F30 318d vs Golf 1.6TDI real world MPG Diffrence

[Nuttah]

Considering changing my f30 318d 140bhp to a 2014 golf 1.6 tdi. Power aside would the golf be much more economical, i do 30k a year of pretty much nothing but round town driving, The amount of motorway miles i do is very small and the 318d averages 46mpg no matter how hard i drive it. What would you expect a golf 1.6 TDI to do in comparison? I don't care what it will do on a run or if you drive it with economy in mind etc like i say the 318d won't drop below 46mpg no matter how hard i drive it whats the lowest the golf should drop to?

Probably not a lot.

Little beats hybrids like the Prius (or Auris) for town driving. Regular braking keeps the battery topped up, creep along in traffic queues without the engine running. There's a reason they're so popular as minicabs.

As above for town driving I'd probably be looking at hybrids of even something all electric.

Also worth bearing in mind the VW warranty will only last 60k miles, so if you're doing 30k per year and keeping the car for 3-years then you'll have a year without cover.

High 50's average on a long run, 60+ easily achievable. Would sit at approximately 45 mpg once warmed up around the town. (1.6 TDI A3. Most economical car I ever owned.)

I have a golf mk6 tdi bluemotion estate. It averages around 48 mpg on motorway runs at 70, but this is with ladders on the roof.

About 550 to a tank but 600 without the ladders. Costs £70 to fill

I can't imagine any situation were the extra costs of a new car are offset by greater economy. Once you are doing say 45mpg, the jump to 65mpg doesn't really save you much money unfortunately.


The only significant saving would come from buying an EV and then getting the tax benefits! (ie 100% right down of the full cost in year one etc)

Absolutely this.

At 30k p/a your fuel costs are (assuming diesel at 115p a litre):
40 mpg £3,920.93

45 mpg £3,485.27

50 mpg £3,136.74

55 mpg £2,851.58

60 mpg £2,613.95

The eternal dilemma of energy saving. Energy is still too cheap.

If I were king for a day, I would collect all required government revenues from energy consumption taxes and let the remainder of the economy do its thing.

Living up to your username here, OP.

I have an F30 330d. It does probably 65% motorway, the rest a mix of town and B road. It always gets a chance to warm up on each journey as my commute is about 40 miles each way. I don't drive it too hard everywhere, but it does go in sport fairly often and Its averaged 42 mpg over 12k, which I'm more than happy with for the performance. Amazing the difference town / motorway makes if that's the mpg your getting around town.

The Golf would have to do 1,000 mpg to make it worth changing cars

Hmm Interesting, doesn't make as much difference as i thought and makes me think i may as well stick with or get something else i actually prefer.

Any chance you or anybody else can work out the difference between 45mpg diesel to 30mpg petrol based on 20k per year (not 30) ( i absolutely suck at maths) Thanks!

Suggest you buy a notebook, a pencil and a calculator. Or open excel.

I have all of those and im still clueless but thanks for your help, you give me faith that there are still good kind helpful people in this world.

Edit Found a website that does it for you

Should save a few people having to go out and buy note books and calc's etc.

It's almost like I built a spreadsheet for exactly this sort of thing a few years back

Assumes 20k p/a and petrol at 108p, diesel at 115p

Petrol £3,273.12
Diesel £2,323.51

Buy a small petrol turbo car if you are doing 'nothing but driving around town'.
