Brick-like aerodynamic qualities limit the top speed to just around 160km/h (100mph).
The drag coefficient is around 0.7, mostly because of the flat windscreen and the long wheel arches.
But in 0-100km/h timing it would out-accelerate a Jaguar E-Type.
Rumor is that the Seven was banned from competition in the US in the 1960s for being "too fast to race".
