AUTOart Mercedes-Benz SEC
At the Frankfurt International Motor Show IAA, in September 1981, models 380 SEC and 500 SEC were presented. They were coupe variants of series 126, succeeding the previous SLC models. In concept, the new coupé generation once again was based on the S-Class saloons and not, as their direct predecessor, on an SL model. A 6-cylinder variant analogous to the 280 SLC was not available. The V8-engines, already know in principal from the saloons and the SLC models, had been thoroughly redesigned within the Mercedes-Benz Energy Concept in order to reduce consumption and pollutants.
Introduced in 1990, the 560 SEC AMG was perhaps the most fabled of these pre-merger upgraded automobiles. The car was powered with a 6.0-liter engine, designed and built at Affalterbach using AMG custom quad-cam head with four valves per cylinder, producing twice the torque at half the engine speed of the original 5.6-liter Mercedes-Benz engine. On the outside, the car was fitted with distinctive AMG-designed front and rear fenders and door panels that allowed much wider wheels and tires to be fitted, inspiring the nickname Wide Body.
The AMG Mercedes-Benz 500 SEC was an extravagant attempt by AMG to outgun the opposition. After deciding the 190E Baby Benz they were using just wouldnt do, the mad German tuners elected to convert a giant ostentatious coupe into a hardcore track weapon. The end result was visually imposing, hilariously well-equipped and reasonably competitive.
