In real-world tests Saietta’s motor takes lightweight electric vehicles (EVs) 10 percent further

Smaller urban vehicles could benefit from more efficient motors to increase range

Real-world efficiency testing of Saietta Group’s ground-breaking AFT 140 electric motor has shown that the technology can dramatically improve the driving range of lightweight electric vehicles (EVs).

The tests were led and overseen by independent and highly respected Dutch engineering consultancy New Electric. They put two Renault Twizy demonstrator vehicles head-to-head in comparison assessments on public roads in Amsterdam, Holland.

The first Twizy was a standard Renault model while the second was upgraded to Saietta’s AFT 140 electric motor. All other systems and components were left untouched meaning that the only difference between the Twizy siblings was the original motor in one test vehicle and the AFT 140 motor in the other EV.

The testing took place across two days in a wide range of weather, temperature and traffic conditions, with varying road surfaces. The engineering team at New Electric found that the Saietta AFT 140 Twizy had on average at least a 10 percent increased efficiency gain over the standard Renault Twizy.

The findings open the way to a wide range of opportunities in electrifying a broad range of two, three and four-wheel lightweight vehicles, with an advanced drivetrain that is cost-effective, offers optimal power and has an enhanced real-world driving range.

The ramifications of this will see the likes of motorbikes, mopeds and quadricycles such as the Twizy, used primarily in town and city centres across the world, become zero-emission vehicles that meet all legislative and customer requirements. This is great news, especially with more city centres introducing zero emission zones, and in the future, it could be that smaller electric vehicles become the norm.

Wicher Kist, at Saietta Group CEO, said: “We are absolutely delighted that these independent tests have shown the technical capabilities of our AFT 140 electric motor, proving the significant improvement the technology can make to applications in the real world today.

“Internally we always knew how transformational our axial flux technology is, but for it to be validated by a respected and neutral engineering powerhouse like New Electric is proof to the wider industry that Saietta Group is leading the way in this mobility field. To boost a battery electric vehicle driving range by 10 percent through simply swapping the electric motor is highly impressive.”
