- I'm 100% with you on the desirability driving of NA engines. But I will say that there is a HUGE different in feel between [modern] supercharged and turbo FI engines. I ran my Z4 M Coupe NA for years, then eventually put an ESS supercharger kit on it and while there is a barely-perceptible change in throttle response the feel of driving it is identical to when it was NA.

My wife's X3 auto, however, is constantly annoying due to it's digital throttle coupled with turbos that need to spool up - only luck allows for smooth light-throttle takeoffs from a stop. Great vehicle otherwise. Awesome, smart AWD system.

it is, but of course the track is 13 miles long. Depending on how you count it there are between 100 and 200 different turns on that track. So picture knowing the track really well but only having two or three practice laps before you have to set a fast time. How do you determine optimal braking points and speed through the Apex for all those turns with such little practice?

I actually think the sport Auto guys do a fantastic job with the limited time they have on the track with a new car. Another way of looking at the Gap in times is that it was less than a second per mile on one of the most challenging tracks in the world in one of the fastest road cars ever made.

YOU NEED MORE HP!

I am lucky that I have the ability to pay for most of these cars (thank God and hard work), but the difficulty in getting allocations for a GT2 RS or Pista are as you describe them. I don't like feeling like some dealer is doing me a favor by taking $300-$400,000 from me and making me buy things that I do not want.

Having said that - they are still very desirable. And they are money in the bank if you are able to get one at something anywhere close to MSRP. Myself - I chose McLaren knowing that they depreciate in value and are not as "desirable" as a special edition Ferrari or GT2. So far, the dealership experience has been quite amazing. I hope it stays that way. Am on my 3rd Mac and am going to be speccing my Senna in the next month or so. That car will hopefully prove to be a good investment.

The ZR-1 is amazing bang for the buck and a great performer. And, just about any of us with $130k burning a hole in our pockets can walk into a Chevy dealer and get one. Flipside is that they are probably dropping in value like most recent corvettes. But so what? Drive and enjoy.

There's no way the ZR1 was within a second of a McLaren Senna... The Senna has more downforce than an ACR in corners and less drag than a ZR1 on the straights. It has the absolute lowest center of gravity, lowest weight, most power, and best brakes of any car in that test. I'm in doubt of the authenticity of these lap times.

Open diff RWD, and Unproven!

[QUOTE=Questar;1597394466]Really? My friend had very poor results from the Goodyear’s on his ZL1-1LE... wore them out so fast on track that he switched to Cup 2’s instead.[/QUOT
Stock Michelin’s are crap track tires. I destroyed my stock Tires within 3 sessions with my stock Grandsport on my first track day with the car. They hate heat and pace.

I have to wonder how 'close' the new Cayman GTR4 NA 4.0 flat 6 is going to be to a modern GT3RS? It's lighter, smaller, easier to buy, about $90K more affordable, and truly mid engine. It's also a LOT closer to my prospective budget!

But without the panache of a 911, well the C8 will probably be a considerably faster car anyways

Stopped out at Laguna Seca this morning and Motor Trend was not there. Maybe later but not today. Still waiting to see what the ZR1 will do there.

I Can't wait too....

By the sounds of all the cracking, that was still an expensive spin.

Looks same as ZR1 pace car in several ways.

What is the story with open diff?

johnglenntwo

Few automakers count grams as neurotically as McLaren does, with the Brits even omitting a limited-slip differential in the interest of containing mass. At 3161 pounds, the McLaren crosses the scales 157 pounds lighter than a dual-clutch Porsche 911 GT3.

I guess Porsche hasn't proven anything on the Nurburgring!? And AWD controlling things there too sub7! And Corvette isnt proving anything either.

Anyway, they need to lay down that Ringtime!

Mclaren uses a brake vectoring system and brake steering system that replicates what a mechanical LSD does. It saves weight, I guess.

johnglenntwo

No CCB's makes more of it less feasible.
That's what The Nurburgring is for!

Simply! Carbon Ceramic Brakes can stand up to all the extra use these modern street car chassis control systems demand (especially the Mclaren!).
It's illegal to drift at The Ring, and as of today this new Mclaren's still playing up its drifting mystic. It probably still doesn't have enough DF, and it looks like it.

Got it. Thanks. You would be surprised how much downforce you can get without a giant wing. The 720S has been doing pretty well on tracks, and it isn't even a track variant. When engineers are given wide latitude and a a healthy price point, they can be creative. The base 570S is not going to put down good lap times. I had one. It is under-tired, lacks downforce, and dances too much under braking. But it will trap at 135 mph and walk alot of cars with more HP in a straight line. Let's see what the engineers have done with the 600LT. I think we will be surprised. I would love to have one in my garage.
