Changing car very soon, hopefully by the middle of next month.

Whatever we get its going to be a Toyota hybrid, but after some advice and someone more mathmatical to double check my back of fag packet calcs.
It won't be a full EV and it will only be a Toyota (or Suzi badged Toyota) due to endless reliable service from every Toyota we're had.

Can get an under 10k miles 25 plate Prius plug in hybrid for £25k, an under 10k miles 25 plate Suzuki Swace (Corolla estate) normal hybrid for £21k.
£4k difference in price, Prius being the 2 litre 223bhp version a far better drive but we lose the estate practicality, either option we can live with.

Plug in has 13.6kwh battery giving roughly 50 miles of electric only driving, otherwise for comparison purposes we're going to assume 50mpg from both vehicles once the plug in battery has exhausted and normal hybrid drive engaged.
The new shape Prius lacks boot and rear headroom so isn't so attractive to the taxi trade as Corolla/Swace hence the rapid depreciation in first year making them quite a bargain for the private buyer.

Our Octopus Intelligent Flux solar tariff pays us a minimum of 22.7p per kwh, given how the solar is performing we're reluctant to change tariffs to a cheap night rate one, which wouldn't pay us anywhere near as well for export.

Back of fag packet reckons just over £3 to charge from empty for those 50 miles on battery only, with petrol fast approaching the £10 gallon so roughly £6/7 difference in cost for every 50 miles we cover assuming we're driving locally enough to charge at home.
Balanced against that is possibly more expensive and complicated battery set up of the plug in if we're still here when the long warranties everntually terminate.

This purchase might be the last car we buy so want to get this right.

Any thoughts please, my O level maths was 55 years ago so make allowances.

Jimbo.

I’d argue that the probability of failure of the PHEV is so low (assuming the HEV bits are identical) that it’s not worth factoring in.

Remember to factor in tax changes going forward.

Self charging won’t incur any change. Plug in hybrid will incur half the new charge of a full EV or thereabouts (can’t fully remember, think it’s 1.5p per mile)

All subject to change and alteration of course. smile

Fair point, i believe if you stay with Toyota annual servicing the battery itself can be covered up to 15 years, presuambly 10 years on the rest of the rest of the system and drivetrain.
Suzi up to 10 years then stop.
Both warranties stop at 100k, which we're unlikely to breach.

Good point, hadn't allowed for that, which depending on who gets in next anything could happen either way.

You might also want to consider a Lexus badged Toyota. I looked at the RAV4 and ended up going with the NX450h+

On pure financial consideration, the PHEV might not make perfect sense, you pay a lot more for it so need to do a lot of electric miles to make it worthwhile. However mine comes with 300ish BHP compared to 200ish BHP for the standard hybrid which is nice, and where you really notice the PHEV is pulling away from a standstill, you have instant power like a BEV rather than a petrol only car, especially one with stop-start, having to start the engine and then select a gear.

Some Toyota specific things:
- They have a CVT, which some people hate because it doesn't sound like conventional gears, you put your foot down and the revs rise straight away and stay high as you accelerate.
- They will maintain about 20% of the battery to allow them to run as a standard hybrid once the charge is depleted. This means the total electric range is a bit shorter than you might expect from the battery size, they're also not as efficient as a BEV when running on battery, I get about 4.5km/kWh in town, driving, and around 60-65 km.
- The EV/HV Auto mode will let you run in EV but will start the engine when you need more power or speed. The point it will start varies depending if you have the car in Eco, Normal or Sport mode.
- Some Lexus have an issue with the 12V battery not getting enough charge, not a major issue but some owners have had the battery replaced under warranty at less than a year old. I don't know if this is also common to Toyota but you might want to have a search.
- Mine has a 6.6kW charger built in, but can't use 3 phase, so on an 11kW charge point only charges at 3.5kW, not really a problem as we charge overnight but it means getting a quick top up at a public charger might be slower than you think, but then again its more than about 45p/kWh it's cheaper to use petrol anyway.

