Great vid, thanks

I like how the car is 2 seconds slower than a 2012 Corvette Z06 (With Z07 package), tells you how much things changed !!!

Of course it doesn't make the car less amazing

No it makes it even more amazing.
40 odd years later, I'd say one of history's more amazing cars and the style of the thing !

Thanks for posting the link, ville31.

Cheers

Difference is too I'd think, the 917 takes driving skill and the 'Vette has stability control and electronics to make up for it.

Not the Z06, it only has ABS, nothing more

It's all in the chassis, suspension, brakes and tyres

I find this fascinating, but what's important is not really the speed at the track, but how the car makes you feel (Hence why the MX-5 is such a great car)

I suspect that's more down to driver skill or how hard he was trying. The 917 beats the Z07 on every count. Hard to believe its actually slower

Weight

917 - 800 kg
Z07 - 1400 kg

Power

917 - 600-630 PS
Z07 - 512 PS

Wheel width

917 - 12" front 17" rear
Z07 - 10" front 12" rear

It's stated that it's the pre-71 (70 actually) category, meaning that the car has threaded tyres

Also, 60's/70's chassis/suspension technologies, don't forget that ! People don't realize how heavily it impacts the performance of a car.

The later versions with slicks would be much faster, but this one is not that much faster than the Z07, if we suppose it's driven has hard as possible

The Corvette is also running treaded tyres. Production suspension has come on a long way since 1970 - but the 917 was a prototype. No compromises for cost or packaging and no rubber bushing.

Chevrolet claim "more than 1.1g" cornering for the Z07, but Porsche were getting more than 1.2g in 1969.

By treaded tyres I obviously meant 60's treaded tyres... Ok right, stop going crazy about my statement guys ffs, I was just pointing out the "progress" in performance of cars since the late 60's...
