General Car Chat / Re: If JLR go under...

Thieves don't nick them using keyless entry on the more recent cars, and any car from any manufacturer is prone to relay attack when on the older tech (Fords being the most nicked car). When you look at different countries you get differences, Merc and BMW in Spain, Kia Stinger in Germany.

The challenge is that the JLR products are one of the most desirable and hence they are targeted by the big crime teams, they found a way to hack and decode the CAN interface (they could do this for any make but, most are not worth bothering with as its expensive to do). That said, many of the cars that get nicked are not locked (we have all the stats and meet regularly with the Police car crime team)

This can hack method is being closed (and does not work on the latest models).

Its an arms race, and always will be, we have further tech in the wings for the next gen.

For whatever reason using the heater while going along uses a lot more energy. I suspect it's down to 2 factors. Firstly you have 60+ mph cold air going over the surface of the car, sucking heat away and second the car can defrost itself in 5mins tops (both mine had heated front screens and strong heaters. Meaning they weren't running heat for very long.

Also both mine had heat pumps rather than just blower motors and heaters. I think this makes a substantial difference.

Depends on the car, with a heat pump it should be using no electric heating at all when on the move and should be recovering heat from the motors, inverter and battery  :y

Quite rare  8)  not a clitoris car by any means

I doubt he would be able to tolerate the downgrade in comfort, features and handling

Back to modern cars with modern, useless, pointless shit to appease the misinformed idiots....

I'd love to meet Sir Ian Callum in a dark alley.  He was the fikkin' moron who was chief designer of my car, so he was the one who signed off in putting that engine in it.  Braindead waste of carbon.

Er no, he signed off nothing more than the exterior shape of it, the design team have no interest or influence on what is under the skin and get mightily pissed off when you impact the outer skin (they currently hate shark fins and want a Merc S class 'ditch' approach which results in shlte connectivity).

Blame power train

The drill ships were 3 phase 6.6kV 60Hz at around 12MVA (which was a pain as they ran an 11kV main 60Hz bus).

The QE carriers are 11kV at 60Hz (they, surprisingly, used rotary frequency converters) at a big power level, probably around 20MVA

Sleipner had no shore supply as it didn't really have a home port, it would have been 11kV 60Hz at probably around 12MVA to hit the base load.

The platform support vessels never had one as they rarely sat around for any time being the transits of the sea.

There is actually a standard for prison cruise ships, it was 6kV or 11kV (most shore supplies were dual voltage) at up to 20MVA

We always used to recon on a shore supply being about 3 times the emergency gen capability.

According to my "local" BBC Southampton News, the port has plenty of electric hook-ups for ships to power them in port, but none of them do, as its cheaper to run their onboard generators instead.

There is no 'standard' for shore supplies (what a surprise!) due to different voltages and frequencies of the ships and local setup.

Consequently most can only couple up in their home ports, and unless they are there for a a longer period its not worth the faff and hassles of a shore supply (its not some stonking great big plug, it is physical wiring bolted to a bus bar and big switch). The only ones I have seen use them in anger is naval vessels and some drill ships as they have home ports.

Modern car wiring has been hit by the greenies.

The adhesive in the cloth tape is now 'organic' so attracts the little buggers (and bigger ones) so the loom manufacturers have had to put chemical nasties in the glue to detract them......so probably not nearly as 'organic' as it was

As the sun started to come up this morning, I put the space saver on the back of hers, and dropped the wheel I took off to my grumpy MOT man to remove the screw...

That was a nice birthday present for her  ;D

Emissions for ships does not apply in international waters for most of the planet, so they tend to be clean(ish) in territorial waters, then switch over to any old cheap crap when outside.

When I was at GE delivering vessel control and propulsion systems, it was quite an eye opener as to the lengths the vessel designers went to to make this all happen, extra tanks, extra pumps, fuel heaters, different engine/governor/avr mappings etc etc.

They have at least introduced ballast water cleaning systems to try to stop the carrying of invasive species around the planet (some of which were even massive power consuming microwave setups)

I found it amusing when one of the Greek officials said that the British Museum only want to keep them for ticket money..........it's free entry!

Most of our cars end up as complete runners in far off lands of questionable ethics (Africa and the 'Stans being the usuals), we have also seen Ukraine cars arriving in central Russia in recent years.

This change closes a back door which allows a key to be programmed once in the car

Blimey, the press do get it very wrong don't they!

Its nothing to do with relay attacks!  ;D

On the rare occasions I do stick religiously to the limit, there's always an angry queue behind. People are used to driving 5-8mph over the limit, and it really pisses them off when others don't.

Go to Wales, stick to the 20mph limit and see how you get on!  ;D

Having been recently, you struggle to see 20 in a 20 and seem to constantly be close to 20 even in a 30 or higher  ???

Not convinced they are stainless, the coating looks to be zinc, they also state Surface Treatment: Primary Color + Zinc Plated White Blue Color and why would you zinc coat stainless ???
