Swift is one level higher than Alto. Swift is level A0 and Alto is level A00. However, Swift is divided into 1.3 and 1.5, and the 1.3 G series engine is used for old models, and the 1.5 M series engine is used for new models, but the engine of the new Alto is an M series engine. I personally recommend buying a motorcycle, if not If you are concerned about space, then the new Otto is enough. If you consider the space of the chassis and power supply, just buy Swift 1.3.
