I didn't realise the Ultima boasts such spectacular performance stats.
There seems to be a good market for these ultra fast go-karts that come in under the silly prices of the likes of the SLR and porsche gt.
But back to fastest production car, i mention the callaway not only because of its 0-100 time but also its top speed of something to the extent of 405. Because they placed a set of race tyres on for safety and performance does not detract from the fact it is a production vehicle. Does a sprinter who runs 9.78 for the 100 wearing a pair of running spikes not get the title of fastest man in the world, should the fastest man be one who runs in no shoes???
And should they be forced to check the high speed on a main road not a race track??
It is not illegal to drive on a road with what amounts to race bread tyres. However, comfort,cost and safety generally means most cars don't.
