It's not often we do the InsideEVs 70 mph range test on a plug-in hybrid, but make no mistake, the 2023 Toyota Prius Prime is no ordinary plug-in hybrid. So when we were presented the opportunity to attempt to see how far the totally redesigned new Prius Prime would go at 70 miles per hour on a full charge before the gasoline engine turned on, we jumped on it.
The range test happened at Toyota's first-drive event for the 2023 Prius Prime in Carlsbad, California, on a chilly, rainy afternoon. We typically cannot do range testing at media events like this, because the automakers have planned out routes for us to take, but we were able to pull this one off without causing any issues with our hosts for the event.
