It's so lame that they try to market a regular 320d as 328d and a 530d as 535d in the US.
If people judge a car by the number glued on its trunk lid they better don't buy a BMW.
Actual Bi-Turbo *35d makes 313PS and 465 lb/ft. That *30d is not weak by any means, a wonderful machine but it's not a *35d.
Why all that trickery
