Rolf Mellde (1922 – March 2009) was an engineer who specialized in performance engines and also a

car racing
enthusiast.

Early life

Mellde's grandfather

turbo compressors and diesel engines
at the age of ten.

After finishing his basic education, Mellde studied

two stroke
boat engines.

Work at Saab

Mellde started working at SAAB in September 1946 and was put in charge of engine development.

In 1948, he started his competition career in a

Skarpnäck. When he became head of testing, he suggested that SAAB participate in automotive competitions to show off SAAB's engines. In 1950, SAAB entered the Rikspokalen
and won. SAAB won eight times up to the final Rikspokalen in 1961.

In the 1960s it became harder to sell

four stroke engine. They had tested several four strokers and the one that was best was the Ford V4. the board were invited to drive a test car but none of them wanted to. Tryggve Holm even thought the idea of a SAAB with a Ford engine was absurd. Lars Brising refused to state his opinion. The Saab management instead wanted him to continue working with the Saab 99
.

Having no luck, Mellde talked with Marc Wallenberg who used to drive a Saab 92. Marc talked with his father and Rolf got the go ahead with the V4 engine. Even before the go ahead, Rolf had secretly visited Ford in Detroit and asked both Don Fray, then head of Ford US, and Fray contacted Robert McNamara, head of Ford, and he had nothing against selling the engine to Saab. The price would be the same Ford charged their own daughter companies.

The switch to the V4 was done under great secrecy. Just before the factory closed for the summer in 1966, a number of workers were asked if they were willing to work on some 96s that had "faulty brakes". 40 workers volunteered and then Svante Holm explained that the real reason was that they would take the unsold cars and refit them with V4 engines. 600 cars were rebuilt and the V4 Saabs became a big hit and outsold the two-strokers by a factor of three.

Work at Volvo

Shortly after,

concept cars displayed at motor shows around the world in 1983. The car featured a very light diesel engine with direct fuel injection that gave very good fuel efficiency
, as high as 33.3 kilometres per litre (94 mpg‑imp; 78 mpg‑US).

Later life

Mellde died in March 2009 at 86 years of age.[1]
