Thread: GT Class

No GT car has international homologation valid in rallying.

What is a Gt car?

OK, but it was talk about that, to allow them in FIA rallies, or is my teflon brain striking again ?

I have seen Porsche GT3, Nissan 350, and Aston Martin cars. Are there more made ?

Aston Matrin would be useless on gravel and they do not have a place in rally anyway.

Sulland: They are very different cars based on different national regulations.

For example there is huge difference between Porsche of Vallejo in Spain and Porsche of Dobberkau in Germany. The former is complete special made of circuit Porsche Supercup (plastic body panels, special suspension, 470 Hp, carbon brakes, traction control...) and the former is N-GT with normal H gearbox, normal suspension, much heavier etc.

I think they dont differ much from circuit cars because the Aston Fontes uses on the portuguese rally championship is too used on circuit races.

Francis: You are not right. Aston used by Fontes is FIA GT Circuit car with six liter V12 engine, that's right. But Prodrive Aston built as rallycar and used in for example Race of Champions is four liter V8 with group N modifications. It's also made of circuit car but these two are really very different.

What speeds could GT rally cars reach (unlimited)?

Depends on particular gearing. Circuit GT1 Astons around 330 km/h.

What would that be in m.p.h?

Oh sorry I didn't know that, I read it was used on circuit, but i guess i didn't read it carefully .

N-GT was the class I thought it was some discussion allowing, but was it in IRC they talked about this, but was not given green light by FIA ?

But they are reasonably priced, and have a soundpicture that make goosebumps, especially the GT3's so they would make sense, at least for many Gentleman drivers, that does this for fun !

I agree but we can't do anything if FIA says no...

Is there a certain safety issue with these cars nowadays? If you rolled the Aston for example with that roofline? Doesn't seem like much margin but I'm no expert.

I think they add a great bit of variety to fields in national rallies. And also come with a great soundtrack.

Try again maybe, FIA is "new" since the last time...

Better ask that in a seperate thread.

Or, dare to use the internet.

Roughly 200+mph

N-GT porsche road challenge run about 250 km/h or 155 mph. More final speed should make no sence at a rally stage, actually 225 km/h but even better acceleration would be enough.

In Spain, the highest speed I've heard was 214 km/h, achieved by Alberto Monarri with a Ferrari 360 Rallye, but it was in a night rally,and Porsche is a better car, so 220 km/h must be achievable
