In terms of real world top speed (with the speed limiter removed) it is drag limited to around 168 mph. At that speed there is simply too much drag for the engine and gearing to overcome.

In stock form, the car is limited to around 155 mph. This could be a rev limit *IF* that's the type of governor used... where the ECU says "I'm going to cut fuel at X RPM in top gear where X RPM = 155 mph or thereabouts."
