Our CarTuner was originally developed for the energy system of the vehicle: there it creates a harmonious vibrational field in which artificial frequencies no longer produce resonance.
Many of our customers have told us that they no longer perceive electrosmog in the vehicle as a burden and that they also use less fuel. We noticed this in our own vehicles too and decided to investigate the phenomenon more closely. We planned the “Swiss Harmony CarTuner Test”, a two-fold journey from London to Edinburgh and back, to find out how great the savings really are.
We rented a car for the purpose. The first outward and return journey was entirely without the CarTuner, just as we had received the vehicle from the car rental company. Only for the second tour, which took place the very next day, did we fit the CarTuner.
We took meticulous care that the second journey followed the same route at speeds kept as close as possible to the first.
We also invited Jonathan and Matthew from J Motion, a professional video production company in England, to accompany us on the journey in order to document and film it.
You can see the result in the video below. The summary of the data can be found further down on this page.

The results of the Swiss Harmony CarTuner test in detail:
On the first outward journey to Edinburgh we drove 653 km and consumed 34.77 litres of diesel. That corresponds to a consumption of 5.3 l/100 km.
On the way back to London it was 661 km and we filled up with 39.67 litres. That corresponds to exactly 6 l/100 km.
The second tour to Edinburgh with the CarTuner fitted gave a consumption of 4.1 l/100 km. That corresponds to a saving of 22 %.
On the way back to London with the CarTuner fitted we consumed 33.66 litres, that is 5.1 l/100 km. The saving was 15 %.
Here you can see the data at a glance:
| Without CarTuner | With CarTuner | Saving in % | |
| From London to Edinburgh (406 miles) | 5.3 l/100 km | 4.1 l/100 km | 22 % |
| From Edinburgh to London (414 miles) | 6.0 l/100 km | 5.1 l/100 km | 15 % |
One route was driven with one vehicle, once without and once with the CarTuner; that is a single case, from which no general statement follows. The journey concerns consumption, not health.
