My wife has a 2023 Jazz Hybrid .. complicated yea but does 67 mpg even around town
These days if your family car doesn't do at least 50mpg (if you stick to the speed limits) then you either have the wrong car or want to waste money. So actually petrol cost in miles per £ is cheaper than ever.
A pity the cheap electric cars look like they will not be available so as to protect western manufacturing which is lagging behind. T introduced a 25% tax and now B has upped it to 100% in the US on Chinese imports. Expect protection here also.
Renault Zoe is very old technology.
IMHO mpg be it 25 mpg or 50 mpg is not the main cost of car ownership so it has never been a factor for me - we feel it is as its a weekly or monthly cost to fill up with fuel. Doubling your mpg does not halve your true cost per mile of motoring even more so if you drive less than 5k miles in a year (I drive closer to 3k p.a. now).
The largest single costs for most private motorists is depreciation, plus other overheads such as Insurance, maintainence , Mot plus where applicable VED. Then there is the cost of buying a replacement vehicle that has gone up due to inflation. I buy used, I tend to keep a car for at least five years - my record for ownership is 12 years. Increasing maintainence costs tend to be the decider when it comes to change. My current XC40 is the most expensive car I have ever bought in my life by a consderable multiplier (4) - I splashed out as it will be my last one so treated myself after 59 years of motoring.
