Approximately a week after a Falcon Heavy side booster – the first of two – arrived at SpaceX’s LC-39A launch complex, a sign of late-stage preparation for the massive rocket’s second and third launches, a Falcon Heavy center stage was spotted rolling through the Waco, Texas locale on its way to SpaceX’s McGregor testing facilities.

Signified by the outlines of unusual bumps under the Falcon booster’s protective shrink wrap, this probable Falcon Heavy center core’s Texas arrival indicates that SpaceX has most likely completed static fire testing of both side boosters, with the second booster now likely to depart McGregor and/or arrive at SpaceX’s Florida facilities in the coming weeks.

In February 2018, Falcon Heavy took flight for the first time ever, bringing to an end an almost mythical series of delays that pushed the rocket’s debut back more than five years. Aside from the unintentional demise of Falcon Heavy Flight 1’s center core, the inaugural launch was a spectacular and technologically valuable success, perfectly verifying the rocket’s ability to safely ignite, launch, separate, and recover two Falcon 9-class boosters simultaneously. SpaceX also took the opportunity – a payload with no practical value aside from inspiration – to perform a successful six-hour coast of the Falcon upper stage, demonstrating a capability critical for many potentially valuable launch contracts.

Now verified by planning schedules, SpaceX plans to attempt a truly impressive feat in the first half of 2019. Assuming all goes well during the center booster’s static fire and the subsequent integration and static fire of all three first stages, the company intends to launch the same Falcon Heavy hardware (all three boosters) twice in as little as two months, currently tentatively penciled in for February/March and April 2019.

Corroborated a few weeks ago by a NASA official involved in one of the payloads that will be present on that planned April launch, SpaceX plans to attempt recovery of both the side boosters and center core and rapidly refurbish them after their first launch in February or March, nominally placing the 6000 kg (~13,200 lb) Arabsat 6A satellite into a high-energy orbit. Perhaps as few as 4-8 weeks later, the rocket will be reintegrated, perform a second static fire at Pad 39A, and launch once again with a USAF rideshare known as Space Test Program (STP) 2, a program specifically designed to allow the Air Force to support low-risk test launches of unproven rockets.

Even more so than the fact that an ~8-week Falcon Heavy turnaround would simultaneously break SpaceX’s previous booster turnaround record in triplicate, the biggest reason to be skeptical of these plans is the fact that this schedule appears to require that the USAF fly a mission on not one but three flight-proven Falcon boosters. This stands at odds with the military branch’s unwillingness (by all appearances) to so much as allow a brand new Falcon 9 enough propellant margin (typically just a few percent) to land itself after the December 23rd launch of GPS III SV01, let alone allow their satellites to ride on a previously-flown rocket.

 

The major wrench in the machine here is the fact that GPS III SV01 most likely cost the USAF upwards of $700M to procure and will ultimately become a critical part of a widespread infrastructural upgrade, whereas STP-2 features two dozen or so small satellites worth dramatically less than the single GPS satellite SpaceX launched last month. STP-2 also operates under a program that is in large part meant to offer opportunities for new or wholly unproven launch vehicles (like Falcon Heavy) to conduct experimental launches, carrying the assumption that certifying those rockets for national security space (NSS) missions would be in the best interests of the Air Force and DoD.

As such, the back-to-back Falcon Heavy launch schedule is by no means impossible despite the fact that it offers up many reasons to doubt its plausibility. Either way, the fact that the next Falcon Heavy’s center core has already left SpaceX’s Hawthorne factory – following in the footsteps of two new side boosters – is a nearly unequivocal sign that the rocket’s second launch rapidly approaching.

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.

In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:

“It’s like driving an office building.”

The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.

Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.

“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.

Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.

Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.

Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.

Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.

Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.

Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.

Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold

Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.

Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.

The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.

Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.

Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.

Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.

The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.

Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.

Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators

A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.

A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.

The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.

Here is a direct comparison of the two versions based on the CARB filing and published specs:

Tesla Semi Spec Long Range Standard Range
Battery Capacity 822 kWh 548 kWh
Battery Chemistry NCMA Li-Ion NCMA Li-Ion
Peak Motor Power 800 kW 525 kW
Estimated Range ~500 miles ~325 miles
Efficiency ~1.7 kWh/mile ~1.7 kWh/mile
Est. Price ~$290,000 ~$260,000
GVW Rating 82,000 lbs 82,000 lbs

The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.

Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
