  • MANAGEMENT: the main task is to manage and coordinate the work of all team members. Every year, the seasonal objectives are established and the team is formed. The experience, gained over many seasons within the team, is the basis for doing this task to the best. Another task is the management of relations with sponsors and suppliers.
  • CHASSIS & SUBSYSTEMS: this group is responsible for designing, manufacturing and assembling the chassis and the other subsystems. The design process is carried out through the use of advanced CAD softwares and Finite Element simulations. The members of this group are also experts in composite materials processing.
  • DRIVETRAIN: this group is responsible for the design of the drivetrain of the vehicle. The main working areas of this group involve the motors, the transmission system and the wheel hubs.
  • STRATEGY & ELECTRONICS: the main task of this group is the development and realization of a reliable and efficient electrical system. Accurate numerical models are developed to simulate the behaviour of the vehicle and optimize the race strategy. Several on-track tests are carried out, in order to acquire data and validate the numerical models.
  • AERODYNAMICS: this group is responsible for defining the external shape of the vehicle body, with the aim of optimizing its aerodynamic efficiency. Fluid dynamic analyses are carried out by means of CFD simulations.
  • COMMUNICATION: the task is to manage the social media and the team website. A communication plan is defined at the beginning of the season. Communication channels are constantly updated to show the team’s route to the Shell Eco Marathon competition.

Our Vehicles

Starting from the second generation of prototypes, the name with which the vehicles are designated refers to deities of Greek mythology. Artemis (Artemide), goddess of the moon, is the daughter of Zeus and Latona (Leto) and twin sister of Apollo.

Leto

This vehicle was born in 2019 and belongs to the Urban Concept battery electric category. The chassis consists of a CFRP structure designed according to lightweight, stiffness, manufacturability and ergonomics criteria. The external shape has been derived from fluid dynamic analyses aimed at maximizing the aerodynamic efficiency.

Daphne

In 2011, the team decided to join the Urban Concept category, giving birth to a new vehicle called Daphne. Its layout is like a standard urban car, with four wheels (steering at the front axle and driving at the rear). The monocoque is made of CFRP, designed to obtain the best aerodynamic performances, recalling a water drop in order to minimize the wind resistance. The vehicle is powered by two 200 W electric DC brushed motors and the power is provided by a Li-ion battery. The tyres are designed on purpose by Michelin in order to obtain low rolling resistance. The vehicle was subjected to many evolutions over the years. The best performance of Daphne was reached at the Shell Eco-marathon 2018, with a consuption of 130 km/kWh.

Apollo

Apollo is the evolution of ARTEMIDE: it was introduced just one year later (2010) and it is a prototype powered by solar energy. The main innovation consists in the adoption of a photovoltaic cell system installed on a wing body at the rear end. The body is the result of in-depth structural and fluid dynamics analysis aimed at maximizing aerodynamic efficiency and stiffness as well as minimizing the mass. It is still the most successful vehicle realised by the team for this competition. In 2010 it won the American competition, distancing the vehicle in second place of about three times. Few months later, Apollo won the European edition and got the lowest consumption ever made in the Shell Eco-marathon competition: 796 km/kWh corresponding to 7070 km/l. In the 2011 edition of Shell Eco-marathon Apollo improved the record and established a new world record of 1108 km/kWh, corresponding to an astonishing 9757 km/l of equivalent consumption of gasoline, the lowest energy consumption ever made by a vehicle in the Shell Eco-marathon competition.

ARTEMIDE

ARTEMIDE was introduced in 2009. It is powered by a hydrogen fuel cell and its design is strongly optimized thanks to the experience gained during the years in Shell Eco-marathon. The chassis consists of a CFRP monocoque, allowing a great mass reduction and a better aerodynamic design. It has two wheels at the front axle and one steering and driving wheel at the rear axis. The name is an acronym of the words:
  • Aerodinamica (Aerodynamics)
  • Resistenza (Resistance)
  • Telaio (Frame)
  • Elettronica (Electronics)
  • Modellazione (Modelling)
  • Idrogeno (Hydrogen)
  • DEsign
In 2009 ARTEMIDE established the Italian record for fuel cell prototypes equal to 2741 km/l and won the Shell Eco Marathon Design Award.

Why not?

Why not? is the first vehicle with which Politecnico di Milano participated to Shell Eco-marathon in 2005. Characterized by a chassis made of aluminium tubes, it was firstly powered by a gasoline engine and then converted to a hydrogen-electric vehicle in 2008. The body is made of carbon fiber and the shape, designed to reduce losses due to air resistance, comes from studies and simulations carried out in the wind tunnel. The front wheels have a lenticular profile and they are made of carbon fiber to obtain high stiffness and allow to minimize weight and fluid dynamic losses. The prototype has a belt transmission system, with a centrifugal clutch. The clutch is directly mounted in the rear wheel rim made of aluminum alloy. This innovative technical solution allowed to win the 2007 "Bosch Technical Innovation Award". In 2008, Why not? scored an equivalent fuel consumption of 1931 km/l, obtaining the Italian record for hydrogen-fuelled prototype.
