So this is kinda like the NFL with any team able to win on any given day...with these cars given their extreme performance abilities any of these cars can be faster than the other on any given day.

GrantG

It seems those race cars have more generously proportioned body work for this purpose...

Yippiekiaye

Yup. The 720 he drove was my buddy’s car. Tires were shot on that one.

Whoopsy

Actually the reverse would happens if we swap pro drivers for amateurs.

The McLaren's advantage is straight line speed, it will simply accelerate harder with the extra HP and torque and lighter car.

Porsche's advantage is braking and around corners.

But that's also the difference between a pro and a amateur. Any monkey can make a car go really fast on a straight line, but pros can go around corner much faster, and probe the limits of the car, average amateur don't corner hard enough to show the cornering advantage of the Porsche, they will ended up driving around a corner about the same speed in both cars.

the real question is:
which car draws a bigger crowd at Cars & Coffee?

Howydo

Hopefully, that’s not why you buy a car. With that said my RS is rarer than most Mclaren’s and seems to draw a lot of attention with those who know what it is.

Tires aren’t everything guys. If they were we could put cup 2 R on a minivan and make it faster than most cars. Mclaren’s are great performers no doubt but the negatives of ownership greatly outweigh the advantages.

I've seen your postings with Mac experience... I'll post this again. This is from NHTSA.Gov website when it talks about recalls/manufacture communications/customer complaints.

You get the idea?

isv

But that's my point. Flared arches would allow Mclaren to run a wider front if they chose. It's not a limitation of the tub as is usually claimed. porsche have been doing the same to increase front track width on the GT cars for years after all.

GrantG

OK, makes sense. I guess they could add flares if they chose to do that (maybe they will at some point, but if not in LT then where?)...

isv

I don't know. Perhaps they reckon the cars are quick enough (which would be entirely correct) without needing to compromise road manners further. Ok it's not exactly a like for like comparison but just look at the latest Schmee video. The Senna even with 245 fronts has obliterated the Manthey 2rs with Cup2 R's time at Spa. And that was with a customer car not a factory one.

GrantG

Correct, not like for like. 3x the price should be faster... I wonder how the new hybrid 1,000ps Ferrari will compare (it's rumored to be half the price of the Senna, but not as light and track focused).

Ducati1199

It's normal to express a negative, personal experience but the current crop of Mac Sport and Super series cars do not have inherent reliability issues. MacSF held a track day in May at Sonoma and again at Laguna Seca in June with 35+ Macs both days and no issues.

Howydo

You can show us all the reported problems for Mclaren too. It’ll surely be more extensive. I can tell you from my experience that Porsche in general is much more reliable than Mclaren. If you don’t agree that’s ok as I could care less. Go to any track event and ask any serious driver and most will concur.

isv

It's probably not 3x after the price of all the Manthey bits 😂. But anyway I don't necessarily agree a more expensive car means it has to be faster.

yesyoucan

We missed you out there. I thought you would've showed up for sure -
