Start&#x2F;Stop and Turbos are fine. I experience both in my 2012 Z4. That little turbo hardtop car is averaging over thirty miles per gallon for me while driving locally&#x2F;commuting and hit forty on a long distance trip. So all that mileage and fun, I will take it.<p>BMW is going to PHEV&#x2F;Hybrid all their cars within five to ten years so I expect we will get used to it. Far better option than lugging around eight hundred or more pounds of battery. Figure your going to end up with quite a few three cylinder engines and such until eventually replaced by some form of fuel cell and buffer battery.<p>I don&#x27;t think BMW is losing its handling prowess, I do think others are catching up and a few surpass them here and there; Jaguar is getting good marks.
