The fiesta's first section of the owner's manual clearly states to SET YOUR ENGINE BY DRIVING AT NORMAL SPEEDS. Since this is a unique type of engine, the first 5000 miles are extremely important in the performance of the car from then on out. This simply means don't accelerate at extremely high speeds, don't drive extremely slow. It's that easy. The engine is a manual-automatic and needs to be set. All of the morons on here complaining about jerky transmission and slow acceleration obviously DIDN'T READ THE OWNER'S MANUAL. It's a great car if you treat it right. At least 38 MPG and it has been very reliable so far. AWESOME.
The manual-automatic dual-clutch engine, SYNC, voice recognition, MPG, upgraded paint/seats, lights in the back seat, keyless entry.
Well, what you just said does not make sense, when at times you have to accelerate on and off ramps in busy cities, or are stuck in stop and go traffic in a busy city.. At which times the problems arise.... I am sure if your interpretation was realistic, it
might make sense.
