The article isn't correct. 1.6T WRC/RRC engine was tested already two years a go but the development was stopped in summer 2011 (I think). This time they test different R5 engine and if I have good information the first tests happened already some weeks a go.
Mirek: ...and is the 1,6TSI engine inside this test car or did they use 1,8TSI for very first tests?
What 1.6TSI are You talking about? I admit I don't know such engine, I only remember some rumors that there shall be something like that in some future VAG cars but that's all I know. In my opinion R5 engine must be based on 1.8TSI but that's just my guessing.
1.8 TFSI has bore-82,5 and stroke 84,1... With shorter stroke (just under 75) it would be a 1.6. All current (succesful) WRC engines are having a short-stroke too. :)
Very good point ;)
Polo WRC 83 x 73,8 mm
Fiesta WRC 83 x 73,9 mm
DS3 WRC 82 x 75,5 mm
Mini WRC 77 x 85,8 mm - this is production based engine, same numbers shall apply for 208 R5 and DS3 R5
Fiesta R5 79 x 81,4 mm - production 1.6 EcoBoost engine numbers
1.8 TSI with shorter stroke - 82,5 x 74,8 mm - almost same numbers as top WRC engines
On the other hand WRC have higher rpm limit (8500 rpm over 7500 rpm for R5).
Thank you guys, this is the way of discussion I wanted to start ;)
Little bit more correct article about turboFabia tests (in czech, but with translator it is easy to understand) - Autosport
It looks like it is not so easy with translator, so I will summarize the article in very short - First part is about atmospheric S2000 which was most successful at Skoda rally history and talks about start developing 1.6T engine few years ago. After coming Volkswagen into rallysport and due to high expences for RRC cars developing of this engine was stopped. Last part is about actual talks about 1.6T engine. Developing of this car was re-born last year. Team is developing car for R5 class and was done few tests during last months. Because new bodyshell (Fabia new facelift) is not ready, this test were made in old bodyshell. So actual car from tests is not new evolution of actual car, only "laboratory on wheels".Quote:

Hopefully the max cylinder capacity is defined in the R5 homologation regulations otherwise a manufacturer could try to homologate a 3000 cm3 engine and saying to FIA: “But there’s no mention of the cylinder capacity in the regulations.” :D
