The OP is right that 8 sec 1/4 is extremely impressive, but he is wrong that there are few production cars that can run 8s. No production car runs anything close.

The fastest 1/4 mile production cars are supercars such as the Veyron and 918, which are at or just under a 10seconds.

Remember, an increase from 20->18 seconds is roughly a 10% increase in acceleration; 10->8 is roughly 20% increase over an already ludicrously fast million-dollar supercar.

It's frankly ridiculously fast.

True. GTRs are not the best for drag racing. I think the Alpha 12 (~1200 HP) GTRs are actually dipping into the 8's, but I was thinking more along the lines of a Mustang, which is one of the most common cars used for drag racing and is usually much lighter.

Many cars in the 1200 HP range are much faster, such as the "Red Demon" DSM which is somewhere in the 7 second range.
