Audi apprentices put an electric spin on an iconic classic car. The team “awoke” an NSU Prinz 4 from 1971 from its sleep, charging it up with technology from the Audi e-tron EV.
In honor of the 150th anniversary of its Neckarsulm site, Audi put its apprentices to the task of restoring a classic car with an all-electric drive train.
The Audi Neckarsulm site has produced several of the brand’s top-selling models and began building its first fully electric model, the Audi e-tron GT quattro, at the end of 2020. Over the years, Audi has transformed the site for the electric era with upgrades, including AI and 3D printing, to enhance efficiency and high-voltage battery production.
To commemorate the anniversary, “We wanted to build a car that was not only fast and looked cool,” explained Dean Scheuffler, an apprentice at the site. The NSU Prinz 4 was the perfect match, as it’s been off the road for decades.
The team revealed the NSU Prinz 4 EV, now called the Audi “EP4,” at Audi family day this week. The “E” stands for electric drive, while the P4 is in honor of the NSU Prinz 4, a classic car produced in Neckarsulm by NSU Motorenwerke from 1961 to 1963.

Trainees from the mechatronics, bodywork, vehicle construction mechanics, and painting courses unveiled the restored electric car. As the body and paint specialists worked on the chassis and exterior of the vehicle, the mechanics tackled the powertrain, battery, and suspension.

Fitted with a 240 hp (176 kW) electric motor from a 2020 Audi e-tron at the rear, the EV is eight times more powerful than the NSU Prinz 4’s original two-cylinder gas engine that had 30 hp.
In addition, the team placed a battery from the Audi Q7 TFSI e-quattro plug-in hybrid under the front hood, once home to the fuel tank. The EV “breathes” through an open-air intake at the bottom bumper, while heat can escape through the opening in the hood.
The electric classic car’s tailgate can be fixed into a half-open position to highlight the “electric power plan,” reminiscent of the iconic racing cars based on the NSU Prinz 1000.
The NSU Prinz 4 EV conversion took significant modifications to the chassis and body. Its modified floor plan includes an Audi A1 as a base, including the brakes and axles. Adding muscular fenders from a 3D printer, the team mounted the modified (and significantly widened) body on top.

Apprentice auto painter Cynthia Huster explained, “The eye travels with you! We wanted the EP4’s performance to be visible from every angle.”
The inside has been stripped down to the bare essentials, with all other surfaces painted black, common among racing cars. A single-board computer and screen feature the instruments and displays.
Audi says NSU vehicles made history and continue inspiring car enthusiasts to this day. The automaker claimed, “With its charm and electric drivetrain, the EP4 stirs anticipation for the coming all-electric chapters in the continuing story of Audi’s Neckarsulm site.”
The project gave the apprentices a chance to learn more about how electric cars work and the development process while allowing them to showcase their talent.

The HappyRun G300 Pro is the epitome of an out-of-class electric bike. That is to say, it has many of the components of an electric bicycle, key among them the functional pedals, but its extremely high power and speed place it well outside the limits of traditional e-bike classifications. The result? Basically, an electric motorcycle with pedals. And I’ve got some thoughts about that.
But before I dive into those, this is one of those rides that you’ll want to see in action. Check out my review video below. Then keep reading for the full details.
HappyRun G300 Pro Video Review
HappyRun G300 Pro Tech Specs
Motor: 3,000W continuous and 6,500W peak-rated rear hub motor
Top speed: Up to 50 mph (80 km/h)
Range: Claimed up to 70 miles (121 km)
Battery: 72V 30Ah (2,160 Wh)
Weight: Heavy (well off the scale on my 100 lb scale)
Rear suspension: “Yopi Box” rear spring suspension
Extras: Looks like a Sur Ron or Talaria-style bike, color LED display, included fenders, LED headlight and tail light with turn signals, very nice kickstand, two color options available.
What is this even for?
Despite looking like a bicycle in some regards, I definitely felt wrong using this in the bike lane. That meant for 95% of my road riding, I was simply in the lane like a motorbike. The only times I would use the bike lane were when I could see it was completely empty, and it was basically just a shortcut past the stopped traffic at red lights. And even then, it just didn’t sit right with me. I’m an e-biker and I live a car free life, so the safety of bike lanes is an important issue for me. I’m not going to jeopardize other riders or even make them feel unsafe in the tiny little sliver of asphalt that is supposed to feel like home for us, and so I ride this thing in the road when I’m on the road.
That being said, I don’t even think the road is the right place for this bike. Where it really shines is off-road. Between the long travel suspension, the enduro-style seat, and the unnecessarily high power for commuting purposes, the HappyRun G300 Pro is at home in the dirt and on the trails. In fact, I even enjoyed overlanding on it, going places where trails couldn’t take me. It felt like a great exploring-the-outdoors type of ride!

