It can't be worse than 32 pts and BMW 5-series has topped that!
Note that Corsa's seats perform twice better (in terms of points) than Astra's..
So why doesn't Opel install Corsa seats in Astra?
Here is the link to a pdf file from Thatcham.org. Read more about the whiplash test and results over here:

And would you note that Honda has good points only in the New Civic and the rest are poor...
Also noteworthy is, Porsche refused to take part in the tests like some other makers...
