Are my capital gains going to be taxed at 15% or 25%? And is that tax able to be deducted with the purchase of an Electric Vehicle or not?

I sold my rental property and have a $76,000 capital gain (even though I actually used that money to pay back my parents for the down payment on my current home). I was wondering if the tax I owe on capital gains is deductible with the Electric Vehicle purchase (tax deduction). The Pacifica Hybrid qualifies for a $7,500 deduction, but I don't want to buy it if it will not HELP reduce my taxes. Thank you!
