Mitsubishi Motors has unveiled two of the technologies that will go into the upcoming 10th in it’s generation Mitsubishi Lancer Evolution, but let’s talk about them one at a time. We’ll have a look at Twin Clutch SST (Sport Shift Transmission) first – an automated manual transmission with twin clutches much like Volkswagen’s DSG, the current benchmark for dual clutch automated manual transmission.
Much like DSG, Mitsubishi has upt the odd gears (1st, 3rd and 5th) on one clutch and the even gears (2nd, 4th, and 6th) on the other clutch. Under precise system control, the gearbox swaps between gears much faster on the upshifts as the next gear is preselected.
The Twin Clutch SST system has three shift programs – Normal, Sport and S-Sport. Normal mode like it’s namesake is for normal driving around town and highways. It uses low shift points for better comfort and fuel economy.
The Sport mode is to be used in situations like mountain driving, or whenever you need lots of engine braking, keeping the gears in lower ones for longer than normal. Shift points are also higher for more power. S-Sport mode is the mad, rapid, rev to redline mode with the fastest possible shifting.
Mitsubishi did not release the shift times for the Twin Clutch SST so we don’t really know at this moment whether it is faster or slower or equal to Volkswagen’s DSG.
