    I got good mpg out of my petrol, about 48-50, but I get well over 60 in my diesel, and unless diesel costs over 20% more than petrol, which it doesn’t, it should be pretty simple maths. Plus the diesel is the same on insurance, it’s more powerful, and the torque is nearly 300nm, vs 160 in my last petrol.

    I really don’t see why diesel isn’t more popular. Since when does the average driver care about an emissions scandal rather than cost?

      Diesel fuel used to always be cheaper than petrol in the UK. The UK government increased the tax revenue on diesel fuel to make diesel cars less popular!!

      ​@@AJGGs007no, North Sea oil is light grade suitable for petrol, but cannot be used for much diesel. Most refined diesel came from Russia until the war, so diesel prices increases more than petrol. UK has refining capacity for petrol. Of course fuels are traded on international markets, but imports cost more.

      Agreed but WhatCar don’t seem to mention this in any EV comparison- in fact I’m surprised they decided to use superchargers for the Tesla (albeit at an inflated rate).

      I think it’s fairly disingenuous to have a conversation about a low cost option for a high mileage driver and not mention the fact that you can charge an EV for 7.5p per kWh, which would reduce your annual fuel bill by *thousands*!

The fact that your speedo overreads has no impact on how much distance you travel per gallon. lazygaming945 didn’t specify an average speed. You can’t extrapolate reduced consumption from that, never mind factoring in how much time he spent at his optimum economical speed (generally a constant 50-60mph with no stop-start). In the case of electric cars any amount of slowing down will create power and improve efficiency.

    diesels are great and stuff. but with the type of driving i am doing for about 350 days a year, they wouldn’t be happy. anyways, glad this test is somewhat fair to EVs by not simply ditching out the price for DC charging and claiming thats the price of driving an EV, despite the EV being fully able to do the trip on home charging. sure, some tarrifs are apperently much lower than the one used to calculate the final price.

    Depreciation is the highest cost (either in cash terms or linked to the HP), in many instances this makes the cost of fuel far less important. For EVs the picture is still developing.

    I think we have forgotten the way diesel has been ruined by complexity. With EGR / dual mass flywheels/ particulate filters – they often fail 50-80k and cost £5k to replace the set. And diesel doesn’t like short journeys because of the complexity.

      Everything else in a diesel car usually works fine, except adblue (urea) systems which cannot handle very low tempeartures with full tank of urea. In a cold conditions adblue tank should be kept almost empty since the liquid freezes at -11’C. Urea tank can be damaged with -20’C if it is full.

    Just a note on how much an EV driver with home charging would actually pay:

    Motorway trip: £4.16
    City trip: £0.65

    Also not sure when this was filmed but 52p is above the peak price you’d pay at Tesla Superchargers now. Most of the day it’s around 38p.

    So £21.12 for the motorway trip.

    Hang on for a cost comparison you need to factor in the basic vehicle cost to purchase , then it’s road tax band , then it’s insurance cost , then it’s fuel costs – plus if the user has purchased solar to charge the car that needs to be considered.

    1. @synthmaker Avatar
      @synthmaker

      What really matters is monthly cost of ownership, for almost everybody the best choice will be an EV ( actually a Tesla due to the Supercharge network, high range, high efficiency etc ), specially around London where you have ULEZ and congestion charged. Most people don’t know that parking in central London on the street with an EV will cost you less than £2 for a full day. With electricity cost at 7.5p/kWh, it’s not worth installing solar unless you want some resilience. In the UK power cuts are really rare, I can probably remember 1 or 2 in the last 30 years.

    Excellent comparisons 👌. All have their pros and cons depending on the individual needs of their owners. For my needs, a small engined light weight petrol car is the best solution at this time…enter the Dacia Sandero. Cheap to buy, run and economical with the only real negative, running it will never he as environmentally friendly as an electric car. I would never recoup the additional costs of a diesel powered car nor the initial outlay required for an electric powered one. From this video what does seem apparent with electric powered vehicles is that unless you have the option to charge them at home, they will be no cheaper and in many cases much more expensive to run than the vehicles they are supposedly replacing 🤔.

      Good points however if the Tesla had been charged at home on cheap rate, it would have cost about £6.00 for that longer journey and would cost a lot less in servicing, not thrown any poisonous gas out the back, and been a safer car to boot. Not to mention that it will be compatible with self driving and is able to have over the air updates and a brilliant charging infrastructure and it would be quieter and much faster and smoother.

It will need upgrading soon of course, but I can’t help but feel, the constant need for everyone to have their cars upgraded – the manufacturing and recycling/scrappage alone of the huge turnover of cars is worse for the environment than my little 206 2.0… I could be wrong but that’s why I don’t feel guilty at all right now.

It’s by far the cheapest car I’ve ever owned after 5 yesrs taking into account ‘fuel’,, charging at home most of the time reduced taxes, cheaper parking rate, next to no maintenance cost.

That’s a 36% drop in price whereas the diesel 5008 new is £36,378 and a one year old with 20k miles is £28 ,598. That’s a 17% drop in price.

      Those numbers doesn’t mean anything, unless you actually sell your 1 year old car. If you plan to use it for a long time, depriciation will probably be much closer. And if buying a used care is an option for you, fast depreciation can actually be very attractive, since you can buy a 1 year old model Y at a much lower price. So it’s not the numbers what are important, but making the good decision for you.

    Between 1999 and 2004 I owned a VW Beatle Diesel car. My mpg was 42mpg in city and 50 mpg on the highway. In addition because of the torque provided by the diesel engine in the Co. mountains the diesel delivered smooth pulling power which resulted in steady speed when going up the steepest grades.
