60 bhp per litre. The same as a '64 Mini Cooper S. Just what you'd expect

Well racing car engines possibly. Not many road tuned cars will do it.

100bhp / litre was the mark of a "tuned" car 25 years ago and it often
meant something that had a lumpy idle and didn't deliver until 3000 rpm.
These day's it's just hot hatch territory and 120bhp / litre is nothing
unusual for a perfectly well behaved road car.
