Glad to see that Clarkson liked the 135i, but he doesn't seem to understand how the turbos are setup:
But it’s the engine that impresses most of all. It has one small turbo to spin up the instant you apply the power, and then a bigger one that trundles into life later to keep the power coming
That's how the engine is setup on the 123d, but no so on the 135i. Clarkson is still a good read though.
