    Just for curiousity, I'm trying to figure out the engine runtime since the car was out of the manufacture. Tell me if my logic is sound.

    Using a previous trip data of 297.62 km (longest non stop with Hybrid Assistant running), where 38.24 km were done in EV, 47.18 were done without any fuel and 14.082 L of gas were used (according to Hybrid Assistant), I'll use the formula 14.082 / (297.62 - 47.18) * 100 and get the answer of 5.62 L/100 km for fuel consumption when the engine is running at highway speed (avg was 97 km/h for that trip).

    According to the odometer, for a distance of 142,944 km, the car obtained a consumption of 0.8 L/100 km. Using the formula 0.8/5.6 * 142,944, I get an engine run time of 20,240 km. Being a 2017 model, that turns out to roughly 3,500 km of engine runtime per year.

    Does my logic seems right or am I in the left field?

    Thanks.

    So, I'm the only one that's curious about how to approximate/find the engine runtime? That can't be...