I find I use EV mode around town and switch to petrol to the main roads. Petrol gives me nearly 50mpg at 100kph (Dutch motorways) and mid 40's at UK motorway speeds, not bad for a 2 tonne SUV. For me this is ideal as most of our day to day driving is relatively short range so done on electric, but we've just been abroad on holiday for a week and no need to bother finding chargers as we just use petrol.

Thankyou, I understand the Toyota synergy drive isn't actually a CVT, but behaves like one, in that it doesn't have the moving drive belts normally associated with CVT, but happy to be put right if i'm once again miles from the truth.

Last time i drove a full hybrids was back in 2008 when i stopped driving car transporters, delivered many Prius of the era and was most impressed with the driveline.

We had also considered Suzuki Across (Rav 4 clone), again a PHEV but with 4WD and similar performance to your Lexus, but we're trying to avoid the luxury car VED penalties for the first 5 years, so that rules the big Suzi out, as it does many of the higher spec Prius which even if they get different paint to the standard yellow are likely to be just over £40k, plus we'd rather the lower spec Prius if we go that way due to 17" as against 19" wheels, the extras that the higher spec come with of no interest to either of us.

Our usage similar to yours, my now less frequent (shifted to part time from full time work) commutes and all of our local running could be completed on battery.
We don't have a full electric car charge point, instead when the solar was put in we got the electrician to wire us in a heavy duty external 3 pin outlet, our electric tariff would allow us to charge at any time except 4 to 7pm when we export our remaining stored solar battery power at peak rate, so charging timescale isn't an issue.

Apparently Toyota's Hybrid Synergy Drive has less moving parts than a conventional ICE, hence the reliability. As far as I'm aware the PHEV just gets a bigger battery, bigger motor or two (AWD versions have an extra motor for the back wheels) and the charging gubbins. There's very little extra to go wrong. They call it an E-CVT, with planetary gears rather than belts like some older CVTs, and I believe its also how the engine and electric motor are connected in so no additional transfer boxes or clutches.

Depending on the size you need Lexus also do the LBX and UX, which can squeeze in under the £40k threshold, but not as PHEVs. Shame they stopped making the CT and Toyota don't do a PHEV version of the Corolla. Saloons and hatchbacks seem to have fallen out of favour versus SUVs these days, I guess it makes squeezing in a big battery easier.
A friend has a non plug in CH-R is and is very happy with it, bit quite a small boot on them.

I said before, but anyway. I have now driven my sister in-laws toyota aygo x hybrid 2025 (make over version) Its a Hybrid utilizes a 1.5-liter, 3-cylinder engine featuring a timing chain rather than a belt, designed for enhanced reliability and reduced maintenance. It uses a 5th-gen hybrid system and a specialized eCVT transmission which utilizes a planetary gear set rather than a belt-driven CVT system.

The first thing to note is that is blows hot air imminently and drives nicely and not slow like the preface lift. The MPG was around 85mpg around town and some duel carriageway, trip dependant of course. Not looking and driving car, I must say well impressed.

If you can plug-in at home, then you might as well just get an EV. There's loads of them available for less than £20k now.

Getting a hybrid only works if you cannot charge at home and/or do such long distances, that you cannot afford to stop at all.

You could easily get an EV hatchback, that will be cheaper to run, cheaper to tax and cheaper to fix. Plus more reliable and is actually easier to live with.

Years of reliable durable service puts me firmly in the Toyota family, and we don't want to go full EV.
Thanks for the input, none too sure that over the time we keep ours cars, circa 10 years and the next one possibly till it or we fall apart, that the EVs already on offer will work out cheaper to fix tax or last as long as a Toyota hybrid, you only have to look see what every taxi driver and his dog are cruising around in, they can't all be wrong.

