Horsepower is still measured the same way. The only difference is the conditions under which it is measured. Horsepower at the flywheel means that the engine was mounted on a stand, without a transmission, and bolted directly to the dynamometer. This gives you the horsepower of the engine. Rear-wheel horsepower is measured by putting the complete car on a rolling road dynomometer. This gives you the horsepower of the engine, minus the power used to run the alternator, transmission (could be as high as 17% for an automatic), power used up combating friction in the final drive (differential), rolling resistance of the wheel bearings, the tyres...the list goes on. So, the same car could be listed as having 200 hp, or 166 hp...go figure.
