2008 Porsche 997 Carrera 2

PostPosted: Tue Aug 21, 2018 10:47 am    Post subject: Porsche vs Aston Fuel consumption. Reply with quote

6 weeks ago I took my 997.2PDK Cab to Rome and back (3,000 miles) and averaged 27mpg.




In 3 days time, I'm taking my 6.0l V12 Aston DB9 Volante and my daughter is driving my 2.7 Tiptronic 987 Boxter to the Italian GP and back.

Both cars will be driving the same roads at the same speeds, and both of them will have 2 people in them with full luggage.

I reckon the Boxster will do the same as the 911, as its smaller and lighter but does not have the 911's more efficient DFI engine and PDK, and the Aston's fuel bill will require a re-mortgage Wink.

Shall we all have a guess to the difference in fuel?

Its a long run so the DB9 may be quite efficient like 24mpg lol, unlike the 14 to 18 mpg you get around the town . ate you running it on super or regular and are there differences between fuel quality in southern France and Italy. when we went to Germany to had a list of the shell stations enroute so we could keep it vmax

You could be into the teens with that V12

I’m putting normal 95ron in it and on a long run doing 70mph I average 28mpg. Was thinking the same prob 24mpg at 130kph

How are you going to measure the mpg? As car trip computers aren't the most reliable. There are several good iPhone apps.

The old fashioned way. Fill up before we go, then devide the total amount of miles over the fuel spent (keep the receipts).

150 miles into France doing a nice and easy 70mph and the Boxster engine pumps out clouds of white smoke then dies. It’s covered in oil and looks like it could be the 5th replacement/rebuild in 8 Cars. Not a good average.

We now wait for the police to remove the car form the motorway slip road, then we have to contact the RAC to get it recovered back to Porsche Torque.

The Aston has been fine.

Very sorry to hear that Les. Hope it is just the AOS or something else not too pricey.

Oh no, sorry to hear this Les. Looks like its 4 for the road in the Aston. Least you got further than Chris, he's stuck on the M1.
