MPG When Towing

Perhaps that is because the pub doesn't have any litre or in your case half litre glasses. 

A half litre would be 68ml short 

We never worried about MPG when on a touring holiday with the caravan.  Suv's make great towcars but have the aerodynamics of a brick and we accepted that while towing, the vehicle would use more fuel than when running solo.    When the fuel gauge dropped, we topped up.  Never crossed my mind about how much or little the fuel for our chosen holiday was costing.

K, try this Maserati Levante-supreme aerodynamics

Some of these claims amaze me.  I am pretty light-footed (I currently average around 45mpg solo with a LR Discovery Sport auto which, from what I read is above average), but I recon I only ever get about 65% of solo consumption when towing.  My previous Freelander averaged around 38mpg solo but only 24mpg towing and prior to that, my Mercedes E class 2.2cdi would do up to 55mpg on a solo long run but never made it to 30mpg when towing.

I have a Jeep Grand Cherokee 3litre automatic that realises 21mpg. That is driving around town.

We have just covered 3000 miles down to Switzerland and Italy where we made 22 mpg.

Not very economical compared to the Kuga we had but with the Jeep we feel safe and secure towing our van and I felt less tired and stressed driving those distances.

Last time we towed with petrol was 2004 - 2l RAV4 - 25.2 towing, 41 solo. 1000kg van over 3 weeks.. with 2l diesel, with the same van and now a 1250kg van, it was 30/31 towing 55-61 solo. Just gone back to petrol, thus far 41 solo, but new car and only 500 miles so far, towing yet to be determined. do remember though, getting 29mpg towing in the mid 1970s from W Yorks up to the north of Scotland & back, Sprite Alpine behind a 1256cc petrol Viva.

I only used to get mid to high 20's towing a little Eccles with my petrol Mondeo.

I tow a 1,436 kg MTPLM caravan,- usually loaded to around its full permissible weight, and vehicle loaded as well - with my 1.9TDI Touran (max. trailer weight 1,500 kg).  Depending on terrain and wind conditions I get between 28 and 32 mpg when towing.  Solo I get around 50+ mpg, but the best return has been in France when the upper 60's was achieved.

l have the Santa Fe wiggins edition 2016 model and agree with the 75% that someone has stated l get around 25 mph that's on the cars computer, some of the figures l am seeing here l am sceptical about
