Source of information on this model
Only about 400 original steam cars remain, with around 200 more being partially rebuilt or completely new reconstructions. This specific model is not an original, and was finished in the 2000’s.
This model has 30 hp as far as i know.
Any steam cars added would need unique driving mechanics and sounds. One of the features of Steam cars is having variable power output and also being able to run faster with a lower steam pressure. Though you could maybe skip the process of firing the engine up. As far as i know, most racing-specification could reliably run at up to 80 kmh, though custom reconstructed ones might go faster. There is also the Stanley rocket that could go over 200 kmh.
