A rule of thumb is that 10 awg wire drops .1 volts over 1 foot at 100 amps. Most drive trains don't draw 100 amps for normal driving. If you assume 40 amps and a 1 foot different, that's .04 volts dropped or 0.3% of 12 volts. It would be worse if smaller wire is used (eg 12 awg), there is a longer length mismatch, or you have a particularly inefficient or high current drivetrain.