If you watch my video above, you’ll see that this type of riding, recreational and exploring, is where the HappyRun G300 Pro really came into its own, and I think that’s precisely where it belongs. Just like how Sur Rons and Talarias shouldn’t really be taking over the streets, but instead should stick to the dirt trails they excel at, this is a great bike for that purpose. You’ll also notice in the video that I prefer to wear my motorcycle gear when I ride these types of bikes, and I’d make that recommendation to anyone else. A t-shirt and a bike helmet just don’t feel like enough here.
With that in mind, the included bicycle pedals start to seem superfluous though, and I really only pedaled at slow speeds, or when ghost pedaling because a cop was in the area and I didn’t want to get a bike impounded before I was even done reviewing it. So if you ask me, it doesn’t really need the pedals, and it doesn’t even really need the roads.
What about the build?
The HappyRun G300 Pro is an interesting mix of quality parts and merely acceptable parts. Nothing about it seemed terrible or dangerous, and a few components like the Sur Ron kickstand actually impressed me. But then the use of a bicycle-level handlebar stem and budget-level shocks seems to undercut that message.
On the other hand, the massive 72V 30Ah battery is huge and likely more than most people would need. I’d have preferred to see it being UL-listed, but I guess at least it claims to be underwritten by some Chinese insurance agency. I guess that’s better than nothing?
The geometry actually kind of sticks the landing, at least for me and my 170 cm (5’7″) height. The saddle is plenty comfortable, though my off-roading had me out of the saddle much of the time anyway and letting my legs join the full-suspension to better absorb the terrain.
What’s my verdict?
Here’s the thing: nothing about this bike is top shelf, but it still offers an incredibly fun, solid feeling ride. The power is more than most people need, the speed is faster than most people should ride (especially on trails), and the battery has more capacity than most people would require. So it’s not like they’re cutting corners on performance.
Some components could have been beefed up, and the decision to lean more towards bicycle-level components does make me question what a few years of hard off-road riding could do to this bike. But when used correctly, in an area where the bike is meant to be used (i.e., not where it legally isn’t allowed to be ridden), then it seems to fulfill the role of a fun adventure-style bike. At a price of $2,599 (or $100 off with the code ELECTREK), it significantly undercuts the cost of a Sur Ron or Talaria bike while giving a similar type of ride, even if the components don’t live up to the level of those costlier light electric dirt bikes.
My biggest worry, though, isn’t about the bike, but rather the potential for it to be misused. Look, it’s a fun ride and offered me more performance than I needed for all the different types of riding I tested it with. But like any bike, it has to be used in its element. We don’t blame the hammer if someone hits their thumb while driving a nail, and we shouldn’t blame the bike if someone wraps it around a parking meter. But it also really shouldn’t be used in that kind of environment, and it definitely shouldn’t be used in a way that could put others at risk.
It’s a fun ride for exploring, but this level of power requires some serious personal responsibility. If you’re a parent wondering if you should get this for your 16-year-old, the answer is probably “No.” But if you’ve got a fully developed prefrontal cortex and you want a fast and powerful ride without breaking the bank, this might be a decent option.

