– If we go down to 90 kg, we will win, said Sivert Hatletveit earlier this year. He leads the NTNU gang that built the DNV GL Fuel Fighter this year, the Norwegian participant in the Shell Eco Marathon – the race where you should ideally produce energy while driving beyond to win.
I was in Trondheim impressed by self-built carbon wheels (weight of 2.5 to 1.5 kg each) and a self-produced rig where we measured rolling resistance and a chart which could also integrate into an art museum.
I do not know what happened. Maybe they did not reach their 90 kg, or maybe the winner had even found some benefits – they were at least number two. Very honorable – almost 150 teams participated.
However, a problem was obvious. The track, which is located in the Olympic Park of London, was this year the map of 1.6 km at only 970 meters.
– What caused the most problems for our car was the turn, according to Håvard Vestad. – One of the 30 in the team this year
– At first try we had some problems with the suspension, as well as the tires and the spring in the most sweet team. After we repaired this and took some steps to optimize the engine controls, it just got better and better. "
Increasingly, he can safely say, the teams had four attempts together, and the DNV GL Fuel Fighter got better results for every attempt.
started using 1 kWh in 105 kilometers, but the end result was incredible: 176 km / kWh, there was only 6-7% of the winner's result
Not that they could be compared, but to give you an idea: a Nissan Leaf makes about 15 km on 1 kWh
If the winner had gone on like last year, NTNU had become the best team.Last year , the INSA Toulouse car was powered by an internal combustion engine.Then they won this category, they traveled the equivalent of 685 kilometers with a liter of gasoline!
But this year, they replaced the gasoline engine with a 250 kW electric motor and an advanced engine control program. And just like last year, they had two Norwegian students in the team. The Sandnes Torkel Genet was the leader of the year team and Simen Sandtorv Hansen of Bergen was the leader
Simen gives us a good track to find out why they won and not Trondheim.
– The car weighed as much as the driver With equipment, he revealed and could say that the weight needle had stopped at 67 kg. In other words, a few extra pounds must be removed before the competition next year.
This is Eirik Evjan Furuholmen of Oslo fully conscious. He led the team's R & D group this year and will be the project manager for the car next year.
– Next year the rules have changed again, for example, cars in this category will have two doors. This means that we need to develop a new, simpler chassis. A demanding job, but we look forward to it, he says.
He further states that in addition to further developing the electric concept car, the team will also start a project to develop a self-driving car.
– We will also use the data logger that we have today to create a digital twin of the car. We will use it for Live for optimization. In addition, we will make our electrical systems even more reliable – and so the big task will be: a new chassis.
In other words: Quite turned to the future.
to see the car next year. The first sketches that we have shown a few months ago sometimes looked very good
It's not easy to do something original in the frame Regulatory, but it looks like the car of 2019 will also be a candidate The price of design
Which reminds me: there are a number of other awards to be awarded as part of this event. But it will not happen until tonight's party, long after it's written.
