I disagree.
They also traded for a single-clutch transmission for higher mechanical efficiency (look at the spectacular dyno numbers) and light weight of the transmission (110 lbs lighter, according to the chief engineer).
The thing that is truly hurting LFA's lap times are those mediocre performance tires it is wearing. I presented all the data comparison of different types of tires and LFA's tires are not even considered high-grip tires, which even cars like GTR, GT2, GT3 RS etc. have.

Heck they are racing a hybrid now
Porsche clearly has the purity edge making manuals but me thinks they want faster lap times to brag and they will need PDK to accomplish this.
I guess we will see in the new few years.

As an example within Lexus having driven the IS F and IS F-sport at the track the difference in shift times might not seem like much on paper but its staggering at the track. The F-sport is much more relaxed to shift, even with the paddle shifters. On the street most of the time it feels perfectly fine. On the track you notice it is lethargic especially driving the IS-F with its trick tranny back to back.
In regards to tires I hope they specify if a car has semi-slicks, like Pilot Cups for instance compared to a PS2 which is a road tire. I've read reviews where they do note that a car has Cups which have tremendous grip when heated but drive horrid when cold (compared to a car without Cups).

I am not necessarily just talking about R compound tires. I am talking about high-grip tires, which do not necessarily mean R compounds. These non R compound tires still work when they are cold and also reasonably in the wet. However, they have extreme dry grip.
An example of that is the GTR GT Maxx DSST 600 tires, which are far more gripppier than the LFA tires (which is why they are ranked "extreme performance" and not "max performance"), but still they are nott R compound track tires.
If you consider the Potenza family, think RE70 that are comparable high-grip tires that are not R compounds (RE70R are R compounds). Lexus decided to put those on the Nurburgring edition when they should have been on the standard LFA as a minimum.

This is the last episode of Best Motoring since 1984. Officially they released today, it has been cancelled.

There is nothing slow about the LFA's shifts, compared to dual clutch trans. it may not be as fast, but its surely not slow. The 911 is AWD for one, and its gearing is probably just right, but around the ring, it still lost out to the LFA. The scans of the article are on this forum. The SLS AMG was just as fast, and weve already seen that lose to the LFA on AutoZeitung, the very same magazine who did this GTR 911 comparo.

Yep. AutoBild Germany comparo. LFA spanked the PDK Turbo S by 6 seconds around Nurburgring.
Some of the quickest cars around a track have the slowest archaic transmissions of all (6 speed manual).

They definitely were controversial always. However, every video I watched was very entertaining with twists and turns. I will miss not being able to watch Best Motoring anymore.
Only now, if I could buy that last DVD from somewhere.

Something wrong with what I said? I guess you're not getting what I mean, so let me explain it; autozeitung didn't use launch control on the LFA, so the acceleration was slower, if they did use it, it would have been CLOSER! I don't think that's an unreasonable guess. I'm not talking about 0-60, I mean to 200kmh. Gengar pretty much proved that AZ had better 100 to 200kmh acceleration in the LFA than the GTR.

You show 1 instance of a magazine who did this test, and are known to use 1foot roll outs for their acceleration tests. I said the LFA would be closer than the gtr if they used l/c. 3.9 seconds compared to 3.6 is a good deal of time when adding it to the run up to 200kmh. For all we know they might have short shifted it the way Inside Line did. You're making it seem like I said the LFA would match the 911 in acceleration tests.

Granted launch control can help in the case of LFA give consistent results and seems like the Best Motoring video proves LFA atleast outlaunched the GTR, I still don't believe LFA can match the PDK turbo 911 acceleration numbers under any circumstances. Off the line, turbo S is completely a slingshot and it's best 1/4 mile numbers are 10.8 seconds.

458 Italia vs ZR-1 vs NSX-R vs 360 RSD vs 370Z
Here 458 Italia is the 3rd quickest in the time attack. However, it comfortably wins over other cars in the battle.
Gearing on the 458 Italia is stupid short ofcourse, due to the insane 5.3:1 final axle ratio (thanks to 7th gear for overdrive comfort and 9000 rpm redline).
