Ewert has clearly developed an interesting product...and I'd be surprised if they engineered it to "fail" within the Prius engine system. They obviously intend to mass market the software/technology so it must have some sort of override that safely operates the vehicle.
But, I'd just be interested to read how it effects the Prius engine and what safety precautions it takes in regards to the engine and inverter. The fact that they install a larger battery to run the system says alot up front...they recognized the amount of amps to run that high of a speed required much more energy from the battery (like more than 3x more than the stock Prius battery). That being said, the inverter temps have to be addressed somewhere along the way.
If anyone has more info I'd love to see it...cost looks to be around $2k...not bad to get extended periods of highway driving gas free.
