  • Saietta’s new motor technology contribute to more agility and efficiency

    2021 Saietta AFT 140Some real-world efficiency testings of the Saietta Group’s advanced AFT 140 electric motor have demonstrated that the technology can dramatically improve the driving range of lightweight electric vehicles.

    The tests included two Renault Twizy demonstration vehicles that were put in a head-to-head comparison experiment on public roads in Amsterdam, Netherlands.

    The first vehicle was a standard and stock Renault model, and the second one was geared with Saietta AFT 140. Everything else was left original and didn’t undergo any aftermarket upgrades or changes.

    All tests took place across two days in different road settings, and with different weather, temperature, and traffic conditions. The examination team concluded that the Saietta AFT 140 Twizy showed about 10 percent increased efficiency over the standard Renaut Twizy.

    Also, the conclusions point at the great opportunities that the electrified technologies offer for the two-, three-, and four-wheel lightweight vehicles and the flexibility they offer in terms of other drivetrain technologies.

    The AFT 140 is the first liquid-cooled axial flux motor from Saietta that will go into mass production. The unique design ensures some class-leading performance and high torque density at low voltage and efficient urban duty tasks. The motor itself is compact and lightweight and is specially designed to retain a class-leading performance-to-efficiency ratio. The AFT 140 motor in the Twizy vehicle is an in-wheel variant of the AFT technological concept and showcases the full flexibility and modularity of Saietta’s motor tech advancements.

  • World’s First 3D-Printed Car is Here! [VIDEO]

    It will be the end of the automotive world as we know it, when the world’s first 3D-printed car drives out of McCormick Place in Chicago. During the six day event of International Manufacturing Technology Show, the vehicle will be printed over 44 hours then rapidly assembled by a team led by Local Motors. Then there will be a historic first drive set that will take place in the morning of September 13th.

    The car carries the name “Strati” and it will be 3D printed in one piece with the utilization of direct digital manufacturing (DDM). And this is definitely history, because for the first time this method has been used to make a car.

    And if you wonder how the mechanical components such as battery, motor, wiring, and suspension will be printed, well – they won’t. They will be sourced from various suppliers, including Renault’s electric Twizy.

    The hopes for the Strati are to change the manufacturing status quo as well as consumer’s experience. It is also an example for the development of technology nowadays and how a car can be born in an entirely different way.

    The innovative vehicle uses the material science and advanced manufacturing techniques pioneered at the U.S. Department of Energy’s (DOE) Manufacturing Demonstration Facility at Oak Ridge National Laboratory (ORNL). The 3D printing will also contribute to faster and innovative manufacturing solutions.

    The machine behind this project is called BAAM, which stands for Big Area Additive Manufacturing machine. Its deposition rate of 40 pounds per hour of carbon reinforced ABS plastic and its large size allow for 3D printing of larger parts.

    Strati will be displayed at AMT’s Emerging Technology Center. Local Motors, is a platform, which empowers anyone to design, build, and sell machines. It combines global co-creation and local micro-manufacturing to bring hardware innovations faster to the market. The Company is created by community of enthusiasts, hobbyist innovators and professionals which have gathered together to solve complex mechanical problems. Currently, Local Motors have plans to launch production-level 3D-printed vehicles for purchase from the general public. This will probably happen several months after the show.

  • Renault Twizy ZE – £6 690

    Renault will actually hit the market with the Twizy, which will be on display at the Barcelona Motor Show. The manufacturer will exhibit two versions powered by a 17HP motor: Urban and Technic. The price of Twizy will be £6 690 ORT.

    The Technic trim level costs £7 400 and monthly battery lease cost for both versions will be £40 including VAT for a 36 month/4 800 miles per year agreement.

    Customers can now pre-reserve their Twizy online at renault-ze.com and this requires a £20 deposit via a secure online payment module. The website is available in 38 countries and has already received more than five million visits, a figure which provides a dramatic illustration of the interest motorists are showing in the Renault Z.E. programme.

    Renault Twizy ZE

    Twizy makes city motoring easier and safe:

    • Twizy gets around town faster than a traditional city car thanks to its unprecedented ultra-compact dimensions which also allows easy parking
    • It offers two occupants – sitting in tandem, one behind the other – greater safety compared with a two-wheeled vehicle, thanks to an extensive list of active and passive safety features

    Twizy makes getting round town more enjoyable

    • It is more agile than a car, whilst its acceleration performance is comparable with that of a scooter
    • Twizy’s electric motor accelerates smoothly and silently, while torque is immediately available
    • Its wraparound bodywork and side deflectors ensure enjoyable open-air motoring, protected from the elements

    Accessories for the Twizy lifestyle

    • An all-purpose bag with a capacity of 50 litres
    • Additional protection against the weather
    • A Parrot audio kit including Bluetooth connectivity, plus a USB connector, a jack socket and an Apple connector
