As if on the run, the racing machine shoots up the snow-covered pass road. And leaves a cloud of ice crystals and snow behind it. No wonder: the sheer unbridled power pushes rally driver Matthias Ekström into the seats. The yaw moment craves curves. And if there are no bends, the “Audi S1 Hoonitron” just drifts off the line. Ekström: “The power you feel from the first moment is insane. Together with the Quattro drive and the hydraulic handbrake on the rear axle, you can get through even the tightest hairpin bends effortlessly.” What's unique about the Hoonitron is that at the push of a button, it goes forward just as fast as it goes backwards. The noise level is also unique. Apart from a loud whirring sound like that of an oversized hoover, nothing can be heard.
However, the Hoonitron is not comfortable. For the sake of performance, no frills were added. At least there is a windscreen wiper. But that's about it. The seating position is unusual for motor sports laymen. This is partly due to the positioning of the battery, which in turn ensures an extremely low centre of gravity. Audi does not allow itself to look too deeply into the technical cards. This much can be revealed: two electric motors, 800 volts of voltage, all-wheel drive, power in abundance, a chassis made of carbon fibre and the full safety standard of the supreme motorsport authority FIA – these are the key data of the vehicle.
It is also known that the electric power distribution between the front and rear axles is fully variable. And that the electric motors reach maximum speeds of 28'000 rpm, which is why a gear ratio of about 12:1 was defined for the drifts. If you can do the math, you will come to the conclusion that around 3000 Nm of torque are at work per axle. These extreme forces in combination with the short overhangs make spectacular drifts possible. And this at a wheel speed of more than 200 km/h. Even Michael Knight from the cult series “Knight Rider” would have been jealous, despite the activated “Super pursuit mode”.
This one-of-a-kind racing machine was actually supposed to be driven by Ken Block. The news of his sudden accidental death in January 2023 stunned the motorsport world. The US American was the uncrowned king of the transverse cars. He was considered one of the best rally drivers in the world. With the “Audi S1 e-tron quattro Hoonitron” prototype developed especially for him, his dream came true. Together with Audi, Ken Block wanted to show that you can also have extreme driving fun and deliver top performance with a purely electric drive. This vision has now been revived under the motto “Racing for Ken Block” on the Flüela Pass in Davos, as the new video shows.
