What sort of G-Force , if any , could you experience accelerating from 0 to 186 mph in 9 seconds ?.

Round about 2G. You experience 1G normally, and the acceleration of this vehicle, "significantly under 9 seconds from 0 to 300 km/h" works out as between 9.24 m/s/s and 10.3 m/s/s, assuming the slowest time to reach 300 km/h is 9 seconds and the fastest is 8 seconds. 1G is the force caused by the acceleration due to gravity, which is approximately 9.81 m/s/s, so the acceleration of this vehicle adds another 9 - 10 m/s/s of acceleration to the body (your mass remains constant). This means that the force on you doubles, approximately.

Yes - if the car was going straight up at 9.81 m/s/s
In this case you would get a vector resultant? Gravity acting down and car acceleration acting along the line of motion - 90 deg to gravity on a flat road.
Therefore resultant is approx. 13.87 m/s/s at 45 deg towards the ground and rear of the car? 1.414 x G

Quite happy to be proven wrong - long time since I did that sort of maths!!

Another thought, being used to 'normal' gravity would the brain only sense the addition acceleration component?

So what you saying is Kin quick:)
