Can you describe the AT box performance (including the details on how good the manual mode is) for our reading pleasure? I just admire this concept of automatic GBs with manual mode - best of both worlds really - shift when you want without hurting your left knee. I wanted to go for one but when I bought the TSi, Skoda did not offer DSG on petrol Laura...and Cruze would be better - same concept and convinience but with traditional reliability of torque convertor. Are the shifts slow/noticeable? DSG is a magic on those two fronts. Also, some RPM/speed data for every gear would be very interesting stuff if you can share.
Enjoy miles and miles...

At the outset let me state that the Cruze's auto tranny is designed to just convert the car into an effortless cruiser rather than an enthusiastic driving machine. I think its biggest accomplishment is in getting rid of the highly pronounced turbo-lag that the manual Cruze is (in)famous for.
I guess the ECU manages gear shifts somewhere between 1600 - 1800 rpm. The shifts are very smooth and almost seems like a CVT due to the very long gear ratios. The power delivery is extremely linear unlike the manual which goes berserk once the turbo kicks in. Though the DSG provides a far superior driving experience, in terms of in-gear acceleration figures you'll find the Cruze auto tranny is almost as competent as the DSG from VW or Ford. I've heard that GM uses the same auto tranny in several 6 cylinder cars in its stable and the performance is pretty decent.
I presume that you already know how the tiptronic manual mode works. It just holds onto a gear till you effect a change manually and thereby provides more control. In the city driving conditions it is pointless to resort to this mode since it defeats the purpose of owning an Automatic at a higher cost. It makes sense only when you are caught up in slush or while driving down deep slopes. Once I got used to the luxury of Auto tranny & Cruise control, I haven't been tempted to use it at all. However, the fact that I can resort to it whenever the situation demands gives a sense of security. Further, the manual mode isn't as much fun to use as the paddle shifts on the Civic or City since you need to take your hands off steering wheel.
From an economy standpoint, while most Cruze AT owners on the forum have reported single digit mileage figures, I've a completely different experience to share. I generally drive 60% on highways and 40% within city limits. During the first 30,000 kms, I got an average mileage of 13.3 kmpl (In this period, barring three occasions, I always stuck to two-digit speeds). Between 30,000 to 50,000 kms, I starting pushing the car up to 160 kmph and got an average mileage of 12.4 kmpl. After crossing 50 K kms mark, I've done another 2,250 kms (80% in the city) and got an average mileage of 11.6. Perhaps the P1 and P2 modes in the recently installed dual channel RD box is also to blame
I've uploaded a picture of the speedometer (on page 4 or 5 of this thread) where you'll notice the car doing 120 kmph at about 1300 rpm. Obviously it should be in the 6th gear. Even I'm curious to check the Speed versus RPM in different gears. Let me explore this weekend and revert with results. |
