0 to 100 Km/h acceleration for Vitz 1.5 is about 9 Seconds, which is almost good to beat any local stock car, although I am not sure about top speed on Honda Vti and Altis.
In terms of performance even the 1.3 Litre engine powered Vitz can rule many larger cars.
0-100 Km/h time for 1.0 Litre Engine Vitz is about 13.6-14.1 seconds, which is a fairly decent number for a car of its class.
