Original sentence: However, Honda's Integrated Motor Assist uses a more traditional ICE and transmission where the flywheel is replaced with an electric motor: it is a simple parallel architecture, requiring the addition of a mechanical continuously variable transmission.Toyota's Hybrid Synergy Drive is similar in that it also combines the power from a  Internal combustion engine (ICE) and a pair of electric motor-generators; although in its original form, it uses only one planetary gearset (input split only) in a series/parallel architecture
Edited sentence: While Toyota's Hybrid Synergy Drive may appear similar in that it also combines the power from a  Internal combustion engine (ICE) and a pair of electric motor-generators; in its original form, it uses only one planetary gearset providing only 1-mode (i.While, Honda's Integrated Motor Assist uses a traditional ICE and transmission where the flywheel is replaced with an electric motor: it is a simple parallel architecture, requiring the addition of a mechanical continuously variable transmission.input split only)using a series/parallel architecture.not electricaly variable)
