Lightyear One sets new record for most aerodynamic production car

Helmond, October 28th, 2019 – Lightyear validates the unprecedented design performance of the spacious 5-seater EV Lightyear One with an impressive low energy consumption. According to Lightyear, this achievement is only possible by starting the design of the car from scratch with a completely new architecture. The company is committed to its vision of making EV mobility scalable through the grid-independent solar car, and therefore, to keep on delivering optimal performance that matters most for EV drivers.

In only 2,5 year, the innovative Dutch tech company built its first prototype: Lightyear One, based on its legacy as four-time ‘World Solar Challenge’ Champions. With only months since the prototype’s unveiling, the company has been fully dedicated to the validation of the optimal design performance of Lightyear One; and keeping its energy consumption at lowest is of paramount importance. Lightyear owes its world championship title to the ability of predicting the car’s energy consumption extremely accurate.

World record

Recently, Lightyear’s engineering team has performed the first series of validation for the aerodynamic performance of Lightyear One. During a week of testing in a windtunnel facility in Turin, the Lightyear team was able to validate their simulation models and confirm a drag coefficient (Cd) below 0.20. This means a newly established record in aerodynamics for Lightyear One. The exact number will be made public when the car is fully developed. With the results as they stand, Lightyear One will likely be the most aerodynamic car when available in the market.

Unprecedented design performance

With these tests, Lightyear is thrilled to see their calculations validated and excited to reach unprecedented design performance. Optimal aerodynamics are a key factor to achieve an outstanding low energy-consumption for a vehicle that combines the passenger capacity of a 5-seater and the trunk capacity of an SUV. To achieve the most optimal aerodynamics within these requirements Lightyear started designing from scratch with an innovative mindset, not attached to existing conventions. Lightyear’s CEO, Lex Hoefsloot, says: “This significant improvement is only possible because we re-designed the car as we know it, radically starting from scratch and focussing on EV performance metrics that matter most for EV drivers: ample range and fast-charging speeds”.

Lightyear: the future of EV is grid-independent

Lightyear’s vision is radical too; the company is committed to making electric driving accessible on a large scale; with a grid-independent car, a solar car. For Lightyear, grid-independent means convention-independent. Through its commitment, Lightyear clearly chooses for a strategy that differentiates itself from the current EV manufacturers, that focus on conventional metrics such as acceleration and achieve it through larger battery packs.

The windtunnel testing of Lightyear One is made possible through funding received from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 848620. This funding is part of the development of Lightyear One.

About Lightyear

Lightyear is on a mission to make clean mobility available to everyone, everywhere. Lightyear aims to eliminate the two biggest concerns for electric cars - charging and range - with an energy-efficient design and integrated solar cells. This allows motorists, depending on the climate, to drive up to twenty thousand kilometers per year on the power of the sun. The fast-growing company was founded in 2016 and currently employs more than two hundred employees. The team is made up of a mix of young talent and experienced names from the automotive industry, including former employees of Tesla, Jaguar, Landrover, Audi, McLaren, and Ferrari. In 2019, Lightyear received the Horizon 2020 grant from the European Commission, under grant agreement number 848620. In the summer of 2019, Lightyear launched its first driving prototype, Lightyear One, and opened a new office in the region of Brainport Eindhoven. The prestigious TIME Magazine acknowledged Lightyear One as one of the ‘100 best inventions’ of 2019. In 2020, Lightyear won the ‘Rising Star’ and ‘Most Disruptive Innovator’ Award of the Technology Fast 50 program organized by Deloitte. The first model of Lightyear One will go into production in the summer of 2022 as an exclusive car series.
