Good news for Evans, this is expected to be his last rally using an old Volvo recce car before moving to a Focus RS like his teammate Ogier.

is that a such big difference what recce car you use?Quote:

But also to be probably one of the most popular motorsports series growing; where drivers get more money than everybody else (ok 1 or 2 F1 drivers get more, but not a ggod nuber of drivers), and given the amount of money they invest, it should be respected. They are no longer heavy dinosaurs moving slowly in ovals. They are real race cars nowadays. And I am not a fan of oval racing or american style but I feel I have to respect real engineering and racing.Quote:

Yes, somebody who actually read the article.Quote:

Real engine designers don't talk "horsepower"..That's for children on forums..Quote:

NASCAR motors make more BMEP than those poooftie little girlyboy F1 motors..
That is some kind of technology to make pushrod thing fill cylinders and burn better that beautiful multi-valve pent roof motors...
I have never had any interest in going in ovals, less interest in ass-fault...
But Circle track in general--not just NASCAR, but the whole field of circle track racing is the ONLY racing in America worth a god dame dime.
Because its the only racing with any depth of competition..
Remember that when the discussion swings around to US and Canadian rally, and worse, rally-cross. Its all BS and hype and lies.
"Making the most of the increased technical support from Ford Performance, the Rally Mexico winning Fiesta made its way to Indianapolis in America earlier this month for some aerodynamic research and development at the Blue Oval’s state-of-the-art wind tunnel."

NASCAR engine:
- Top power: 660 kW @ 8 000 min-1 (remember figures are intentionally distorted to work in NASCAR’s favour)
- Engine capacity: 5.85 litres
F1 engine:
- Top power: 500 kW @ 12 500 min-1 (remember figures are intentionally distorted to work in NASCAR’s favour)
- Engine capacity: 1.6 litres
NASCAR calcs:
BMEP = (660x120) / (5.85*8000) = 1.69231 MPa
F1 calcs:
BMEP = (500x120) / (1.6*12500) = 3.0 MPa
On my side of the pond, 3 is bigger than 1.69 and I suspect it is the same in the US of A, but as I mentioned comparing these two types of engines is stupid in itself as one is naturally aspirated while the other is heavily turbocharged.
Also, for comparison purposes and using the official figures, which anybody is free to agree or disagree with, here are the calcs for a current WRC engine:
BMEP = (280x120) / (1.6*6000) = 3.5 MPa
Now, before anybody starts shouting how the current WRC engines are more efficient than the F1 engines, if we use numbers that are closer to reality for the strongest F1 engine (currently believed to be the Mercedes), then the BMEP is probably not less than 4.2 MPa.
Modern open face helmets flatter no one's looks.
what's the major difference between the R5 Katsuta is driving now en the one he crashed in testing??

Go argue with Racecar Engineering and tell them they're all wrong. And that you know because this is your profession..They do seem equally enamored by both F1 and NASCAR, which defies all imagination to me. What team to you work for?Quote:

Ogier speaking today:
"We’ve made good progress since last year and in this sport you don’t achieve anything alone – it’s always a team effort. All the energy we’ve put into developing the car over the past year is really starting to pay off. We saw it already in Mexico with a good step forward on gravel, and so far I think we’ve improved on asphalt too which is very positive for the future."
I guess WRC cars still use the road car engine blocks - compared to a F1 engine system which probably costs as much as if not more than a whole WRC car.
Complexity of current F1 engine system guessed at by this writer who gives the reader options as to whether the Honda F1 engine system used in 2017 either did or did not have spark plugs?
A bit more transparency in F1 might be beneficial for the honda fans(if there are any left)?
F1 is a high miler fuel economy run compared to Nascar?

As Ari Vatanen said about the t16 'the car was starting to fly' & this is where I think Seb is starting to reach with this Fiesta..... which is lump in your throat stuff for West Cumbria.
No, they don't. If I am not mistaken the only WRC car with stock block since the introduction of 1.6T cars in 2011 was Mini and it was proven to be a wrong decision. Others use specific engines built from scratch.Quote:

of course,as bigger main caps for crankshaft,stronger between cylinders to cope with the extra pressure and plenty other things that maybe be small but makes the difference.Quote:

To make power you have to have rooms for intake valve--and to have room for valves you have to have room in the bores...
I think everybody;s engines are now "strart from clean sheet of paper" blocks and I think everybody is at 84mm bore because you can shove in 2 x 34mm intake valves in a bore that size...
Gotta have the valve area for power, so you have to have the bore to get the valve size.

Ogier is showing how good he really is now he's are settled in to the Team and the Fiesta is developed and set-up to his liking.
Don`t overhype him, the championship has more drivers capable of winning than ever (well, atleast 1600cm3 generations of cars:D). Sweden would probably have been Toyota`s party, if not for snow-ploughing
Great driver ofc.
5x Champion and his win against all odds last Season... he needs no hype.
If all had the same road conditions I would bet on Ogier to win in Sweden.
Let's put the tinted sunglasses on.
