I think there can be BoP between P1-non hybrid and DPI. There was a couple seconds a lap between then at Sebring. Granted the DPI's are FAR more reliable over the length of an endurance race.

always been favorable to a dpi-like class; also because, is that different private lmp1 class by now?
dpi's are lmp2 based prototypes powered mainly by street/gt3 engine; the best private lmp1's, smp and rebellion are lmp2 based prototypes powerd by bespoke engines.... that's it.

In my opinion the class should never have moved to a from the street car look.

Maybe I'm just silly but I just love pure prototypes like they are now with massive downforce.

How i'd make ppl interested is rather simple. Introduce cost capping like in lmp2. In fact I'd even BOP the entire engine's to the gibson V8 found in the lmp2 cars. A great car could be built within the exact ruleset as lmp2 minus the engine solution.

That way we'd have freedom in chassis with performance balanced engine solutions. Hybrid is an option but this gives a weight penalty, more weight for more hp output of the hybrid.

Knowing what the Ginetta lmp1 costs am I unreasonable to think that a must sell for a rolling chassis minus engine/hybrid can be around 2 mln euro's is possible. So privateers could even buy factory designed chassis for the same cost cap as others.

Hell dpi even fits within this hah.

Only the (Oreca) Rebellion is 'based' on an lmp2. The others are bespoke to the class.

And even then, the 07 took onboard a lot of learnings from the R-One. So if we're tracing roots back, it's only fair to say the LMP2 that the R13 is based off also started as an LMP1.

Just because a car has the same or a very similar chassis doesn't make them the same in the end. The difference between the Oreca LMP2 and the R13 is huge.

That may be, but the R-One/05/07/R13 do share the same basic tub design. A lot of the differences is that the aero regs in LMP1 are a lot freer than in LMP2. Also, LMP1 privateers can develop things on that end pretty much to their heart's content. LMP2 is basically frozen without ACO approval for changes.

BR1 is based on the dallara lmp2, actually can't be considered a fresh new design at all.

Following your statement, you should consider mazda dpi a bespoke prototype too since is based on a revised multimatic chassis.

agree, chassis sometimes is a vague word.
To be more specific, 07 and R13 carbon monocoque is basically the same; speaking about oreca.

Of course R13 has a better and enhanced aero.

From what I can tell, the BR1 is very different under the skin from the Dallara P217. They share some aero concepts as far as bodywork goes, but the BR1's front crash structure is very different from the P217/Cadillac DPI, and the tub also appears to be different and distinct.

Racecar Engineering weighs in on the LMP1 rules debacle. This article says just get rid of the rule mandating that factory teams have to run hybrids:
