The higher thickness the more rigid... (Why do I suddenly feel like the heavier the better???
)(Of course, heavier cars are not always better. Similarly, lighter cars are not always better, either. What we need is a good balance of performance and rigidity!!!

(1, 2, 3 are facts, not guesses!!!)1. LC500 is more rigid than GSF by 50%.
2. GSF is 10% more rigid than regular GS.
3. The new R8 is 40% more rigid than the old R8.
4. LC500 is more rigid than LFA by 5-10%. (Lexus claims LC500 is more rigid but didn't say how much)
5. LFA is more rigid than new R8 by 20-30% (LFA's main tub is almost completely built by carbon fiber but R8's main tub is at least 50% built by aluminum!!!)
6. RCF is more rigid than GSF by 10-20% (RCF is significantly smaller but weights almost as heavy as GSF!!!)
So, the result is... RCF could be as rigid as the new R8!!!
(If this is ture, then my GSF could be 20% more rigid than the old R8 but 20% softer than the new R8!!!
In addition, regular GS could be slightly more rigid than the old R8!!!)PS: I also expect R8 should be more rigid than many Porsches, as R8 is an entry-level supercar but Porsche isn't, except some very expensive Porsches!!!

Let's do it again but more conservatively...
1. LC500 is more rigid than GSF by 50%.
2. GSF is 10% more rigid than regular GS.
3. The new R8 is 40% more rigid than the old R8.
4. LC500 is more rigid than LFA by 5-10%.
5. LFA is as rigid as new R8 <<<< I change this, as LFA is an older car built by some older technologies.
6. RCF is more rigid than GSF by 10-20% (RCF is significantly smaller but weights almost as heavy as GSF!!!)
So, the result is...
GSF is as rigid as the old R8. RCF could be 20% more rigid than the old R8 but 20% softer than the new R8!!! (These seems to be more realistic!!!
)PS: Actually I don't think the new R8 will be as rigid as LFA, even though LFA is an older car. But, I believe LC500 is more rigid than LFA... Why? Please check out LC500's hefty weight!!!

(The new R8 could be really as rigid as LFA... I read some information from a web site which mentioned both the new R8 and LFA were about 40,000 Nm/deg in torsional rigidity!!! Auto technology could change a bit faster than we thought!!!
)Let's do it again...
1. LC500 is more rigid than GSF by 50%.
2. GSF is 10% more rigid than regular GS.
3. The new R8 is 40% more rigid than the old R8.
4. LC500 is more rigid than LFA by 10-20%. <<<< I change this, thanks to newer technologies.
5. LFA is as rigid as new R8 <<<< I change this, as LFA is an older car built by some older technologies.
6. RCF is more rigid than GSF by 10-20% (RCF is significantly smaller but weights almost as heavy as GSF!!!)
So, the result is...
GSF could be 10% more rigid than the old R8 but RCF could be just 10% softer than the new R8!!!
Wow! Lexus GS sedans introduced in 2013 was as rigid as an entry-level supercar, R8!!! That's why it's so successfully in 2013, just like Infiniti M sedans introduced in 2005...

PS: I think that could be why a new R8 was introduced in 2015 and a new Panamera was introduced in 2016, due to THE NEW KIDS on the block!!!

I asked ChatGPT "Is LC500 more rigid than LFA?"
The below is the answer...------------------------------------
The Lexus LFA and the Lexus LC500 are both high-performance sports cars that are designed to offer exceptional handling and driving dynamics. While both cars are engineered to be rigid and responsive, there are some differences in their construction and design that may affect their overall rigidity.
The Lexus LFA features a unique carbon fiber reinforced polymer (CFRP) monocoque chassis, which is designed to provide exceptional rigidity and stiffness while keeping weight to a minimum. The use of CFRP allows for a highly rigid and lightweight structure that is extremely strong and durable.
The Lexus LC500, on the other hand, features a multi-material body structure that uses high-strength steel, aluminum, and carbon fiber reinforced plastic to provide a balance of strength, rigidity, and weight savings. The LC500 also features a new rear-wheel-drive platform that is designed to provide exceptional handling and stability.
Overall, it's difficult to say which car is more rigid without specific testing and comparison, as the rigidity of a car depends on many factors, such as the materials used, the design of the chassis, and the suspension system. However, given that the LFA has a unique carbon fiber monocoque chassis that is specifically designed to be extremely rigid, it's likely that the LFA is more rigid than the LC500.
