Continued use of diesel has been looking dodgy for a couple of years.
We need better for sure.
The French are (were ?) very big on diesel so if this is real diesel has a problem

I much prefer the torque characteristics of a diesel, and being as my Volvo is pre cat and pre particulate filter I still get good economy without all the problems.
Perhaps we can go back to long stroke side valve petrol engines ?

I see diesel going first, maybe bot for a few years, then petrol, not for a looong time.
Two stroke being phased out on motorbikes

Seems Renault can't afford to make future Diesel engines meet forthcoming emission regulations.
I'm sure if they asked nicely Bosch could rig them up a little something |

No more new ones can be ordered because they can't meet stringent new emission regulations. But there is nothing to stop rail firms updating and replacing engines in older designs that probably have not met emission regulations for many years and do NOT have to meet current regulations. |

Deltic, anyone? A trifle too many emissions, but what an engine!

Batteries give even more torque. You should try a Tesla. I would have bought one of them if I had a driveway or garage for charging purposes. |

So, if I converted my Renault van to electric, with four traction motors, and a Deltic engine and generator in the back it should go like stink ?
A bit like the Top Gear DIY version but scaled up.

Even the relatively small battery in my Honda CR-Z hybrid makes the 1.5l engine feel more like a 2.0l on acceleration.
I agree, the Tesla cars are fab.

They've got one of those hundred grand Teslas in a shop near me. Great car. There's cheaper models to come as well - think £18000 and £32000 are the prices but that's 3-5 years away, The hundred grand model is 0-60 in 2.5 seconds!
£12,000 deposit then £500pm - bit pricey but low running costs. £4 to fully charge it.
THATS the way forward.

The way forward?
I think it rather depends on where the electricity comes from. If we all started to use electric vehicles tomorrow, there would be a rather tricky energy crisis.
An electric car is only clean if measured at the road - the energy still has to be generated somehow and at the moment, any electric car in the UK is 22% coal powered and 34% by gas. 21% nuclear. I don't fall for the lie that nuclear is clean energy - just because it has low CO2 emissions doesn't make it 'clean'.

Not sure about all the ins and outs but I do think these electric things ARE the way forward. The wee electric scooters just now are great! No energy production is "clean" - we simply have to accept that. Personally I'm for nuclear - it's really the only efficient way.

The UK government sabotaged solar for no obvious reasons. But a set of solar panels on the roof should be able to charge up your Tesla.

The hundred grand model is 0-60 in 2.5 seconds! I was following an original Tesla Roadster (lovely car), or at least I was successfully until he decided to put his foot down. Impossible to keep up with it! |

The production of batteries for Teslas isn't so green and what happens when the batteries need replacing? I've heard some say the car is just about a write off at that point, I've no idea whether there's much in the write off thing but I'm sure the batteries won't be cheap. I've been in one of the Amsterdam Tesla taxis, they certainly are very rapid and quiet.

The Prius is the 'test case' for these and there have been few battery failures. Toyota have been replacing them anyway.
Battery tech is still very young; the energy density needs to be improved and eco-construction depends on the chemical design, which is also maturing. The new Tesla factory looks magnificent and I think they will lead the way.
Ultimately, as Chris pointed out, it's no good charging a car battery when the electricity is still produced by coal firing. The entire infrastructure needs to be upgraded.
