The GTE *used* to be a good company car choice if you wanted to keep costs down.
Its not any more since they changed the taxation regime for company cars - basically you pay income tax on the monthly payment OR the CO2 tax, whichever is the higher.
Only fully electric get you any tax advantage (at the moment).
A guy a my work used to have a Mk7 GTE, even he decided it was a poor choice back when it was a cheap choice. Poor electric range, no real performance and "self charging" mode drank fuel like it had a 2 inch hole in the bottom of the fuel tank.
Hybrid...meh
