Since there is no mention of a budget, I suggest a new BMW M5. These will comfortably eat your 500km each way, and you'll always arrive in comfort and style. Great for the family too.

For economy, the Audi A8 TDi V8 gets 7.6 l/100km, and will accelerate 0-100 in 5.5 sec. These would also be a great long distance cruiser. They are, afterall built for the autobahns.

However, if you're not an Audi or BMW fan, then you'll just have to settle for the Merc S63 AMG. A bit thirsty, but will accelerate to 100 in less than 5 sec, so safe for overtaking those road trains out west.

Hope this info has helped you, Adam.

can someone explain why a large car is more fuel efficient on highways/long distance trips?

They aren't necessarily more efficient, but there's far less difference between a big and small engine when a big engine is just loping along at a constant speed well within it's ability. The torque helps, too. More go at lower RPM means lower overall gearing and lower revs as cruise speed which equates to lower fuel usage.

yeah it's a mix of more torque, taller gearing, inertia and general physics. most large cars are generally detuned quite as they are designed to be good at highway cruising (hence why plenty of falcadores will get better economy on the highway than a more highly strung natro skyline). and the fact that the amount of extra power required to hold an extra few hundred kgs at 100kmh isn't that much. so not much extra fuel is required.

the best economy i've gotten out of the missus SSS was 6.5L/100kms, but after driving it to work the other day, it reminded me just how much more comfy the seats are in the commodore. and the general driving position for that matter. not as nice/fun to drive, but much more comfy

    • Hey lads, reviving an old thread.  As an update, since the last time replied to this thread, ive done mostly suspension. Havent touched the motor except for maintenance. Though upon changing spark plugs, found out i had splitfires pre-installed! Updates: - Got me some stock airbox top cover and snorkel to fit onto the original intake. Should be free of defects - Bought a set of R34 GT-T brakes (not installed yet, going to rebuild + respray in champion blue + white 'Nissan' text) - Bought the last set of bilsteins from @Sydneykid and had them installed. Has been making some sounds on the rear but hopefully should be sorted out after this New Year break. - Regreased front caster rod bushings (poly bushes..) - Rear upper camber arms - Whiteline sway bars (BNF27Z 22mm + BNR11XXZ 24mm).  The rear sway bars are a bit short (ive read 50mm else where) but was still able to get them in.  Anyhows, I reckon suspension is sorted now. Maybe replace bushes (do have a set of front upper control arms from SK not installed yet) but should be okay for now. From now, I'm wanting to start working on the motor, drivetrain etc etc. Still debating on the order to go on and what to buy etc but: - ECU ( Haltech or Link ( Link states that it dont support A/T or AWD functions... Can anyone attest to this? ) - Highflow turbo ( ATR43ss2 ) - Intercooler ( Not decided yet, but cant find many good afoordable ones. Toshi says to opt for crossflow Japanese. Bit difficult this one, unless I get a returnflow Blitz from JJ? ) - Injectors ( Any recommendations ? I do have a nismo FPR ( Thanks SK ) ) - Seats - Tune by either Toshi or DVS To be fair, I did consider just keeping the stock turbo and nistuning it. Sat in a mates stock N, that had something like 200kw, and I reckon that felt more than enough. Maybe I should just go this route ahhaha. Too many choices.... Planning a trip down south, so wanting to just clean things up and make sure it gets to and from in one piece. Anything else specifically I should do before ? Cheers lads  
    • Must be for the car’s lucky charm 🤷🏽‍♂️ She runs fine, but it just seems to take about 1L less. Maybe I’ll have the oil sump dropped at some point to check if there is anything
