Including the flywheel and clutch, the sequential weighs nearly 100 pounds less than the DSG, which is a huge amount for a race car. 250+ ratios, replaceable dog-rings vs gears, independent shifter barrels, rotatable forks, (12) inputs, 6XD can be rotate 90* for lower crank centerline to the ground! [9] Most racing cars also use a sequential transmission now (either via a sequential shifter lever or with paddle-shifters),[10] rather than the old H-pattern stick shift, beginning with the paddle-shifted Williams FW14 Formula One car in 1991, which used a sequential drum-rotation mechanism.[11][12].

This seems to be the more common technique because it has fewer parts and is more compact. This rotation causes the rods or forks to move according to the grooves in the drum, changing the gears. Ah, the sequential gearbox–which for many of us is somewhat mysterious. Sequential gearbox is stuff of the day in our sport, take rally, DTM, Formula 1, almost all open wheel classes, WTCC, Indy, truck racing... Sequential transmissions usually use the rotation of a drum to switch gears. [3][4], On a sequential manual transmission, the shift lever operates a ratchet mechanism that converts the fore-and-aft motion of the shift lever into rotation of a selector drum (sometimes called a barrel) which has three or four tracks machined around its circumference. On a sequential gearbox, you simply push the lever up for every gear change. Final drive ratios: 3.857 4.083 4.380 4.545 4.690 4.910 5.080 . You only need space for the forward/backward motion of the lever, not left/right.

Users of TTI gearboxes simply love the sheer strength, durability and … You always go to the next gear. The advantage of this system is that shifting mistakes are impossible. If the drum is located next to the gears, the grooves directly move the gear selector fork, and no control rods are needed. Gas-powered vs. Electric Cars: Which Is Faster?

It is a much faster way to shift. [2] The use of dog clutches (rather than synchromesh) results in faster shift speeds than a conventional manual transmission. To get to third, you shift up, to the right and up again. Due to the high rate of wear and abrupt shifting action, sequential manual transmissions are rarely used in passenger cars, albeit with some exceptions. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential shifter.
