Peugeot 207 Economique

Found this today:
Peugeot 207 Economique.



Yet another model with a greener version, right?
Quote:
To ensure all the engine’s power is used to propel the car forward, Peugeot’s engineers have spent a lot of their time improving the aerodynamics of the 207. As a result of their work, the 207 Economique has an exceptional drag coefficient of only 0.274, compared to the standard 207 HDi 90 hatchback of 0.30.

This has been achieved by:

Lowering the ride height by 5 mm
The fitment of a special flexible lower bumper trim and deeper side extensions
Optimisation of the vehicle’s air intakes
The addition of an under-tray covering either side of the exhaust system and the fuel tank
The fitment of special aerodynamic wheel trims
The introduction of a two-part rear spoiler with side extensions which wrap around the rear windscreen
To reduce the rolling resistance, Michelin 15” 185/65R15 VLRR (Very low rolling resistance) tires are fitted.
What's new in this car is rear spoiler, which isn't the usual stick-out-in-the-airstream wing, but Kammback flavoured roof and side extension.



This isn't something you see on production cars. Too bad it doesn't come standard on other versions of this model. Also, the rear wheelwells look mighty tall to me, there should be miniskirts covering the top of the tire.

Thats a sweet looking kammback. Interesting bit in the middle with the brake light. I suppose it was much easier to not make a whole new brake light on the kamm extension. Making it easily fitted to all other 207's.
It's funny they didn't touch the wheel arches. Either they didn't like the way they looked with skirts on (and hence lose sales) or the skirts made little or no difference to drag.
This reminds me, i need to post my pics of the 308 i drove.

I love the black side extensions on the rear window. You can see that they are doing "inch-by-inch" changes. The side extension must have been the maximum they could do without sacrificing rear visibility.

It looks like all the new "eco" models (i.e. Hyundai) have lowering on the list. I think I wll look into this for my car.

I know I can get Eibach lowering springs for something under $250. That will give me 1.3" front/1.0" rear lowering ( 33.02 mm front / 25.4 mm rear). Next time I get an oil change, I'll get a quote on installing new springs. I think I will also need an alignment.

Besides the cost, I was worried that my one-size-up-from-stock tires would rub. But I think I would be fine.

When changing my tires this spring I asked the how much it would cost to lower about 10mm. It's about the equivanent of US$350. Now, I'll have to subtract the cost of a normal suspension job and when the time comes ... it'll still be alot Plus the car is already hard (not all French cars are as soft as the legends state, especially sw's), I've had a few complaints from passengers ("Oh no, my tires aren't overinflated - it's the suspension ").

rear sides

Sometimes the glass back there is blacked out around it's periphery and is already a blind-spot for rear vision.To go ahead and fill this in with a foil which does not aggravate vision any further is clever and elegant engineering.No losses,only gains!

I was at the local Pug dealer the other day for some random parts and while waiting I had a look at a 207 on display. The window sticker had a comparison of the model with different engines and I noticed that there is a 99g (CO2/km) version, but... Most "eco" models sacrifice performance for fuel consumption, but here I saw that the 99g not only had much lower FC than the non-99g version (3.8l/100km, 62mpg vs. 4.2l/100km, 56mpg) but also had better acceleration (0-100km/h in 11.7s instead of ~12.5s) and top speed (185km/h vs 180km/h), iirc, even though the 99g isn't noticibly lighter. So I got to searching...

After much digging I found that:
  • The 99g is actually the production version of the Economique,
  • It has a 68kW (92PS) 1.6HDi turbodiesel with a 5-speed manual gearbox,
  • Its urban/extraurban/average fuel consumption in the euro cycle is 4.6/3.3/3.8 l/100km (51/71/62 mpg),
  • It does not have an engine start/stop system, which is standard on PSA's 1.6 e-HDi turbodiesel.

According to this review they did touch the wheel arches:
Quote:
The bodywork also receives treatment to make it more aerodynamic, including a lower front bumper, a flat undertray, side sill extensions and a large rear spoiler. There are also specially designed wheel trims and low-rolling-resistance tyres. All this helps to reduce the drag coefficient from 0.30 to 0.27 - which helps in the quest to use less fuel.
What raised my eyebrows in that review was the following:
Quote:
The 207 Economique is based on the standard 1.6 HDi model, but its engine management software has been tweaked to provide better economy, and it has longer gearing to keep the revs as low as possible.
So maybe I can remap my ECU to get better FE sacrificing some power? I doubt Peugeot will do it, though...

Quite a treat, this car. And there are already a few of these on the roads in Europe, so used 99g's should be showing up soon in the classifieds. Extend the kammback just a bit, cover that gaping grille, add a kill switch, and the car would be sipping even less fuel

I'd say they reworked the wheel caps.

Volvo did exactly the same with their Drive models.

Rica have an E-power re-map for the Volvo 1.6 HDi reincarnations.
It might be worth asking if they could apply it to your Peugeot as well.
