Daimler press release:
Spa-Francorchamps (Belgium) – Wide, spectacular and clad in an authentic racing car outfit – two very special S-Class saloon models from the AMG stable. One is the racing touring car of 1971, the 300 SEL 6.8 AMG, and the other is the S 63 AMG showcar. With identical sponsoring and the memorable start number “35”, the new high-performance model is a reminder of an historic success: on 25 July 1971, the bright red four-door saloon crossed the finishing line in second place at the 24-hour race in Spa-Francorchamps. This triumph in the car’s very first race made AMG world-famous overnight.
The highly experienced Hans Heyer and Clemens Schickentanz took turns behind the wheel of the AMG touring car. AMG was anything but the favourite to win this classic Belgian long-distance race: it faced the mighty opposition of the Ford Capri RS, BMW 2800 CS, Chevrolet Camaro, Opel Commodore and Alfa Romeo GTA. Nobody expected that the large luxury saloon from Affalterbach in provincial Swabia would be able to keep up with the well-established teams.
5th place in the starting line-up for AMG
The AMG racing saloon was technically based on the Mercedes-Benz 300 SEL 6.3. With an engine output of 184 kW (250 hp) at 4000 rpm and a top speed of 220 km/h, this luxury saloon was Germany’s fastest regular production car at the time. It was not only an enlarged displacement from 6330 to 6835 cc that increased the output to 315 kW (428 hp) at 5500 rpm, and torque from 500 to 608 newton metres. AMG co-founder Erhard Melcher “tweaked” the eight-cylinder power unit using classic methods: high-precision camshafts and modified rocker arms, lighter connecting rods, new Mahle pistons, larger intake valves, modified combustion chambers, polished intake and exhaust ducts, a new intake tract with two throttle flaps and a racing exhaust system ensured a better gas throughflow and made higher engine speeds possible. Endurance was improved by installing an additional oil cooler and finely balancing the crankshaft.
The wings were flared to make room for the lightweight size 10 x 15 and 12 x 15-inch magnesium wheels adopted from a C 111 test car. Aluminium doors helped to reduce the car’s weight from the original 1830 to 1635 kilograms. Larger front wishbones, a more robust rear axle with a heavy-duty differential and smaller, stiffer suspension air bellows made the saloon fit for the racetrack.
Spectacular S 63 AMG”Thirty-Five” showcar in the style of the racing touring car
Like its historic predecessor, the new S 63 AMG showcar does not fail to attract attention. Eye-catching details include the imposing tyre sizes of 275/35 R 20 and 325/30 R 20 at the front/rear, and the 4.5 cm flare on each wing. The start number 35 and practically all the sponsoring stickers follow the original. Instead of fire-red non-metallic paintwork, the body of the showcar is finished in “AMG Le Mans red metallic”, a colour available exclusively for the new SLS AMG. The functional interior is enhanced with black/carbon-fibre piano lacquer trim. A rollover cage, two AMG sports bucket seats with four-point seat belts and an AMG sports steering wheel lined in leather/Alcantara underline the racing touring car look. This spectacular showcar provides an outlook on the series production version of the new S 63 AMG, which is due to be launched in September 2010.
