Juzh remember that this year the beam wing is gone and the rear wing is mandated to be shallower than previously. That is a sizeable downforce reduction over last year. Not to mention previous years exhaust sealed diffuser setup reduced power by a noticeable amount. Enough that when Williams removed it, they got back a fair bit of straight line speed.

5.3.4 All elements of the power unit specified in the relevant column of the table in Appendix 2 of these regulations must be installed in the union of the volumes that exist between two vertical planes normal to the car centre line separated by 700mm and in a box 150mm long, 250mm wide and 800mm high which lies symmetrically about the car centre line immediately ahead of the front vertical plane.

5.3.5 Power unit mountings may only comprise six M12 studs for connection to the survival cell and six M12 studs for connection to the transmission. All studs must be used and may be fitted on the survival cell, power unit or transmission. The installed end of the studs must be M12 and the free end may be a different diameter.
The mounting faces of the studs for connection to the survival cell must lie on the forward of the two planes described in Article 5.3.4 and be located at Y215/Z15(2), Y340/Z260(2) and Y175/Z420(2).
The mounting faces of the studs for connection to the transmission must lie on one vertical plane normal to the car centre line and be located at Y100/Z15(2), Y150/Z140(2) and Y255/Z345(2).
A tolerance of +/- 0.2mm will be permitted on all of the above dimensions, all dimensions refer to the centre of the studs.
The distance between the two planes is fixed at 480mm (+/-0.2mm).
Any part which provides an additional load path from the survival cell to the gearbox, with a connection to the power unit, may only do so if this is incidental to its principal purpose.

I'd guess merc is probably pushing 850 to the ground, maybe a bit less.

Louts claims that the Mercedes engine has 85 hp more than the Renault, is smaller physical and is 18 kg lighter . http://www.auto-motor-und-sport.de/form ... 72712.html

You can get an idea of the dimensions, if you compare this picture

and the following parts of the regulations on the mounting studs of the engine. Y is the vertical dimension and Z the lateral one, if i follow page 82 of the regulations. Normally Y would be the lateral and Z the vertical dimension.

Yes, it is. But it can only be a single stage turbine.

Same with the compressor.
