The winner is a 4-seater

The winner of the World Solar Challenge 2013 is Stella, a solar-powered car with four seats. The vehicle completed the 3000-km route of the 6-day race across the Australian outback with three people on board.

STELLA WAS DESIGNED BY SOLAR TEAM EINDHOVEN (NL). The team also drove the solar-powered car during the race in Australia. They achieved an average speed of 67 km/h with three people on board. The maximum speed with a full load of four persons is 120 km/h. Already approved for the roads in Europe, the developers expect that mass production can happen within five to ten years as this 4-seater vehicle design is suitable for large scale manufacturing and can be assembled from readily accessible materials and components.

"Stella's performance during the World Solar Challenge 2013 demonstrated the feasibility and appeal of solar-powered cars, and can help the automotive industry define a new category of cars for the near future," said Karsten Penno from NXP Semiconductors, which sponsors this vehicle development. "This milestone victory brings us one step closer to a world in which our vehicles smartly connect to each other and to their environment, addressing the increasing challenges on energy consumption while enabling enhanced mobility concepts."

The so-called “family” car provides four seats, which are rather narrow, and features an engine with enough horsepower to speed-up to a maximum of 120 km/h
In addition to sponsoring Stella, NXP provided car-to-car communications (C2C) technology, which uses the automotive IEEE 802.11p (Wifi) standard to transfer data with the mission control car. This enables the car to optimize car performance and ensure everything is running smoothly based on current road conditions during the race.

The car also uses NXP's LPC1759 micro-controller, which essentially powers the onboard computer, as well as NXP's CAN (Controller Area Network) transceivers, which connect the various electronic devices and sensors. In combination with the C2C technology, this means that the sensors that monitor important information like car speed and engine temperature can be supervised remotely. The used CAN transceiver chips are isolated from the power circuits, in order to avoid short-circuits in case of an accident. The isolated CAN transceivers are also suitable for industrial application, when galvanic isolation is required.
