SuperGT cars and chassis

Mopar · 10 Dec 2009, 17:23 (Ref:2597372)

Maybe one for the Samuri

But with all the talk of DTM tie ins and the pictures from the Nismo festival, Do SuperGT cars retain anything from their road going cousins? I was always under the impression that the Main monocoque/passenger compartment of the car was to remain the same, however in front of the this and behind were free for modification??!!?!? Now looking at this photo, it appears the chassis is totally space framed? Is this correct?

Tube frame front/rear clips tie into the roll cage that's built into the unitbody.

But I did read somewhere on this site that the current cars are allowed to use carbon monocoques like DTM cars.

In S-GT, if A-pillar and roof of the base vehicle are maintained, it is possible to make it to the full carbon monocoque.
The carbon monocoque of S-GT has the shape of the bathtub, so the roof is supported with roll cage.
Front and rear of the monocoque are tubular frames since 2003.
The transaxle layout of the gearbox is admitted. Suspension design is free.

i´ve been searching everywhere and come up with nothing

Up until the end of 2008.

Awesome car, I love it, but I think we have to call Super GT a prototype series now!

Look at the engine, it wouldn't look out of place in a LMP1.

Actually, comparing pics from samurai's link and this one:

I am sure they are the same block, at least.

I thought I read in an article (endurance info?) that it is indeed the the HPD/Acura LMP2 engine. I could as well have dreamed that though.

NSX used a stock block 3.4 V6, the HSV has the Acura LMP2 3.4 V8.

It has a derivative of the same basic design. The motor is also related to the current Formula Nippon 3.4 litre V8, but with a lower rev-limit. They all (Super GT, Formula Nippon and LMP2) are based on the 3.5 litre design the IRL rejected as a next generation motor in 2006 (for being too high-tech)...
