Simple point by point:
1 - Two cams for the engine. One is for normal city driving and other for high performance
2 - Engine runs on normal cam when the car is being driven while keeping the revs below 6200 rpm. The air intake and exhaust intake allow normal passage of air and fuel to make decent HP and vvt-i retards the timing of the valves to allow more low end torque while keeping HP at the minimum.
3 - Once the tacho needle swings pass 6200 rpm, the cam for normal performance gets replaced with a cam for high performance, which increases the lift of the cam lobe for both exhaust and air intake to allow more air and fuel to pass. As a result a lot more air and fuel is compressed into the cylinders (hence a compression ratio of 11:5:1) to squeeze out a lot more power that increases drastically till it hits the rev limiter at 8400 rpm. The effect is a sudden surge in power like a turbo charger and sound of the engine changing completely into a sportsbike/F1 racing car.
