Toyota Sai Specs, Engines & Dimensions (2009–2017) — First Generation
The first-generation Toyota Sai brings hybrid power to a conventional sedan. If your daily journeys mix city traffic with faster roads, its powertrain’s behaviour is worth understanding before you choose one.
In the 2.4 CVT, the Toyota Sai engine works with an electric motor to drive the front wheels. The variable transmission accelerates without conventional gear changes, while hybrid assistance can save petrol in stop-start traffic. Under harder acceleration, you may hear sustained engine revs as road speed builds.
