Depending on who you talk to on the defintion of drifting, some would say that front wheel drive cars can't even drift (one defination is that you accelerate so hard that the rear tires break loose, which would be near impossible on fwd).

The simplest way is to pull the e-brake. There's also ways to build up your suspension so that your car tends to oversteer instead of understeer (sway bars, shock stiffness, even tire pressures). Then it's just a matter of turning hard, hitting the brakes so that the rear lifts even more, and the back comes sliding.

You can also use your surroundings. Puddles, dirt, ice and snow patches make the rear have less traction if you can aim it so that only the rear wheels land on that stuff.

If you're going to try any of this, make sure you're in a wide open space away from trees, curbs and small children.
