Mahle has commissioned a new test bench for electric drives at its facility in Stuttgart, Germany, which it will use to develop and test e-axles and e-drive units. According to the company, the first test on a unit has been successfully performed on behalf of a customer.
“With the commissioning of the test bench, Mahle continues the targeted expansion of its global range of services for e-mobility,” said Dr Martin Berger, vice president, Corporate Research and Advanced Engineering, Mahle. “Both our customers and our developers can now benefit from an ultra-modern facility, which is one of only very few in Germany.”
Mahle says in future, the new e-test bench will be used on behalf of international customers to carry out functional development work, simulate highly dynamic, transient modes of operation, perform efficiency measurements and torque vectoring, and simulate wheel slip scenarios.
Maine-based yacht builder Hodgdon is to produce two all-electric versions of its Venetian line of electric tenders. The US company has worked on the project in conjunction with Vita Yachts, which, in addition to building vessels itself, has developed a range of electric propulsion systems.
“At Hodgdon we have always endeavored to push the boundaries in terms of materials, technology and design to optimize performance. Our move into providing all-electric tenders is further evidence of this and addresses increasing demand from the market for zero-emissions tenders onboard superyachts,” noted Audrey Hodgdon, director of sales and marketing. “We’re pleased to have developed two tenders that offer benefits that can only be achieved with electric, while remaining true to the Venetian line’s style and quality.”
Hodgdon’s tenders will use Vita’s V3 and V4 drive configurations, which have an output of 220kW and 440kW respectively.
Torqueedo has recently unveiled a raft of new electric marine propulsion products for 2021, in an expansion of many of its ranges.
First up are two new saildrive options, the Deep Blue 50 SD and Deep Blue 100 SD, which the company says are the result of a cooperation with supplier ZF. The fixed saildrives will be available in 50kW and 100kW outputs, and are designed for sailing speeds up to 30kts while also providing efficient hydrogeneration, keeping the system’s high-capacity batteries charged while under sail. Torqueedo notes that in common with its existing Deep Blue and Deep Blue Hybrid systems, energy from solar panels, wind or hydrogeneration can be integrated into the central system, along with a range extender for seamless backup power.
French shipyard Piriou has announced it is one of three winners of a call for notification of interest from the Offshore Wind Innovation Challenge – managed by WPD and the Brittany Maritime Cluster – Pôle Mer Bretagne Atlantique – thanks to its Crew Transfer Vessel (CTV) with hydrogen hybrid propulsion. WPD is a Germany-based specialist in offshore wind-energy generation; the Brittany Maritime Cluster is an innovation cluster tasked with developing technologies for emerging marine markets.
Following a call for proposals launched at the end of 2019, Piriou drew on its experience in crew transfer to oil fields, having delivered more than 100 18-55m crew boats and 10 27m and 22m CTVs for wind farms, broadening its range with an H2 low-emission CTV design.
Marine electrification specialist ABB has secured a US$150m order to equip five new-build cruise vessels from Fincantieri with its Azipod electric propulsion system.
The company says that each cruise ship will be powered by twin Azipod units, with part of the order including the largest and most powerful Azipod propulsion units ever to be installed at Fincantieri, rating at 20MW each. The vessels will enter service between 2023 and 2026.
“We look forward to collaborating with Fincantieri on these world-class vessels, setting them on course for eco-conscious cruising. Today’s passengers expect sustainable journeys, and we are honored to support Fincantieri’s environmental goals with our technology that stands for innovation and efficiency like no other,” commented Juha Koskela, division president, ABB Marine & Ports.
Electric marine specialist Torqeedo is to hold a digital conference on November 19 at 2:00pm CET. The event will see the company’s leadership discuss a variety of trends shaping the future of clean cities, public transportation and the overall commercial and recreational marine markets along with an outline of how Torqeedo plans to address them in its current and future product developments.

A project to build a luxury day-boat powered by lithium sulfur cells is underway, courtesy of an agreement between Yachts de Luxe (YdL) of Singapore and Oxis Energy, a company working on the commercialization of Li-S battery cells. The vessel is to be called Galaxy of Happiness and will be designed by Jean-Jacques Coste of Fraser Yachts
Oxis says it will work with YdL to design the new 40ft (12m) luxury day boat, which will carry a 400kWh battery. The design, manufacture and installation of the cell modules and BMS will be carried out by UK-based Williams Advanced Engineering, a subcontractor on the project.
Spirit Yachts says it has successfully delivered its new Spirit 44CR(e) to her Canadian owner. Based on the Spirit cruiser racer (CR) design, the company notes its 44CR(e) was commissioned for an eco-conscious customer who set the company a goal of “near total energy self-sufficiency”. The ‘e’ denotes the yacht’s electric drive system.
The 44ft (13.4m) sloop-rigged sailing yacht has a lightweight (65kg) Oceanvolt ServoProp15 sail drive, which is powered by 48V DC batteries (total capacity 30.4kWh, made up of 16 x 1.9kWh batteries). The electric drive system uses hydro generation via the electronically controlled pitch propeller to regenerate the batteries while sailing.
