Regardkess of specifications other similar vehicles like the BMW X5, VW T-Reg, Porsche Cayanne, and Mercedes ML have a proven track record for towing, when set up optimally. Turbo powerplants like you say have issues that sometimes do not work well for towing.
These offshore designed vehicles seem to have one thing in common and that is roadability (handling and tight suspension), which is a benefit when the vehicle is applied to towing duties. The other benefit of a vehicle like the Audi is that it is fun to drive when not towing which for most of us is most of the time.
It is impossible to know how any said vehicle will handle any said TT. To know exactly how one tows and feels you need to hook one up and go for a test drive.
Here is a blurb from one of the online reviews....
Audis Allroad Has Proved Itself As The Premier League All Terrain Estate. With a 4.2-Litre V8 Engine, It Puts Even More Distance Between Itself And The Rest. By Andy Enright
We all take it for granted that there arent too many sound, logical reasons for buying a huge 4x4. Theyre heavy, often dull to drive, can be a nightmare to manoeuvre through cities and they chug out more CO2 than most of us care to countenance. There has to be a better way. At least thats what
Audi thought when they launched the Allroad range of 4x4 estates.
After all, with many customers quite willing to part with over £50,000 for an upspec Mercedes M-class,
BMW X5, Range
Rover or
Porsche Cayenne, it makes sense to offer an equally well-appointed 4x4 estate to remind these high living larrikins that a more socially acceptable alternative does exist. Already available in either 180bhp 2.5 TDI guise or 250bhp twin-turbo petrol 2.7-litre V6 form, the Allroad has carved out a small niche for itself as the premier all terrain estate, above more modest pretenders such as the
Volvo XC70 and the
Subaru Forester.
