OT: mpg question

With a BEV, you have a battery cooling system, power steering, and other accessory loads. There is probably some sort of tradeoff that makes a moderate speed the best choice for them too. Just sitting in a BEV, and being comfortable, has a cost.

"Watt hours per mile versus speed" (a graph to show curve shape)

BEVs still have creature comforts. That's to stop the early adopters from whining too much.

You have those loads with an ICE, with the (notable) exception of heating. I'm not so sure of the battery/engine cooling needs - similar overall?

Why don't they have blinds?!

Indeed. It'll be interesting to see what *really* motivates BEV owners once their use becomes more widespread.

And I think that even when the 2-stroke was replaced by a Vee 4 from Ford, they kept the freewheel device.

The 99 had the slant 4 from Triumph (same engine as the Dolomite). And yes it had the freewheel, at least initially, but I think they deleted that after a few months, not sure why.

I too thought the 99 had a V4, but looking at Wikipedia, I'm thinking of the

Probably people wanted engine braking since with a 4-stroke it was now possible. Saves on brake discs/pads ;-)

Saves lives when your brakes are single circuit

My mates J-Reg (1971) 96 V4 had the freewheel.

Much cheaper to make them dual circuit.

Oh dear. Lackseny brain

How can taking a freewheel OFF a car be more expensive than ADDING dual circuit brakes?

Even for you Rodders, that is pushing the canoe further up s*it canal without a paddle

We'll see...

What matters is the cost of each approach in future cars made, stupid.

When did dual-circuit brakes become mandatory on cars? I presume it happened earlier on 2-stroke cars because there was no engine braking as a fall-back, but even on 4-stroke I'd have through it was many decades ago - I'd have guessed long before the last 2-stroke car.

How smoothly did the freewheel engage again when you applied power - did you have to be careful to apply power gently to avoid it snatching? I presume it used a cone-clutch rather than a simple bicycle-type ratchet.

Were there ever any cars which used a compressor to feed the fuel/air mixture, as opposed to crankcase-scavenged which required a) petrol/oil mixture, and b) freewheel to avoid the engine being driven quickly on overrun when there was no oil because of no fuel/air/oil mixture. I presume crankcase scavenging uses a bit of engine power - evidently it was less than a crankshaft-powered compressor, or maybe crankcase-scavenging was done to keep things simpler.

I'm amazed that 2-stroke petrol engines are still legal to use, in these days of wanting to reduce pollution. Or are burnt-oil fumes regarded as less of a problem than conventional fuel-exhaust fumes?

Once you realise that emissions legislations are and always were a way to increase car sales and induce obsolescence, and had nothing whatever to do with dangerous climate change, the reason why a tiny market of mainly agricultural 2 stroke engines has been left alone, is obvious.

No money in it and no obvious alternative.,

It hasn't in many jurisdictions.

you're beyond stupid.

Wota stunning line in rational argument you have there, child.
