Peugeot 508 2.2HDi GT - talk to me...

Renault Talisman...



Why can't we have it in the UK!

That's a handsome brute.

Day 1: £22,500.00

Day 90: £1,750.00

I was rather surprised when I read the specs for new 508 (attached) how close patrol is to diesel now.

Nice figures.

Going to add petrolprices.com's daily average of 124.4 unleaded and 127.2 diesel (£5.66 and £5.78/gallon)
Taking extra-urban, that's 9.22p per mile for petrol, or 7.98p/mile diesel. 1.24p/mile difference.
At 10,000 miles, that's £124 saving you get for a noisy soot factory that's quite a bit slower.

The "508 First Edition" appears the only model with a petrol engine on peugeot's website today.
Petrol baseline is £36,975. Diesel baseline is £37,400.

So the diesel will start save you a small amount of money after 34,274 miles. If you don't mind the noise or vibrations or smell, and ignore the DPF costs

I'd still argue that in an extra-urban scenario the petrol will not get anywhere near it's figures so the gap is much wider.

And 35k is about my current average yearly mileage.

I'd still argue that in an extra-urban scenario the petrol will not get anywhere near it's figures so the gap is much wider.

Why not? (almost) every petrol car I've had has exceeded the stated extra-urban by some margin on runs:

406 2.0T: Stated 28 mpg iirc, actual 38.4 mpg
406 V6: Stated 37 mpg, actual 46-48 mpg
E39 540i: Stated 32 mpg, actual 38 mpg
Picanto 1.2: Stated 49mpg, actual 56mpg
W218 CLS63: Stated 37 mpg, actual 16 mpg. Damn. Loud pedal is WAY too good...

OTOH I've found diesels very difficult to get close to their stated economy on a run - the hdi90 being the sole exception

How are you getting 46-48 mpg out of a v6 406? I can just about scrape 48-49 out of the 110 GTX and that's driving it like miss daisy is in the back. The best I ever got out of my v6 calibra was 38 mpg on a run down to central France. I always take extra urban figures with a pinch of salt, combined it the better figure to go for. But even then it's only been reached in a controlled conditions way so us basically bullshit.

[piglet]

Won't tell you how it's going with the 3.0tdi

[Welly]

It's all fairly simple if you think about it, I've ran 2 x V6 petrol's in the past and whilst cruising along you have to remember that there's 6 x injectors firing all the time just to keep the car moving along, probably 3 or even 2 cylinders would cope under light loads. This is why Audi have the clever 4 cylinder petrol switching to 2 whenever it can.

Verdict: multi cylinder engines are thirsty!

I went north on the M6 over the weekend. 25 or so miles of 50mph SPECS cameras. Turns out the biturbo can do 36.8mpg at 50mph. I expected a lot more, but I think as with nearly all modern cars (think "Dieselgate") I suspect they either gamed or straight out cheated the test to get the economy figures. Dunno why the AMG lump is so inefficient compared to the BMWs V8, maybe the auto box wasn't in top gear at that speed?

There is no way on earth I could get my car to produce 37mpg doing that if it can't reach it doing 50mph on cruise.

Look at all the things they're allowed to do! https://en.wikipedia.org/wiki/Fuel_econ ... les#Europe

* Disconnect the alternator, thus no energy is used to recharge the battery;
* Use special lubricants that are not used in production cars, in order to reduce friction;
* Turn off all electrical gadgets i.e. Air Con/Radio;
* Adjust brakes or even disconnect them to reduce friction;
* Tape up cracks between body panels and windows to reduce air resistance;
* Remove Wing mirrors.

Bet killing the 180A alternator and the compressor for the 3-zone aircon would be a mahoosive economy boost on mine.

I think in the 90s/early 2000s nobody cared that much about economy figures, so they were just like "yeah throw the car in for a test and we'll just print whatever it scores", so you'd get figures that you could easily beat in real life. Now, those figures are everything when it comes to selling cars, so they're as inflated and unrealistic as they can possibly get. The Germans seems particularly bad for this!

[STALLED]

I'd avoid something with 150k on the clock - even with a FSH.

Always liked the shape of the C5 and can be bought in identical spec with the floaty suspension!
