A provocative analysis from CleanTechnica on February 19, 2026 asks a question that resonates deeply with Taha Abbasi: are internal combustion pickup trucks reaching a mechanical complexity ceiling that electric trucks don’t face? As someone who has owned, repaired, and tested both ICE and electric trucks extensively, Taha brings real-world experience to a debate that’s usually conducted in spreadsheets.

The core argument is compelling: modern ICE trucks have become engineering marvels of complexity, layering system upon system to meet emissions regulations while delivering the horsepower and torque that truck buyers demand. Each layer adds components that can fail, interactions that create diagnostic headaches, and maintenance requirements that accumulate cost. Electric trucks, by contrast, operate on a fundamentally simpler mechanical platform — and that simplicity is becoming an increasingly powerful advantage.

The Complexity Spiral

Consider what a modern diesel pickup truck contains under the hood: a turbocharged engine with variable geometry turbo, an intercooler, exhaust gas recirculation (EGR) system, diesel particulate filter (DPF), selective catalytic reduction (SCR) system with diesel exhaust fluid (DEF), high-pressure common-rail fuel injection, variable valve timing, and an engine management computer that coordinates all of it. That engine connects to a 10-speed automatic transmission with its own control module, torque converter, and complex valve body.

Each of these systems was added to solve a specific problem — emissions, efficiency, performance — but each adds failure modes, maintenance requirements, and diagnostic complexity. A faulty DEF sensor can put a $70,000 truck in limp mode. A clogged DPF can cost $3,000 to replace. An EGR cooler failure can cascade into a head gasket issue. As Taha Abbasi learned firsthand with his V8 Tundra — documented on his YouTube channel — even simpler ICE trucks require constant attention to a web of mechanical systems.

Electric Simplicity as a Feature

An electric truck motor contains roughly 20 moving parts. A comparable ICE engine contains over 2,000. An electric drivetrain uses a single-speed reduction gear. An ICE drivetrain uses a 10-speed automatic with hundreds of internal components. There’s no exhaust system, no turbocharger, no DEF fluid, no timing chain, no spark plugs, no oil changes, and no transmission service. The regenerative braking system dramatically reduces brake pad and rotor wear, cutting another major maintenance item.

The Tesla Cybertruck takes simplification further with its 48-volt electrical architecture, which reduces wiring harness complexity and weight, and its stainless steel exoskeleton, which eliminates paint shop requirements and corrosion concerns. The Rivian R1T offers a similar mechanical simplicity advantage with its quad-motor architecture that provides precise torque vectoring without the mechanical differentials and transfer cases that ICE trucks require.

The result is a category of vehicles that costs dramatically less to maintain over their lifetime. Taha Abbasi estimates the 5-year maintenance cost difference between a modern diesel pickup and an electric truck at $3,000 to $6,000, depending on usage patterns. For commercial fleet operators running hundreds of vehicles, this maintenance advantage alone can justify the transition to electric, even before fuel savings are considered.

The Real-World Owner Experience

Beyond the raw cost comparison, there’s an experiential dimension that spreadsheets miss. ICE truck owners are familiar with the dreaded “check engine light” — a dashboard warning that could indicate anything from a loose gas cap to a catastrophic engine failure, requiring expensive diagnostic equipment to interpret. Electric truck owners rarely see comparable warnings because there are simply fewer systems that can trigger them.

Oil change schedules, transmission fluid changes, DEF refills, air filter replacements, fuel filter replacements, spark plug changes — the maintenance calendar for an ICE truck reads like a part-time job. An electric truck’s maintenance calendar is largely limited to tire rotations, cabin air filter changes, and brake fluid replacement every few years. As Taha Abbasi has documented, even battery longevity concerns are being addressed by real-world data showing batteries outlasting the vehicles they’re installed in.

Where ICE Still Wins (For Now)

Taha Abbasi is honest about the areas where ICE trucks retain advantages. Towing range is the most significant — pulling a heavy trailer dramatically reduces EV range in ways that don’t affect ICE trucks as severely. Refueling speed at a gas station versus charging speed at even the fastest DC charger still favors ICE, particularly for long-distance towing scenarios. And in extremely cold weather, ICE trucks don’t face the range degradation that batteries experience.

These advantages are real but diminishing. Battery energy density improves 5-8% annually. The Supercharger and fast-charging networks are expanding rapidly. Cold-weather battery management systems are improving with each generation. The gap that ICE trucks exploit is closing faster than most people realize — and the mechanical complexity wall that ICE trucks are hitting isn’t getting any lower. The trend line favors electric. The only question is timing.