They also have the HRV and that is just as efficient, but I have have not driven one as yet. The CHR sounds pretty cool

I fully understand that. As mentioned, you'll be stung on the 1.5p per mile charge on top of paying a hefty fuel bill.
Granted the Toyotas are solid, I've had and I'm a massive Toyota fan. The reason I went full EV is the cost over a hybrid for running it. Then again I am doing a lot of miles so makes sense for me.

I really like my Ford Kuga Vignale PHEV. It is CVT and even when the engine is running it is just like driving a full EV.

Especially get a PHEV so that you are eligible for an EV electricity tariff so that even with a 3 pin plug granny charger you can also run the dishwasher, washer, dryer and even the hot water immersion heater after midnight at off peak electricity rates. The downside is that I need to be there to plug in and turn on but my bedtime is always after midnight regardless.

Next door had a Puma, they were very pleased with it.

Have to do some workings out re the tariff, Intelligent Flux pays us the same rate for export as we pay for import and we have a sizeable array, we'd need to make a hell of a lot of cheap rate use to make up for the much reduced export rates of any other tariff and we wouldn't normally do enough mileage for the car charging alone, as always circs and siuations change so always keeping an open mind, so far Octopus have left these rates alone where other energy companies have cut the rate, but anything can and probably will happen.

Our choice is fairly well made up so far, choice is really between the Prius plug in and the Swace (Corolla estate), but would appreciate someone casting an eye over my back of fag packet calcs to see if i'm a miles out on my approximate figures.

I think PHEVs are a great gateway drug to a BEV. I didn't go BEV because I was concerned about the number of longer trips we do, often staying with friends of family who don't have chargers, and because I'm currently reliant on public charging (we're supposed to be getting power to the communal garage at some point but I'm not holding my breath). I'd previously rented a Polestar 2 for the weekend and come to the conclusion that certainly in the UK they were only worth having if you could charge at home. Where I live now we have plenty of on street chargers but 43c/kWh isn't a big enough saving over petrol to justify it.
Now having got used to driving a PHEV, I'd happily have a BEV, especially if I had the ability to charge at home on a fraction of what I currently pay for electricity, and take the hit on expensive fast chargers when we're away somewhere.

As a Toyota fan it may be worth taking a look at the C-HR+, lower spec models are a bit under powered compared to a lot of EV's, but decent range and economy.

Given your current solar setup you need to figure out what it will actually cost to charge a PHEV or an EV though, as you're presumably selling excess back to the grid, so you'd lose that if putting it in to a car, but if you have a variable tariff you'd need to work out when best to charge.

3 pin cranny charger is about 2.3 kW, so for my PHEV would add about 10.3km (6.5 miles) per hour charged. BEV's are more efficient, so something like a C-HR+ will gain more like 10 miles per hour charged. Both PHEV and BEV will usually have the ability to set up scheduled charging (ie plug it in but set it not to only charge between whatever hours your rate is cheapest).

I find the easiest way to do the maths is to work it out in pence per mile

If you assume 4 miles per kWh (probably less in winter), then on 22.7p/kWh you're paying 5.675p/mile. Add in the tax that starts in the next year or two and you're up to 7.175p/mile

At current prices of around £1.50/litre, a 50mpg car costs 13.62p/mile. If you assume petrol will drop back down to £1.30 or so that drops to 11.8p, so still about 60% more than electric.

With a PHEV you can work out what it costs to run on petrol and then work out the maximum price it's worth paying for electric at public chargers. For me it's about a factor of 3.5, so with UK petrol at £1.50/litre I know it's not worth paying more than 43p/kWh for electricity.

It's currently €2.30/litre here, so anything under 66c/kWh is worth it, and my local chargers are 43c/kWh so I'm sticking with electric as much as I can!

Possibly the OP as he's on a decent deal selling what his solar has generated.

A lot of people with a PHEV who don't do enough mileage on electric to justify the increased day rate.

Anyone who doesn't do a lot of mileage in general - I probably use less than 14kWh/week in the car.
