Electric car tax credit replaces quarterly estimated payments?

In April I sent the first of what I anticipated would be 3 quarterly estimated tax payments to the I RS.  Subsequently we purchased an electrIc VW and the dealer submitted an application for the $7500 tax credit to the IRS.  Am I correct in assuming the the electric car tax credit (totaling 3X what the estimated payments would have been) would mean that I don't have to submit any morel estimated payments this year?
