I'm going to say, not impressed. My 10 year old 7,000# truck will bust those numbers all to pieces driving the same exact route at 65 MPH. I'm pretty sure my '13 will get those numbers under the same conditions. It just wouldn't do it when you add regenerations in but it does weigh in at 8,000# too. I'm impressed with that little motor making the power it does but not the fuel mileage.