Toyota is finally getting into the game in the world’s largest EV market. On Friday, Toyota officially broke ground on the new Lexus EV plant in Shanghai, its first fully owned manufacturing facility in China and the second in the region, following Tesla.
Toyota is building a new Lexus EV plant in China
After officially announcing it would open a wholly-owned EV plant in China to build new energy vehicles (NEVs) for its luxury Lexus brand in February, Toyota is already kicking off construction.
Toyota finalized a deal with the Shanghai government on April 22 to build the facility. Just over two months later, the company is making swift progress in what’s being called “Lexus speed” locally.
The facility, which spans roughly 1.13 million square meters, could be one of Toyota’s most important to date. Following Tesla, which broke ground on its Shanghai Gigafactory in early 2019, Toyota is the second foreign automaker to construct a wholly owned auto plant in Shanghai.

Construction is expected to be completed in August 2026, with production set to commence in 2027. According to local news outlet The Paper, the facility will be capable of producing up to 100,000 NEVs annually.

Although Toyota will use the new standalone Lexus plant to accelerate EV output, it will also be used to develop vehicles tailored to local buyers.
Since the plant is overseas in Shanghai Bay Area Hi-Tech Zone, Toyota established a “two-line collaboration,” which will enable “24-hour uninterrupted work.”

The first Lexus electric vehicle is scheduled to roll off the assembly line in 2027. Much like for Tesla, local authorities are providing generous support.
For example, the Jinshan District Investment Promotion Office introduced an “order-based” business agreement, addressing Toyota’s “demand list” in advance.
Electrek’s Take
Toyota will use the new Lexus plant as it looks to keep pace with BYD and other domestic EV leaders in China. After launching several new vehicles over the past few months, the Japanese automaker is already starting to gain some traction.
After launching the bZ3X in March, Toyota’s electric SUV was the best-selling foreign EV in China in April, its second month on the market.
Toyota’s electric SUV already outsold the Volkswagen ID.3, ID.4 Crozz, and BMW i3. The bZ3X is Toyota’s most affordable EV, launched in China with a starting price tag of just 109,800 yuan, or about $15,000.
Earlier this month, Toyota launched another electric SUV, the bZ5. The bZ5 is about the size of Tesla’s Model Y, but costs about half as much in China, starting at 129,800 yuan ($18,000).
These electric SUVs are significantly more advanced and feature-rich than the Toyota vehicles we’re accustomed to seeing. They feature advanced smart driving tech, massive touchscreens, and some added bonuses like a built-in refrigerator.
During its EV Tech Day event earlier this month, Toyota’s joint venture, GAC Toyota, announced partnerships with several “car industry bigwigs,” including Huawei, Xiaomi, and Momenta.
Can Toyota keep pace in China with an intensifying EV price war and influx of new low-cost domestic rivals? So far, the new vehicles are helping.
In April, Toyota’s sales in China increased by 20% compared to the same period last year, with 142,754 vehicles sold. Through May, Toyota’s sales are up 7.7% with 530,000 vehicles sold.
Tesla has hired Henry Kuang, the former ‘Head of Autonomy’ at GM’s failed self-driving startup, Cruise.
The automaker has had difficulties with turnover in its Autopilot and self-driving division.

Amidst brand damage in recent years, Tesla has also faced more difficulties securing top hires. A recent leaked recording from a Tesla training session confirmed that the automaker has had a culture problem within its workforce.
However, Electrek has found a rare new executive-level hire in Tesla’s self-driving division.
According to his LinkedIn profile, Henry Kuang has been hired by Tesla as “Director of AI and Deep Learning for Autonomous Driving.”
Kuang was a long-time Facebook engineer who joined Cruise in 2020 to lead the perception team and later became Senior Director in charge of Autonomy:
Cruise was founded in 2013 to develop self-driving technology. It was acquired by GM in 2016. It operated its own self-driving fleet independently of GM, but it also contributed to the development of the automaker’s ADAS system.
A series of accidents and failures in 2023 led the company to withdraw its fleet of over 100 self-driving vehicles from the road.
They have tried to bring back their autonomous ride-hailing service in California, but GM announced that it would stop funding the company in December and commenced a restructuring to entirely discontinue autonomous fleet operations and fold some of Cruise into GM’s ADAS operations for consumer vehicles.
Kuang has reportedly exited Cruise in 2024 and now joined Tesla last month, according to an update on his LInkedIn profile.
