Lithium Ion batteries again

Euro NCAP tests are nowhere near 65mph even for a single vehicle crash, never mind two vehicles each closing at 65mph. The full frontal is at 50km per hour with side impact at a lower speed.

Euro NCAP - Wikipedia

The NCAP test crashes a single car into a massive concrete block - at 50 kph (31 mph) this is equivalent to a head-on crash between two cars with a closing speed of 62 mph - double the speed of the individual cars.

I doubt that NCAP has ever set test speeds in mph - but British journalists tend to convert to mph.

It took me a few years to get used to switching from km to miles. One of the reasons why I picked up a speeding fine. Same applies to daughter who also got down for speeding.

Many new cars tend to use ltrs per 100km which is much easier to use and understand than mph. Not sure why the UK still persists in using miles instead of kilometres. In hindsight, I probably should have put 65kph.

However my post was not about speed etc but about the weight of new cars. Unfortunately someone chose to focus on my speed error rather than the weight of cars.

I now see where your 65 mph came from. If the NCAP full frontal speed test is 50kph into a solid concrete mass then as Roger says that is equivalent to two cars head on at a closing speed of 100 kmhr. Which is near enough to 65 mph. Query solved.

If we had to go fully metric, I'd prefer km/litre rather than litres/100km - apologies for further thread drift.

You are correct and probably got mixed up again. However most newer cars allow you to choose which option.
