From the specifications shown in Figure 2 below, the apparent reasons for using the SXV550 becomes clear, with a higher power-to-weight ratio, the SXV550 engine would be a preferred choice of engine. In addition, it is about 25kg lighter, and with two cylinders instead of four, as well as an integrated dry sump for lubrication, it would provide a weight saving of over 30kg in all. Yet another factor pointing towards adopting the SXV550 engine, is that the FSAE race car has been operating mostly in the traction-limited region, despite using the largest available tire size as well as the more suitable tire compound, rather than the power-limited region of operation. This means that for most ranges of engine speeds, the FSAE race car is producing more power than it can transmit to the ground, suggesting that there is a tolerance for a reduction in the absolute value of output power.
