Worlds first enters series production
The world’s first two speed supercharger drive system to enter series production will be demonstrated by Antonov, the automotive technology company, at the Engine Expo exhibition at Stuttgart in Germany next week. The following week, the racing driver Peter Kox will demonstrate the technology at the Zandvoort race circuit in the Netherlands.
And see the results:

Antonov has given on the 16th and 17th may 2006 a demonstration with a Ford Mustang and a Chevrolet 1.8 ltr. Both cars where build with a combined Rotrex/Antonov AMM 2-speed step up supercharger.

What they writes of the demonstration days:
Demonstration of Antonov’s first commercial product: the geared supercharger
Yesterday we had the opportunity to be some of the first to experience Antonov’s two speed supercharger at Holland’s Zandvoort race circuit. A number of vehicles were present and whilst the Ford Mustang was the most thrilling the Chevrolet Lacetti (a rebadged Daewoo) was certainly the most impressive.
The Chevrolet has a 1.8 litre engine (just like my Golf 1.8). However, the torque and power felt
very different, in fact much like that of a 2.3 litre. For example, the car was able to break traction when going into second gear (even with four people in the car!) and we were also able to pull out through corners in third gear (instead of second) due to the large amount of torque at low revolutions.
This ability to provide decent performance with a smaller engine is becoming an increasingly hot topic with auto manufacturers, especially in the wake of high oil prices and tighter emissions controls. In fact, VW have recently announced a diesel engine with makes use of both a supercharger and a turbocharger in order to provide decent performance with a smaller engine at
all engine speeds whilst minimising emissions (such as the smog caused by turbo diesels accelerating at low turbo pressures).
We view the VW system as a highly complex and expensive solution as there have to be complex control mechanisms to decide when best to de-couple (or re-couple) the super charger to provide performance when required whilst preventing the supercharger from over-running and impacting economy.
We believe Antonov’s two speed supercharger provides a far more elegant solution to the problem by offering an upwardly geared supercharger at low engine speeds and a lowly geared supercharger at high engine speeds in one simple unit. This allows the vehicle to give a far higher and smoother power curve as well as a very clean fuel burn throughout the engine cycle, thus
keeping emissions low. We are also reassured from our experience yesterday that the system is not only highly effective but also pleasant to drive; a key element for consumers.
The Ford Mustang, as demonstrated by Le Mans driver Peter Kox
was altogether a different beast; literally. The huge torque from the over 500hp engine made the ride a hairy one and is bound to make a significant impact when it joins the US Hot Rod Power Tour later this year.
The aftermarket Rotrex kit is believed to be receiving a good initial response from the US car tuning market.
We also had the opportunity to experience Antonov’s prototype 6-
speed gearbox demonstrated in a Rover Streetwise. This was the prototype developed in conjunction with Rover Powertrain before Rover’s collapse. Whilst it was noticeable that the shift quality was not as smooth as traditional automatics, these defects will be ironed out in the full production version being developed by Great Wall Motors of China.
Unfortunately the Mercedes CLK was not ready for testing; however, we expect to have it available in the UK for demonstration to investors in the coming weeks.
