Senna [Official] McLaren Senna (P15)

That's a shame, it looks like a nice spec. Glad no one got hurt.

So apparently Salomondrin's Senna caught on fire.

Oh dear. Que ten vlogs about this. Zzzzzzzzzzz

 

[Bucketslash11]

i think mclaren should address this fire issue before it becomes a huge problem

 

[M.N.D]

I rarely watch Salomandrin's videos so I'm not that familiar with him, but I have an impression that he likes Mclaren and doesn't like Ferrari or Porsche that much, but I could be wrong. However, I understood that his Senna was delivered to him recently, so it's fairly new. That's a shame for a new car to catch fire so soon.

I think that the Senna is an endangered species. These cars are wasted faster than they are produced.

I would like to say that this is the standard with these limited production hypercars. They are mostly bought by people who are somehow incapable of handling the power level, and the result is either a damaged car, or worse, a totaled one.

I don't know if it has been posted here, but Car & Driver has published an instrumented test of the Senna. It is possible that it has been posted in the scans section, but since I cannot access it, I'll post the link here and share the test results.

One week old. Bought second hand.

One week old. Bought second hand.

Is it possible that there is a defect in that exact car, or is it a factory defect? I rarely follow these Youtube supercar vloggers, and I don't know if there is another Senna that caught fire prior to this one.

Could be a defect in the car, these super cars do catch fire from time to time.

 

[M.N.D]

Could be a defect in the car, these super cars do catch fire from time to time.

I remember back in 2010 when around 3 or 4 of the then new Ferrari 458 Italia caught fire, and Ferrari faced a backlash from the media.

Speaking of the Senna itself...

After reading the performance figures of Car&Driver test in addition to a number of other reviews, I see the Senna as more of a marketing stunt than a true halo car for the brand. Granted, acceleration figures alone are in no way enough to form a conclusion about its performance, but from the small number of the track tests that took place so far, the performance gap is not that big compared to what supposed to be a "street legal GT racing car".

Upon the release of the car at the beginning of this thread, there were posts from people on instagram whom I assumed that they claim to be close to McLaren stating that how the car will be quicker around a track than a GT3 racing car, and the press release of stating the 800KG of downforce through the extensive aero package with a DRS, coupled with a lighter weight and more power compared to the already fantastic 720S, yet all of this and the P15 didn't stand heads and shoulders over its lesser sister, at least in what it is supposed to excel at, which is gaining a significant lap time advantage. An example I want to refer to is the road holding figure in the test above (1.12 G) which other cars like the ZR1, the GT2 RS, and the 720S can match.

I don't care that much about lap time records of street legal cars, but it is considered a performance measurement, and the hyperbole that surrounded the Senna at the beginning was too much. Not that I was going to buy the car or I'm affected in any sort of way, but just a personal opinion and observation, as I like things to stay realistic.

I must admit that I felt similarly upon the Senna's reveal that it was more a marketing led outcome - especially taking its controversial styling covering ostensibly 720S underpinnings into account. It's not an attractive car by any stretch. I've since grown to appreciate what McLaren have brought to the table - this is a much more focused track-able car which, weirdly enough, looks terrific (and in its element) in a race circuit environment. So, the P15 definitely needs context in order to make a favourable impression.

Regarding the lateral G figure, I am of the impression that modern tyre technology is the main contributor to lateral grip capability on a 300 ft skid pad. I don't think that downforce can play as significant a role on the skid pad as it will do on a full scale circuit where fast sweeps are taken at much higher speeds. So I suppose the P15's performance needs to appraised in context and I admit that I haven't followed how it's fared in timed circuit laps.

I like McLaren road cars (the F1 was my go to choice back when I used to play Need for Speed video games), and I like how they are obsessed with the tiny details and the efforts they do in building their cars. The 720S is a true giant killer and a force to be reckoned with.

I'm not a race car driver, but I'm a fan of motorsports, and I must say that looking at the numbers alone is not the correct way to evaluate the car's performance, but for the Senna and the talk about how it is as fast as legitimate racing cars, I thought that it will be the fastest street legal car around any track, bar none. I have a bit more to discuss below...

Thank you for mentioning this This is a very important aspect that must be addressed whenever performance or lap times are being discussed. I didn't want to talk about this as my post would become too long and boring.

Back to the lap time topic. Here are the numbers that I gathered from fastestlaps.com:

Anglesey GP Circuit:

Senna: 1:31.35
720S: 1:33.65

ِAutocar Dry Handling Circuit:

Senna: 1:03.8
720S: 1:06.1

Autocar Wet Handling Circuit:

Senna: 1:17.7
720S: 1:09.2

NCM Motorsport Park:

Senna: 1:23.34
720S: 1:29.92

I'm not sure about the NCM Motorsport Park results if they were compared directly or not, how the weather was, and whether the tyre compound was the same or different, but there is a significant difference. As for the Anglesey test, the two cars were compared directly, assuming that the tyre compound was similar on both.

However, the talk about the Senna from the beginning, saying that the car will be as fast as any GT3 racing car, was ridiculous to say the least. A very important aspect is the tyres, just like you mentioned. GT3 cars have racing slicks that, in combination with other factors like a competition suspension system, a wider track and body compared to the road car counterpart and a race grade aero package, allow them to pull around 1.7 G, and there is no way that a road tyre, no matter how grippy it is (such as the new Michelin Cup 2 R) will generate the same grip as a racing slick.

One important thing that I learned from watching different races, is that the effectiveness of the aero package is more significant at higher speeds which makes sense as the airfoil produces more lift the faster the fluid flows around it, so it is the mechanical grip that is more important at lower speeds.

In the end, I'm not trying to downgrade the car or anything. I have no solid credit to criticize the efforts of the company, but just like I said, it's a personal observation as I was expecting to see a big gap, but that wasn't the case.

BTW, the post seems a bit cluttered and unorganized. Apologies about that, but I hope you get what I'm trying to say

Quite a lot of Senna's lately on sale, especially in the UK...

I can understand they want to sell it, people thinks it is a kit car designed by the driver itself...

 

[hoffmeister_fan]

It's probably because they want to flip it in hopes of making a profit, especially if the car has near delivery miles. They knew what they were getting into when they placed an order. Any other reasons are secondary/tertiary, especially in that kind of situation.

And, yeah, while I've warmed up to the design a little, I agree, it looks car-kit-like, particularly when side-by-side to the 720S.

MSO silver one for sale.

The car looks surprisingly tasteful in this silver color.
