Jay Leno behind the wheel of the Tesla Semi: “It’s like driving an office building”

Jay Leno has driven everything. Pre-war racing cars, ten-figure supercars, prototypes the general public will never see. When he climbs into a vehicle and drops a comparison, it isn’t filler — it’s a synthesis.

On May 8, 2026, MotorTrend publishes its review of the production version of the Tesla Semi Long Range. Massively shared by Sawyer Merritt on X, the clip goes viral within hours. And the line that sticks is this one: “It’s like driving an office building.”

No thrilling 0-100. No power curve. Just an absurd image that, when you think about it, sums up the experience better than any spec sheet.

“It’s like driving an office building”: the quote that sums it all up

To understand why this sentence matters, remember who Jay Leno is. Former host of the Tonight Show, owner of more than 180 vehicles, he is no stranger to references. When he says something is quiet, it’s because he has heard rotary piston engines at full throttle. When he says it’s stable, it’s because he has felt 1930s chassis twist beneath him.

So “an office building” — massive, silent, air-conditioned, stable — doesn’t sound like a criticism. It sounds like a truth.

The central driving position, inherited from aircraft cockpits, places you in the middle of the front axle. The visibility is panoramic. There is no diesel vibration travelling up through your lower back. No dull rumble in the background. Just silence, the road, and ten tonnes of truck responding exactly as you ask.

That’s it, the office building. A place where you work quietly — except it’s moving at 100 km/h on the highway.

A 10-ton behemoth that accelerates like a sedan: the cognitive dissonance

The problem with the Semi is that your brain refuses to believe it. 10,400 kg unladen. A tri-motor 800 kW powertrain. And yet, when you press the pedal, something feels off — in the best possible way.

A classic semi diesel revs up slowly. It growls. It heats up. You wait for the mechanics to wake up before getting any response. Here, the electric torque is available from 0 rpm. The instant acceleration of the Tesla Semi doesn’t give your brain time to recalculate.

Leno sums it up well: manageable despite the dimensions, predictable, reassuring. Not the kind of impressions you’d spontaneously associate with a Class 8.

What 48V architecture really changes

Under the hood (so to speak), the Semi runs on a 48-volt architecture — compared to 12V on virtually all conventional vehicles. In practical terms, to carry the same amount of power, you need much thinner wires. Less weight, fewer losses, better long-term reliability.

This is not a cosmetic detail. It is a platform choice that permeates Tesla’s entire strategy — and the steering actuators that Tesla has also deployed on the Cybertruck are a direct illustration of this. The Semi and the Cybertruck share a technological lineage that says a great deal about the direction being taken.

500 miles, 30-minute charge, $0.15/mile: the numbers that speak to decision-makers

Let’s move on to what convinces fleet managers — not Jay Leno, but the people who sign six-figure purchase orders.

• Announced range: 500 miles (~800 km) in Long Range — consistent with the majority of North American long-distance transport cycles
• Megacharger recharge: 60% in 30 minutes — just enough time for a regulation meal break
• Real-world consumption: under 1.7 kWh/mile — remarkable for a vehicle of this weight
• ePTO 25 kW: the electric power take-off that powers refrigeration without the engine idling — a compelling argument for refrigerated transport
• Projected operating cost: $0.15/mile vs. ~$1/mile for diesel — the knockout argument for a 5-year TCO

Regenerative braking also extends the life of the brakes as a bonus — a significant maintenance item on vehicles in this category.

The Megacharger network: where do things really stand?

This is the friction point. The Megacharger infrastructure exists — but it has been deployed primarily along the Pepsi/PepsiCo corridors, the Semi’s first customers. Outside these established routes, coverage remains embryonic.

For independent fleets that do not travel on pre-configured routes, the question of the network remains open. This is not unlike the importance of battery pre-conditioning before a fast charging session — a technology built into the Semi, but which is useless if there is no charger at the end of the journey.

What Leno doesn’t say: the real limits of the Semi

A good article doesn’t advertise. Here is what still doesn’t work.

The real-world range at maximum load (80,000 lbs / ~36,000 kg) is far from the advertised 500 miles. Field estimates hover around 300 to 350 miles depending on conditions — terrain, temperature, payload. For mountain or winter hauling, the equation changes.

The purchase price hovers around $290,000. Without IRA tax incentives, the TCO loses much of its appeal. And these tax credits are a political variable — fleets planning over 7 to 10 years are playing with an unknown.

The Megacharger network insufficient for operators outside corridors, maintenance concerns for independent operators, access to parts still unclear — we are clearly in an early adopter phase, not a mature market.

From Pepsi to large fleets: where does deployment really stand?

Pepsi remains the emblem of the Semi rollout. Feedback from west American corridors is positive — drivers appreciate it, the savings are real on established routes.

Production is based in Sparks, Nevada, in a dedicated 158,000 m² facility. Tesla’s stated goal: 50,000 trucks per year, representing approximately 20% of the North American Class 8 market. Amazon, Walmart, and UPS are in the testing phase or awaiting delivery.

And that’s where Leno’s quote takes on an unexpected dimension. This isn’t a Tesla press release. It’s a credible, independent man, driving a truck and saying what he feels. This mainstream visibility goes far beyond the circle of fleet buyers — it plants the Semi firmly in automotive culture.

The Semi is no longer a concept. It is no longer a prototype rolling through presentation videos. It is a product delivering goods, today, on real roads. As industry experts point out, the real question is no longer whether it works — it is how quickly the heavy transport market will shift, and who will be ready when it does.
