Diesel vs Petrol vs Electric

PETROL vs DIESEL (vs ELECTRIC CAR!) – which is REALLY cheaper? | What Car?

I forgot to add a V8!

 

I wouldn't touch the latest petrol and diesel engines with a barge pole! All the increased efficiency takes its toll in longevity unfortunately.

Electrics surprisingly expensive, but UK prices seem to be quite high.  29p/kwh = 0,34€  

With a good deal here in Finland you can get around 0,15-0,20€ / kwh.  Before Putin started waring it was around 0,1€ / kwh

I'm amazed by the efficiency of that petrol. I drive a Mirage and get 40mpg/us which I believe would be 48mpg/uk gallon and it's a much smaller car than the Peugeot. Next car will probably be electric, torn between the Fisker Ocean and the Lucid Air, electricity in Texas has gone up as well but still only 0.11Euro/kwh ($0.12). I used to have a 2001 VW diesel and no matter how you drove that it would always average 58mpg uk gallon (48us)

Got a 2013 VW and it's around 48mpg. A full tank averages around 600miles / 1000km. 

Still no buying an electric for a long time. I don't have the money for a brand new one and if I get used I'd be dreading that I need a battery change at some point. If it comes to that, you're spending a lot more than you would with an ICE.

Same deal with hybrids, was looking at the battery prices and it's around 10k for those small batteries that have a range of 20 miles or so. Just think home much gas you could buy with that.

Renault (not that I would consider buying one) offer battery rental on at least some of their cars. IT should actually be mandatory for manufacturers to offer this. 

I would never get a hybrid, as the engine will always start to required revs for driving when it is cold, which will reduce its life considerably!

Not sure what kind of hybrid you are talking about. Self-charging?  My only experience is with a Kia Niro which is a plug-in. Something like 60km range.

Engine idles when it's cold or there no juice in the battery. If you floor it, it will use the engine.

Works fine in -30C but it does struggle to heat the cabin, fortunetly we don't get many that cold days.

I cannot believe that in a plugin hybrid the engine is always idling when you use electric power, that would be ridiculous.

It does that when it's cold. You have to get the heat the cabin somehow.  

At first I was thinking it is kinda ridiculous, if you need to run the engine for heat, might as well use it for driving too, but idling vs driving takes way more fuel, so it prioritizes using electric always.

I think it's pretty good solution overall. Most of the time 60km will be enough for the days driving needs, so your driving 90% with electric.  No range anxiety if you suddenly need to take a longer trip. In a more moderate climate it would be even better since you don't need that much heating.

Didn't think of the heating. Unfortunately the petrol engine runs dirtiest and inefficient when idling cold. 

I would consider a hybrid with full electric drive and the engine as a "range extender", Mazda is developing a wankel engine for this application. That is way more efficient.

Yeah, I think that would be the best of both worlds. If the engine is small / light, and really efficient as a generator.
