Peter got my attention right away. I'll look at the VW TDI AWD wagon if it's ever released.
Looking for one vehicle with great fuel economy, AWD, tow capable and International standard trailer lighting capable. Unfortunately Audi USA is very slow at getting the 2.0TDI engine into their Allroad, which has been very popular in Europe. Believe the 2.0TDI is only in FWD A3s. Incidentally the A3 will tow single seaters well.
The VW Tiguan TDI is unavailable in USA.
So is the Subaru Forrester TDI.
And of course Audi Allroad TDI.
All are available and used for towing gliders elsewhere.

I know a few people here in NZ who have Korean SsangYong Rexton W SUVs with 137 kW (184 hp) Mercedes 2.7l turbo diesel engines and transmissions. I've driven one and ridden in a couple of others. They're no Audi, but they're roomy and comfortable, good power and acceleration, very good fuel economy, tow well (recommended maximum 7000 lb, 3200 kg). And cheap at NZ$48k (US$36k) with AWD
or NZ$40k (US$30k) with part time 4WD.
