Thanks for posting that Jimbo! I always thought the Prius combined HP was about 130 but according to this manual it is more like 170hp. Hybrid Component Locations & Descriptions (Continued) Specifications Gasoline Engine: 98 hp (73 kW), 1.8-liter Aluminum Alloy Engine Electric Motors 80 hp (60 kW), Permanent Magnet Motor
The electric motor can only add HP that the battery supplies, when it is using electricity that the engine supplies, that merely transfers HP, none is 'new' So the total is 134, although the PIP may be higher.
It's interesting that there were no symptoms other than the leak. The thread about the transaxle replacement is in the Gen II technical discussion forum LINK Transaxle Failure | PriusChat
