A. Install VID to guest’s car which is brought by guest only and then, Let guest drive his or her own car

B. Before Installing VID, measure the emission gas of guest’s Car which was randomly selected and then, measure again the emission gas after installing VID.

C. Do the racing test between cars with and without VID Car for checking the acceleration improvement.

D. Let guest’s car climb the hill or slope for checking the climbing power improvement as well as checking the driving time by reaching the given test distance between cars with and without VID

E. On the flat ground, start the guest’s car and drive the given test distance to measure the driving time for the same guest’s car before and after installing VID

F. Before installing VID, starting engine to check the engine noise and then install VID. After installing VID, start engine again to check the engine noise to compare engine noise level.

G. Set the given test distance and driving course. Set the given test transmission gear level. Set the given test fuel volume to the standard test bottle. Drive the car at the same speed and check the fuel consumption before and after installing VID.

• Important is to keep same driving course, same transmission gear level, same speed and only use 80%~90% of fuel at the standard test bottle for precise comparison.
  → The existing fuel at the fuel intake lines practically generate the big difference of driving distance

※ Mandatory Condition for Comparison Test

(1) For fuel consumption comparison, constant load should be given to test car - driver’ weight, vehicle’s another load etc.

(2) Same fuel should be used for testing ? fuel’s composition should be same.

(3) How to inject fuel to fuel tank of car itself is also causing big difference. So, use the additional test-purpose standard fuel bottle.

(4) Make sure the same status of wind direction, road condition and driving course - including the same condition like the traffic signal to decide stand-by time or driving time and distance.
