Ahead of initial production scheduled for 2024, electric RV startup Lightship is offering a peek behind its solar electric curtain, detailing the efforts that went into its flagship L1 towable trailer to ensure it arrives as the more aerodynamic option on the market.
Lightship is a San Francisco, CA, and Boulder, Colorado-based startup that heralds itself as the first all-electric RV company – designing battery-powered trailers for the all-electric age. It was founded in 2020 by Ben Parker and Toby Kraus – two industry veterans with notable tenures at Tesla.
We have followed Lightship since its inception, through to the official unveiling of its L1 electric RV trailer at SXSW this past March. This travel trailer is unique in its aerodynamic, modular design and comes equipped with its own all-electric powertrain and battery pack, alleviating the towing capacity for the vehicle in front of it.
The result is a towable EV that will empower future owners to drive further and more efficiently without recharging as much. The L1’s debut last spring did not disappoint, but we have admittedly been left craving more details as an electric trailer that maintains its towing vehicle’s range has the makings to be an absolute game-changer in a stale RV industry.
Today, Lightship shared details of the L1’s development process – particularly the keen focus its creators put on aerodynamics – as it works to deliver a true one-of-a-kind electric RV.

As you’ll learn about in the video from Lightship below, the startup simulated thousands of hours in a virtual wind tunnel using advanced modeling software and help from Angus Locke, who was the lead aerodynamicist on the Tesla Roadster.
This cost-saving technique helped Lightship analyze the airflow behavior around competitor trailers and compare it to its own electric RV designs, enabling its final concept. The startup’s founders also gathered their experience in passenger EVs to develop L1’s unique “Dual Mode” design, which allows for a roomy cabin with 7’6″ of headroom when parked in “Camp Mode” before telescoping its hard-sided walls down to “Road Mode,” thus reducing the Coefficient of Drag and Frontal Area by 35-40%.
Lightship goes on to point out three specific areas it optimized the L1 electric RV trailer:
Tongue Box: The trailer’s ever-so-important leading edge – dictating how the air interacts with the rest of the object downstream while in motion. The L1 features a storage box that helps stabilize the flow around the front of the vehicle while helping reduce the differential between the vehicle towing in front of it, regardless of whether it’s an EV or an ICE truck.
Boat-tailed Rear: Shallow angles at the back help avoid inducing strong vortices, which can increase drag while maintaining the central portion of the cabin to ensure a queen-size bed can still fit.
Electric Powertrain: The star of the show. Lightship’s L1 Long Range RV comes equipped with its own electric motor and battery, propelling itself while reducing the load on the tow vehicle and resulting in improved range.
R&D is vital in this process as Lightship looks to deliver a slam dunk on its first attempt to enter the RV market. However, simulations and computer designs can only go so far. At some point, real-world testing is necessary. To truly put the L1’s aerodynamics to the test, it towed an Essential version (no electric powertrain) 60 miles at a 60 mph pace using three different vehicles: a Rivian R1T pickup, R1S SUV, and gas-powered Ford F-150. For added comparison, Lightship also towed a “bullet-shaped trailer. Here are the results:
Configuration
R1T EV
R1S EV
F-150 Gas
No Trailer
2.17 mi/kWh
1.97 mi/kWh
23.2 mpg
“Bullet Trailer”
0.93 mi/kWh
0.96 mi/kWh
10.2 mpg
L1 Essential
1.26 mi/kWh
1.33 mi/kWh
14.4 mpg
L1 vs. “Bullet”
0.33 mi/kWh (+35%)
0.37 mi/kWh (+28%)
4.2 mpg (+29%)
Overall, the L1 is more efficient than its competitor, regardless of whether the towing vehicle is electric or combustion. Keep in mind that the data above does not account for the L1 Long Range, which promises to offer near-zero range loss thanks to its own drivetrain system.
Current electric pickup and SUV owners are seeing huge cuts to range when towing, making long trips with a trailer more difficult than a traditional ICE vehicle. However, Lightship’s L1 RV has solved that issue, even without its electric motor.
The Lightship L1 is currently available for pre-order with $500 down and is priced between $125,000 and $151,500, depending on which version you opt for. Production is expected to begin in late 2024.

Mitsubishi is partnering with Ample and Yamoto Transports to deploy an innovative new battery swap network for electric cars in its Japanese home market — but it’s not just for electric cars. Mitsubishi Fuso commercial trucks are getting in on the action, too!
Despite a number of early EV adopters with an overdeveloped concept of ownership, battery swap technology has proven to be both extremely effective and extremely positive to the overall EV ownership experience. And when you see how simple it is to add hundreds of miles of driving in just 100 seconds — quicker, in many cases, than pumping a tank of liquid fuel into an ICE-powered car — you might come around, yourself.
That seems to be what Mitsubishi thinks, anyway, and they’re hoping they’ll be your go-to choice when it’s time to electrify your regional and last-mile commercial delivery fleet(s) by launching a multi-year pilot program to deploy more than 150 battery-swappable commercial electric vehicles and 14 modular battery swapping stations across Tokyo, where the company plans to showcase its “five minute charging” tech in full view of hundreds of commercial fleets and, crucially, the executives of the companies that own and manage them.
How battery swap works for electric trucks; via Mitsubishi Fuso.
A truck like the Mitsubishi eCanter typically requires a full night of AC charging to top off its batteries, and at least an hour or two on DC charging in Japan, according to Fuso. This joint pilot by Mitsubishi, Mitsubishi Fuso Trucks, and Ample aims to circumvent this issue of forced downtime with its swappable batteries, supporting vehicle uptime by delivering a full charge within minutes. The move is meant to encourage the transport industry’s EV shift while creating a depository of stored energy that can be deployed to the grid in the event of a natural disaster — something Mitsubishi in Japan has been working on for years.
The pilot is backed by Tokyo Metropolitan Government’s “Technology Development Support Project for Promoting New Energy,” with local delivery operator Yamato Transport testing swappable EVs for delivery operations on both its eCanter light-duty trucks and Mitsubishi Minicab kei-class electric vans.
Electrek’s Take
Fuso eCanter battery swap; via Mitsubishi.
Electrifying the commercial truck fleet is a key part of decarbonizing city truck fleets – not just here in the US, but around the world. I called the eCanter, “a great product for moving stuff around densely packed city streets,” and eliminating the corporate fear of EV charging in the wild just makes it an even better product for that purpose.
Here’s hoping we see more “right size” electric solutions like this one (and more battery swapping tech) in small towns and tight urban environments stateside somewhat sooner than later.

