And before Dull comments on gas price being too high, spare a thought for those outside the U.S. US gas prices hit fresh high of nearly $5 a gallon as UK sees record equivalent to $8.60 |

Since yesterdays increase to 183.16 per liter (petrol) comes to £95.24 (based on the info that follows). Since I am now officially retired, have 3 options. 1: OAP bus pass & Senior Citizen's railcard (job done if no personal transport required) 2: Purchase a car either petrol or diesel. 3: Purchase an EV. So got the time on my hand to do some research (needed because of 45 years in the transport industry, have many questions/concerns regarding EV's). Fuel efficiency/Distance/Cost. Could only find comparable info up to 2019 (so far). Top 10 cars for efficiency So based on the No 1, a full tank will cost £95.24 at today's prices (possibly more), giving a total travel on 1 tank of fuel of 1,112.69 miles. While travelling that distance, any heating & other electrics will be provided by the battery/alternator, so not bad. Now for EV's. How long does it cost to charge an electric car UK?So for the same distance traveled as the example above, the cost will be £83.45. Not bad, a saving of £11.79, BUT... An EV in cold weather will take longer to charge. An EV in cold weather will seriously impact range due to all the electrics being used. Current cost of Electricity. Time. A 200 mile trip in a car will take approx 3.75/4 hours (includes a pit stop to refuel it's passengers). I suppose 1 can charge up their EV wile on a pitstop (if they don't have to queue at the charging points). That saving doesn't look so healthy now does it? Also, bear in mind that commercial rates are higher than domestic rates. |

As always, take your pick of the numbers... For a good selection of EVs, we have (ev-database.org - Energy consumption of full electric vehicles) a range of 0.1kWh/km to 0.3kWh/km... For example, a heavyweight Tesla Model 3 comes in at 0.15kWh/km. So... Comparing that to a typical 50mpg fossils powered vehicle, we have 50 * 1.6 (km) / 4.5 (l) = 17.8 km/l = 0.056 l/km. Hence for 100km at current UK prices we have: For an EV: 100 * 0.15 * 28p = £4.20 For fossils: 100 * 0.056 * 200p = £11.20
Middle EV: 100 * 0.20 * 28p = £5.60

Have I gone wrong with those numbers?YES, & glaringly as well. Switch back between my post & yours & you should see why. |

Ok... So if you want all that for 200 miles, then just multiply up by 2 * 1.6 = 3.2 to give: Hence for For an EV: 100 * 0.15 * 28p * 3.2 = For fossils: 100 * 0.056 * 200p * 3.2 =
Middle EV: 100 * 0.20 * 28p * 3.2 =

NO :-) 1: you compared Apples to Oranges. 1 km DOES not equal 1 mile. The example used a Ford Focus with a fuel efficiency of 52 liters for 1,112.69 miles (1,790.70098 km). You used an example of practically half that. Oops. 2: My post was research for MY options but offered it for comparison for others doing research. 3: An overnight full charge, even though nice, will not get me to see family members spread throughout this country on just the 1 charge. For example: Newcastle Nottingham Derby Welwyn Garden London Canvey Island Bournemouth 3 of those will not do the trip on 1 full charge. Then there is the Autumn/Winter months when from all indications seen to date seriously impact range NO matter how much battery technology has improved. Then there is the higher capacity batteries that will only charge 80% of the battery due to the heat element. Oops. Then there is the difference between domestic rate & commercial rate which would be required to complete those trips. Then there is the added question of home charging points. If none at any of the home destinations, commercial rates again come into play thereby throwing yours number in the bin. :-) Don;t get me wrong, not against EV's. Have not only ridden in one but also driven one - nice. Until they greatly improve the range & number of charging points throughout the country, they are just a niche market for the rich atm. |

Then there is the higher capacity batteries that will only charge 80% of the battery due to the heat element. Oops. It's not that the batteries only charge to 80%. It is that at 80% fast charging stops, because of the heat problem, in a correctly designed charger. The charging cycle is constant current up to 80%, battery voltage about 4V/cell, and constant Voltage after that, which is a lot like lead-acid batteries where the charging current reduces to virtually zero when near full charge. It's quite probably that the commercial charging points don't do the last 20% because it takes so long, and only charging to 80% means more money can be extracted from more customers. |

