Triumph cars with highest top speed

Top speed is, probably, the first performance metric that comes to mind when comparing fast cars.

Top speed depends on balance between engine power and aerodynamic drag - the more power and less drag, the higher the top speed.

High speed stability also matters, since too low downforce can lead to loss of control at speed.

In recent years high performance cars have been tailored for track performance, which, unavoidably, reduces top speed. Therefore the overall top speed is used less in supercar comparisons.

Despite this shift to increased downforce, modern supercars are faster than their predecessors - all thanks to dramatic increase in engine power over the past few decades.
