Hybrid vs Plug-In Hybrid: The Outlet Changes Everything

PHEV vs Hybrid: Comparison

Hybrids have been around for nearly 30 years. While it was initially used for smaller vehicles, these days, just about every kind of car can be electrified in one way or another. To drive that point home even further, we have hybrid full-size pickups now, something unimaginable about a decade ago.

With hybrids come plug in hybrids that promise to deliver the best of both worlds. You can plug it in like an EV and get a reasonable amount of range, but you don't get the range anxiety associated with full battery-powered vehicles thanks to the engine. PHEVs, on paper, also deliver great fuel mileage, far greater than that of hybrids.

Of course, both have their respective pros and cons, but is one really better than the other? The answer to the whole hybrid vs plug in hybrid debate would be, 'it depends.' Here's why.

Where It's the Same

In terms of configuration, the two drivetrains are practically the same. An engine is paired with an electric motor, and that engine also serves as a generator to keep the vehicle's batteries topped up, maximizing efficiency. Hybrid or plug in hybrid, both are aimed at maximizing fuel efficiency.

Once the battery doesn't have enough juice, the engine kicks in to recharge it, and regenerative braking boosts the charge for more electric range. At the same time, both the electric motor and the engine can work together if greater performance is needed, such as during an overtaking maneuver. Both can drive for a period on pure electric power, especially at lower speeds.

Where It's Different

In case it's not obvious enough, a PHEV can be plugged in and recharged, while a hybrid cannot. But aside from that, PHEVs have larger battery packs than regular hybrids. That means one can drive without the engine kicking in for longer, further boosting MPGs.

A typical hybrid battery ranges from 0.8 kWh to 2 kWh, the latter being a pretty generous size. However, a plug in hybrid battery usually ranges from 10 kWh to 25 kWh, although there are models that come with even larger packs.

Pros and Cons: Hybrids

As the technology has been around for so long, you can bet that hybrids are, indeed, reliable. Data from Consumer Reports does back this up, with 15% fewer problems compared to non-hybrid vehicles. At this point, there's no more doubting the reliability and durability of hybrids, particularly if they're of Japanese descent.

Of course, there are fuel-economy gains over non-hybrid models, but hybrids are a big win for those who frequently travel in highly congested areas. Hybrids thrive in heavy traffic, as they tend to rely more on battery power than on the engine at lower speeds. The constant stops also mean the batteries get some form of charge as you creep along. It's the reason you see these with the same or even higher city MPG ratings than highway MPG.

Downsides? If you're constantly on the highway, then you won't really feel the true benefits of a hybrid. At higher speeds, the small battery drains quickly, and the engine constantly has to step in to keep it charged and the car running. Hybrids are also more expensive than non-hybrid models, and there is a greater deal of complexity compared to purely fuel-fed vehicles. And while hybrids are proven to be reliable, it doesn't mean that repairing them will be cheaper.

Pros and Cons: PHEVs

With batteries up to 10 to 20 times larger than those of hybrids, the clear advantage of PHEVs is EV-only range. That means you can do some trips without ever seeing the engine turn on, or on a longer drive, you can drive a good distance on battery power alone. The less you use the gas engine, the further you can go on a tank.

Plugging it in has its advantages, too. You can have the battery fully charged before setting off, whereas a hybrid will depend on how much charge you had left from the previous drive. Charge it up frequently, and it'll feel like you've unlocked an unlimited fuel cheat code. You can treat it like an EV of sorts, and the engine is there to keep you going once the charge is depleted. If you run out of juice, a PHEV then acts like a regular hybrid. A win-win? Well, not quite.

While it's great that you can drive it like a hybrid, you're not taking full advantage of the benefits if you don't fill up the battery from time to time. Also, you're practically lugging around excess baggage if you keep driving a PHEV on a near-empty battery. Then there's the matter of complexity, and data shows that PHEVs aren't the most reliable vehicles around. For full hybrid vs plug in hybrid reliability, there is one clear winner, and it's not the latter. Yes, dependable ones do exist, but the tech is still somewhat undercooked for some automakers.

PHEV vs Hybrid: Final Thoughts

Whether you're reading this now or a few years later, fuel prices will always be volatile. It may be stable for a couple of months or even years, but it only takes one major event to throw everyone for a loop. With that, making the most out of your mileage is key, and for those still (understandably) apprehensive about going full electric, at least we have hybrids and plug in hybrids. So, which one offers more for the consumer in this plug in hybrid vs hybrid debate?

As it is, hybrids make for great daily drivers, and the advantages that they have over non-hybrid models are as clear as night and day. There's practically no performance penalty these days, and you get great gas mileage in return. City dwellers no longer have to worry so much about wasting fuel while idling in traffic, either. The best part is that there's no shortage of solid, dependable, and reliable choices out there.

A PHEV's advantages aren't as clear-cut as a hybrid's, although you do still get better mileage. It is, after all, essentially still an electrified vehicle, so you'll still feel good about the extra MPGs. However, you'll really have to plug it in even just once in a while to take advantage of the technology. And even if you say you're not after breaking even, given the additional cost of purchasing a PHEV, it's still wasted potential of a vehicle's capabilities.
