The BMW 503 was a grand touring car produced by BMW from 1956 to 1959. It was designed by Albrecht von Goertz, who also designed the BMW 507, and it was intended to be a more luxurious and powerful alternative to the BMW 502 sedan.

The 503 was powered by a 3.2-liter V8 engine that produced 140 horsepower and 162 lb-ft of torque. The engine was mated to a four-speed manual transmission, or an optional three-speed automatic transmission, and it was capable of propelling the car to a top speed of around 118 mph (190 km/h).

The 503’s body was constructed of steel, with aluminum doors, hood, and trunk lid. The car featured a long, graceful hood and elegant lines that were typical of 1950s grand touring cars. The interior was also luxurious, with leather seats, wood trim, and a full complement of gauges and controls.

Despite its impressive performance and luxurious features, the 503 was not a commercial success for BMW. Only 413 examples were produced between 1956 and 1959, making it a rare and highly sought-after collector car today. Its rarity, combined with its stylish design and powerful V8 engine, has made it a favorite among car enthusiasts and collectors around the world.

Ok, let’s continue our classy BMW trip (I’m a BMW top fan by the way)

now we are going to introduce the most important part of our vehicle and the source of power in every car

BMW 503 engine

The BMW 503 was powered by a 3.2-liter V8 engine that was designed specifically for this car. The engine featured a cast-iron block and aluminum cylinder heads, and it was capable of producing 140 horsepower and 162 lb-ft of torque.

The engine was equipped with dual carburetors and a dual exhaust system, which helped to optimize its performance. It was also mated to a four-speed manual transmission, or an optional three-speed automatic transmission, which was a relatively new technology at the time.

The BMW 503’s V8 engine gave the car impressive performance for its era, with a top speed of around 118 mph (190 km/h) and a 0-60 mph (0-97 km/h) time of around 13 seconds. The engine’s smooth power delivery and refined operation also helped to make the car a comfortable and enjoyable grand touring car.

V8 engine was not as reliable as BMW had hoped, and it was prone to overheating and other issues. This, combined with the car’s high price and limited production, contributed to its relatively low sales and ultimate discontinuation after just a few years of production. Nonetheless, the 503’s V8 engine remains an interesting and significant chapter in BMW’s history of engineering and design.
