Heather Willis is the vehicle specialist for the 2016 Toyota Prius models. Willis wants to talk all about the double wishbone suspension that makes the Prius so much more fun to drive, but there is more than one Prius, and sometimes that can be confusing.

There are six models – all models use 1.8-Liter 4-cylinder aluminum block and head, double overhead cam (DOHC) 16-valve VVT-i. There is only one Prius that still uses the Nickel-Metal Hydride battery. Why?
