"we expect positive quarterly free cash flow, with possible temporary exceptions, particularly around the launch and ramp of new products. We believe our business has grown to the point of being self-funding. We continue to aim for positive GAAP net income in Q3 and the following quarters, although continuous volume growth, capacity expansion and cash generation will remain the main focus. Our 2019 capex is expected to be about $1.5 to $2.0 billion, a reduction from prior guidance. We continue to find opportunities to improve capital efficiency and shift cash outflows to future periods. This estimate includes the development of our main projects, on the timelines referenced, and to expand our Supercharger and service networks."
