New Scania R Series, had one for a week. :)

 
I've always wondered what the vents are for on the front wings of newer lorries... the ones on yours are just forward of the lorry name and serial number as seen on the side view. They seem to be for some sort of aerodynamic purposes as they don't lead inside the vehicle at all. I cannot see what point they serve, as I can't imagine an articulated lorry requires more downforce!
 
That's a beefy looking truck, id love to have a go of one of them in a carpark without a trailer :)

Cosmetic apperance and , so I'm told, reduced wind noise.

Scania (and others) have had these fitted to trucks for years. :)
 
Why 55mph limit not 60?

And no climate control!

EDIT: Also I didn't know the speed limit for dual carriageways for +7.5t lorries is 50mph. Weird.

I notice the 2nd wheel back on the truck cab is also turning in one of the pictures? First picture of the 2nd lot.

Also something i never quite understand, why is there only 1 wheel then a pair , i assume the pair are the driven wheels, in relation to the bit above what purpose does the single wheel do?

Can't see the pics but I think the wheel you mean is the one on the load axle. I'm fairly certain it is raised when running unladen (either without a trailer or with an empty one) to save wear and rolling resistance and lowered when laden to make sure the truck meets the appropriate axle weight requirements.

I'm sure I'll be corrected if I'm wrong though lol
