A factory V8 will never do that... A V8 with an economy tune and some fettling will...
They need a centre muffler to not sound obnoxious or droney (straight through being obnoxious, rear res in place being droney).
Remove the rear res and fit a high flow centre muffler and they are sweet as pie...
My RV8 makes the Falcodore guys jealous with how smooth it is right through the range...
Running 18" rims and odo works fine.
ive achived 11l/h
i did drive at 70km/h though
I have also achieved that at a constant 60 or 70 kph but sorry I dont accept an average around town or at highway speeds of 11l per 100 k and not much more when towing. I have high flow cats, free flow muffler etc. Even when my truck was new and just under 2 tonns and empty, no bullbar etc i did not average 11l per 100k. 14 was the best. I have never heard of 11 as an average so this is quite the revelation .
Cheers
And a 5 speed manual gets better economy if driven well.than an auto. Cheers
Ps MRLR what fettling saves 2-3 l per 100k...i would think at least new cast heads from the UK, roller rockers, flow tested fuel injection tune...even then i would be dubious.
Make it breathe properly, and a quality map and maybe cams if you want to get fancy...Quote:

It's speculation and I don't know anyone who has achieved the best of both worlds,

From a site called car data for a 9.35 CR. D2 These are official figures so can be construed as pretty much the best you could get.

Fuel consumption (economy) - urban 23.3 (22.9) l/100 km.https://www.aulro.com/afvb/images/im...016/02/689.jpg Fuel consumption (economy) - extra urban 12.7 (13.1) l/100 km.https://www.aulro.com/afvb/images/im...016/02/689.jpg Fuel consumption (economy) - combined 16.6 (16.7) l/100 km.
And Phillip like all car companies they are simply not achievable in real life.
Cheers
I meant to be tuned for economy...Quote:
