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.

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 :

I use to love my old petrol land rover V8 but unfortunately it loved the petrol stations and I've never had a petrol engine since. MY13 HSE LUX Aintree Green

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!

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.
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 Freelander 2 HSE Lux 2013MY - Barolo Black with Ivory Leather.

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.

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

Ok, makes sense, thanks.

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. |

We all been here before, diesel bad all jump ship and get petrol car's again and then wonder why petrol is so much more expensive than diesel you know the script. MY13 HSE LUX Aintree Green
