I have a 2019 GS and was wondering if there is a RPM and Miles per hour for each od the 8 gears of the A8 trans as well as the differential gear ratios? The reason for the question is for shifting up or down in the manual mode.

 

From the Page 190/191 of the 2019 OM:The vehicle speeds required for Manual Paddle Shift upshifts depend on several vehicle inputs, which will vary the allowed upshift speed by a few km/h (mph).

For Vehicles with a 2.41:1 Axle Ratio (RPO GXB)

. Upshifts to 3 (Third) gear require approximately 25 km/h (16 mph).

. Upshifts to 4 (Fourth) gear require approximately 37 km/h (23 mph).

. Upshifts to 5 (Fifth) gear require approximately 48 km/h (30 mph).

. Upshifts to 6 (Sixth) gear require approximately 60 km/h (37 mph).

. Upshifts to 7 (Seventh) gear require approximately 74 km/h (46 mph).

. Upshifts to 8 (Eighth) gear require approximately 95 km/h (59 mph).

To prevent damage to the powertrain, Manual Paddle downshifts to a lower gear cannot be done above certain speeds. The maximum speed allowed for downshifting of gears 1 (First) through 7 (Seventh) are:

. Into 7 (Seventh) gear over 365 km/h (227 mph).

. Into 6 (Sixth) gear over 309 km/h (192 mph).

. Into 5 (Fifth) gear over 243 km/h (151 mph).

. Into 4 (Fourth) gear over 183 km/h (114 mph).

. Into 3 (Third) gear over 149 km/h (93 mph).

. Into 2 (Second) gear over 100 km/h (62 mph).

. Into 1 (First) gear over 62 km/h (39 mph).

For Vehicles with a 2.73:1 Axle Ratio (RPO GU2)

. Upshifts to 3 (Third) gear require approximately 24 km/h (15 mph).

. Upshifts to 4 (Fourth) gear require approximately 34 km/h (21 mph).

. Upshifts to 5 (Fifth) gear require approximately 43 km/h (27 mph).

. Upshifts to 6 (Sixth) gear require approximately 55 km/h (34 mph).

. Upshifts to 7 (Seventh) gear require approximately 64 km/h (40 mph).

. Upshifts to 8 (Eighth) gear require approximately 82 km/h (51 mph).

To prevent damage to the powertrain, Manual Paddle downshifts to a lower gear cannot be done above certain speeds. Themaximum speed allowed for downshifting of gears 1 (First) through 7 (Seventh) are:

. Into 7 (Seventh) gear over 321 km/h (199 mph).

. Into 6 (Sixth) gear over 272 km/h (169 mph).

. Into 5 (Fifth) gear over 214 km/h (133 mph).

. Into 4 (Fourth) gear over 161 km/h (100 mph).

. Into 3 (Third) gear over 131 km/h (93 mph).

. Into 2 (Second) gear over 88 km/h (62 mph).

. Into 1 (First) gear over 55 km/h (39 mph).

If an upshift is not requested as the engine speed approaches fuel shutoff rpm, the engine speed will be limited to protect the engine. See Tachometer 0 108.
