Very confused by the actual CO2 rating of the 1.4 TSI.  In the brochures and on the web-site it says 121g/CO2.

 

However, if you configure an Octavia Elegance (on UK Site) it says it is 119g/CO2.  Interestingly however, if you configure an Octavia SE with the same engine is says 121g/CO2.

 

Now I hopped on to the Skoda Ireland web-site to see if it was a data entry error, but bizarrely all the 1.4 TSI Octavia models you can configure all show as 119g/CO2 there.

 

Anyway, reason I need to know is I'm considering the Elegance with 1.4 TSI as my company car and 119g is a band lower than 121g, so it makes a difference.  Really hoping I can get to the bottom of this and work out what the current official CO2 actually is 

 

If it is indeed the band higher I may instead consider the 2.0 TDI SE Business but then I'd lose the alcantara seats and 17" wheels, and it seems the 1,4 is somewhat more refined.  I don't do much private mileage so fuel consumption isn't much of an issue to me from a personal standpoint.

Parkers has got the 1.4 tsi manual down as 121g/co2 and the dsg version at 116g/co2 elegance spec, autotrader also states 121g/CO2 for the elegance manual version so looks like you might be stuffed, unless of course you go dsg. 

It does seem weight plays a big part in CO2 output.

 

just adding a spare wheel meant i would need to pay extra car tax with my TDi. Silly really.

Interesting that Dsg makes a positive difference. I remember the tdi vrs being about £100 more road tax for the Dsg as it adds a fair amount of weight.

Same with the golf gti/r (can anyone guess what I want next )

Surely this will be somewhere on the governments files if they're the ones taxing you to drive the thing.

Edit. Uk gov says 121

Edit 2

116 for Dsg.

The difference is probably that the VRS DSG is the heavy wet clutch (oil filled) box and the 1.4 uses the newer dry clutch box which is much lighter and therefore lighter and more efficient overall than the same engine with a oil filled manual box

I reported this exact same issue to Skoda CS a couple of weeks ago. I currently own a 1.4 TSi SE manual hatchback (purchased October 2013). The car configurator shows 119g/CO2 when I specced it but my V5 certificate shows this figure as 121g/CO2. The bottom line is that it is a band higher for VED. They said they were going to correct it doesn't look like they have yet.

Main reason I test drove the 1.4 TSI DSG was the fuel saving from the 7 speed DSG, in repacing a manual 2.0 TDI the 1.4 TSI DSG drove so much nicer and I swear its quicker of the line than the manual but, thats not supported by the Skoda data which has been shown previously to be manipulated.

Thanks for the responses

http://carfueldata.dft.gov.uk/search-new-or-used-cars.aspx  is the definitive place to find co2 or ved rates - they are the government's vehicle certification agency and all registration/taxation depends on their data

New member here - sorry to exhume an oldish thread but thought I could add to this. Yesterday I picked up a 1-year old Octavia estate 1.4tsi SE. Was expecting 121 gm co2 and £110 tax, but was delighted to find that on the registration document it is listed as 119gm co2 and therefore £30 a year. Nice - and unexpected - extra bonus! It's a manual with the 16" steel spare wheel as an option. The dealer didn't have an explanation for the differential between the brochure and the reg document.

 

I would suggest though that you check with your supplier - please don't use my one-off experience as definitive across-the-board evidence.

I just checked my V5C, dated 23-10-14 and it also says 119 G/KM for CO2.

Is that all they go by to set the tax rate?

I've emailed DVLA to clarify this. I suspect that the V5C hasn't distinguished between DSG and manual, and that the true figure will prove to be 121 (£110 p.a. tax) in which case I wonder if they will want to replace all the V5C's that are like that.

I was expecting 121 on my 2014 1.4 SE Estate and was delighted to see 119 on the V5. Looks like it's pot luck but there must be a reason for this!

Maybe the SE models with 16" wheels are 119 and the Elegance models with 17" are 121?  This was never stated in the brochure AFAIK.  My 17"-shod manual 1.4 TSI Elegance is definitely 121g/km on the V5.

This sounds plausible - though maybe as much to do with tyre width than diameter as I'd expect the overall wheel+tyre diameter to be comparable with the 17" Elegance. Not sure whether to look a gift horse etc by seeking clarification or just enjoy the bonus while it's there!

 

Certainly everything I'd read before buying led me to expect 121 gm rating, and no variation between models papart from DSG/manual: WhatCar, Parkers, Autotrader and the Skoda brochure itself. Which is most likely where the others got it from.

Why would wheels affect the CO2 output anyway?

A wider tyre would increase rolling resistance, also a larger wheel may be heavier....

Why would wheels affect the CO2 output anyway?

Narrower wheels have lower rolling resistance through smaller contact patch and less aero drag (tiny bit less) and steel 16 inch rim and tyre weighs 5kg less than alloy 17 inch and tyre (4x5kg=20kg). That is why a Prius has narrow tyres.

Another 1.4tsi manual se estate with 119g/kg on the v5 here. Dec 14 registration. I too was expecting 121g/kg and £110 tax. Will be interested to see the DVLA response.

But surely the CO2 depends on the engine, whether it is on wide wheels or narrow wheels.

If that is controlled by "drag", in other words how hard the engine is working, then surely the engine will have an almost endless variation in its CO2 output according to speed, road conditions, gradient and all the rest.

Which reading do they choose for the tax band? (I'd like it to be at a standstill with the engine turned off :-)

Come to think of it, if it were dependent on wheels and tyres, surely you would have to notify DVLA if you mildly modified your car by changing OEM wheels for bigger ones you preferred?

The May brochure says:

"Depending on your chosen wheel size, different efficiency figures for CO 2 emissions and fuel consumption will apply (based on EU directive no. 715/2007 effective from 01/09/14).

Please note that any change to alloy wheels could result in different efficiency figures, and as a result, the VED band that your Octavia falls into may increase, along with BiK tax."

The CO2 figures are for the car, not the engine, which is why the same engine gets different figures in different cars, or even different variants of the same car. The CO2 emissions are pretty much proportional to the fuel consumption.

And there you have it. Well spotted.

So is an alloy wheel considered less efficient at reducing CO2 than a steel wheel?

 

Ah, an EU directive. Now I get it. Like when you open a dustbin, rubbish falls out........!!!

So 119g/kg and £30 tax is correct then? That will make me even more impressed with the car. A 400+ mile motorway round trip at a good speed with 4 occupants and luggage yielded 45mpg a few weeks back. I think that's pretty amazing for a petrol car of that size!
