Tesla Semi can save over $400K vs diesel, but there are big ‘ifs’

Tesla Semi electric truck hero

With the Tesla Semi now rolling off the high-volume production line at a qupted price of $290,000 for the 500-mile version, we ran a full total cost of ownership (TCO) analysis against a comparable diesel Class 8 truck. At current diesel prices of $5.35 per gallon, the results are striking.

The Tesla Semi saves fleets between $147,000 and $404,000 over 5 to 10 years of ownership — but those savings hinge almost entirely on what operators pay for electricity and the price of diesel, which is spiking right now.

New Holland Construction released its first battery-powered mini excavator, the E15X, all the way back in 2023 – but enough of you called CNH to tell them your loads were just too big for the E15X.

Nikola founder and convicted fraudster attacks Tesla Semi with some decent points

Trevor Milton, the convicted fraudster who founded Nikola Motors, took to LinkedIn to attack Tesla Semi’s economics with a point-by-point takedown. Despite his near-total lack of credibility, a couple of his arguments actually hold up.

Milton, who was convicted of securities fraud for lying to investors about Nikola’s electric truck technology, posted a lengthy comment on a LinkedIn post about Tesla ramping Semi production, claiming he “knows EV trucking probably better than anyone.”

NIO delivers 29,356 vehicles in April, but growth slows sharply from Q1 pace

NIO-Onvo-L90-orders

NIO (NYSE: NIO) delivered 29,356 vehicles across its three brands in April 2026, a 22.8% increase year-over-year. The result pushes NIO’s cumulative deliveries past the 1.1 million mark.

The growth rate, however, represents a significant deceleration from Q1 2026, when NIO posted a 98.3% year-over-year surge across 83,465 deliveries — and March alone hit 35,486 units with 136% growth.

Macfox X7 review: A street-legal UL-listed e-bike that feels like an electric moped

I recently got a chance to test out the Macfox X7 electric bike, and after spending some time riding it around, one thing became immediately clear: while this model isn’t trying to be a traditional e-bike, it still sticks the landing with a legal and fun moped-like ride.

And that’s exactly why a lot of riders are going to love it even more.

Tesla reaches 10 billion FSD miles — is there’s a magical milestone for autonomy

Tesla 10 billion FSD miles milestone

Tesla’s Full Self-Driving (Supervised) fleet has crossed the 10 billion mile mark, according to the automaker’s updated safety page. It’s the threshold that CEO Elon Musk himself set earlier this year as the data milestone needed for “safe unsupervised” driving.

The achievement represents a massive acceleration in data collection — the fleet was logging roughly 29 million miles per day by late April, up from 14 million miles per day at the start of the year. But hitting a round number doesn’t mean Tesla is about to flip a switch on Level 4 autonomy.

Segway launches 60 MPH electric dirt bike – and it’s basically a full e-motorcycle

Segway may still be best known for its scooters, but the company has been quietly (and sometimes not so quietly) expanding deeper into the electric two-wheeler space. Between its growing e-bike lineup and earlier Sur Ron-style off-road models, the trajectory has been clear. Now with the launch of the new Xaber 300, Segway is diving headfirst into the electric powersports market.

And make no mistake: this is a motorcycle, not an e-bike or an e-scooter.

1966 Ford Mustang converted into a Tesla with working ‘Full Self-Driving’

Tesla FSD in Mustang

A Tesla auto parts shop owner in Sacramento spent about $40,000 and two years converting a 1966 Ford Mustang into a fully functional Tesla — complete with the Model 3’s dual-motor drivetrain, 15-inch touchscreen, and working “Full Self-Driving” (Supervised).

It’s likely the first non-Tesla vehicle to run FSD, and it achieves 258 Wh/mi — roughly matching the efficiency of an actual Model 3.

This Tesla owner won $10k in court for Tesla’s FSD lies. Tesla is still fighting him.

For over a decade now, Tesla has sold a promise of vehicles that can drive themselves, even stating that every car it produced had all the hardware for self-driving.

But after years of the company being unable to deliver, some owners want their money back. Ben Gawiser is one of those owners, who recently won a $10,600 judgment due to Tesla’s failure to deliver. But Tesla is still fighting to delay payment, even just a few days at a time.

Tesla launches Model 3 RWD in Canada at record-low $39,490 ($29,000 USD) from China

EV gas car gap

Tesla has launched a new Model 3 Premium RWD trim in Canada starting at just $39,490 CAD — a record-low price for the electric sedan in the country. The price, which converts to roughly $29,000 USD, is made possible by sourcing the vehicle from Giga Shanghai instead of Fremont, California.

The move marks the first time Tesla is selling China-made vehicles in Canada since the country imposed a 100% tariff on Chinese EVs back in 2024 — and it creates a massive price gap with the Model 3 Performance.
