A mate is looking at one as a cost saving measure, anyone know the differences between the engines, they are both three pot 1.0 litre units but one has 59 bhp and the other 74, both have the same torque (70 lb/ft at same rpm) but the power is 59 bhp @5000 RPM versus 74 bhp at 6200 rpm, have VW just set the rev limiter lower on the same engine via the ECU or are there mechanical differences, is it like the Mini vs the Mini Cooper where it is just software or like the Rover K series which just had a throttle stop on the throttle body for a low tech power limit ?

Will be interesting to see if there is a cheap and easy way to turn a 59 into a 74 (or better)

Also, what do they drive like, we have a C1 we bought last year as a shopping car and to be honest it gets used the most now, I know the Up is newer and better than the C1 but how much, anyone driven both ?

He is looking at the Black Up!, the Al Jolson themed special edition (great for your Mammy), ok I know its called the Up! Black but there is little comedy value in that.

I HIGHLY doubt they have a different throttle stop for different power levels.

That is a horrific way of doing it. It'd ruin volumetric efficiency.

It'll be fueling and/or timing that changes it. All software.

Yep, I would hope they didn't resort to 1990's techniques, interested in whether it is purely software.

Give these guys a call:

They'd know for sure and prob try to sell you a clever little box they do that you can plug into the ECU and change the mapping from standard, to custom, to immobilised (for when you're leaving the car for a while).

Bit of info here.

Both cars have seem gearbox.

Seems to be just a remap on the ECU which I assume could probably be done aftermarket...? There is a dutch company that does it... http://www.venturatuning.nl/merken/chip-tuning-vol... so probably someone in the UK that can.


1.0 MPI with 44 kW / 60 PS

From its 999 cm3 displacement, this entry-level engine develops a lively 44 kW / 60 PS at 5,500 rpm. Its maximum torque of 95 Nm is available between 3,000 and 5,000 rpm. 90 per cent of maximum torque is reached between 2,000 and 6,000 rpm. This results in good agility in nearly all engine rev ranges. In the base version with the 5-speed manual gearbox, a combined fuel consumption of 4.5 l/100 km is attained, which is equivalent to 105 g/km CO2. For the version with BlueMotion Technology, the values are 4.2 l/100 km and 97 g/km. In conjunction with the 35-litre fuel tank used in the up!, this yields a theoretical range of 833 km. The up! with 60 PS and a manual gearbox accelerates to 100 km/h in 14.4 seconds and reaches a top speed of 160 km/h (161 km/h and 14.5 seconds as a BlueMotion Technology version).

1.0 MPI with 55 kW / 75 PS

The more powerful version of the 1.0-litre engine has the same displacement and same bore (74.5 mm) and stroke (76.4 mm) dimensions. The power gain is achieved by a modification to the engine controller. This results in a maximum power of 55 kW / 75 PS at 6,200 rpm. The maximum torque of 95 Nm is identical. With a manual gearbox, the 75-PS engine has a combined fuel consumption of 4.7 l/100 km (equivalent to 108 g/km CO2). The BlueMotion Technology version attains 4.3 l/100 km and 99 g/km CO2. The "large" up! with a manual gearbox has a top speed of 171 km/h and completes the sprint to 100 km/h in 13.2 seconds (174 km/h and 13.3 seconds as a BlueMotion Technology version).

5 forward gears - manually

The new 5-speed gearboxes, which are made out of aluminium, were specially tuned to the three-cylinder petrol engines. The conventional manual gearbox version, referred to as the MQ100, weighs just 25 kg including transmission fluid, which makes it the world's lightest gearbox in this torque class (the gearbox also comes with indicators for the recommended gear and the engaged gear in the instrument cluster as standard). The gearbox is also built very compactly with a length of 341 mm and width of 462 mm.
