t'. I've always wondered about the rev counter on the Lexus LFA having to be digital as an analogue needle wouldn't be able to keep up with the engine revs. Really?Ozzie Osmond said:

Ever wondered why rubber ones are fitted almost universally by manufacturers of expensive, high performance cars? The rubber ones are fine.
The braided ones look nice so must be "better". Just like shiny trim in the engine bay. And painted brake calipers.
I would extend that to oil lines as well. Unless wear resistance is a requirement, high pressure rubber lines are just as good, and easier to fit ends to too.Ever wondered why rubber ones are fitted almost universally by manufacturers of expensive, high performance cars? The rubber ones are fine.

Many believe old Land Rovers had aluminium bodies to stop them rusting. Wrong; Steel was very hard to come by post-war, and aluminum was easy to come by. By and large, they've stuck with it ever since.
A shame that everything else around it rots or falls apart

My motorbike has definitely benefitted from braided hoses & I think it's improved one of my cars that they're now fitted to (the previous rubber hoses were 13 years old & had definitely aged).

It will be cost and cost alone. A manufacturer will fit the cheapest component that give the performance they need. Braided will be better, but not enough for the average punter to pay the extra cost.Ever wondered why rubber ones are fitted almost universally by manufacturers of expensive, high performance cars?

You could say the same for brakes, why are expensive brakes any better that the standard ones manufacturers fit.
The standard clutch hose on the elise needs to be replaced with a braided one, or the clutch will not work properly due to give in the line.
Braided hoses are superior, but rubber ones are perfectly adequate. The Braided ones do not expand under pressure, or at least not as much, but it is a small difference, I think the reason most people notice an improvement when fitting them is that they are usually replacing ancient, slightly perished rubber hoses which are expanding more than a new rubber one would, plus at the same time the brakes perhaps get new fluid and a bit of a freshen up.
On the road, the difference is probably marginal and new rubber ones would be fine, think braided hoses are more use on the track where the brakes are being stood on several times per lap, its rare that most people drive that hard on the road. I wonder if vehicle weight comes into it as well, bigger cars need bigger brakes so probably less of a need on an Elise than on something like an M3 ?
If I am going to the faff of chainging brake hoses, I just think I may as well spend the difference and get the best I can, plus they look good.

driving slower is more economical. Yes you might save more fuel, but you will have travelled no-where due to your slow speed! DUHHH
Not sure if being ironic, but,It is partially true, cars are more efficient at lower speeds, there is a trade off between time and distance, the faster you go, the greater the air resistance, the faster the engine turns, you use more and more power, thus fuel to push the car through the air. The same journey at 70, vs flat out at 140 would take half as long but you would use a lot more fuel, at least double, probably three times as much.
The americans mandated the 55 mph speed limit during the oil crisis iirc as that is the most efficient speed for most cars, making some progress, low revs and air resistance low.

Not this old canard again. Different cars are different, butcruising in Germany at anything up to 155 mph costs me about 2-3 mpg,
compared to cruising in speed limited UK at anything up to 90 mph.
Petrol BMW 325, so not exactly a rocketship.
Driving in town costs about 10 - 12 mpg, so speed has very very little to
do with fuel consumption ;->
It's also worth pointing out that the cost of the time saved cruising at
anything up to 155 mph is vastly more than the cost of the extra 2-3 mpg,
even if I costed my time at a relatively lowly £10 / hour.

False again. They just picked a number that was politically expedient.Interesting to note that when the limit went back up to 70 - 80 mph,
road deaths went down.

Nova meaning "won't go" in Spanish so the car was a flop when released in South America. If that were true does anyone not think there would have been at least one Spanish speaker working for GM that would have pointed it out?
At least Mitsubishi realised that rebranding the Pajero in Spanish-speaking markets was a good move before the Shogun went on sale in said countries (and the UK for some reason)... Gassing Station | General Gassing | Top of Page | What's New | My Stuff
