It’s significantly more challenging compared to crafting an efficient electric vehicle. Therefore, if you believe plug-in hybrid vehicles offer a simple solution, reconsider your position.
Just make
plug-in hybrids
It’s clear. Straightforward, even. It’s
the
solution. By reading various forums, social media posts, and comments, you will likely come across this realization. Automotive manufacturers appear convinced. From Ram to Chevy to Nissan, everyone is joining this trend.
The main significant problem with this idea is that developing a plugin hybrid vehicle is extremely challenging. It’s actually more difficult than crafting an excellent electric vehicle. Those underestimating the complexity and assuming they can easily create a top-notch PHEV are mistaken.
The problem is straightforward: the solution is complex. If your aim was to create a vehicle, you wouldn’t end up with anything simpler than one requiring a gas engine, electric motors, a large battery for solo operation, a charging mechanism, a gearbox, along with sophisticated software and adjustments needed to integrate these components seamlessly.
No surprise then that many end up having a texture similar to creamy peanut butter.
Lexus and Toyota have mastered the creation of smooth, dependable plug-in hybrid electric vehicles (PHEVs). However, not all companies have managed to achieve this feat.
Just ask
Consumer Reports
The typical PHEV experienced 70% more issues compared to the
standard gasoline vehicle in its most recent reliability survey
That’s a poorer performance compared to electric vehicles, which still experience 42% more problems overall than gasoline-powered ones. However, this represents a significant enhancement from last year when plug-in hybrids reported having 146% more issues than both conventional gas and hybrid models.
While the BMW X5, Kia Sportage, and Lexus NX PHEVs exhibit average reliability, their conventional counterparts are more dependable.
Consumer Reports
said. For more proof,
check out the Mazda CX-90 that I’m piloting this week
It’s an attractively crafted SUV from a brand known for consistent dependability. However, it was completely new for the 2024 model year.
According to the report, “The Mazda CX-90 PHEV stands out as the least dependable three-row SUV due to problems related to the hybrid battery, electrical components, and air conditioning systems. It’s noteworthy that this vehicle features an exclusive engine, plug-in hybrid electric system, and rear-wheel-drive configuration—all engineered entirely from scratch.”
A contributing aspect to this problem is that new products often exhibit lower reliability compared to well-established designs—a common observation that also sheds light on numerous electric vehicle concerns. However, the added intricacy of plug-in hybrid electric vehicles further intensifies this issue.
Now, Mazda has
resolved numerous concerns with the CX-90 through various updates and service advisories.
And the one I’m operating feels much more refined compared to the initial prototypes mentioned in the reports. Still, this instance serves as a valuable lesson.
The Mazda CX-90 PHEV that I’m test-driving this week.
It’s just incredibly difficult to get this technology right on your first go. Unlike
extended-range electric vehicles (EREVs)
, PHEVs lack sufficient electric performance to completely decouple their engines from the wheels. Achieving this simplifies design because you don’t have to concern yourself with integrating two incompatible power sources or managing the transition between them.
EREVs face their own set of challenges, as detailed by Kevin Williams in his comprehensive explanation about the Ram 1500 Ramcharger’s battery.
)
PHEVs must integrate both their engines and brake systems similar to traditional hybrids. However, unlike standard hybrids, PHEVs require sufficient capability to operate solely on electric power over considerable distances without activating the internal combustion engine. Additionally, they necessitate built-in charging mechanisms to transform incoming alternating current from an external source into direct current suitable for powering the vehicle’s batteries.
This implies that you require all the intricate components of an electric vehicle along with all the complex parts of an internal combustion engine. Enhancement occurs solely through adding elements. Therefore, although an EV might become easier to manufacture after overcoming initial challenges, plug-in hybrid electric vehicles will consistently remain more difficult to construct and accommodate compared to conventional gasoline-powered automobiles.
This clarifies that although hybrid vehicles have reached nearly equal pricing with conventional gasoline-powered models, plug-in hybrid electric vehicles (PHEVs) continue to be significantly pricier. The CX-90 I am test-driving begins at approximately $12,000 above the price of the gas model, and out of this amount, only about $7,500 can be reduced through tax incentives, but solely when leased.
