I would hope one of the requirements to be a "street-legal" car is that it can turn, at the very least...
If we make a horrendous assumption of constant acceleration we can get a maximum on it's 0-60 time:
s=1/2 at^2, t=9.87s, s=400m gives a=8.21 m/s^2
60mph = 60*1600/3600 m/s= 26.67 m/s
t60 = 26.67/8.21 = 3.25 seconds.
So we can conservatively conclude this vehicle does 0-60 in under 3.25 seconds.
Someone with better knowledge of the acceleration/velocity curves of cars can probably correct me on this, but I'm assuming that acceleration reduces with velocity rather than increases, due to wind resistance etc. If this is right 3.25 should be considered a maximum - if the acceleration reduces above 60mph, say, then the car must accelerate to this velocity in even less time to get a quarter mile in 9.87s.
From the data given we can only conclude that its top speed is somewhat higher than 400m/9.87s = about 40m/s or 90mph, but of course that would assume instant acceleration to 90, in all likelihood its top speed is far higher.
