Well, the Rimac might meet its match with the Venom F5. Its performance claims might even eclipse those of the Rimac if we can get them tested and verified:
For the dry 1,360 kilogram Venom F5, Hennessey is aiming for a Vmax target of 311 mph (converted 500 km / h). The name is also derived from this speed: F5 stands for the highest tornado category, which can reach wind speeds of up to 512 km / h. The highest gear is so long that theoretically even 534 km / h would be possible. For comparison: the predecessor Venom GT, weighing 1,244 kilos, had reached a top speed of 435.31 km / h on the Kennedy Space Center site. The acceleration values of the Venom F5: zero to 100 km / h in 2.6 seconds, zero to 200 km / h in 4.7 seconds, zero to 300 km / h in 8.4 and zero to 400 km / h in 15, 5 seconds.
