Explains the great 0-60 time. 5.9 seconds
For example the Audi S3 did 0-62 in 5.5 seconds but it did have 265hp and is AWD so will not suffer any wheelspin off the line.
Nissan 350Z is similar weight and RWD and had 276hp to post a 5.9sec. 0-60mph, although is a manual. Can launch harder but perhaps a little slower through the gears.
So can well believe the 328i is pushing out a tad more than the claimed 245hp.
