They vary a bit... One of the big keys is compression ratio: The higher it is, the better the MPG & power. Thats how Mazda beats the VW Passat 1.8T in MPG & power both. ... Another important factor is number of transmission gear ratios, 6-speed OK, 8-speed is better, CVT is great. And of course the weight & aero drag, although 'most' of the cars I chose for the list are in the same category of weight range. Other engineering quality feats of technological prowess come in the area of clever engine computer control software algorithms used. Bottom line, the car maker that can deliver the most power for great MPG wins.
