200,000 units delivered in the US (not world-wide) triggers the phaseout for a particular manufacturer.
The 2 quarters after the 200,000 limit is still full rebate, no limit on cars. Then 1 quarter of 1/2 rebate, no limit on cars, then 1 quarter of 1/4 rebate, no limit on cars.
So if Tesla rearranges production so that it hits the USA 200,000 limit on day 1 of the quarter, then that will be almost 3 full quarters of unlimited deliveries that qualify for the full credit.
Actually, it is as follows:
Full tax credit is available for one full quarter after the 200,000 is reached. For example, if Tesla's limit is reached in February 2018, cars delivered on or after July 1 will get half of the tax credit.
Half tax credit is in force for 2 quarters, ie. the rest of 2018.
One quarter tax credit is in force for 2 quarters, ie. the first half of 2019.
No credit for cars delivered on or after July 1, 2019 in this example.
