Does anyone think that now petrol engines are becoming so much more effecient that diesel engined cars will gradually become a lot less popular. As an example our 1.9 diesel Scenic use to average 39mpg but our current car. A 1.6 petrol turbo with 150 bhp manages 39 mpg as well. |

My old pug oil burner gets 57mpg.
The newer smaller turbo engines seem to record great mpg in the tests, but real world it's bollocks. If you're careful, you might get close, but if you get the slightest bit fruity, it'll plummet.
Case in point - 1.3 (I think) ford ecotech focus. Brand new fancy car. Postling along at 40 got me 35mpg. Having a little bit of fun dropped it to 20.
Bugger that!

Nope. I have a 15 year old £200k miles 1.5 tonne MG ZT with a 2 litre BMW diesel engine that gets over 45 mpg.
I'm sure a newer one would be even better.
BHP per tonne is the key, that's prob why, in addition to it being new, your new 1.6 petrol is getting the mileage it does.
To do a fair comparison, you'd need to match 2 new cars with the same weight and bhp, one petrol, one diesel. |

That is actually rubbish
The focus is one litre
Claims over sixty
Driven pathetically slow will achive high fifties
Actual average over 10 000 miles driven normally 38
My derv focus now doing 52 |

Cars maybe, vans and lorries will have to be able to return the top mileage when loaded.
If I could carry a 500ko pallet and still get 50mpg out of a petrol berlingo then maybe but I doubt it.
Diesel engines have a lot more torque per fuel used tan petrol |

The theory is that an engine running on diesel will allways be more efficient than an engine running on petrol
This is a slight misnomer as the efficency calculations are skewed based upon derv actually containing more joules of energy per litre than petrol
However due to emission legislation most derv engines are not permitted to run at optimal efficiency and thus petrol engines may be able to catch up ?

Diesels are finished because of the pollution they create...
Petrols will be back in vogue in another five years... But probably competing with electric by then |

Nop!
I've got a diesel and my next car will be a diesel too. Currently got a mk4 golf, plenty of grunt and returns over 50mpg.
Next car looking at a Mercedes 320clk cdi which produces more torque than it 550AMG petrol counterpart.
Diesel is still the way forward for me   |

My Skoda Octavia 1.6 Tdi do 55-60mpg |

Ever driven a Tesla?
Christ almighty, it's a serious bit of kit - and thats without the ludicrous speed kit (yes, that really is a real optional extra)
Cost £7 to fully charge and gives around 300 miles to the 'tank'.

Diesels will always be popular in cars for economy, petrols still are the performance option but both will eventually be in the minority as the hybrids continue to develop over the next few years... The Mitsubishi Outlander being a perfect example of how popular they're becoming...

Lovely car no doubt but the price tag doesn't make it a realistic choice for most. Unless diesel can get cleaner I think it will be relegated back to just lorries and vans. |

This is exactly what will happen as the commercial vehicles are a long way off yet... Take the BMW i3 for example, won't be long before it replaces the 1 series as the mums choice for school run traffic jams... and the rental finance is being subsidised so you know it's the next "must have" accessory...

What your are seeing now is small petrol engine there going from 4 cylinder to 3 cylinder giving better fuel economy but more manufacturer are going down the hybrid way which you get a lot better economy but a full electric car is still power only due to lack of power charging stations

It's started to happen around my area, car parks in particular seem to have grown the most recently especially in town centres... think its part of the gov programme for eco shite where industry profit but we pay... I could quite easily drive one around in one locally and not worry about where to charge...

if i remmber righty they have to have so many charging station by 2020 eu shit i think but the batter technology is getting better and better the new lithium dry cell batteries used to using at the moment are amazing

Yeah that was a long overdue change that will definitely make a big difference... Saw a docu few years ago where a "shed engineer" made his version go further than any of the big manufacturers...
And we've been using them for years in cordless power tools so proven tech too... quicker to charge as well...

'Kin love a go in one of those Teslas
I needed to get a certain item not allowed to mention on here from Essex. The RFD transfer would have cost £40 so I thought sod it, I'll go and fetch it.
300+ mile round trip in the Clio 1.5 DCi and I did it with four and a half gallons of diesel! It was showing 70.3 mpg at one point. Managed to annoy plenty of people following though lol. |

My 1.9 diesel Alfa GT has been tweeked a little bit (OK, a lot!). Currently running 243bhp (dyno proven) and 410ftlbs of torque at 1,500rpm (again, dyno proven) all of the clever emissions systems have been removed (EGR valve, pre-cat and swirl flaps) and it runs cleaner than when they were in place. Best of all I get 55mpg. Show me a petrol car with that much torque, delivering that kind of fuel economy and I'll buy two of them. |

im guess as you remapped it its like a red arrow when you drop it all that lovely black somke from all that unburt fuel ?? you mite have a slight problem soon when the new emissions laws comei.to force

Had an old discovery tdi that got run into, courtesy car was a 1.2 corsa- couldn't wait to get rid of it, it cost a fortune in petrol cos i had to floor it all the time to make it go.. Disco took it all in its stride and still did around 28mpg. ( much more fun in the snow too ) |

No black smoke at all, even when I boot it. A decent rolling road remap with hybrid turbo, EGR delete and breather mods keep the smoke away. As I said previously it runs cleaner than it did with the emissions gubbins in place and was never fitted with a stupid DPF anyway. The new regs only affect new built cars anyway. |

The only problem is when they look for the dpf and there's a straight pipe but it's not a problem if you know someone lol
With our Brera at a mild-ish 270 bhp there is a significant cloud of smoke when you floor it, but the surge of power when the boost gauge needle smacks the stop is awesome. Shame it is such a heavy car. Also nice to get waves and flashes from other automotive connoisseurs lol. |

The GT was never fitted with one from the factory so its exempt from that part of the MOT.
The Alfa wave is getting rare since the introduction of the Giulietta and MiTo because so many people have them as company cars and don't know the history of the marque or understand how close the fraternity of the owners clubs are. |
