Move over, e-bikes – there’s a new way to get a power boost for cruising around town, and this one straps right to your legs. The Hypershell X Ultra is a high-tech wearable exoskeleton that delivers up to 1,000 watts of electric assist to your stride, giving “powered walking” the same kind of jolt that e-bikes gave to cycling.

The company behind it, Shanghai-based Hypershell, says the X Ultra is its most advanced performance exoskeleton yet, designed for hikers, runners, climbers, and even skiers who want to go farther and faster without wearing out their legs.

The new model uses a 1,000W “M-One Ultra” motor, around 25% more powerful than before, along with upgraded thermal management and improved energy efficiency. To put that in perspective, the US limits street-legal e-bikes to 750 watts of power, while the EU caps them at just 250 watts. That means this wearable device technically delivers more power to your legs than most legal e-bikes deliver to their wheels.

According to Hypershell, the X Ultra can reduce muscle load on the hips by up to 63%, lower heart rate by as much as 42% while cycling, and even cut oxygen consumption by nearly 40%. The system intelligently adapts to your movement using AI-powered gait mapping and offers 12 activity modes, including new ones for running, snow, and sand, that automatically adjust power delivery depending on terrain and intensity.

Despite all the electronics, it’s surprisingly lightweight. The X Ultra uses titanium alloy and carbon fiber construction to keep the system at just 1.8 kg (4 lb), plus a 410 g (0.9 lb) battery pack. That 72Wh battery claims to deliver up to 65 km (40 miles) of assist when cycling or 30 km (18 miles) when walking, and the system can even regenerate energy on downhills for up to 10% extra range.

With a top speed of 25 km/h (15.5 mph), the $1,999 X Ultra is pricey, but could early adopters help it still kick off a new category of electric mobility where people are the vehicle? Let’s hear your thoughts in the comments section below.

Ferrari has released details about its approach to powertrain sounds with its first electric vehicle, the Elettrica, and I am intrigued. If well-executed, I even think it might convince some petrolheads to give EVs a try.

In short, Ferrari is rejecting fake engine noise for its first EV and opts for an ‘authentic’ yet improved electric powertrain sound directly generated by the electric motors.

Today, Ferrari released the specs and tech details of its first all-electric vehicle, the Elettrica.

I’ve already posted a detailed article going through the specs, as well as the powertrain and chassis technologies developed by Ferrari for this impressive next-gen EV.

But I wanted to write a separate article specifically about Ferrari’s approach to sound in its first all-electric car because I think its strategy is exciting. I even believe that it could convince some hardcore petrol heads who reject EVs to give them a real shot.

For years, legacy automakers have struggled with how to engineer an auditory experience for EVs that replaces the roar of combustion.

Whether you like them or not, engine sounds are essential, especially in performance vehicles. They are part of the identity of certain cars – a sort of signature. They can be emotional. They can give a sense of power.

But beyond that, they are information. The pitch, volume, and texture of the engine sound provide critical, real-time feedback to the driver about RPM, load, and the car’s health.

Some electric automakers are using curated soundscapes (like BMW with Hans Zimmer) or trying to mimic V8s (like Dodge with its “Fratzonic Chambered Exhaust“). I don’t have a problem with those as long as they are optional, meaning you can turn them off, as I’m not a fan of cars making fake noises.

Other automakers are simply letting the natural sounds of the electric motors exist. There’s nothing wrong with that. However, considering that electric motors produce minimal sounds, which are then trapped inside a metal casing, you rarely hear anything significant, especially in modern vehicles with quiet cabins and even active noise cancellation.

For most EVs, this is not a problem, but for a performance electric vehicle, it does feel like something is missing.

Ferrari’s approach to sound in its first electric car

Ferrari’s solution is a novel one, focusing on what it calls an “authentic voice unique to the electric engine.”

I attended Ferrari’s tech day for the Elettrica, and Antonio Palermo, the brand’s head of NVH (noise, vibration, harshness) and sound quality, gave an excellent presentation about how the company approaches the problem.

He said that there was a lot of internal debate at Ferrari about how to manage the powertrain:

It took us a long time to reach a consensus about what sound to get, but it was clear that we wanted something authentic.

Again, the problem with being authentic with an electric vehicle is that if the powertrain and packaging team did their job right, there’s little sound to play with.

An electric guitar inspired Palermo’s solution. Unlike an accoutic guitar, an electric drive unit doesn’t a hollow body or sound hole to convert the string vibrations into audible sound.

Much like an electric guitar, Ferrari’s solution involves capturing and amplifying the actual vibrations of the drivetrain components. The automaker explained:

A high-precision sensor installed on the rear axle picks up the frequencies of the powertrain, which are amplified and projected into the surroundings as with an electric guitar… the sensor used is an accelerometer installed at a very rigid point on the inverter casting.

This approach, which utilizes an accelerometer to capture solid-borne vibrations from the drive unit, enables Ferrari to amplify a sound that matches exactly what the motors produce – making it authentic.

Ferrari insists the sound will only be used when “functionally useful” to provide feedback to the driver and will be directly tied to torque requests.

In normal driving situations, silence is preferred to maximise acoustic comfort, but when the driver requests torque from the powertrain by accelerating or uses the shift paddles in manual mode, the sound activates to offer dialogue and connection between driver and car.

Palermo added that the latency is non-perceivable to the human ear. In spirited driving, you will be able to hear the motor accelerate, regen, or even decouple since front motors of the Elettrica are equipped with a disconnect to turn the vehicle into a rear-wheel-drive.

The entire system was reportedly developed in-house, giving Ferrari complete control over the vehicle’s final acoustic signature.

Electrek’s Take

This is a fascinating and, frankly, refreshing move from Ferrari. We’ve seen numerous gimmicks from legacy automakers attempting to make their EVs feel and sound like the gas cars they are replacing. Most of them fall flat because they are fundamentally inauthentic.

Ferrari’s “electric guitar” approach is different. By choosing to amplify the real sounds of the electric motor and inverter based on the real vibrations, they are embracing the new technology rather than hiding it. They are making a confident statement that an electric powertrain can be emotionally engaging on its own terms, without having to pretend to be something it’s not.

It’s a brilliant piece of engineering that stays true to the brand’s performance-focused ethos, where sensory feedback is a critical part of the driving experience. And it’s optional. If you prefer a completely silent drive, you can disable it.

The purists who were worried that Ferrari would lose its soul in the EV transition should be encouraged by this.

Ultimately, it could even convert some of those petrol head purists who can’t stand a car experience without the smell of gasoline and the roaring sounds of combustion.

However, we need to hear it first. Everyone who heard it at Ferrari seemed impressed, but they are obviously biased. The test drivers are reportedly enjoying the audio feedback, but the brand is staying secretive.

As I reported in my full article about the Ferrari Elettrica, the automaker is doing the unveiling in three parts. This is just the first part, covering specs and technical details. We will have to wait for the second (Q1 2026) or third (Q2 2026) part to hear about the vehicle.
