Definitely! I've once done a trip of 800 km in an Alto and the only problem we faced was that the engine kept getting heated very fast. We got it checked from a mechanic as well but he did not find anything amiss. Perhaps the weather being hot had a role to play.
Also several factors affect your decision of going on a road trip in an Alto, for example, the number of people, the amount of luggage, the terrain, the weather, etc.
