SZEmission

Mass: 95 kg

Hatékonyság: 291 km/kWh

Shell Eco-marathonon elért eredmények:
2023 – Nogaro – 1. hely
2023 – Nogaro (önvezetés) – 1. hely
2022 – Assen – 1st place
2022 – Nogaro (self-driving) – 2nd place
2019 – London – 6th place

Legújabb versenyautónk, a SZEmission 2019-ben készült el, azóta folyamatosan fejlesztjük. A 2022-es szezonban energiahatékonysági világrekordot értünk el a SZEmission-nel az Assen-ben megrendezett Shell Eco-marathon-on. Versenyautónk 284 km volt képes megtenni 1 kWh energiából. A 2023-as versenyen ezt a rekordot tovább javítottuk, így értük el a 291 km/kWh-ás hatékonyságot. A módosított csepp formájának köszönhetően 0,1365-es légellenállási együtthatóval rendelkezik, amely egy átlagos személyautó 0,3-as értékéhez képest jelentősen kisebb. A légellenállás mellett a tömegcsökkentésre is nagy hangsúlyt fektetünk. A jármű önhordó karbon-kompozit karosszériával rendelkezik, így jelenlegi menetkész tömege 95 kg. A SZEmission-ben LiPo 350 – 530 Wh-ás akkumulátorokat használunk, meghajtását pedig egy PMS motor biztosítja fogasszíj hajtás segítségével.

SZElectricity

Mass: 90 kg

Efficiency: 195 km/kWh

Shell Eco-marathon versenyen elért eredmények:
2018 – London – 6th place
2017 – London – 4th place
2016 – London – 3rd place
2015 – Rotterdam – 3rd place
2014 – Rotterdam – 4th place
2013 – Rotterdam – 7th place

As the predecessor of SZEmission, SZElectricity served as the team's racing car at the Shell Eco-marathon between 2013-2018. When it was built, the weight of the vehicle was 90 kg. The frame of the car was made of aluminum, then a carbon body was added. Even in this period, the drive was carried out by a PMS motor (250W). SZElectricity had a 0,65 m² solar panel on top of the body. In addition to monocrystalline solar cells, 48 V Li-ion batteries provided the car's energy. For the 2015 race, the vehicle underwent major improvements, thanks to which a new nose cone, lightened front suspension and LIN over DC communication were added to the race car. In 2016, our team dreamed even bigger, as they installed an optimized axle stand, a 3D printed rack and pinion steering system, and a self-developed PMS engine with external rotors in the vehicle. In addition, we also developed a new power supply, automatic start and cycle control during the season. The most significant development for the 2017 and 2018 seasons was optimization and mass reduction. By reworking the brake system, the reliability of the vehicle has improved significantly, and the spring suspension has also been redesigned. Our last development was the design of the clutch drive.

SZEvolution

Mass: 138 kg

Shell Eco-marathon versenyen elért eredmények:

2012 – Rotterdam – 2nd place
2011 – Lausitz – special award
2010 – Lausitz – 1st place

Between 2010 and 2012, our team's alternative drive vehicle was SZEvolution. It had a total weight of 138 kg at the time of its construction. Similar to SZElectricity, this concept car was composed of an aluminum frame and carbon body, which was powered by two 1kW BLDC motors. Monocrystalline solar cells with an efficiency of 18.5% were placed on 7 square meters of the vehicle's surface, however, in the case of SZEvolution, the energy source was also supplemented with one 48V Li-ion battery. Our SZEvolution vehicle is the first Urban Concept car of the Shell Eco-marathon that ended the race with a positive energy balance, which means that it ended the race with more energy than it started with.

SZEnergy Car

Mass: 152 kg

Shell Eco-marathon versenyen elért eredmények:

2009 – Lausitz – 1st place

The SZEnergy Car was finished by 2008 and competed with our team until 2010. At the time of construction, the vehicle weighed 152 kg and was also composed of an aluminum frame and carbon body. One 2 kW BLDC motor was responsible for the drive, for which energy was provided by 7 square meters of 17.5% efficient monocrystalline solar cells and one 48V Li-ion battery. The SZEnergy Car was our first racing car, which achieved the best energy balance in the field.
