We are not talking about the gas turbine as the prime mover any more so I don't want to confuse other posters..
But since you asked, if the turbine is the prime mover for small, quick response vehicle like and F1 car the fuel efficiency wont be pretty. F1 cars present extremely variable loads, and turbines don't like that. The blades will go through rapid heat cycling. Heavy load cycling also. The compression ratio is not speed independent as a piston engine. So you need to spin that up before you can even light it. KERS will take over here putting power to the wheels and spinning up the turbine, but by the time the turbine is up to speed (small turbines may take a few seconds) the driver is off the throttle again (I imagine Monaco), the turbine is signaled to slow down even before it did anything and that's fuel wasted.
You have to keep the turbine constantly near it's best operating range too. The combustor cans work best with a certain range of air flow - go out of that range and proper fuel mixing won't happen, and they will get hot.
There are a number of gas turbine motorcycles you can view on youtube. This one will gulp 32 litres of fuel in 30 minutes, at idle!

Any MGUK assist will surely help, but still doesn't mask that a turbine engine is really designed for a steady load.
