In general, the Type R is faster than the SI. However, there are a few things to consider when making this comparison. First, the Type R generally has more power than the SI. This means that it can accelerate faster and reach higher speeds. Second, the Type R is usually lighter than the SI, which also contributes to its speed advantage. Finally, the Type R typically has better suspension and handling than the SI, making it better able to navigate turns and corners at high speeds.
