Is it worth paying extra for the 75 PS instead of the 60 PS? What's the actual difference in performance? The 60 PS I tested certainly lacked that va va voom.
The 75 ps isn't going to snap your neck when you drop the clutch but it does have 15 ps more than the 60 has but if it's only fuel economy you're interested in then you'll stay with the 60. There's not a huge difference in the fuel efficiency of the two motors anyway so for that reason I went for the the extra 15 ps.mazzarati888 said:Is it worth paying extra for the 75 PS instead of the 60 PS?

You need to hit 6200rpm before all 74 horses are released 200 rpm up on the 60. From what I know the two engines differ in the tuning of the ECU and nothing more.

I'm not sure I agree with you there. The quoted torque is the maximum value. I would suggest that the 75 has a broader torque curve which helps with it's improved acceleration. Also I would suspect the torque in the 75 is higher in the 60-75 mph area to give a more relaxing motorway experience and the ability to maintain speed at 70 up hills. The revs are not in the high torque area at 70.
I hope I am right or I will be disappointed.
Hi Gunter, Thanks for your words. I still don't understand your explanation! can you give me a source that shows/explains the torque/power curves in a way that I will understand. As you've explained it the 75 car suddenly gets 15 horse power between 6000 and 6200.GunSpeed said:<div style="margin-left: 2px; margin-top: 2px; margin-right: 2px; margin-bottom: 2px; font-family: Verdana, Arial, Helvetica, sans-serif; color: rgb0, 0, 0; font-weight: normal; font-size: 12px; line-height: 1.4; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; -: none; : rgb255, 255, 255; "><div style="margin-left: 2px; margin-top: 2px; margin-right: 2px; margin-bottom: 2px; font-family: Verdana, Arial, Helvetica, sans-serif; color: rgb0, 0, 0; font-weight: normal; font-size: 12px; line-height: 1.4; border-top-width: 0px; border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px; border-style: initial; border-color: initial; -: none; : rgb255, 255, 255; ">As said here above the torque is the same on both engines but apart from that both engines have their own transmission ratio's. The 75 shifts shorter than the 60 which means that at the same speed and in the same gear the 75 makes more rpm than the 60. This results in more torque and hence a swifter acceleration. Not only do you gain 1 sec from 0 - 100 km/h but more importantly you gain 2 sec from 80 - 120km/h (which comes in nicely when overtaking)... The fifth gear seems to be the same though and the diference in topspeed is only due to the 15hp more attained at higher rpm.Only downside to the 75 is the slightly higher fuel consumption.
The 60hp is as fuel-economic as possible and the 75hp drive a bit more flexible (less gearshifting)

I think there should be anew branch of tuning going around. One to suite our nice little cars. Titanium body shells, you know something simple. I know Audi tried the aluminium A2 that didn't sell well. The VAG group seem to have got it right this time.

Never said that they have different gearboxes?? What I said is that there is a difference in the transmission of the power. This can be achieved by two things : gearbox & differential...
Believe what you want but I found that paper a valuable piece of work that mostly confirmed my experience with both cars. (just my 2ç)
Possibly here. Either way, it's very edifying (with some help from Google Translate). To summarise, at the risk of repeating what's already been said in this thread:GunSpeed said:I found the full explaination with charts somewhere on a german forum
In fact, now I've finally got mine+2/3 e said:the final drive ratio has the 75 revving 7% higher for a given gear and road speed (assuming the same wheel diameters). (Presumably the 75's higher revs make for a very slightly less relaxed motorway cruising experience soundwise than in the 60.)
