If I put a large down payment (over 50%) towards a car loan, can I reduce my interest rate and is it smart to even put that much down?
As others have already pointed out, the bank isn't getting your money upfront - the cash goes to the dealer and the bank will be financing you a much smaller amount. They really don't have any incentive to give you a better interest rate, but it never hurts to ask. The more important (and unasked) question is should you do this? Keeping in mind that a loan with good credit could be in the 1.8% range. Average long-term returns in the market are over 3x that, so by paying upfront you're trading the opportunity for 6%+ returns for the ability to save -2% fees.
