DTM vs Aust. V8 supercars?

[gareth_oau]

out of curiousity, how might the two compare?

the DTMs have a 4L V8, limited to 470hp.

I wondered how their lap time might compare on a shorter twisty track, and say something like a bathurst?

Weight is probably equally important...and aero regs

At bathurst, naturally the v8's are setup for that track.. i think they would run rings around the DTM at a track like that...

However lower speed, twisties... DTM would mash them me thinks...

I dunno, its kind of like comparing a MX5 with sway bars etc set up for motorkhanas - short and twisty... against a hsv or a SS that is setup for top speed flat out long straight kind of racing i think...

The only parts the V8s would have an advantage is on conrod straight and mountain straight.
DTMs have far more aero which would humiliate V8s up top.

Erm, pretty sure thats what i said.

Turn out something like that? And that's the "little" rotary.

bathurst has fast corners not low speed. Aero counts more.

I would be willing to also say with a 150hp defecit the DTM car will outlap a V8 Supercar.

i agree...lower horse power but also a lighter shell and better aero. i recon a DTM would be to least 10 secs faster that V8 supercar.

10seconds at bathurst is a tall order, the DTM cars are much lighter and have far better aero. At a track like bathurst I would expect a DTM to be doing similar times to the Supertaxi's but on a track like Oran Park the DTM would walk all over them.

Power makes you faster down the straights,
Less weight makes you faster everywhere,

Bathurst is a fairly complex corning track IMO yes it has a couple of drag strips but anything thats quick across the top will have a serious advantage.
