OT: Brakes seizing on electric cars?

More likely to shave a quid off the cost

I presume earlier cars had a four-speed box plus a two-speed overdrive box "in series" because it was easier to do this than to design a gearbox that had 5 or 6 ratios.

What changed, around the time of the first British cars with 5-speed gearboxes, that allowed 5-speed to become possible and later standard? I believe the Austin Maxi was one of the first to have 5-speed.

FWD and an integrated gearbox and differential, with constant velocity universal joints.

Rubbish.

What changed was the M1 and the need for cars that could run all day at

70mph+ without blowing up.

Like German cars could.

A front wheel drive engine/gearbox layout generally had a directly driven layshaft, whereas conventional RWD layouts had an intermediary gear to drive the layshaft. It's easier to add gears on the former and maintain efficiency.

On some RWD cars the 5th gear was an extension to the 4 gear variety, with an casing extension. It also made dismantling more tricky.

Interesting that my 1923 book has the two shaft input and output as the primary diagram, and the top-gear-straight-through as a secondary variant.

But then I've never owned a car with a propshaft. I know nothing.

He didn't attribute it to you. It's quite clear from the level of indents what lines "Commander Kinsey wrote" refers to. Get a decent newsreader which colour codes them as you read and it's much easier to look at.

Then instead of failing slowly it would fail unexpectedly and quite suddenly, despite the so-called SMART data saying 99% life left.

It is impossible for any sensible person to draw that conclusion from what I wrote. I just asked for clear distinctions in colour.

And they still can't use the last 5mph of energy?

The legendary Sinclair C5 had regenerative braking.

Then they should. Or some equivalent alternate coils they can use.

It would add weight and complexity, and there's **** all energy left by the time you've gone down to 5MPH. Don't forget kinetic energy is proportional to V squared.

So it should be easy to remove this small amount of energy. Change the coils from series to parallel or something.
