Yes, thank you. I was wondering if you can comment about whether you felt that Q2 benefited from consumers in the US sort of rushing out to buy Model 3 in advance of the declining federal tax credit, a phenomena that you sort of saw in Q4? And part of the reason I ask is, at least by my analysis, it looks like maybe 70% of the Model 3 sold in the quarter were in the US, which is sort of higher than your normalized percentage of US sales. And so do you feel that, that phenomena may have occurred in Q2? And are you still confident that Q3 deliveries can improve sequentially? And beyond the data point that you provided on the call that the orders quarter data better than last quarter, is there anything else you can point to that provides that confidence?
Elon Musk -- Chief Executive Officer
Yeah. I think we'll -- demand in Q3 will exceed Q2. It has thus far and I think we'll see some acceleration of that. So -- and then I think Q4 will be, I think very strong. So we expect that quarter-over-quarter improvements. I think Q1 next year will be tough. I think Q3 or 4 will be good, Q1 will be tough. Q2 will be not as bad, but still tough. And then I see like Q3 and Q4 next year will be incredible.

Yes, just to add on the tax credit step down, so the step down from Q2 to Q3 was significantly lower than the step down from Q4 to Q1. It's also important to keep in mind that there's seasonality in the auto business in Q1, which also is part of the impact. But generally speaking, our order rates so far this quarter is higher than where we were at this point in Q2, and we haven't seen a significant impact on US-based orders as a result of the step down.
