There are gas turbine based buses and trucks used in eastern Europe where LNG imported from Siberia is plentiful.
They're not common in my city, but there's (only) one on the bus line that drives by my house. It's only a bit louder than piston engines buses, but the sound is very distinctive so you can hear it from a mile away.
