The Rorschach test of engines

What do you see?

A mushroom?

A Sailboat?

These are RPM / Speed correlation charts of different transmissions.
The first one is an e-CVT from an Auris Hybrid, while the second is a traditional one from a Renault Megane.
The e-CVT can attain every speed with several different RPM from the engine, while a traditional transmission has to choose between a discrete and limited set.

Diesel / Hybrid highway comparison

Here is the same road (85% highway) driven with an Auris 2013 Hybrid and a Renault Megane 1.8D

Auris:

Megane:

It's a somewhat uneven comparison, as the Megane held an higher speed, but it's interesting to note that the Auris mileage curve is still climbing after nearly 100 km.
Megane mileage curve instead has peaked and is going down.
The peak is related to a stop at a service station.
But why it suffers from that?
Maybe the sudden stop drops temperature?
Let's add coolant temperature to the same graph:
Auris:

Megane:

That doesn't seem to be the case: there's a drop in temperature, but it affects the Auris, not the Megane.
By the way we can observe that the diesel engine has a lower operating temperature than the HSD and the Auris reaches working temperature after nearly 20 km.

V13 released

News:

• SOC gained while coasting

• ICE off evaluation is now more accurate (engine spinning with no fuel is included)

V12 released

News:

• Prius 3 braking evaluation is now correct

Fuel flows

Fuel consumption of the 2 newer HSD engines, measured in fuel cc/minute at various engine RPMs.

Yaris, 1500 cc:

Auris, 1800cc:

Note that at 1000 RPM consumption seems to be just the same, but as the RPMs increases, Auris has a steeper curve.

Prius 3 MY 2012 brake analysis

Here is brake from a MY 2012 Prius 3, Regen Coop in yellow:

There are some differences from Yaris:

• base value of WCyl is 0.47058824 instead of 0.49019608
• WCyl seems to always increase when braking: on Yaris it doesn't seem to increase when only regenerative braking is in use.
• the value of WCyl when regeneration is active is 0.49019608, just the same as the base value of Yaris...
• regenerative braking turns of under 18km/h (I suspect the cut-off value is 12 as in other HSD cars).

V11 released

News:

• map aspect ratio should be correct now
• added RPM /fuel flow chart
• missing GPS data won't corrupt maps anymore
