That’s not bad for a large car. I’m not getting that out of my 3 series.
For another reference, a drive to Swindon and back (200 miles) on an empty battery returned 75mpg, with essentially the Tiguan drivetrain (just older variant of it – smaller battery, and the predecessor of the 1.5 TSI, a 1.4). At slightly above 70mph plus a bit of city driving in Swindon and home town/journey to and from the motorway. While always having the full 250hp on tap if required (as was mentioned).
If i were you, i don’t know if you have a good VW dealership, ask for an extended test drive. Say, two-three hours (we had a 6 hour test drive with the GTE, just had to put a 5er of petrol in after). That’s enough to deplete the battery – just drive in E-mode until the battery is depleted (foot to the floor all the time drains it pretty quick, or motorway at 70mph electric only). Then see what it returns/how it feels on the petrol only.
My guess is, it’d be adequate. Quite obviously not a rocket ship, but 150hp and 250nm isn’t gonna be worse than the lower powered petrol Tiguan despite the weight increase. It’ll not be a road block, especially considering that the battery is still gonna “boost” under “heavy acceleration”. It just can’t hold speed on pure electric, you basically “sail” on the petrol engine. If that makes sense? It’s more intuitive actually using the system, not quite sure if i can convey how that works together.
