In 1970 Australia’s Ford Falcon GTHO, was said to be the fastest four-door sedan in the world.
Allan Moffat set a lap record in one at Bathurst in 1972.
Now a four-cylinder, front wheel drive Honda type R road car has lapped the circuit in a slightly quicker time.
The phase III HO had more power but to put the power of modern cars in perspective, the two litre Honda has 36% more power than the 1967, 4.7 litre Falcon which was the first V8 to win Bathurst.
Better gearboxes, braking, handling and tyre technology also helps.
