The sound itself is the result of the engine computer pulling timing from the ignition cycle when the shift occurs This allows the engine RPMs to fall appropriately, the shift to occur, and for the next gear to be engaged smoothly. Similarly, it is about two-tenths of a second faster in the quarter-mile, averaging 14.3 seconds over 14.5 for the manual transmission Mk7 GTI.Īlthough this is fairly muffled on factory vehicles, the more free-flowing the exhaust, the more likely you are to hear it. How much faster? Depending on the exact trim level, the DSG equipped Mk7 GTI is about two-tenths of a second faster to 60 miles per hour at 5.8 seconds on average, compared to 6.0 seconds for the manual. A DSG transmission can perform a complete shift in around 200 milliseconds and can shift more quickly than the best drivers in a similar manual transmission vehicle. It also will make the shift to the next gear more quickly, with a faster and more abrupt engagement of the clutch. However, if you press the accelerator pedal down like when you merge onto a busy highway, the Mechatronic unit sees the increased power produced by the engine and holds the gear longer, or performs a down-shift depending on the current gear and RPM, ensuring faster acceleration. A DSG-equipped vehicle driven gently will use less fuel than the same car equipped with a manual. It also knows how hard and fast to make the shift, and if it should upshift or downshift, using the same sensors and parameters.įor example, if you're just easing along in traffic and not accelerating or braking with a lot of force, the transmission will work its way up or down through the gears easily, ensuring smooth performance and shifting at low revs to maximize fuel efficiency. The Mechatronic unit can guess with remarkable accuracy which gear you're going to want next, whether you are accelerating, braking, or cornering. It has a variety of inputs to decide how and when to shift, such as vehicle speed, engine speed, throttle position, brake pressure, and g-force measurements from the accelerometers in the car. This transfers power from the engine, through the transmission, and finally to the drive wheels.Ĭonnected via the vehicle's computer CAN bus system, the Mechatronic works in conjunction with other control units such as the ECU (Engine Control Unit) and the ABS braking system. Much like a standard manual transmission, a DSG-equipped vehicle has a flywheel, which mates to the input shaft of the transmission, and is engaged by a clutch. Rarely has one component been able to increase both efficiency and performance with almost no downside.Īll Volkswagen DSG transmissions are a transaxle design, which means that the same transmission case houses both the gears, the final drive, and differential in one unit, with shared oiling and lubrication. DSG and DCT transmissions have been a game-changer in the automotive world and in performance circles. DSG transmissions can be operated in a fully automatic mode, where the computer decides when and how to shift, or in a semi-automatic mode, where the driver uses either the gearshift shift lever or steering wheel-mounted paddles to select the desired gear. For instance, choose Fill Months to increase the month value in your date series.The DSG combines the best attributes and efficiency of a standard manual transmission and the ease of use of a more traditional automatic. When you do, Excel displays a context menu. Using the right mouse button, drag the fill handle down several cells and release.Select a cell and press + to enter the current date.If, on the other hand, you use the right mouse button to drag the fill handle, you’ll get a whole lot more. Using the left mouse button – the normal process – creates the incrementing day series. There’s a lot of built-in flexibility to the fill handle, if you know how to access it. So, if you enter 8/8/11 and use the fill handle to create a date series, you end up with 8/8/11, 8/9/11, 8/10/11, and so on. Using the fill handle increases the date by one day. You can then create a date series by copying that single date using the fill handle. For instance, you can enter the current date by pressing + (that’s a semi-colon character). There are a number of quick tricks for entering dates, especially if there’s some kind of pattern to the date values you’re entering. Susan Harkins explains how to use these simple tricks to enter date values quickly and intuitively into Microsoft Excel. Enter date values quickly using these Excel tricks
