As an exercise I compared three cars Maruti 800, Maruti Alto Lxi, and Chery QQ
Maruti 800: 795cc; 37bhp@5000; 59Nm@2500; 650kg
Maruti Alto Lxi: 795cc; 47bhp@6200; 62Nm@3000; 740kg
Chery QQ: 812cc; 52bhp@6000; 70Nm@3500-4000; 880kg
Therefore,
Effy Values are…
Maruti 800: 0.8004
Maruti Alto Lxi: 0.8199
Chery QQ: 0.9189
What about the Torque value, how does it affect the efficiency? Does it mean lower the Torque lower the fuel consumption, And does it have to do anything with cars ability to run in difficult terrains, going up-hills...etc?
