Porsche 918 Spyder can do 0 to 97 km/hr in 2.1 seconds.
97km/hr = 26.944m/s
26.944 in 2.1 seconds gives an acceleration of 12.83 m/s/s
The factor of g is 12.83 / 9.8 which equals 1.31.

Using a 1:1 of ratio of g to Gee, the Spyder can give an excitement of 1.31 Gees*.
A top fuel straight
line dragster gets 5.3 Gees**. 5.6 Gee is the record for this vehicle***.

*using a little calculus, the actual gravitational g could be included in the motion.
**5.4 Gee with a stationary approximation of gravitational g included in motion.
*** wikipedia of course.

Batteries and electric motors are only going to get better but hopefully breaking Gees (Whoas) will always surpass the Gees.

Looks like Russell Boardman experienced the
aforementioned breaking Gees when he stalled his Gee Bee
and encountered the ultimate breaking brake. The ground.

It was a one-off race plane, fast, tricky and utterly unforgiving, little more than a huge engine with guidance fins on the back ... it didn't even need wings, if you look at the math (power vs. MTOW, 1,394.8 kg vs a 596.5 kW powerplant) it could accelerate vertically from rest on engine power alone, like the later Pogo.

As if 2020 wasn't bad enough, I've had the Bee Gees
"Too Much Heaven" going through my head for the
past 4 days. I would be willing to listen to Nickelback
at this point to get it out.
