Perhaps no other decade has contributed to the development of the truck than the 1950s, despite the fact that truck design had changed relatively little.
Petrol engines and rudimentary pre-chamber-combustion diesel engines were superseded by efficient direct-injection diesel engines. Volvo acted as a pioneer of the turbocharged engine and the emergence of stronger, more efficient engines contributed to heavier and longer truck combinations.
The introduction of sleeper cabs and power-assisted steering made life easier for the driver and as a whole the importance of truck transportation increased.
Now get into the diesel-injected innovations of the Volvo trucks of the '50s.
