Yup, the regs actually 'favour' 2X4 in some respects. (but not in other)

The winning Peugeot was 2X4 and it outperformed the 4X4's almost everywhere.

. . . plus , I think that the restrictor to the engine could slightly be enlarged by going to 4X2. . .
The biggest gain will be the weight drop of 600 kg (?) , improved power to weight ratio, better floatation in the sand and mud, decreased rolling resistance, . . . . etc.

Side note: I saw Giniel de Villiers' Hilux last week. 2x4 (rear wheel drive), bigger tyres and a Lexus V8. I'm not sure if it's the same engine as last year and for some reason they wouldn't let me drive it...  ;)
And Nasser Al-Attiyah is now also driving for Toyota

Is it just me or do the front wheels look wider apart than the rear?

And I still think naturally aspirated is not the way to go, cant compete with the turbo charged cars at those altitudes. Cant understand why you would actually favour the naturally aspirated engine? Its heavier on juice, lower on power and a heavier engine. Maybe reliability? But the turbo charged engines seems to work fine throughout the race, so why o why stick to the V8?  :BangHead: :BangHead:

That's actually a very good point that I forgot about Pom.

Turbo engines are a must for anything over 3000m.

I honestly cant see the reasoning behind the V8.

And do you maybe know why the front wheels are running wider than the rear?

. . . V8 , Toyota branding ? , may be not. Just plain- betroubaarheid persepsie ? (reliability perception)
 . . . wider front wheel track gives potential better stability in a straight line and better potential turning dynamic ability. (Look at most small people cars front wheel track, even some commercial 4X4 bakkies have wider front wheel tracks than the rear eg. Toyota Land Cruiser and Nissan Patrol etc.)
There are negatives to this tracking layout eg, the front and rear wheels do not run in the same spoor (track) so increasing the rolling resistance in snow, mud and in sand. Thus reducing overall potential mobility.
. . . however  . . . Lets have fun and hope that a RSA driver in Toyota RSA "designed and build" wins again.

Wider front track also reduces understeer, or alternatively, narrower rear track increases oversteer, making the vehicle easier to turn, especially at speed and under power.

True, but why not just widen the rear as well? Eliminating the fact that the wheels dont run behind each other.

While racing in a straight line, having wheels in line is inconsequential, especially in offroad racing. In corners the rear wheels are probably never in the front wheel tracks anyway.

Great series of vids - privateer Manuel Lucchese has started a series of GoPro diaries explaining exactly what you need to do enter it and get ready to race it. This is the 2nd on what it really costs to race the Dakar (do not forget to convert to ZAR and add some extra for transport distance etc).  :confused2:

The Toyotas were simply no match for the Mini's or Renaults which where much mush faster. Despite this Geniel managed to keep up in the front of the field. He must be be of the best drivers in the world now.

I remember when Geniel was racing touring cars (I think) and there was an international drivers rating which used some calculation to compare drivers across disciplines / formulas and Geniel was rated the number 1 or 2 race driver in the world  . . . alongside Schumi . . .
