Geely introduced a 1.4T engine in 2017

There have been some reports saying that Geely in China has been using old technology retired engines in its new models these past few years. Well, because information coming from China can sometimes be a little scarce or limited, the news is not always all very true.

We have just found out that Geely’s 1.4-liter turbocharged engine from 2017 was completely developed in-house and it also won an ‘engine of the year’ award. This award winning engine could be used in the coming 2021 lineup of the Saga, Iris and even Persona all new replacements.
