Plug-in hybrids (aka PHEVs) have been round for some time now. Meaning the cutting-edge autos of some years in the past are actually coming off leases and ending up on used automobile heaps. A used PHEV might be tempting, particularly with (a minimum of for now) the potential eligibility for a federal tax credit score. However the prospect may trigger extra trepidation than a typical used automobile buy.
PHEVs are extra difficult than combustion automobiles — and have issues patrons aren’t acquainted with. Some high-profile PHEVs have been topic to remembers and suffered reliability points. Battery know-how and the market are additionally evolving. So, we don’t know exactly how PHEVs will age and the way a lot patrons will worth them once they do.
As with all used automobile buy, potential patrons should do their due diligence and reply some important questions earlier than continuing.
How do you propose to cost and drive the PHEV?
The primary pure query when shopping for a plug-in hybrid: do you want one? A plug-in hybrid can seem to be the “better of each worlds” on paper. However principle differs from follow.
The optimum atmosphere for utilizing a PHEV — quick journeys, handy plug entry — overlaps closely with the optimum use case for an EV. Purchaser concern or being unable to purchase the kind of automobile desired (a used three-row household minivan, as an illustration) as an EV stands out as the cause to go PHEV.
Alternatively, if a purchaser has a reputable concern that may preclude an EV — prolonged roundtrip commutes or lengthy highway journeys — a traditional hybrid would probably ship pretty much as good if not higher effectivity, price much less up entrance and be much less of a nuisance.
PHEVs could make loads of sense and be very environment friendly — when you’ll be able to cost them recurrently with common plug entry. Helpfully, patrons don’t want to put in a Stage 2 charger. Many PHEV batteries might be charged in a single day on an ordinary 110V wall outlet. Ideally, the manufacturer-provided charging cable is in working order. If not, patrons can usually buy a third-party transportable charging cable for between $100 and $200.
Is the used PHEV eligible for the federal tax credit score?
For now, a used plug-in hybrid can nonetheless be eligible for a federal clear car tax credit score price as much as $4,000. The car and the client should meet sure thresholds to qualify.
The car have to be offered from a supplier, be priced at or under $25,000 and have to be a minimum of two years out from the calendar 12 months through which it’s purchased (in 2024, it must be the 2022 mannequin 12 months or older). The PHEV’s battery pack will need to have a capability of a minimum of 7 kWh and a GVWR beneath 14,000 kilos.
The federal tax credit score is income-limited for the client. A purchaser might not have earned greater than $150,000 as a joint filer, $112,500 as a head of family or $75,000 as a person.

How a lot battery guarantee does the used PHEV have?
Changing a battery on a plug-in hybrid is a uncommon prevalence. The failure charge on PHEV batteries in autos inbuilt 2016 and later — not counting recalled autos — is “properly beneath one p.c.” But when it’s worthwhile to substitute the PHEV battery, it’s a restore that may price a number of thousand {dollars}. And it’s one thing you’d ideally wish to do beneath guarantee.
PHEVs usually have bumper-to-bumper and powertrain warranties much like these of combustion autos. However many more recent ones even have battery warranties stretching to 100,000 or even 150,000 miles. A battery guarantee is nice for peace of thoughts when shopping for a used PHEV. It also needs to assist shield resale worth on the again finish if the client doesn’t hold the car previous that 100,000-mile mark.
Has the PHEV battery degraded over time?
All batteries degrade over time. However degradation shouldn’t be an excessive amount of of a priority when shopping for a used plug-in hybrid — a minimum of a latest classic one. Car batteries are lasting longer than producers initially feared. Charges of degradation rely upon the person car and aren’t all the time linear. However broadly, a PHEV battery ought to keep within the usable vary (a minimum of 70-80% of its preliminary capability) previous 100,000 miles.
PHEV batteries, specifically, are designed to be resilient. Most PHEV batteries have loads of unused capability. That lets the PHEV battery, consistently being stuffed to 100 and drained to 0, keep inside a contented working vary and place much less stress on the battery.
Vary loss additionally issues much less for PHEVs than EVs. Let’s presume a battery experiences a ten p.c vary loss. An EV providing 225 miles of vary as an alternative of its preliminary 250 miles is a much bigger deal than a 27-mile vary PHEV providing 24 miles earlier than the fuel engine kicks in.
Testing degradation your self will likely be difficult; most sellers gained’t allow you to borrow the automobile, drain the battery with simulated each day utilization, and evaluate it to anticipated outcomes. The dealership ought to have the ability to present a battery well being take a look at to find out the state of the car’s battery. Failure to try this ought to elevate suspicion. So ought to a posted vary determine on a full cost that appears far lower than what it ought to be.

Do you propose to drive your used PHEV in chilly climate?
Like full EVs, plug-in hybrids can lose all-electric vary in extraordinarily chilly climate. Like in EVs, the primary wrongdoer is heating the cabin, which is tough to do effectively. Warmth pumps enable a car to heat the cabin extra effectively. However that know-how is comparatively new for full EVs, not to mention PHEVs.
Some PHEVs use an electrical heater, which saps energy and, consequently, vary from the battery. Different PHEVs don’t have an electrical part for heating and run the gasoline engine when wanted to warmth the car. Both approach, you’ll be able to lose a lot of the effectivity you usually would acquire driving a PHEV, particularly an older PHEV with lower than 20 miles of vary.
Has the used PHEV been appropriately serviced?
Service historical past is important when shopping for any new automobile. A plug-in hybrid might be the worst of each worlds from a service perspective. You have got intricate and costly battery packs and electrical motors like an EV. However in contrast to an EV, you even have all of the shifting components and conventional upkeep required for a combustion car.
Guarantee the vendor has detailed, up-to-date service data and that obligatory providers have been carried out. Like EVs, PHEVs might be tougher on their tires than combustion autos with the extra weight. Make sure the tires are in good situation and formulated to deal with the additional burden from the plug-in hybrid.

Has the PHEV’s software program been up to date?
All automobiles are de facto tech merchandise now. Many fashionable reliability points are going to be software-related moderately than mechanical. You wish to make sure that a used PHEV has put in all of its software program updates and that the interface works accurately.
A more moderen infotainment system — much less prone to be outmoded and extra prone to be supported with updates — is healthier than an older one. The potential to do over-the-air software program updates and not using a journey to the supplier can also be useful.
Conclusion: Must you purchase a used plug-in hybrid?
A plug-in hybrid mustn’t scare used automobile patrons off in a vacuum. Sure, a PHEV will lose effectivity and efficiency because it ages. However so do combustion autos. The anticipated lifespan for the battery isn’t that far off most combustion engines. With due diligence, patrons might be assured about what they’re shopping for. The final word query with a used PHEV isn’t a lot whether or not shopping for one is prudent however whether or not a PHEV is the car you want.
If a purchaser does go for a used PHEV, the perfect technique is to seek out the most recent car with the least put on and tear obtainable inside the finances. PHEV tech has develop into extra succesful and extra resilient in recent times. An extended remaining lifespan means better worth, whether or not which means an extended possession tenure or higher back-end resale worth.
