This study examines the research impact of gold open access (OA) journals in engineering and technology. A total of 37 gold route journals that request article processing charges (APC) and 66 other OA journals without APC (i.e., platinum OA) in the field were found in the Directory of Open Access Journals and used for the study. The publishers, APC charges, and the year each journal was added to DOAJ were identified and included in this study. An informetric approach was used to extract research impact indicators (citations, paper productivity, cite/paper, cite/journal, and h-index) of journals. Findings revealed that the publishers of the APC journals were dominated by commercial publishing companies, producing over 60% of the journals. Article processing charges ranged from $7.60 to $3,471.50, with an average of $727.00. Gold route open access (APC) journals performed better than open access non-APC OA journals, since they produced 51.2% of the papers, 71.8% of the total citations, and 65.1% of the total h-index. There was a weak positive correlation between the APC amount of the gold route journals and their research impact.
