In motor racing the principle of sequential gear shifting has been established a long time ago to reduce not only gear shift duration but also driver stress.
An over-revved engine needing expensive repair or a race coming to a grinding halt alongside a guide rail, because while accelerating at the exit of a fast corner at the gripping limit the intended upshift to fifth turned out to be a downshift into third due to a missed slot, can thus be reliably prevented.
Looking at the history of motorcycle engineering for comparison it shows that at the beginning manual gear change mechanisms have been used featuring the H-pattern as well. The growing engine power and vehicle velocity, however, rendered this kind of operation soon impossible and led to the foot operated gear shift mechanism in place until today. Since the foot is not suited to two-dimensional control movements the sequential gear shift principle was able to fully establish itself on the market.
This technology to increase driving safety and dynamic performance has, however, found no acceptance in the car world – assumingly early on for lack of dynamic requirements, later for reasons of tradition.
Clarity and intuitiveness are key for functional and operating safety of the gear shifting mechanism: the one-dimensional movement consisting of one section only and the clear distinction between upshift and downshift make all the difference.
The manalog SQS technology follows the principle that upshifts are performed by pulling the gear lever backwards and downshifts are conducted by pushing the gear lever forwards. Thus the hand follows simply and naturally the inertia forces when accelerating or braking, respectively.
Huge and yet untapped potential benefits for the environment are slumbering in manual transmission technology:
The number of forward speeds is of great influence on the fuel consumption and exhaust emission characteristics of motor vehicles. Of course, modern automotive engineering has understood this benefit. As a consequence automatic transmissions are currently on the market with up to ten forward speeds.
However, because the number of forward speeds is mostly seen reasonable up to only six for reasons of usability, manual transmissions are largely excluded from this positive development.
This is despite the fact that manual transmissions are mechanically more efficient, substantially lighter weight, more compact and also more cost effective than any other transmission technology. In addition, manual transmission technology also still represents a significant market share in many countries in the world, thanks not least to the genuine fun to drive they are able to offer.
manalog have developed the key technology to unlock these potential benefits in volume production vehicles and enables manufacturers to offer seven, eight or nine forward gears in manual transmissions. Using the manalog technology combined with multi-speed manual transmissions it is possible, extrapolated for Europe, to save megatons in greenhouse gas CO2 which is responsible for climate warming. Equally fuel consumption and other exhaust emissions can be reduced.
Last but not least, the convenience on a long distance drive can be improved considerably by reducing engine RPM and, as a consequence, noise level. This means a benefit for the environment and an increase in traffic safety due to a less tiring atmosphere for the driver.
