We’re used to car races all being about being first and fastest. Today there’s a contest in Lausitz, Germany, where the goal is quite different. The main objective here is to come as far as possible on one tiny litre of petrol. The world record is 5000 kilometers and now the question is: Will someone be able to beat that?
Teams from all over the world participate, many of them made up by researchers and professors. Swedish KTH Royal Institute of Technology sends two teams entirely made up by students and the other day I spoke to Jonas Severin, who has built one of the vehicles, “Sleipner”, together with a group of fellow students.
Sleipner runs on petrol, but being much lighter and having a less powerful motor that turns itself off in downhill slopes where the car can roll down by itself, the energy use is very much below a “normal” car.
The speed isn’t exactly breathtaking, Jonas Severin explains, with an average around 30 km/hour. But if the aim is to get as far as possible on as little energy as possible, going there fast can’t be a high priority. Just can’t get both. And as you see on the photos, Sleipner isn’t really the kind of vehicle you imagine packing your family into.
The other Swedish car in the contest, called Spiros, is more like the cars we are used to and has to be able to work in city traffic and pass a normal vehicle test, having proper lights, working brakes etc.
But are these just fun experiments for students? Jonas Severin says that a developed form of Spiros could maybe be out on the market in 10 to 15 years, able to roll for 500 kilomtres on one litre, instead of a max around 40 kilometers/litre for today’s smartcars.
A while left, apparently. But today is the big test for the KTH teams. Will their vehicles make it in the competition?
- Obviously it isn’t easy for a team of students to beat teams of professors, but it’ll be exiting to see how Sleipner does, says Jonas Severin.
