At 41 mph the ICE kicks...but...

A little trick you can do on a downhill coast is to pop it into neutral at 40 mph and ride the coast down...

This accomplishes two things...

1. SGII reports max mpg by going from EV mode into neutral coast before 41 mpg.
2. Neutral coast gives you max roll on the downhill

If you go from EV mode to ICE to neutral coast SGII will report around 200 mpg. So going from EV mode to neutral before 41 mpg gives you max mpg and max roll on the downhill.

Note: Neutral coast is not recommended beyond 60 mph as the engine could potentially overspin. In heavy downhill cases brakes must be used while in neutral coast to avoid approaching the danger zone for speed on neutral coast.
