We more than likely can build a car with a long range, there is too much going on in the background with countries reliant on fossil fuels holding back progress, or certainly helping to delay things.
We have submarines and supertankers using small nuclear reactors, companies such as Toshiba are creating microreactors, ok still too big for a car but technology is there, if we can fuel a submarine for 25 years I am damn sure someone has a car somewhere that will go plenty more than 70 miles.


Now there is a really terrifying scenario... Millions of cars cutting around with small nuclear reactors on board. Is the general standard of driving good enough?

Battery technology is a stop gap tech and the process of lithium manufacture is far from eco friendly in its own right from what I understand.

As above the future is hydrogen fuel cell.

Hydrogen fuel cells are certainly the future for auto mobiles, I don't think they will ever get a small reactor that small, the smallest one is currently 3 x 9 metres and ideal for a small village, that's an interesting angle.

Read this article and you'll see that all this discussions about diesel versus petrol in terms of pollution are completely ridiculous :


http://www.gizmag.com/shipping-pollution/11526/


The world's 90,000 vessels burn approx 370 million tons of fuel per year emitting 20 million tons of Sulphur Oxides. That equates to 260 times more Sulphur Oxides being emitted by ships than the worlds entire car fleet.

I think that says enough.

France 2013 Freelander 2 SD4 HSE Auto Orkney Grey

Here in France Profonde, diesel cars are de rigueur - just about everyone has one. Diesel fuel is much cheaper than petrol (I paid 1.17 Euros per litre, today), and always has been, here. You were mightily conned in the Former UK!

The French are not easily persuaded to give up their habits, particularly if it's going to cost them, so I can't see any rapid spread of this policy out here - there'd be strikes and riots (and it doesn't take much to encourage the French to participate in either...). Chris

With this, almost certainty, swing back towards petrol, do you think manufactureres will adopt petrol or petrol/electric hybrids?
I am thinking from a torque point of view, small efficient petrol units, with little torque are all well and good in Aunt Doris' city mini but what effect would they have on SUV's or is it an excuse for governments to call the death knell on these too?

A decent hybrid would solve that but the battery issue rears its ugly head, I wonder how far down the road (Scuse pun) the manufactuereres are with battery/electricity harnessing technology. I imagine, rather comically, that the power from the current batteries would be better used to heat water and produce steam Laughing


Petrol engine technology is moving at a vast rate. The end is near for diesel because of the amount of crap that has to be bolted on to a Diesel engine to make it clean, and all this extra equipment saps power and economy.

Take the Vauxhall 1.9 CDTi 150bhp. They are capable of averaging mid to late 50 mpg on the economy front which isn't bad for a 10 year old design. But a friend of mine runs a track car, which is not road legal. He has stripped off every single peice of equipment to do with EGR, DPF leaving just the engine and management system. This has been re-mapped and produces 231bhp and 348lb/ft torque, and on a test on a track day, over four hours averaged 89.6 mpg at an average of 55mph. So the economy and power is there, but the emmisions and smoke went through the roof! 127% over the limits allowed for an MOt test. So diesel is getting to its limits regarding Euro emmisions standards. If they start taxing cars based on NOX limits, then Diesel engines will be dropped over night.

Back to petrol, and the question about enough torque etc, I have friends who are very high up in Vauxhall, and they currently have in development (which is production ready) a 1.4 Turbo which produces 200bhp and over 200lb/ft torque.

This is massive for a small engine. They also have 2.0 Turbo's which produce over 280bhp with less that 160g/km emmisions similar to that used in the latest Astra VXR 280.

Within the next 3-5 years, all petrol engines will be turbocharged which answers the question about torque.

Mav do you know when Land Rover plan to start putting the ingenium 2.0 Turbo petrols in the new Discovery Sport? As someone who mostly drives on country lanes, modern diesels are not really suitable. I am now a self diagnosed land rover addict. The Evoque is a little too flash for my taste so the early FL2 without DPF is the only option for me at the moment. I live in hope the world will see sense and drop the current diesel addiction! A modern turbo petrol engine may not have the torque band of the TD4/SD4 engines but is far superior in every other respect.


The DS that was in our local Shopping Mall in Leicester was an Ingenium 2.0 Turbo petrol. But I know from within LR that no decision has been made yet as to whether the petrol DS will be launched in the UK.

But I suspect that there are a few within LR are debating whether launching DS with the old engine is a good idea Whistle Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather. Alpine DVD - Privacy -Evoque 20" Dynamic Wheels and more to come.........

Why turbo over supercharger? The current motorbike I have is Hondas go at an economic bike, which is a low revving 700cc which does 80mpg, its rumoured Honda are going to release a supercharger version of it.

As a Supercharger is driven from the crank, it adds load on the engine which in turn will increase emmisions produced by the engine. This is why the majority of cars now have electric power steering to remove the hydraulic pump from the engine.

Turbocharging doesn't need any mechanical power from the engine to drive it. It's free power from waste exhaust gases to spin the turbo.

Supercharging does make sense on a bike as there is less weight to push so supercharging maybe more efficient on this application, supercharging also doesn't produce the heat that turbocharging does. Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather.

turbochargers use wasted heat energy to produce power so create less parasitic losses than supercharger that are belt or gear drives to spin the compressors/rotors

Sorry but First law of thermodynamics rules ie you can't get something for nothing. Bit like saying that your alternator is turning so your lights are on for free.
