Which model tends to be more efficent in terms of Horsepower transfered to the wheels, front wheel drive or rear wheel drive. In other words, which platform loses more HP.

A very rough rule of thumb on drivetrain losses:
FWD: 10%
RWD: 15%
AWD: 20%
FWD: 10%
RWD: 15%
AWD: 20%

It depends on where the engine is, not just whetther FWD or RWD. RWD that has an engine in the middle (or the back) will loose the least power to the wheels. Also it depends on the orientation of the engine as some cars have the engine facing norths/south and some east/west.
Though, general rule is that the closer the engine to the driving wheels the better. Also having the driveshaft in the same orientation as the axel is benefitial.
