Where I live, amongst the "environmentally concious" trustifarians (you know the type... those who claim to reduce their carbon footprint in one breath, then jet off to somewhere warm several times a winter), I see a few of each model every day, but still 2:1 T:S
Just got my wife the Q5 hybrid... 26 miles all-electric for her 2.4 mile round-trip commute. The only way to tell it's a hybrid is to look for a second fuel filler flap. "Free" charger, but $1,500.00 electrician install... Audi front-loaded the $7,500.00 tax credit and the dealer discounted a bit as well, so it was easier to accept the final price. Plus, it's quicker than the SQ5 and has the full tow pack, so there's an element of subtlety that I like.
