y is a dbs slower than its older sister the db9

Its not the DBS has 380kw as the DB9 has 350kw, also the DBS has a top speed of 307 and the DB9 only 300. so i think you are mistaken.

The DBS IS faster the DB9. What crack u on man

actually the new db9 has the same top speed as the dbs, but the dbs has better handling and suspension. in terms of 0-60, i think pretty much all the Aston coupes can get from 0-60 in around 4.2

the vanquish is faster than the dbs. which is rather sad.

who cares how fast it is, the design that went into it is what makes the car

The DBS is just a lighter version of the DB9. But i would choose a DBS over a DB9 anyday.

dbs is all round faster than the db9... if there is indeed a new db9 ders gonna b a new dbs AND there is no way a normal vanquish can b faster than a dbs.... its da Vanquish S das quick...but the Vanqish S want built wel... ders an episode of fifth gear wer its put under hard accelaration under full steering lock and the cam belf kept cumn off. cumon!!

i think dbs is faster on the other hand. it gives more power than db9. http://www.aston-martin-dbs.com/martin-dbs-images-gallery/

Get a Vantage S if want speed and handling. Much lighter with a racing chassis.
