- The Toyota Prius Prime and other plug-in hybrids are sluggish in EV mode in our acceleration tests.
- PHEVs are heavier than regular hybrids and have electric motors that are not as powerful as those of pure EVs, making it difficult for them to reach 60 mph on electric power alone.
- In electric-only mode, the Prius Prime and other PHEVs took nearly twice as long to accelerate to 60 mph.
