Re: 156 2.4 vs 159 2.4
I had a BMW 320d and it was amazing in terms of economy and power. They have an almost complete package. If they had employed an Italian instead of a partially sighted Yank to design their cars the story would be much different.
The thing is though that BMW get the power and the economy and emissions etc through the combination of excellent engines, drivetrain, gearbox, transmission, etc. It's not just the engines, plus the rear wheel drive means thy make better use of power as the front wheels only do the steering. It makes a big difference in handling, feel, and obviously performance.
