Saietta’s motor takes lightweight EVs 10% further


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, which were led and overseen by independent and highly respected Dutch engineering consultancy New Electric, saw two Renault Twizy demonstrator vehicles go head-to-head in comparison assessments on public roads in Amsterdam, Netherlands.

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, on varying road surfaces. The engineering team at New Electric concluded that the Saietta AFT 140 Twizy had on average at least a 10% increased efficiency gain over the standard Renault Twizy.

The findings open the way to tremendous 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 requirements.

The Saietta AFT 140 Twizy and standard Renault Twizy model were assessed across multiple drive cycle tests in Amsterdam, ensuring a comprehensive test program was completed.

In addition to increasing efficiency by 10% and therefore real-world driving range, the New Electric team also concluded that Saietta’s AFT 140 motor performs exceptionally well during low speeds and stop/start conditions, making the technology ideal for inner-city mobility.
