ZF added that the TraXon has a high transmission ratio spread
and an energy conservation efficiency rating of 99.7%.
Adoption of launch gears is being viewed as a viable approach for improving efficiency and improving ratio spread
of automotive gear, devoid of performance deterioration.
Largst block was a ratio spread
on NYSE-Arca where a trader sold 12500 July 44 calls for 50c and bought 6K July 45s for 17c.
The new transmission comes with eight forward gears as well as four reverse gears, higher overall gear ratio spread
, equal ratio steps between gears and optimized gear shifting with partial load shifts.
The 10-speed automatic transmission is an all-new design -- and the first-ever application in an SUV -- with a wider, 7.39 overall gear ratio spread
, that enables the Escalade's powerful and efficient 6.2L V-8 engine to achieve a more immediate feeling of performance.
Thanks to the wide gear ratio spread
, the decidedly high torque of the V8 biturbo engine can be used to optimum effect.
A wider, 7.39 overall gear ratio spread
, compared to the Yukon Denali's previous eight-speed automatic, enables a lower numerical top gear ratio and contributes to greater efficiency.
The additional technical details of the concept include a higher ratio spread
coming from an additional gear (5th gear).
As Figure 15 indicates, the lowest fuel consumption occurs with the widest ratio spread
of 10 through 12 speeds.
The model is to be equipped with a new continuously variable transmission with a ratio spread
similar to a seven-speed automatic transmission.
The savings are due to a high total gear ratio spread
(9.84), which means the engine is running in a more-optimal gear depending on conditions.
The latest versionof the Xtronic CVT technlogy now expands the gear ratio spread
from the earlier six to a world leading seven according to Nissan and this in turns not only provides good acceleration and driveability but also increases fuel efficiency, which according to Nissan engineers is up by about 1kmpl as compared to a 5- speed manual on the Micra, to over 19kmpl.
