The N600 was developed alongside the N360 in order to target export markets like the US and Europe, where motorways demanded higher top speeds.
Just seven months after road testing the N360, Britain’s Motor magazine tested a Honda N600 in November 1968. They reported that it had a top speed of 77.1 mph (124.1 km/h) and could accelerate from 0-60 mph (97 km/h) in 19 seconds.
An overall fuel consumption of 36.3 miles per imperial gallon (7.78 L/100 km; 30.2 mpg-US) was achieved. The test car was priced in the UK at £589 including taxes, at a time when the Mini 850 was retailing for £561. The testers were impressed to find 1100 performance from a 600 cc car, but found it ‘very noisy when extended’. They found the Honda as easy to drive and park, and ‘quite well equipped’.
The performance figures put the car at or near the top of its class under most criteria, reflecting its favourable power to weight ratio. The car was thus 5 mph (8.0 km/h) faster than the 72 mph (116 km/h) achieved by rival magazine Autocar in an N360 in May 1968, and more than ten seconds quicker to 60 mph (97 km/h) which the N360 achieved in 29.3 seconds. Consistent with its slower performance, the N360 squeezed 3 extra miles out of a (UK) gallon of fuel, managing an overall 39.4 miles per imperial gallon.
