Though today the letters stand for power and performance, if you go back four decades, almost nobody had ever heard of a tuning garage called AMG. That was until the Mercedes-Benz tuner showed up at the 1971 running of the 24 Hours of Spa with... a luxury sedan. But not just any luxury sedan.
AMG took the 300 SEL 6.3, complete with wood dash and carpeted floors, bored it out to 6.8 liters and raised output up to 428 horsepower and 448 lb-ft of torque. With a top speed of 164 mph, the car qualified fifth out of sixty entries and went on to place first in its class and second overall, beating the likes of Niki Lauda and Hans Stuck. It was a pivotal moment that put AMG on the map.
Hans Heyer was one of the three drivers who alternated behind the wheel of the car dubbed the "Red Pig" that fateful day. And now forty years later, his son Kenneth Heyer is returning to Spa in a Mercedes-Benz SLS AMG GT3 in matching livery to the original. It's a trip down the memory lane of AMG's history – though not the first – reuniting one of its first race cars to its most recent, seven of which, all told, will be contesting the Belgian endurance race this weekend.
