bikes do it now with but a tiny patch of rubber on the road. the key is low weight, much of it on the back under acceleration, and lots of low-end torque. on the bikes the last part is accomplished with gearing and a multiplate clutch that can survive being slipped at full power for a while. this allows a high-rpm (=power -> torgue) launch without spinning the tire. if you tried that in a typical car the clutch would be toast in one run, plus you'd need a locked diff or the new M diff to avoid smoking just one of the tires. if someone does a car light enough and/or with strong enough clutch and/or enough low end grunt, it will happen. there is a lotus 23 replica being sold in san diego with a 240hp supercharged motor (about 1100 lb car)... wonder how that does? ;)
