Steve Rogers Posted May 18 Share Posted May 18 Can anyone with an A4 35 or 40 TFSI please advise me on the following?: 1: How much does a full tank cost with say Esso or BP rather than Supermarket fuel 2: What MPG do you tend to average with mixed driving? 3: How many miles do you get from a full tank? I have the 35 TDI so I am purely curious as to real world differences. Thanks Quote Link to comment Share on other sites More sharing options...
Magnet Posted May 18 Share Posted May 18 Hello Dave, Tank capacity is 54 litres by what I understand, so you a work out how much it will cost to fill the tank - based on the cost/ltr. in your area for the fuel brand you choose. Hopefully you will get responses to question (2) which will allow you to work out the answer to question (3). Kind regards, Gareth. 1 Quote Link to comment Share on other sites More sharing options...
icstm Posted May 27 Share Posted May 27 On a good run including a good chunk of motorway and country lane driving, before back into the city my 40 TFSI can get 45mpg. That same route with more traffic in places and a heavier foot in others still is almost 40 mpg. In traffic at crawling speed which we suffer often, it can be below 20 on a short drive. What are you getting? 1 Quote Link to comment Share on other sites More sharing options...

That same route with more traffic in places and a heavier foot in others still is almost 40 mpg. In traffic at crawling speed which we suffer often, it can be below 20 on a short drive. What are you getting? Thanks. That's really good for a 40 TFSI. I typically get between low 50's and low 60's depending on how and where I drive. I have had 75mpg on a good run. With the fuel tank being quite a bit smaller than the petrol, I calculated how much it would cost vs petrol for a full tank from empty and then topping it up by a further 14 litres for the same amount of fuel as the petrol car can hold. So petrol would cost £79.38 and diesel £83.16. A conservative estimate for miles from a full tank vs a 35 TFSI, and being slightly biased towards the petrol with the estimate, sees 513 miles from the diesel vs 432 from the petrol.

axelz Posted Wednesday at 03:14 PM Share Posted Wednesday at 03:14 PM (edited) I'm getting around 25-30 with town/short journey driving, 40-45 ish on the motorway. TFSI 40 A4 Avant. Thirstier than my previous B8 TDI 2.0 A4 Saloon but it's also automatic which the old car wasn't.

As they are not torque converting automatics, but are automated (dual) clutch based cars, do we still expect a hit vs manual? Quote Link to comment Share on other sites More sharing options...
axelz Posted Wednesday at 06:54 PM Share Posted Wednesday at 06:54 PM To be fair, I can't directly compare petrol with diesel anyway.. a good point though it's not like the old automatics.... Quote Link to comment Share on other sites More sharing options...

The DSG should be comparable to a manual change box in terms of power transmission efficiency. One of the incentives to develop DSG was to eliminate the hydraulic slip associated with torque converters. (As an aside I might add that later torque converters sometimes had a device to lock the TC at high speed, thus reducing the overall loss.)
