MPG - Again :-)
According to Fuelly, my T5 is averaging 31.7mpg after 7500 miles. Volvo On Call App is claiming 35.7mpg!
T5 FE Bursting Blue, 19" wheels, no headlamp cleaning. Ordered 24 February, arrived at dealer 25 April, delivered 30 April.

i have a T4 R Design and after extensive testing by volvo the best they got was 21 mpg
Had my RDesign T4 for 10 days now I am averaging 34mpg with mixed driving town and motorway used eco setting most of the time and considering it’s a new engine I am more than satisfied, after reading some of the horror stories on this forum mileage at present 295

Just a couple of points guys.
Obviously how you use the car will have most effect on mpg but the mpg will always be higher in summer. Also I garage my car each night and this beats keeping it on a frosty drive or street (I live in frozen North East England!) so where you live has an effect. I measured at least 3 mpg extra on account of these variables eg warm garage and summer temperatures.

I suspect that part of the extra consumption in winter may be due to extra performance being available. The colder denser air will allow more charge into the cylinder; obviously this is controlled to some extent by the engine management system, but if you start off with colder denser air then it seems likely to me that you'll also see a degree of extra power per bang. Would be interesting to see equivalent 0-60 times measured in summer and winter - wouldn't be surprised to see winter times being eg 0.1-0.2 sec better, assuming both were done on dry roads etc.
In winter there's also maybe more chance of wet roads with increased tyre drag and hence more fuel consumption. This effect is a bit more obvious with EVs where you get an instantaneous readout of power consumption but the same effect must apply to fossil cars too.
It also takes more energy to get the engine up to temperaturejohnd wrote: ↑Mon Feb 25, 2019 9:51 amI suspect that part of the extra consumption in winter may be due to extra performance being available.
