The original 1948 model that produced only 9 hp had a 0-40 time of 42.4 seconds and a top speed of just 64 km/h.
The top speed increased with engine size to 80 km/h (49 mph) in 1955, 84 km/h (52 mph) in 1962, 100 km/h (63 mph) in 1970, but was finally not capable of US freeway speeds of 115 km/h (71 mph) until 1981
Looking at the speed a vehicle can achieve is not enough. You also need the consider how rapidly the vehicle can dramatically increase its speed. Some bikes and cars can go from a sedate pace to a pace beyond the capabilities of the driver so quickly that the driver doesn't have time to adjust to the changed circumstances.
