Rio de Janeiro's first combustion-engine bus line began operating in 1908, between Praça Mauá and Passeio Público. On the occasion of the National Exhibition, a route to Praia Vermelha was also offered. Other lines followed, until the arrival of the first electric buses in 1916. Two years later, Light acquired that concession. The company's first experience was with electric buses starting in 1919, when it launched a line that ran along Avenida Central (now Rio Branco), between Palácio Monroe and Praça Mauá. This service was discontinued in 1927, shortly after the introduction of the new buses with internal combustion engines, popularly known as "motores a explosão." The wheels of the electric buses were made of solid rubber, and the traction system was based on energy accumulators, that is, batteries. It ran without noise, vibration, or smoke. In other words, it was everything we still dream of today!

Following the international trend, Light innovated once again by adding to its activities a luxurious urban bus transport service – which offered more comfort and shelter, in a vehicle equipped with suspension that ensured a smoother ride. In June 1926, The Rio de Janeiro Tramway, Light and Power Co. Ltd. created Viação Excelsior. Just as it had done with the trams, it began manufacturing the cabins, importing chassis and engines. The first lines connected Downtown to the South Zone.

This enabled Light to promote the two possibilities that existed at the time – without conflicts and in harmony, for as long as that was possible. Because further along, in the middle of the century, the city's growth and the exponential increase of vehicles on the streets ended up making the streetcars an unviable business.

It was a radically new experience, distinct from that of the horse-drawn stagecoach or the mule-drawn or electric motor-powered streetcar. A new phase in urban transport was beginning with those new cars, all equipped with a speed regulator. The driver was the “chauffeur,” and next to him there was a collection box for tickets, and overcrowding was not allowed. Along the cabins, above the windows, ran a cord that, when pulled, activated the “cigarra,” the sound signal alerting the driver to stop.

In April 1928, the two-story “imperial cars,” soon nicknamed “double beer,” began running between Centro and the Zona Norte on two lines: Estrada de Ferro - Lapa and Clube Naval - Leopoldina. The novelty was a hit. They had three axles, the engines and chassis were imported from England, and the wooden cabins were built in Light's workshops. By 1941, already obsolete, they stopped running.
