We had already noticed that the Prius III had a very optimistic speedometer, and the same is true here with the Plug-In version, to the point where it is strikingly obvious in traffic. After checking tire pressure, we measured, swiss chronometer in hand, a significant mismatch between the vacuum fluorescent display and reality: 90 km/h at an indicated 100, from 107 to 110 at an indicated 120, 113 at 130 km/h, etc … Our measurements systematically show that displayed speed is grossly exaggerated. Even more peculiar, the odometer is quite precise when compared with google maps. Would Toyota try to protect its customers from speeding tickets ? Or entice them to save fuel by enticing them to drive slower than they think ?

Equipped in Sol Premium trim, the Prius 3 Plug-In is an enjoyable car to live with, easy to manoeuver once you factor in its mediocre turning radius (11.2m according to the spec sheet). There is a wealth of storage compartments, one of which is dedicated to the charging cable. Suspension is comfortable, but with spring rates which are not excessively soft. Indulging into spirited driving attempts will quickly confirm that the 65-series tires lack rigidity and translate into predictable understeer. On freeways, the car offers good stability and is more relaxing than a Prius II to drive on long distances. The electrically assisted steering column is light but numb, not too surprising for the target audience.

The Toyota Prius Plug-In is without doubt a polished product which builds on the unmatched technological experience of the Toyota group over time and volume, but this expertise comes at a steep price for a car that is more of a super hybrid than a real electric car. Competition offers more in terms of an electric car experience, both in terms of range and torque, at equivalent prices. If price is no object, then the plug-in version is without doubt a better Prius, but for people in the market for a car delivering on the promise of an electric car experience, the Opel Ampera represents serious competition.
