Hi,
I have the 2011 model with CVT and I'm using an OBD scanner with "torque" app to monitor the engine, mainly for fun. I noticed a strange behaviour:
When I put my foot of the gas pedal, the car naturaly starts to slow down. In this case I see 2 possible scenarios.
1.) if the speed is above 80km/h, both torque and onboard computer show 0l/100km. this is expected and ok.
2.) if the speed is below 80km/h, the onboard computer shows 0 (no bar shown), while torque shows ~2l/100km.
Another interesting fact is that if I downshift and raise the rpm to say 4000, this consumption goes up (3-4l/100km). I would understand why if this was an old carburettor based engine, but of course it isn’t
Anybody else playing with tools like this and noticing any strange behaviour like this?
Regards,
Klement
fuel consumption while braking with engine
I find the reported values unlikely... It is probably just poor programing on the feed back. It should consume close to zero on a downshift.
I think it shouldn't. Since the engine is being moved by external source of power (wheels and the cars inertia), all other systems that get power from it can continue to do so. No need to add fuel, there is no way for the engine to stutter or shutdown while the car is moving faster than some small (5?10?kmh) speed.

Which bluetooth adapter were you using? I just ordered the super mini one from amazon ill post my results when i get it
All modern cars have DFCO(deceleration fuel cut-off). When you are off the throttle, and the RPMS are above idle, the fuel injectors cut off all fuel.
