If we are taking nominations for new cars, I nominate the new for 2012 BMW 328/528. They have replaced the naturally aspirated 3.0 straight-6 with a 2.0 turbo 4. My dad and I test drove one a few days ago - very sluggish, lots of turbo lag, sounds like a cheap Honda civic, and gas mileage that is barely better than the turbo 3.0 straight 6 in the 335/535, and probably is no better than the engine it replaced.
