We test drove an XC90R and the XC70 T6, the T6 was buttery smooth, faster, and more refined. Completely outclassed the XC90. Initially the auto trans. was jerky at times and sometimes shifted sluggishly, but after 3 months, we didn't notice it at all, completely smooth. Mileage in the beginning averaged close to 13L/100km, but now is close to 10.5, after 17,000 Km's, and getting better. This is a very solidly built car, tough, comfortable, builds confidence.I can stand up after 9 hrs driving and feel no back pain! Great winter car, with full winter tires, confidently passed many lines of tailgaters on snow covered highway. Reliable, not one issue to date! AWD engages effortlessly, Ex. in snow
