Volt and Honda ended with the same conclusion - once you're on US highway speed (130kmh+) you need direct engine to wheel connection.

The weakness of a series hybrid is when you’re on a highway at 75 mph—then an electric motor is not at its most efficient, but an internal combustion engine is. Pandikuthira said the Rogue package has been specifically tuned for the U.S. market. Where Qashqai “is set up for dense traffic conditions,” the Rogue package will be better tuned for the sort of highway driving Americans are used to.

Nissan publicly said their current ePower is weak on hills and sustained power - in EU uses 160HP 3 cyl 1.5T variable compression motor and in Latin America it uses 150HP NA engine.
Even UK people driving on flat highway said the sustained power derates to like 70-90HP.

The TFL guys might need to start doing this for hybrids and PHEVs.
This test is the about the same as Cypress Mountain from Highway 1 but at 100kmh.
Some numbers:
Time wise:
- RAV4 Hybrid/XTrail eHybrid batteries (~2kWh) would deplete in 1-2 minutes.
- RAV4 PHEV battery is large enough to complete the climt
Power wise:
- RAV4 and XTrail hybrid engines are just powerful enough to hold 100kmh. 100WHP is required, meaning 160 HP from N/A engine at elevation.
- Adding any aero drag like a roof box or any speed means the car will lose speed: 120WHP or 200HP N/A is required at 120kmh.
