Strigear components compared to conventional vehicle
When compared to a conventional automatic transmission (AT) vehicle, Strigear require some additional components, basically two electrical motors, power electronics and a battery pack. However, the IC engine can be much less powerful. The maximum engine power can be reduced by 50% and still permitting slightly improved acceleration. A Strigear hybrid can obtain superior fuel consumption using a small, simple gasoline engine while modern fuel efficient conventional cars use much more expensive engine technology. The gearbox is also considerably less complicated, as the electric motors handle all synchronization. The cost reduction on engine and gear box cover a substantial part of the cost required for electric motors, inverters and batteries. It is quite possible that the cost reduction in mechanical components will cancel out the increased costs for the required electric components within a couple of years. (Primarily due to higher volumes of electric components for automotive use and also as prices for electronic components can be expected to fall much faster than prices for mechanical components.)Strigear components compared to Toyota Prius
When compared to a hybrid as Toyota Prius, both systems require components with similar complexity and performance:
- A Strigear Prius look-alike requires two electric motors (140 + 140 Nm), power electronics, some 24 kg of battery cells and an actuator controlled simple manual gearbox.
- Toyota Prius II has two electric motors (31 + 400 Nm), power electronics, 39 kg battery cells and a planetary gear.
