"...although it is a Porsche, and not a Maserati."A more useful guide might be range on a full tank. The GS has an 88 litre tank. It gives it a range of 300 miles with reserve warning light coming on at 280 miles or so. The Porsche Turbo also has a 300 - 320 mile range. But it has a 65 litre tank and comfortably does 24-28 mpg and long journey cruising steady on motorways returns 31/33 mpg and it runs 450bhp versus the GS 400 bhp.
Don’t know how you’re getting those figures Richard! Drive it like a nun I couldn’t get them in mine
Thanks, my circumstances are similar to this and I’d be fine with 17 mpg.I have driven about 40k miles in a 4200 in about 1.5 years. it's my daily driver.
the avg mpg after a week of commuting is 17.7 mpg or 6.3kpl. this is 80% highway.
the best I can get is cruising at 50mph. I get 26mpg. there is absolutely no way to get that higher.
As long as your car has a higher mpg figure than it’s number of cylinders, you should be fine. And the GS does. Unfortunately some of mine don’t fulfil that criteria
Thank you, that's incredibly helpful and very closely mirrors my commute, (apart from the distance). I drive between 30-80mph on dual carriageways / A roads and in the worst case scenario have 9 stop/starts. I'm fine with about 17mpg so your findings are very encouraging and in line with what I was hoping.Did some research for you this week. I'll mention it as these better than I was expecting...
Drove to the coast and back, total 160 miles. Outward was about 70% dual carriageway, 30% a and b roads, slow through villages but very little actual stop-start.
Return was a roads, no dual carriageway, some twisty stuff, varying mostly 30 to 80 mph, again little stop - start. No redlining or 'enthususstic' driving (was with wife....)
Average after all that was 17.7 mpg, flickering occasionally to 16.4 mpg....(nb they do this.... But it was mostly on 17.7)
As I get 12-13 urban commuting I considered this better than expected and I suppose the key is, don't stop and start much...

Am I right in thinking that the 4200 mpg displayed is US gallons?

Wow, I have no idea! In fact, I kind of, sort of, didn’t know the yanks had a different gallon......
Sorry if that makes my contribution completely redundant...
