Using adequate clothing layers I have no trouble keeping a high core temperature outdoors in any conditions, but that makes no difference if one has Reynauds syndrome as I do. Then as soon as a hand for example senses a triggering temperature, the blood supply to the fingers instantly cuts off...

I agree the possible advantages of multiple motors but think a single motor is best in the market, since it does the job anyway with simplicity at much lower cost. Unsprung weight should always be as low as possible as a ratio of sprung weight, since that enables the wheels to most closely...

You are considering too many irrelevant issues and not considering the most important one, what the customer wants. They don't give a stuff about efficiency or saving the planet or an other such technicalities. They like their often big hybrids with loads of boot space and the protection they...

And a single third party insurance cover element if both cars had one nominated driver. At present such drivers are being ripped off by paying double third party cover. Another simple solution to a very occasional need for a long distance run is car hire of course, cheaper than having a second...

That's a very odd view which completely ignores the hybrid advantages for utility cars. I can only imagine you are thinking of direct hybrid, ignoring the precharged aspect and electric only use of todays hybrids and how so many people use their cars. See this post to understand what I mean. .

Old style hybrids like the earlier Toyota Prius are a waste of time, I agree, but today's precharge hybrids most certainly are not You seem to be ignoring the huge swathe of the car driving population who only do under 5000 miles a year, many very much less. Most of their mileage is very short...

With the exception of the wheel motors, the best current hybrids from GM are already like this, always electric drive including electric only operation for the first up to 80 miles. Then hybrid operation by charging the battery at fixed revs high efficiency ICE, so the battery is a buffer. I...

i believe the American one was only ever a prototype. The Rover was extensively developed but the Achilles heel of jet turbines for road usage was their fuel greed. Even in the most ideal conditions they couldn't get remotely close to piston engined ICE economy even back then. Wankel is also...

No, it wasn't gas turbine or ramjet as also guessed at. Both of those had already been shown to be dead ends. Its closed in appearance ruled out all that kind of possibilities. In the event it was obviously a nonsense claim with not even input-output checks permitted. Another one like the...

You cannot know that before seeing the program, and maybe not even after! Your "But is it" and "Maybe" are just the biased pessimistic pre-judgement of a "leaver" in an attempt to discredit. .

You're too much of a pessimist. The conditions won't materially change in the next 8 years for the London commuting driver, and that's what I posted about, puting the worst light on it. In reality the savings will be greater. There's no point in quoting about it not applying to others in...

Next Monday at 8pm on Channel 4, a Dispatches program will be revealing the increasing cost of food etc inflation due to Brexit. Titled: Brexit and your sinking shop It will also be available later on 4OD online. .

The Stirling atmospheric engine is a no hoper, totally inadequate power to weight ratio and very inefficient. I completely agree with you on long distances, pure ICE wins hands down. But the vast majority of all car journeys and most of drivers mileages are short distance journeys well within...

True in most parts, but not for a London commuting driver. Daily congestion charge is £11.50 which for a typical 230 work days a year person is £2645 per annum. If they buy a middle of the range Nissan Leaf with the longer range 8 year warranty battery it will cost about £25,000 with a small...

Useful on solo bikes for a very wide range too, and as low as 4mph to 20 mph for a load carrying bicycle. .

I remember that too but was sure at the time that it was a flight of fancy. Those responsible for it subsequently refused to allow it's inputs and outputs to be measured, which would have proven its worth without revealing any secrets. For two reasons I don't believe in conspiracy theories of...

Typical Chris Evans narrow minded idiocy, quoting worst case and also omitting the fact there's the range extender version with auxilliary charging engine. Fact: The vast majority of all car journeys are far below the minimum range of the i3. Fact: A high proportion of car owners never travel...

The designs are all much higher revving than yesteryear. You mention Ford, but they've dropped the slower revving series like the old 1.3 in favour of the high revving Zetec designs. Personally i think that's a pity, but it's the way the market leaders in engine design have gone. Actually...

And of course the rotary crankcase valves of some two strokes and the twin piston two strokes of the sort promoted by EMC-Puch. There's been many ways of induction without valve springs. .

Sorry to depress you, but last year there was a waiting list and a lucky persion allocated one could sell it at over list! Being a BMW driver can also take the form of one-upmanship since it can be about self-perception of a superiority, sort of "Look at me, aren't I amazing". Clarkson was...
