He had developed a sufficient reputation and income by 1970 to establish a studio with a major design team at Harkotten Castle near Sassenberg, Germany.
The studio was an enormous success, with work and exhibitions worldwide for many major companies.
Meanwhile, he continued with his innovations in car design, including his 1972 design of the Eifelland Formula One car.

This period saw him making his first forays into the Japanese market, when he obtained contracts from Japanese companies for the first time.
In 1973, he made his first study trip to the Far East, during which Japanese buyers recognized Colani's potential.
He received invitations by five companies to establish a Colani Design Center Japan.

About this time, the "Drop" teapot he designed for Rosenthal, a world leader in porcelain, was acquired for inclusion in the Cooper-Hewitt Museum in New York.
In 1999, Rosenthal promoted a special edition of his now-famous design.

Not all of his designs were successes.
For example, he created an unsuccessful design for an Olympic row boat.
About this time, in the early 1970s he developed his first streamlined truck design, which he said, "was a direct response to the world oil crisis yet nobody noticed my design.
They didn’t get the message."
He would revisit streamlined trucks later in the decade to more fanfare.

Colani's first profession as an aeronautics designer was revisited in 1976 when he was assigned the task of designing the  RFB Fanliner, the first plastic sports airplane with a Wankel rotary engine.
Later, in 1985, he unveiled the Pontresina propeller-driven airplane, having two contra-rotating coaxial pusher propellers with scimitar blades mounted in the tail.
The propellers, also known as "centripetal supersonic propellers", were a new design idea.
The plane was a design study and is not airworthy.

By 1978, his revolutionary trucks, aircraft, car and ship studies had begun to be seen frequently at exhibitions worldwide.
His interest in fuel economy continued into the 1980s.
In 1981, he set a fuel economy world record set with the four-seater Colani 2CV (based on the French Citroën 2CV which consumed just 1.7 litres of gasoline to travel 100 km using a stock 2CV engine and chassis.