After becoming the first European brand to offer fully electric versions of every model it sells — and at the same price as the ICE models — Opel is going even further, with a new, AWD electric SUV that should give American Jeep fans hope for a new electric Cherokee!
Now part of the Stellantis, rather than GM portfolio of brands, Rüsselsheim-based Opel showed off the first official pictures of its new Opel Grandland Electric AWD — the company’s first all-electric SUV to feature the “Blitz” performance emblem and all-wheel drive.
“Our top-of-the-range Grandland SUV is a milestone for Opel,” says Opel CEO Florian Huettl. “Customers already have a choice of battery-electric drive, plug-in hybrid and hybrid with 48-volt technology. We are now offering even more choice with the Grandland Electric AWD and thus ensuring that our customers can enjoy maximum efficiency and safety in diverse weather and road conditions, combined with plenty of driving fun.”
Stellantis gets it right in Europe
Opel says its new, AWD Grandland is its most aerodynamically efficient model yet, with a drag coefficient (Cd) of just 0.278. That efficiency, paired with similarly efficient electric motors and a 73 kWh li-ion NMC battery give the electric crossover a 501 km (311 mile) WLTP range, while a combined 325 hp and 375 lb-ft of torque should make for suitably spirited acceleration to go along with all that green cred.

Suspension and handling, too, are promised to deliver on what Opel claims is a “typical” Teutonic driving experience in the Grandland AWD:
Both driving pleasure and comfort are further emphasized by dampers with frequency selective damping technology. This unique technology comes as standard on the Grandland Electric AWD and incorporates a second hydraulic circuit in the damper chamber to mechanically adapt the damping force in relation to the frequency. Depending on the situation, road surface conditions and driving style, it enables different damping characteristics for comfortable gliding at high frequencies – i.e. with short impacts such as on cobblestones or a manhole cover – as well as for a sporty, ambitious driving style with more direct contact with the road at low frequencies. The Grandland reacts even more immediately and directly to any command from the driver and, as is typical for Opel, remains stable when braking, cornering and at high speeds on the Autobahn.
OPEL PRESS RELEASE
The Opel Grandland Electric AWD ships with four standard drive modes that include “normal,” eco, sport, and 4WD mode, which simulates locking axles and true 4×4 off-road performance. The ESP and traction control systems adopt specific settings to enhance grip in 4WD mode as well, and maximum power and torque are instantly available.

Like a 90s “gifted” kid that was supposed to be a lot of things, the electric Jeep Wagoneer S never really found its place — but with dealers discounting the Jeep brands forward-looking flagship by nearly $25,000, it might be time to give the go-fast Wagoneer S a second look.
Whether we’re talking about Mercedes-Benz, Cerberus, Fiat, or even Enzo Ferrari, outsiders have labeled Jeep as a potentially premium brand that could, “if managed properly,” command luxury-level prices all over the globe. That hasn’t happened, and Stellantis is just the latest in a long line of companies to sink massive capital into the brand only to realize that people will not, in fact, spend Mercedes money on a Jeep.
That said, the Jeep Wagoneer S is not a bad car (and neither is its totally different, hideously massive, ICE-powered Wagoneer sibling, frankly). Built on the same Stellantis STLA Large vehicle platform that underpins the sporty Charger Daytona EVs, the confusingly-named Wagoneer S packs dual electric motors putting out almost 600 hp. That’s good enough to scoot the ‘ute 0 to 60 mph in a stomach-turning 3.5 seconds and enough, on paper, to convince Stellantis executives that they had developed a real, market-ready alternative to the Tesla Model Y.

With the wrong name and a sky-high starting price of $66,995 (not including the $1,795 destination fee), however, that demand didn’t materialize, leaving the Wagoneer S languishing on dealer lots across the country.
That could be about to change, however, thanks to big discounts on Wagoneer S being reported at CDJR dealers in several states, according to our friends at the Car Dealership Guy podcast.
Jimmy Britt Chrysler Dodge Jeep Ram in Georgia, has a Wagoneer S with an MSRP of $67,590 listed at $43,104 ($24,486 off)
In Florida, Taverna Chrysler Dodge Jeep Ram Fiat has a $67,590 Wagoneer S slashed to $43,138 ($24,452 off)
Chris Nikel Chrysler Jeep Dodge Ram Fiat in Oklahoma has a Wagoneer S listed for $43,425 ($24,165 off)
“Stellantis bet big on electric versions of iconic American brands like Jeep and Dodge, but consumers aren’t buying the premise,” writes CDG’s Marcus Amick. “(Stellantis’ dealer body) is now stuck with expensive EVs that need huge discounts to move, eating into already thin margins while competitors focus on [more] profitable gas-powered vehicles.”
All of which is to say: if you’ve found yourself drawn to the Jeep Wagoneer S, but couldn’t quite stomach the $70,000+ window stickers, you might want to check in with your local Jeep dealer and see how you feel about it at a JCPenneys-like 30% off!
