The two Honda models, the Civic and the CR-V, are produced in Swindon in southern England.
The vehicles where previously shipped to Malmö but from September they will be shipped on DFDS Tor Line vessels from Immingham in the UK to Gothenburg.
The higher departure frequency between the UK and Sweden was one of the reasons why Honda chose to change its port of entry.
Last year 320,000 vehicles were imported or exported through the Port of Gothenburg.
In terms of number, the Port of Gothenburg is the largest vehicle port in Sweden.
The makes that are now represented at the port are Volvo, Saab, Nissan, Subaru, Ford, Land Rover, Renault, Opel, Jaguar, Cadillac and Chevrolet.
