The genesis sedan might not smoke those cars but it would def be a close race either way.

09 sti's have about 300hp/tq and weigh about 3400lb. Genesis sedan make 375hp and almost 340ft/lbs tq, and hits full tq at 3500 rpms, and weighs 4000

So the genesis sedan would probably be a little slower, but still pretty quick! With intake/exhaust on could probably get up to 400hp...
