X6 35i VS X6 35d. What should I choose?

[Arslanoff]

X6 xDrive35i - 335i, making 306 horsepower between 5,800rpm and 6250rpm, and a peak torque of 400Nm between 1,400rpm and 5.000rpm;
Cons (l/100km): 14,9 / 8,6 / 10,9; Emission 262; 0–62mph 6.7 Seconds
Price 56.800,–

X6 xDrive35d making 286 horsepower and a peak torque of 580Nm; cons(l/100km): 10,5 / 7,1 / 8,3; Emission 220; 0–62mph - 6.9 Seconds; Price 61.800,–

Everything else is looking the same.

1) I live in Germany, and Diesel car taxes are twice higher here, but I very like torque and low fuel cons rates for diesel, it is worth driving diesel if you drive more then 15000 km/year (I drive about that)
2) X6 xDrive35i is cheaper
3) 0-100 km/sec are almost the same
4) I don't like the diesel engine sound

What should I order, what do you think?
