Calibrated for high mileage, the Drive mode allows the engine to run at very low rpm while cruising, which sometimes produces a slight vibration.

Electric motors are most potent from zero rpm, so most of the acceleration, delivered via a single - speed auto transmission, is in the first 30mph, though BMW does claim that the engine changes enhance acceleration at higher road speeds, too.

Because the A / C load is so high, modern computer controlled cars delay the A / C clutch engagement until the engine gets a rpm bump up.

The problem appears to be between IMRC Terminal 1 and PCM Pin 42, which is now permanently closed irrespective of engine RPM when it should be in a different state if RPMs are less than 3,300 and in another state if RPMs are higher than 3,300.

For example, at the red light when idling and without touching the gas pedal, the engine in some cases starts «hunting», oscillating between the usual minimum rpm and an higher value like I was giving rpetitive pushes to the pedal, or, more frequently, the engine start keeping a quite high rpm (I estimate 2000 - 3000 rpm), VERY constant, before dropping back to normal.

At 80 mph, the engine isn't spinning too high — around 2,400 rpm — and 20/26 mpg city / hwy fuel economy isn't terrible, but the very best you can expect from the 13.7 - gallon tank is around 350 miles, which led me to join contributor Marc Noordeloos in wishing for more range.