... 1 km DOES not equal 1 mile. The example used a Ford Focus with a fuel efficiency of 52 liters for 1,112.69 miles (1,790.70098 km)... Hence the 2 * 1.6 = 3.2 conversion factor for 100km -> 200miles. (1km = 1.6miles) OK, so for Ford Focus, taking the first example from "Ford Focus fuel consumption, miles per gallon or litres/ km" gives Ford Focus 1.4 l: "Car fuel with highway drive: 5.4 litres/100 km (43,34 miles per gallon)" = 0.054 l/km. I've assumed 0.056 l/km so for that example, the fossils calculation now reads: For fossils: 100 *

What grand tour? I stated the following: Officially retired. Family spread throughout the country. DO you visit your family members all in one hit? As for mileage. That 1,112.69 miles was for a full of tank of fuel which for the Ford Focus is 52 liters,, 11.5555 Imperial gallons. That equates to 96.291 mpg. A 52 liter tank & one tankful of fuel - NICE. Yeah, I know hard to believe. However, the numbers don't lie (unless Car News were doing a late April Fools joke), If that efficient, then EV's have a fair way to go. @Wiggo. Thanks much better price range & no electric costs domestic or commercial. Traveled back & forth to Cambridge in a Toyota for a few years, nice car so will look into that further. :-) |

... That equates to 96.291 mpg... Sorry, but I can't believe that is a realistic figure... ... Unless that is for a Focus motorbike or some sort of re-imagined Robin Reliant? Or is that for zero load at 25mph?... Keep searchin'! Martin See new freedom: Mageia Linux Take a look for yourself: Linux Format The Future is what We all make IT (GPLv3) |

Don't know of any motorbike capable of having an 11.55 gallon tank. :-) Yeah, I find that hard to believe as well, but... 10 most popular cars by maximum distance travelled on one tankful. # Model Distance (miles) Tank Size (L) Cost to Fill 1 Ford Focus 1,112.69 52 £66.75 2 VW Golf 1,046.12 55 £70.40 3 Audi A3 1,046.12 55 £70.40 4 BMW 3 Series 1,014.42 60 £76.80 5 Vauxhall Astra 874.94 48 £61.44 6 Renault Clio 855.92 45 £57.60 7 Ford Fiesta 821.05 42 £53.76 8 VW Polo 803.08 40 £51.20 9 MINI 639.30 44 £56.32 10 Vauxhall Corsa 606.28 45 £57.60 ...there is a possible answer. :-) At a guess, I think you may be thinking the same as me. It does beg a very important question that has to be really addressed where climate change is concerned: What is real & what is B/S. That question is also made much harder when the "experts" themselves B/S. |

I've worked out that fantastic 1000 miles result! ... That's for driving down from up high in Scotland down south to the sea at Lands End? Or is it for on a rolling road in a test garage?...

Tut tut. :-) The study used the average petrol price of £1.28 per litre as recorded by RAC Fuel Watch for April and calculated the maximum distance using the official fuel tank capacity and maximum combined miles per gallon figures from the car maker.What I would like to know is: What is a maximum combined mpg & how is it arrived at? However, based on this: Based on the number of miles covered and the cost of filling the tank, the Focus costs 7.1p per mile to run, ahead of the VW Polo (7.6p) and Ford Fiesta (7.8p).I'm safely assuming that a test range of mileage was done & then pro-rata by total fuel capacity. Still, I have never heard of any car with the fuel consumption of a motorbike (1st ever motorbike was a Honda C90 (6 pint tank) giving over 100 mpg).. So again, what is real & what is false? Earlier on in this thread, I did state that EV versus Fossil Fuel is a contentious debate. Haven't seen anything to date to disprove that statement. |

And before Dull comments on gas price being too high, spare a thought for those outside the U.S. We can't think outside our own country. That's how we're conditioned. So that we can then blame the US leaders we don't like. Capitalize on this good fortune, one word can bring you round ... changes. |

Such a Special One Hey, all that doesn't matter to her is the price of gasoline... she is not so special. For me you can also add: insurance, licensing, registration, depreciation, repossession, maintenance labour, breakdown tows, unrepairable and unnecessary onboard electronics, parking, traffic jams, most road closures, carjackings, speed limits, unnecessary stop signs, unnecessary red lights on some three-ways, and a bunch else. I think Sarge may be in agreement with this list as well. |

I think Sarge may be in agreement with this list as well. As a user of leg power and public transportation, I agree with a lot of this list. I do have to wonder what has happened to gas use in the US since the mid-90s, as well as accidents/mortality since then. Capitalize on this good fortune, one word can bring you round ... changes. |
