Flat out as close to the red line as possible sounds like the best plan. It is also important to remember lots of smoke coming from the rear tyres is a sign of a good economic driver.
 
And always use the clutch downhill!

Actually, no. If you have the clutch in, the engine is forced to use a little bit of petrol to keep the engine idling. Any fuel injection car beyond the early 90's will likely have a total fuel cut when you're off throttle, using no petrol at all and using the momentum of the car to keep the engine turning over. Stick it in a high gear to minimise your speed loss.

Keep it in gear and rolling.
 
This kind of challenge looks cool to me.

The funny part is that they decided to implement it now, that Top Gear is gone. I think that it would be cool competing against the Top Gear trio in this kind of event.

My strategy? Half throtle, medium range RPM. No hard braking, no hard on gas.
 
I tried low revs in 6th in my car.. at certain speeds below 60 mph 5th gear is the most economical.. go figure! thus higher revs compared to 6th gear (obviously)
Yep.

The rule of thumb is 10mph/gear for constant speed - so you shouldn't use 6th gear for constant speed until you're over 60mph. This works on just about anything, but there's the odd car with weird gearing where you need to get inventive - but anywhere around the 2krpm mark is going to get you the best efficiency you can get.
 
Avoid braking is my stratagy.I don't want the energy spent putting the car moving dissipating as heat produced by braking, after that I'll see how I drive

Indeed, but I suppose with turbo engines (or even variable gemeotry turbos) we will have to get very experimental.. very interesting :-)
 
Without knowing more about this challenge we have to do a little guessing.

If it's a race against the clock, then being smooth on the throttle and not wasting any momentum will be key.

If this is going to strictly be about distance, then idling out, grab the next gear, idle out more (build a little more speed), repeat until car will not go any fast while idling, might be a good choice.

Are there obstacles to contend with?
Is it race? Cars? Time?
Hills?

There just isn't enough information, yet.
 
Find a fuel efficient car, keep it around 100km/h, find the optimal RPM range in the highest gear if possible.

Or just use the Veyron, floor it until it reaches the highest speed possible and then just cruise in neutral :D

I guess it depends on the track too. My thoughts are that it will be SSRX. If that's the case, the uphill section will be a bit of a challenge.

Okay Rihana

Try free wheeling by knocking a manual vehicle out of gear - I do this often and it saves a ton of fuel. On the level or downhill.. even engine ticking over you are using next to no fuel at all.
 
@Magic Ayrton : Indeed. The thing with the car in gear is that the car just slows down so fast. When you keep the engine ideling, it just doesn't use much fuel. And the car will be driving for a very long time. So I believe when you keep the car out of gear, you will save fuel.
 
The best fuel saving: GT6 should have an ignition switch. :D:lol:
How to drive very fuel effecient:
Drive like a grandpa with an egg behind the throttle and brake. Shift at 2000 revs.
Whenn going down hill select neutral and switch off the engine. :D
When you are at 80 kph again, you switch the engine back on and put it in the sixth gear. :D :eek::lol:
 
Oehh Race fans heaving a big discussion about how to drive fuel efficient. Quite hypocrite actually... :D:lol:
Shouldn't we go to the Toyota Prius forum with this question? :lol:
 
It all comes down to what car are we given and what track are we Eco-cruising on. Whenever if it's a C7 Vette at Brands Hatch or a Pruis at Bathurst. The real question is though, What happens when we run out? :odd: Silly question I know, but in the GT world it's a good one. :lol: Does the event end the instant we run out or does it end when we stop completely? Food for thought. :sly:

I was just thinking that. If the challenge ends when you go to a dead stop, then I keep my Veyron theory (if we are able to choose the car). Just gun it until it runs out of gas and keep on going.

But most likely we won't be able to choose cars. And I bet it will be in SSRX.
 
If my car was in Gran Turismo (the predecessor and successor are both in the game), I'd probably accelerate up to 110km/h and keep it steady there, and stay in 5th gear. That's when my car is the most fuel efficient. 0,5-ish litres per 10 km.

When you switch the ignition back on, bump start the car in the appropriate gear as you approach a suitable corner reducing speed and also saving battery power which would of consumed more fuel to recharge the battery due to the voltage drop you would of had turning the engine over with the starter motor (deep breath) :nervous::embarrassed::lol:
 
Get out, and push the car for a while, then get back in and drive until it runs out.

I won't push it if it weighs more than 1.5 tonnes though, I'll just get out and walk, saves the planet too.
 
For real life if you try it when you switch ignition off, remember to switch it back to position 2 or the steering wheel will lock. Also you need to press very hard on the brake pedal as there will be no assistance. Sometimes you need to use handbrake and foot brake to slow down. Obviously it comes with risks.
 
Avoid braking is my stratagy.I don't want the energy spent putting the car moving dissipating as heat produced by braking, after that I'll see how I drive

This, coupled with low revs, should help achieve some good economical runs 👍
 
yes but you will go further out of gear! due to frictional losses and engine braking..

But it would be using gas, as opposed to nothing at all.

Pulse and glide is the way to go, even better if you can turn off the engine.
 
Flat out in the most powerful car I can find on the straightest, most downhill road I can find.

Actually my second option would be to use the space rover and the moon. It still counts right? :sly:
