Title: m.p.h Post by rich1 on Dec 3rd, 2008, 9:24pm had a nice trip to and from ipswich today (about 70 miles each way) and on the way back i stuck the cruise control on at 70mph and then put the trip computor on the one where it shows how many mph your getting and mine was showing 36.6 on average. is that good bad or average ?, i didnt think it was bad and my dad who drives a 4.0l jag said it was really good, what do you think? btw aint this sort of journey what the scorpio was made for (ive got the 2.9, 24v cossie estate) |

Title: Re: m.p.h Post by matt1987 on Dec 3rd, 2008, 9:54pm that is very good i get 20mpg around town and on a run i get around 28/29 on a 2.3 estate but that does include starting and stopping. on the car is moving it uses very little fuel it is the starting and stopping that kills the mpg |

Title: Re: m.p.h Post by rich1 on Dec 3rd, 2008, 9:56pm yeah when i got to ipswich town centre it dropped to about 16/17!!! |

Title: Re: m.p.h Post by Pegasus on Dec 3rd, 2008, 10:26pm doing a steady speed on cruise at 70 should give you those figures. If you want better, stick it on cruise at 50 - I got 40mpg :) |

Title: Re: m.p.h Post by lube-o-rific on Dec 3rd, 2008, 11:17pm Those are fantastic figures! 36.6mpg sounds very good and I would be pleased with that on a run. I'm averaging 17/18 mpg around the town at the moment myself. |

Title: Re: m.p.h Post by Baz on Dec 4th, 2008, 3:07am The last time I took my 24v to the south of France it cost me £600.00 in fuel for the round trip. (about 10 tank fuls for the two weeks away!!!) |

Title: Re: m.p.h Post by mr._floppy on Dec 4th, 2008, 6:10pm Are you sure you've got a 2.9 lump under the bonnet ? I've got a 2.0 lt Saloon and struggle to get 36 mpg at 56 mph on a flat Mway. ( I'm very popular doing that speed :-*) . |

Title: Re: m.p.h Post by pinto on Dec 4th, 2008, 6:26pm V6's are capable of unbeleiveable fuel economy if you treat them gently :) My 3.2 XR4x4 went to a car show from Rye to Mansfield near Nottingham last year and on the way up, I burnt a complete tank of juice to cover just over 240 miles (ahem :) ) Being short of funds, the return journey was made at a little over 60 mph and i made point of keeping the rpm below 3000 (which is where my engine, like the 24v, came "on cam") and made the same return journey for less than half the amount :) I assumed a "optimistic" gauge reading, but more gentle motorway work that week finally yielded 505 miles before i chickened out and filled up again ;D Based on the sierras 70 litre tank... that was 16 mpg playing and 33 mpg on the return leg ;) |

Title: Re: m.p.h Post by python9 on Dec 4th, 2008, 8:08pm went about town today got 22/23 mpg and then on a run for 60 miles at 60mph and got 39/40 mpg i think for a big motor thats a great return my car has done 55,959 miles |

Title: Re: m.p.h Post by scorpio_man on Dec 5th, 2008, 8:21am hi there remember all mpg figures need to be quoted with the mph figure. also the mpg figure will be a lot higher just after reseting the trip computer. this is based on, iirc, 500 miles. so in reality, using all engine types, the scorpio will return between 16-20 mpg (12-18 mph) in town to 27-40 mpg (60-65 mph) on a m/way run. hth |

[] but I was stuck in 5 miles of road works (still there 6 weeks later - I got same figure). I prefer to exercise the engine properly given the chance ;) As Andrew says - I reset the trip computer when I set the cruise - otherwise you'll be just altering the stored average mpg (and mph) |

Title: Re: m.p.h Post by hopper on Dec 26th, 2008, 2:56pm Hi, I've had 3 24v Scorpio's 1x BOA Saloon and 2x BOB Ultima Estates, all of them on a motorway run at 70-75mph normally return over 36mpg. The latest on I've just bought 2 weeks ago and drove from Peterborough to Plymouth, it averaged 39mpg on the trip computor for the 320+ mile journey, all Motorways which were very quiet as I left at 10:30pm and arrived at 3am with a stop on the way for a cup of coffee. The car had started with 3/4 of a tank of fuel and still showed 1/4 tank when I parked up at home so about 1/2 a tank of fuel used, 35 litres which would equate to 41.1mpg the trip computor showed 39mpg. Around town the car shows 26mpg. I don't press the accelerator peddle heavily as the 24v has all the torque nessary to accelerate with the meerest press of the accelerator peddle. My 1st 24v The BOA saloon did go as low as 3-5mpg when reading 170mph this was when I was on holiday in Italy. The Italian motorway was still under construction, and near to completion. It was being used by my friends in south Italy to test their cars and motorbikes to the limit before the road was officially opened. I hope to be able to achieve 650miles on a full tank of fuel averaging 40-42mpg. What is the furthest anyone elce has achieved from a full tank of petrol? I know Jeremy Clarkson recently managed to go from London to Edingburgh and back on a tank of petrol in a V8 mercedes and also he drove a Jaguar from France to Blackpool and could have achieved 900miles fromthe tank of petrol, yet Jaguar maintain that a full tank would only return 600miles.

Title: Re: m.p.h Post by Highlander on Dec 26th, 2008, 5:55pm The best I've ever achieved with a 24v was 37 on a trip from Glasgow to Aberdeen but that was with the cruise control set at 55 I average 25mpg usually |

Hmmm I think this rules out my 4 litre engine / high ratio diff theory then, thats the best mpg I've ever heard of for a 24v. Have you removed all the doors, seats and glass?? ;D |

Title: Re: m.p.h Post by Highlander on Dec 28th, 2008, 1:31am Hopper, been having a look at the info you sent me via pm re your 0-60 times, RPM vs MPH etc, and me thinking your 24v possibly being a 4.0 Now your RPM is showing exactly what it should be through the different speeds for a standard 24v 70 MPH 2500 RPM 80 MPH 2850 RPM etc this would suggest the engine is a 2.9 and not a larger capacity otherwise we would expect the RPM to be lower for a set speed. your 0-60 time is around 6 seconds, compared to the standard 24v time of 8.5 secs which is a big difference. similar or slightly better to what it would be when fitting a 4.27 diff to the 24v. Your MPG is head and shoulders above every ones elses at an average of 40MPG compared to the usual max of 35ish for a 24v So somethings wrong somewhere, you cant have great mpg and great performance, it isnt possible. I'm assuming we can take your 0-60 time of 6 seconds as pretty accurate although i assume it was done with a stopwatch or similar and might be slightly out but close enough.. So... the only thing I can conclude is that you do have a 4.27 or similar diff fitted but that the original 24v drive pinion for the Vehicle Speed Sensor is still in place meaning your speedo is reading high.. With the 4.27 diff fitted and allowing for the Scorpios 10% "safety margin" in the speedo the actual speed when the speedo is showing 60 would be around 47MPH This would also explain the exceptional MPG as the fuel computer is reading the correct amount of fuel being used and remaining but being given a milage figure 20-25% above what the car is actually physically doing. This would make your actual MPG on a run around 30 and around town as 20, which is what I see on my 24v with the 4.27 diff when driving carefully. The only way to check without having a look at the diff would be to check the speed against a satnav or against another car. |

Title: Re: m.p.h Post by Jonnycab on Dec 28th, 2008, 3:21am 0-60 in 6 seconds ???....If the car were that quick off the mark, then it certainly wouldn't be so frugal as to do 40mpg+ on a run.....surely :-/ |

Title: Re: m.p.h Post by hopper on Dec 28th, 2008, 11:37am Hi Johnnycab and Highlander, I know that the figures are very confusing I'm going to look further into the trip computor and fill the tank to the brim, run the car a good distance and then full to the limit again thus, distance from mileometer divided by fuel used to top up should be an accurate mpg result. The car feels really quick rather than the speedo misreading the velocity the tyres are 225/50/16 all round so not quite the correct size for speedo, I do run high pressures 32psi front and 35psi rear which will reduce friction and it was a very cold December morning so better compression. It does seem that the cars engine has had some work done but no documented evidence when i purchased the car 2-3 weeks ago. What if it was a 3.7 or 4.0ltr fitted with the 4.27 diff rather than the 3.64 I'll log on to tyresave to use there tyre size calculator to check the difference in rolling diameter that may explain a small part of the discrepencies. If I was not so far down the Country in Plymouth in Devon you could see the car and compare notes. Regards Chris |

Title: Re: m.p.h Post by hopper on Dec 28th, 2008, 12:04pm Hi, According to tyresize calculator the 225/50/16 are 631mm just 4mm longer on the rolling surface the 205/60/15 which are are 627mm this is only a 0.64% difference so should not have effected the speedo readings to much. Maybe its a prototype hybrid that Ford kept quiet, as it was10 ahead of its time and has slipped on to the open market? Hahaha Regards Chris |

Title: Re: m.p.h Post by pinto on Dec 29th, 2008, 6:55pm If it was a BOA cossie, with those figures i'd wonder if you'd been lucky and picked up one of the 24V FBE racing engines that ford "lost" into the production run when the 24v race series never took off. ;) |

Title: Re: m.p.h Post by hopper on Dec 31st, 2008, 8:10am Hi Pinto, Definatetly a BOB plenum etc.. The figures are quite contradictory the speedo v/s mpg etc... I'm having the speedo checked versus another car at 50, 60, 70 & 80 mph to see if there is any discrepency in the speedo readings. I suspect the speedo is ok though as we know what the acceleration should feel like and how the car feels when travelling at 0-60mph and this one seriously kicks you back when you accelerate through the gears and the road speed indicated at 60 mph appears to be genuine but to be sure i'm going to pace the car side by side with another at the same speed and see what both speedo's indicate then post the results. There maybe a fault with the trip computor as it will no longer reset so the only way i can proove the correct mpg is to again fill the tank go for a good staedy run record the mileage then top up again thus distance travelled divided by fuel used to top up ewill give me the correct mpg figure and again i'll post the results, i think this will show an error in my original mpg that was posted earlier. Again i will confirm this as i know that it is very strange to have a car that appears to have abvove average acceleration and returns above average mpg on a run the 2 are incompattable. Regards Chris |
