No other word.. We use the word bus itself.. Similarly for car, auto rickshaw, cycle, bike or motorcycle, scooter, train, plane, apple, orange, pineapple, etc we use the English words even though there are words in Malayalam for atleast some of them.. Train- theevandi Pineapple- kaithachakka, etc etc..( you can call bus as chathush chakra shakadam but it is not a common word)
The long motor vehicle 'bus' is not an Indian contribution. Very compact and easy name suitable for it is 'bus'. So, you had better call 'bus' as 'bus' in Malayalam too. You can use 'sakadam' for vehicle. If a long word is coined in Malayalam for 'bus', it would be boring.
Generally Malayalees use the English word 'bus' itself to express bus. Infact the term 'vandi' is also used which just means vehicle. For your understanding - many English words have been accepted by Malayalam and is used widely - some common examples are bus, bag, driver, clock, watch etc... Hope this helps.
