Brakes and shock absorbers are sooner overheated in heavy car. You have to use harder tyres etc. I wouldn't underestimate also the suspension design. Much bigger suspension travel is huge advantage (also between older and newer S2000 cars or older and newer WRC cars).
You're right that new cars will be slower than current WRC but I don't see much wrong with that. The gap will be smaller on very fast roads and bigger on twisty ones like with curent S2000 but more.Stupid is as stupid does. Forrest Gump

I can't imagine how this would go if they fitted in a really big turbo....That would be just pure speed.

I'd like to point out another thing which is racing fuel. I don't see much sense in using expensive high performance fuel and in the same time restrictors for making output lower. Why not to use bigger restrictor and standard fuel which is 5x cheaper?

Andy, Im with you on this point. Perhaps you are with me, in a manner of speaking. I posted this about 5 years ago to deaf ears, but I still think it is a viable solution to the problem that the WRC is facing:

Not to get off topic, but I have been saying for some years now that 4wd has made its point. It has also effectively made the visual aspect for spectators on stage and televison alike antiseptic particularly on tarmac events. Im sure that we can all agree that its faster in most respect as a rallycar performs.
Why not go back to RWD? The need for horsepower would be no more than 350-400 on gravel events, and tarmac would have the crowd pleasing drifts back in full effect. Most rally drivers agree that RWD cars are more fun for all involved anyway. So a limit on engines would be moot point. Perhaps the old marques like BMW, Porsche, and even Mercedes might return to top level rallying. We might even see the occasional Ferrari on tarmac events again. Not to mention lifting the mandate on manufacturers commiting to a full season.
I dunno, maybe I have been watching to many old rally 70s and 80s rally videos.Yeah, americans love rallying too.

To still continue with some issues about the new WRC cars.
The costs:
IMO if a S2000 today costs about 250000 – 300000 euros, taking out the NA2000 engine and putting in a 1.6T engine would not add the cost so much.
The S2000 cars has a sequential gearbox anyway (with no active centre differential) so adding a paddle shift to the gearbox won’t add so much cost (as JFL earlier mentioned).
Restrictor size and boost level:
IMO the restrictor size and boost level should be choose so that the best power would be somewhere between 7000 – 8000 rpm. Then we could have cars with the same sound as the B-group cars had or the A-group cars had somewhere between 1990-1995.
Remembering that the torque come from how much fuel/air mixture can get in to a cylinder per every intake stroke, higher boost level gives more torque (and of course more power) at lower rpm’s but the restrictor will at some point limit the airflow and with a high boost, the limit is reached at lower rpm.
Comparing a 1.6 engine to a 2.0 engine with the same boost level, a 2.0 engine can “inhale” about 25% (2.0/1.6 = 1,25) more air/fuel mixture per every intake stroke and therefore have about 25% higher torque compared to a 1.6 engine at the same rpm.“Don’t eat the yellow snow” Frank Zappa

Maybe the official coverage didnt make the most of the island and the rally and once again it was other creators who came up with some great footage. Tarmac is a contentious surface for some...
