Well,other than the fanciful figure, it's not as good or just
merely match the performance that of legendary German
sportcars.
For instance,i do recall that a close circuit test of a 1000hp
GTR in Japan netted a top speed of 333km/h.
However, a stock BMW M5 or M6 (with only half that horsepower)
de-limited can already hit
that speed easily.
Anyway, spotted this near the Flyer yesterday.
