There is more to the S Line Premium than just a stronger engine. It also gets a sport suspension to better handle that power, and unique exterior elements like different wheels and illuminated aluminum tread plates. The 0 to 60 mph sprint time drops to a more impressive 5.4 seconds, and gas mileage barely takes a hit for the extra power. If you can afford it, there really is no downside to upgrading the engine.
