I don't have a link, but i think it was mentioned already like half a year ago?Quote:

"DirtFish understands the one-liter engine option from Toyota wasn’t capable of challenging the 210bhp required for a frontrunning Rally3 machine, hence the shift to a 1.6 motor."
But are there any drawbacks in having a 3 cylinder engine?
fewer valves,Quote:

Also less length of engine.
One difference
Maximum valve lift :
• 11 mm for a 4-cylinder engine
• 13 mm for a 3-cylinder engine
The cam lift must be homologated in VRa2.
The number and diameter of the bearings must be retained.
‘’VVT’’ and “VALVETRONIC” etc. type systems are authorised if original. They may be rendered inoperative.
Check article 261 to see if you can spot other differences:

Also generally speaking a engine with more displacement per cylinder is more suitable to regulations with a small restrictor right?
Imho i dont see any advantage.If you could explain will be usefull.Quote:

Well as an example, 1000cm^3 two cylinder motorcycle engines tend to produce more torque earlier in the rev range than 1000cm^3 four cylinder. Given the restrictor formula "forces" engines to be "low reving engines with lots of torque down low" there is a similarity in the power delivery i'd say, if the displacement per cylinder really does make a difference under current rules is another matter.Quote:

Or... they had to use it for homologation purposes...Quote:

From the videos i saw Gryazin looked pretty comfortable with the car already despite just one day testing. Results here:

Loubet's Fiesta Rally2 is Chassis #8... an early car that has been in private hands in Belgium and I believe not the latest spec.
yes i see snow tyres hereQuote:

If MSport have pinpointed and corrected the issues their Rally2 Fiesta has on gravel/snow in the last joker, then sales will jump very quickly.
I hope they have fixed it, we need all Rally2 cars to be competitive!
It needs more than a joker can fixQuote:

Hermann Neubauer switches from Fiesta to Fabia Rally2 RS from Kresta Racing at least for Jänner Rallye.
Andrien Formaux will stay in Fiesta Rally2 and compete in Janner Rallye too:

M-Sport needs some top results in the Fiesta Rally2 to convince any potential buyers. Sadly even if the car is substantially developed it has a tough fight on its hands vs the existing competition, never mind the new Fabis RS...
M-Sport was promising development, but did almost nothing. There is no progress...Quote:

Are you sure about RS?
The car is worst then the others, don t blame the drivers...Quote:

You’d think they would take it seriously as it’s an important source of income for them.
