This is Ducatis VTEC. In using variable valve timing they are able to reduce valve overlap at low speeds to negate positive back pressures pushing exhaust into the chamber and causing a 'flat spot' in the TQ band, while widening the overlap at higher RPMs to allow negative back pressures that suck exhaust gases out creating more torque...

watch the video, then read Kevin Cameron's write up... TECH UPDATE VIDEO: Why Variable Valve Timing?- Ducati's DVT System: After you watch this video, our Tech Editor makes sense of valve overlap and why Ducati has developed its new DVT (Desmo Variable Timing) system.

Any word that the Testastretta DVT will be in the new 959 Panigale?

Great way to get more out of their engines since looking at how you can work better with what you have can go a long way than to bring in entirely new things which can end up costing a lot in the end.
