Question : In this article, if I understand right, Clarkson says that the 135i has sequentials turbos, but in the article about the 335i, he says that there is one turbo for each row of cylindres (non-sequential). Is it right or is there a mistake ? I thought it was exactly the same engine ?
Text about the 135i: "
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 . . . in bigger and bigger lumps."

Text about the 335i: "
What you get instead is a 3 litre straight six, which is force-fed its diet of air by two small turbochargers. On paper this sounds fine. Because they’re small, they don’t take an age to reach operating speed, which means there’s no turbo lag. But because each one is feeding only three cylinders, you still have loads of power and loads of torque."
