Welcome to Part II of our series on what the future holds for transmissions and just what technologies are on the rise and expected to overthrow the current might of the dual-clutch transmission. On the agenda today is a company by the name of Zeroshift, which is another British gearbox manufacturer who have been developing their seamless shifting transmission since 2002. They have come up with a recipe which they believe will eventually funnel down to millions of production cars.

If you thought Xtrac’s Instantaneous Gearshift System was hard to understand, then get a load full of how Zeroshift’s breakthrough transmission operates. The Zeroshift system replaces the standard synchromesh system with a pair of interlocking rings which overlap one another and are then mounted onto a dog ring. These two rings transfer torque in opposite directions resulting in the left-hand ring driving the gear to the right and the right-hand ring driving the gear to left.

Under hard acceleration, both rings are pulled to the side of first gear and just before the car hits maximum revs, one of the rings shifts over to the right in preparation of 2nd gear being selected. All said and done, the Zeroshift system can literally shift gears in zero seconds resulting in breathtaking acceleration capabilities.

In fact, Zeroshift’s managing director Bill Martin is so proud of this system that he is sure that if the Zeroshift system arrived first, dual-clutch transmissions would never have been invented.

As of yet no production cars are using this system, however the Joss JP1, Australia’s first ever supercar, will be using Zeroshift’s seamless gear change technology when it hits the production line in a few years. In fact, this system is so effective that the Joss JP1 is capable of hitting 62 mph in less than 3.0 seconds and 100 mph in an incredible 6.0 seconds.

What’s more amazing about these performance times is that the JP1 is only expected to be fitted with a 6.6-liter V-8 engine producing around 500 horsepower, yet it can achieve similar performance times to that of the Lamborghini Aventador LP700-4 and Pagani Huayra, both of which have significantly more powerful engines.

Oh yeah, and we forgot to mention that a top speed of 224 mph is also expected. Not bad for something coming from the ‘Land Down Under.’

Unfortunately, the Zeroshift seamless gear-change system is unlikely to hit mass production for a few more years, but it is clear that the double-clutch gearbox is coming to the end of its relatively short life.

Maybe it’s best if we stick with what we can only have for now.

We hope so, because we think, it’s fewer hassles with the new gearbox technology.

With this, it’s really not impossible for the dual-clutch transmission to be replaced. If it has been done, then it’s more likely that it will happen again.

I’ll wait for that Australian car then. Hopefully, it will create a way for automotive to use this new gearbox technology more.
