  Inventions
  According to Forbes magazine, Mannheim is known for its exceptional inventive power and was ranked 11th among the Top 15 of the most inventive cities worldwide.
  Many significant inventions were made in Mannheim:
  Karl Drais built the first two-wheeled draisine in 1817.
  Karl Benz drove the first automobile on the streets of Mannheim in 1886. At his workshop in Mannheim, he produced a lightweight three-wheeled vehicle powered by a single cylinder petrol/gasoline-fueled engine, first shown in public during 1886. This powered tricycle subsequently came to be widely regarded as the first automobile/motor car powered by an internal combustion engine. Karl's wife Bertha Benz undertook the world's first road trip by automobile from Mannheim to Pforzheim and back, about 65 miles then, on modern roads about 55 miles, in August 1888.
  The Lanz Bulldog, a popular tractor with a rugged, simple Diesel engine was introduced in 1921.
