and a number of modifications to make the car lighter and better suited to racing.

Fast Facts – The Mercedes-Benz 450 SLC 5.0

The Mercedes-Benz 450 SLC 5.0 became one of the most successful endurance rally racing cars of its time, with a 1-2 finish in the 1978 Vuelta a la América del Sur, a 1-2-3-4 finish in the 1979 Bandama Rally in Côte d’Ivoire, a 2nd in the 1979 Safari Rally, a 1-2 in the 1980 Rallye Côte d’Ivoire after which the factory team was disbanded.
After the factory team had been dissolved Albert Pfuhl bought all the cars and equipment, consisting of six 500 SLCs, spare parts, and 600 tires.
Pfuhl and his team would build a series of cars to compete in the 1984 Paris–Dakar Rally with a distinctive blue and white “BOSS” livery. Though the drivers put in their best efforts the cars finished well down the order, marking the end of the competition life for the model.
Today the 450 SLC 5.0 and its close sibling the 500 SLC remain lesser known race winning homologation specials, often a little more affordable than their period competitors.

The “Panzer Wagon” R107 + C107

Not long after the Mercedes-Benz 350 SL and SLC models were introduced in 1971 the model family was nicknamed the “Panzer Wagon,” after the relatively heavy kerb weight of 3,500 lbs (1,590 kgs).

The Panzer, or Panzerkampfwagen, was of course a hefty German battle tank used during the Second World War.

The internal model names for the SL and the SLC of this generation were R107 and C107 respectively, the letter stands for either “roadster” or “coupe,” and 107 was the chassis designation. It would be the second longest running model series for Mercedes, running from 1971 to 1989, beaten only by the G Wagon.

The reason the R107/C107 is a little on the heavy side is because it was designed more as a GT car than a sports car, in an era when Mercedes were building cars to last indefinitely, rust permitting.

The structure of the model series used steel unibody construction with independent front and rear suspension, disc brakes front and rear, and a front engined, rear wheel drive layout. The model was initially offered with the 3.5 liter Mercedes V8 and either manual or automatic transmissions, later a variety of V8s and inline-sixes were also offered.

In total, Mercedes built over 300,000 examples of the R107/C107. They’ve largely stood the test of time thanks to their sturdy construction and reliable drivetrains. The biggest problem for them tends to be the same problem faced by all steel-bodied vintage cars – corrosion.

Thanks in part to the fact that so many were made the Panzer Wagon remains quite affordable in most world markets, depending on the specific model of course.

Most were built with automatic transmissions so manual cars tend to fetch a premium, but companies like the SL Shop sell bolt on kits to convert autos to manuals over the course of a weekend.

The Dakar Mercedes-Benz 450 SLC 5.0 Shown Here

The Mercedes-Benz 450 SLC 5.0 you see here was given a comprehensive rebuild to historic Paris-Dakar Rally specification by specialists SLC Racing in Slovakia four years ago. The total cost of the build was over €150,000 ($170,000 USD).

The 450 SLC 5.0 was a special homologation version of the 450 SLC fitted with the new all-aluminum version of the Mercedes-Benz M117 V8 engine with a displacement of 4990cc, 240 bhp, and 88 lbs less weight than the comparable 450 SLC V8 with its iron block.

Further weight reduction was undertaken in the construction of the body, with the hood, trunk lid, and wheels now being made of aluminum-alloy. The total weight reduction was said to be over 100 kilograms or 220 lbs.

This car was carefully built to Paris-Dakar specification by SLC Racing in Slovakia, the total cost for the build was over €150,000 ($170,000 USD). It would would likely make an excellent entry into the new Dakar Classic class if the new owner so wishes.

Just 2,769 examples of the 450 SLC 5.0 were built for homologation purposes between 1977 and 1981, they’re now among the most collectible of all the C107 SLCs.

Though not originally designed with endurance rally racing in mind, this is just what Mercedes did with the model starting in 1978 with a 1-2 finish in the Vuelta a la América del Sur, a grueling 7,000 kilometer race leaving from Buenos Aires and returning in a loop via Rio, Manaus, Caracas, Bogota, Lima, La Paz, Santiago, and Ushuaia.

In 1979 legendary rally driver Hannu Mikkola won the 1979 Bandama Rally in Côte d’Ivoire, with other 450 SLC 5.0s finishing 2nd, 3rd, and 4th. Victory in the 1979 Safari Rally was lost due to suspension damage but the car still managed a strong 2nd place, followed by a a 1-2 in the 1980 Rallye Côte d’Ivoire.

The last major rally outing for the model, now known as the 500 SLC, would be the 1984 Paris-Dakar Rally wearing a distinctive blue/white Hugo Boss livery, front bull bar, lifted suspension, and larger tires for handling desert sand.

The 500 SLCs would finish way down the order, classified 44th and 62nd, spelling the end of the model’s competition career.