REEVs such as the Ram 1500 Ramcharger provide the adaptability of PHEVs without requiring the gasoline engine to drive the wheels directly. This allows for reduced calibration efforts and fewer complex parts, including the transmission.
This is not unusual. In July, the average price of a PHEV stood at just below $63,000.
according to
Business Insider
.
That exceeds the average transaction price for all new vehicles sold that month by more than $14,000.
$48,401 per
Kelley Blue Book
That’s anticipated. The surprising part is that it was approximately $4,400 more than the typical selling price of a fully electric vehicle during the same period.
This stems from their inherent complexity. Plug-in hybrid electric vehicles (PHEVs) are more challenging to manufacture and come with lower overall reliability, which increases warranty costs as well. Additionally, they present a significant challenge when it comes to calibration and tuning.
PHEVs need to manage the shift between the consistent, linear power delivery of their electric motors and the uneven torque output of their internal combustion engines. This adjustment should happen almost instantly, regardless of speed, as drivers continuously modulate the accelerator pedal.
They need to swiftly cut off power to the internal combustion engine to conserve fuel and rapidly restart it once the torque requirement surpasses what the electric motors can provide. They have to maintain the engine within its optimal performance zone without allowing it to run monotonously at one speed, as this is unpopular with consumers. This presents quite a challenge.
Last year, I drove a Hyundai Tucson PHEV and really enjoyed it.
Numerous businesses have mastered this approach. I’ve tested plug-in hybrid models from Toyota and the Hyundai Motor Group, which encompasses Kia, and found them to be impressive.
Chevy Volt
It was delightful. The BMW system particularly stood out during my drive of the X5 PHEV; others found it challenging at first before mastering it. Early plug-in systems from Volvo felt rough and irritating, yet their latest offerings have improved significantly. Initially, Mazda’s CX-90 and CX-70 faced difficulties with their systems, but they now operate much more smoothly.
However, many more have not bridged this gap. Despite producing numerous plug-in hybrid electric vehicles (PHEVs), Stellantis faces challenges as some models perform smoothly while others do not, often suffering from reliability problems. Although General Motors excelled with the first generation of the Volt, the second-generation vehicle was developed nearly ten years ago. Consequently,
GM recently announced last year that it was reinvesting in plug-in hybrid electric vehicles (PHEVs).
We will find out if the expertise needed to create quality products endures through that period.
Audi has also achieved some success, but
Volkswagen’s push toward PHEVs
The effectiveness remains unverified. Subaru’s plug-in hybrid Crosstrek also failed, featuring an underwhelming electric powertrain that often needed assistance from the gasoline engine.
The upcoming hybrid variants of Subaru’s Forester and Crosstrek will be standard hybrids lacking a plug-in capability. Although Ford’s Plug-In Hybrid Electric Vehicles (PHEV) might offer superior performance, it’s difficult to make a definitive judgment. Despite the significant number of Escapes, Mavericks, and F-150 Hybrids sold by the company—which frankly feels excessive—Ford’s PHEVs haven’t made much headway in the market.
The Escape Plug-in Hybrid performed reasonably well, whereas the C-MAX PHEV was primarily introduced as a compliance vehicle. Although the brand heavily promoted the plug-in hybrid variants of the Ford Explorer and Lincoln Aviator upon their release, these models were eventually phased out without much fanfare.
quality problems of their own (which weren’t exclusive to the hybrid versions)
.
The Volt was the original plug-in hybrid. Too bad GM killed it before PHEVs caught on.
This does not imply that PHEVs represent a poor solution or an inevitably failed approach.
Given my limited Level 1 slow charging capability at home and the frequent nature of my road trips, a Plug-in Hybrid Electric Vehicle (PHEV) could be ideally suited for my needs.
Still, I observe numerous individuals behaving as if they offer an effortless fix. Let me clarify this once and for all: they represent a solution—one we will require. However, if your aim is to create an exceptional PHEV, it demands far greater effort compared to developing a top-notch EV.
Those who place large bets on them before ironing out the issues face a lengthy and difficult journey ahead.
