looking for something else tonight, came across this little gem.

Toyota TE-Spyder 800 PHV - shown at Tokyo Auto Salon 2014 (apparently)

Specs here .

Odd choice of powertrain - not that it’s a hybrid, but rather that they used the 1NZ-FE (like, a Yaris engine) with the Gen 3 Prius transmission. Is the NZ engine that much lighter, that it’s worth going to all that effort, when you could just advance the intake cam on the 2ZR-FXE and get similar power?

I didn’t even know that that combo would bolt up, to be honest, but apparently going the other way (putting a 2ZR motor in a Yaris) actually works , so they do have the same bellhousing pattern...

And then, I wonder how a sporty car would drive with the e-CVT. (I’m not even necessarily saying it’ll be bad, just I wonder how it’ll drive.)

thank you for that.

The 1NZ-FE is used in the Yaris Hybrid, right? So maybe the prius and yaris share the same e-CVT unit.

Toyota, why you do this to me?

It’s the 1NZ-FXE in the Yaris Hybrid and Aqua/Prius c (same platform, but longer and lower), but that’s just an Atkinson cycle version of the 1NZ-FE.

They don’t share the same e-CVT though - the Gen 3 Prius uses the P410 transaxle, whereas the Yaris Hybrid and Aqua/Prius c use the P510, a smaller version of a similar design (they did do some new things to the motor windings though, to improve durability):

Left is the P410, right is the P510.

they’re sadistic.

Your knowledge of things Hybrid and Toyota keeps amazing me, haha.

Comparing the drawings it indeed seems that the bellhousing patterns and input shafts match. Maybe the concept is using the 1NZ-FXE in combination with the P410, because that has a longer distance between the diff and the inputshaft, making it more usable in the MR design of the concept.

It’s the Otto cycle 1NZ-FE, not the Atkinson cycle 1NZ-FXE, that they’re using. Weight and packaging are really the only reasons I can see to use the 1NZ-FE over the 2ZR-FXE - torque is similar, and power would be similar if you raised the rev limiter on the 2ZR-FXE.

As far as using the P410 over the P510, that’s easy enough. Power. The P410 has bigger electric motors, and therefore can handle more power. And, they’re probably using the PHV version of the P410, which has taller gearing, and can therefore shut the engine off at higher speed.

For some reason I figured they’d probably used the atkinson cycle variant, but that thought was probably based on me thinking it was just the Yaris/Prius C drivetrain, silly me.

Using the more powerful and taller geared e-CVT indeed makes a lot of sense.
