The MPG was the other deciding factor. My commute is 75mi per day so my XC90 V8 as much as I love that thing would get 18mpg in the winter aorund 20 in the summer, so roughly 4 gallons of fuel per day or at today's rates about 10$.
The Q7 has been holding consistently 30mpg for me which may not seem like a huge deal but it does add up. The other thing I really like about the TDI vs a V8 is that torque you get early on which makes this 5500lb vehicle feel a lot lighter and quicker. The V8 you had to really get on it to get it to go.
Not shillin’ here for them, but on a “hey, it’s just $12” kind of whim, I bought some Hotshots Secret Diesel Extreme and put 10oz in the tank. The bottles are leaky and the stuff staaaanks. BUT! My mpg improved - no joke - average 8mpg for both city and highway driving. I’d been monitoring it closely since I got the 2011 Q7 TDI last month to get a sense of things. I was getting about 16mpg city and 22 highway. Now I’m at 21 city and 32! Highway. I drove 50 miles the day I put it in, and the “miles to refuel” remained at 540mi all day. That was Monday. The efficiency has stayed the same so far.
Anyway, I was astonished; you might give it a shot. I didn’t notice any harder pulls or anything (we already have 400ft-lbs of torque), but this morning the “miles to refuel” indicator ticked to 535mi, and that’s with 100% city driving today and yesterday. Just my recent experience. I got the TDI for the same reasons as you.
