Cultus HP/rpm=55/5800
Alto HP/rpm=55/5500
Cultus torque (kg-m/rpm)=8.5/3000
Alto torque (kg-m/rpm)=8.5/2500
Engine of Cultus has long gear ratios, more top speed, noisy engine and more fuel consumption
Engine of Alto has short gear ratios, less top speed, more torque, less noisy engine and a little better consumption
4 cyl make Alto engine a little smooth and due to the short ratio gear box the engine feels more tight to rev. up... and that leads to less top speed
