In city, mine is giving me 18.9 on A/C and 21.9 without A/C.
Also, I dont think there are any extra batteries for Eco Idle.
I think the regenerative braking means that the alternator is decoupled with the engine is now a dynamo with the tyres.

Also, the ES comes with an emergency repair kit and not a spare tyre.
Sadly, the repair kit components get taken out by the customs people at the port.
Does anyone have a repair kit that came with the car or is everyone getting spares made?
