I never fell in love with the N52. It's a good motor, technologically advanced, and does everything really well. Low emissions, fuel consumption, and broad torque. But it lacked the crispness (Valvetronic probably) and throaty nature of the M54. Never sounded as thrilling either.

I do like the shift towards turbo 4 cylinders. The Opel Insignia I drove with the 2 litre turbo had serious punch and torque, yet was docile and smooth when driven lightly, with just a hint of whistle if you listen for it. Too bad the Insignia is so heavy- the fuel consumption takes a bit of a hit.
