New micro-car concept puts aluminium in the middle of mobility for future cities

A joint study that Hydro has carried out with Forschungsgesellschaft Kraftfahrwesen mbH in Aachen (fka) and School of Design Pforzheim, related to aluminium use in urban vehicle concepts, clearly demonstrates aluminium’s strong position in vehicles of the future. The study was presented just last month at Aachen Body Engineering Days 2018. Hydro participated with engineering expertise from three of its business areas: Extruded Solutions, Primary Metal and Rolled Products. Mr Pascal Wagner, head of global products for Hydro’s Rolled Products business area said that “This is a great example on how our customers and society can profit from Hydro being a completely integrated company with expertise along the whole value chain. This project has given us the ability to promote our broad product range to an important audience. Extrusion alloys, sheet grades and ‘green’ metals are all well appreciated.”

This past May, the United Nations’ Department of Economic and Social Affairs released a report stating that 68 percent of the world population would be living in urban areas by 2050. Further, the UN reported that sustainable urbanization would be key to sustainable development.

With the macro-economic cost of traffic jams in Europe having tripled between 2006 and 2011, in addition to greater space limitations and carbon dioxide emissions in cities, conventional cars are being pushed out of cities. New vehicle and mobility concepts are moving in.

Focused on the L7e micro-car class, the new study by Hydro and fka demonstrates how cars for urban driving can be constructed largely in aluminium. It shows how aluminium can enable cars to achieve the L7e classification and still reach the safety levels typically provided by larger cars.

Light and agile cars in aluminium
The L7e vehicle class describes a small and light, battery-driven micro-car. The requirements for such cars are:

Under 3.7 meters in length, 1.5 meters wide, and 2.5 meters high
Lighter than 450 kilograms (excluding the battery system)
Maximum continuous rated power 15 kW
Maximum speed of 90 kilometers per hour
A closed body with no fewer than three opening sides
Maximum of four non-straddle seats with safety belts

Cars within the L7e class, however, normally do not offer the same passive safety system for passengers as larger models. Consequently, customers have found such vehicles unattractive.

Raising the level of passive safety was one of the targets of the L7e project. Nunzio Cuppoletta, who is responsible for the automotive market sector for Hydro’s Extrusion Europe business unit said that “We tested the passive safety performance of our concept L7e micro-car according to Euro NCAP crash test methods and the vehicle passed every test for normal M1-class cars.”
