Make sure you watch until the end for an amazing result!

Not taking anything away from the Porsche but all I’ve got to say is semi slicks and the right weather clearly make a huge difference. It’d be nice to see them both on comparable tyres at least but preferably the same. An interesting comparison none the less!

Admittedly as much as the Cayman lost the first race due to its tires, it probably won the second due to its tires, but what a glorious machine regardless of the laptime!

Interested to see what the 650s would be like on the same tyres as the Porsche

The helmet Jason is wearing is epic! They should use it in F1.

Most negative comments here did not watch till the end. Kudos to the Fifth Gear team for organizing a later test with better weather.

I missed 5th Gear so much and so happy to see you back. What a great video, I love to see you having so much fun. Here in Canada, late May for a track adventure with my brother and our sons! Keep us the great work. Not very often does the passion filter beyond the screen!

True story, I had a dream last night that Porsche announced the GT4 RS in manual. I guess I'll go back to sleep. Great video again!

So it was slower, but who would not want the chance to own a McLaren. What stunning looking car!

Great video, but you should have mentioned the Porsches tire advantage in the dry like the Macs in the wet. On the same rubber the McLaren will certainly be the faster car based on this test. Two absolutely epic cars though!!

What a great video. If only I could drive like Jason Plato! Amazing to see him drive both cars flat out on the track!! I have owned a 650S and it is an incredible piece of kit. Not many cars today can match it for straight line performance. If only McLaren's were easier to sell on the used car market. I drove the GT4 RS in the Italian mountains late last year and it is sublime. Possibly the perfect sports car!

Would love both of these fantastic cars. Problem with the GT4 RS is that at current used prices it's about £140K more than the 650S!

Thanks Jason - so impressed with your wet driving in the 650s ... I have one (Coupe - it's lighter) and personally I find it truly terrifying in the wet ... especially at Coombe! 🙂

The best 5th Gear episode of all times was the Mclaren 12C vs Ferrari 458 with Tiff Needel and Jason Plato.

I had the privilege of being there that day in the wet and got a ride in the gt4rs, shame it had cup2s on however what a car, the sound alone was incredible for a modern car!.

The scream of the GT4s engine above 7,5k is just glorious

Glad you reran with better weather, but the cars still didn't have matching tires. If you did, I'd bet it would be a dead heat with the 650S on Cup 2s. Regardless, shows how sorted the RS chassis is to overcome such a power deficit.

Great review Jason. I'd like to see a comparison between a Porsche 718 Spyder and a 911 convertible. Cheers from a Canadian fan.

What a superb video, loved every moment 💥

Obviously you need a third race with the 650s on Cup2Rs, then you can see an actual fair fight.

Your passion it's contagious, I just love and respect your neutrality. Love both machine but I keep the Porsche Cayman RS.

Great test in the sense that one is an older supercar with far more power and the other is more modern, more track focused, but less power. Interesting comparison and I'm here for it

What a legend driving with semi slicks in the rain 🌧. Incredible!

I enjoyed that a lot! Almost as much as Jason!

Lovely video keep 'em coming !

That RS sound 🤯

Jason just came straight from a shooting party 😂😂😂

I appreciate you going back during drier conditions. 👌🏾

A Cayman GT4 4.0RS is naturally aspirated, with the 4.0 TFSI turbo engine it will outgun everything!

What a wonderful test, of two different sets of tyres.

That GT4 RS will never go below £200K.

Would like to know what time the McLaren would do in the dry with the same semi-slick tyres as the Porsche?

Put cup 2s on the McLaren and get a lap time in the dry.

Good luck finding a GT4 at list price

GT4RS... naturally aspirated... long may they remain. Possible legend the 4RS.

I will take The Porsche!

Loved this. Although I'm not sure where you can find a GT4RS for £108k? They're over double that, second hand!

Great video! Thanks!

this is crazy. I had a F80 Comp and in rain I lost only 2 sec per round to 720s. In rain around 2 min lap. Tyres make such a big difference. With Cup2:s you can't do much in rain.

Adore my 650s great video !

100% I would have the GT4RS the sound incredible the one i would have. Thank you Jason

GT4RS is just perfection.

I love both, but I’d take the RS any day. If it was a 675LT then that would be a very hard choice.

I understand content deadlines, but please educate this philistine on the simple question of "why couldn't you just change the tyres?"

Great video. 👍. Would love to see a shootout between the Audi 2018 TTRS (mine is available if needed) and the new RS3 8y.

While I love both the cars. Why not make it day 3. And fit both with exact same tire 🛞 in dry conditions. I am willing to bet McLaren wins the lap times. But for me the sound alone on GT4 RS does it. My choice even if it’s slower.

Very exciting to watch.

What a challenge 👍🏼

Using your price quotes the 650 is a steal. I am furious (jealous) at Porsche. I have been trying for almost 2yrs to get a gt4rs. Why can’t I? Because the dealerhips won’t let me since I am not a previous Porsche owner from them. I did find some that will let me get on their 2024 allocation list if I pay $75k USD above sticker. I am so pissed I hate them (because I would love to buy it but it is already a premium priced car before all the mark ups and games).

But what tyres did the McLaren have on the dry lap? Same tyres that were made for the wet? If it's fair to have the correct tyres for the conditions then the McLaren should have had dry weather tyres.

Just shows you tires are more of a performance maker than anything else.

At 11:15… AND THE CROWD GOES WILD!!! The 650S is insane & already done with it’s massive depreciation, so I would get that - but props to the GT4 RS for the win! Great comparo!

Yes is the new shootout coming soon

Would gladly pick that NA Cayman over the McLaren. Plus I like build qualities that at least match a Golf’s, which isnt really the case in a McLaren.

Cmon Jason. £108k for a GT4RS 😂 that might be list but there are just 3 on auto trader all at £235k+

Something has gone wrong on your progressive/interlaced settings guys. Very zig zag and aliased on many shots. Loved the piece though on a tough wet shoot!

If the McLaren had cup 2s on the dry track it would of put those seven seconds it had in the wet track on the Porsche

What if the Mc 650 had cup2 tyres 🤔

I’ll take my 650s all day. Plus the prices quoted are hilarious you can’t get a Gt4rs for list or even close! Plus mclaren depends where ya live in USA a good well optioned one with low miles is >$150k but still less than GT4RS. Plus drop the top on the 650s & it’s an entirely different experience.. both great but I’d still choose my 650s

Plato looking and starting to even sound like Brian Johnstone! Bit faster version of obvs

that was amazing

Porsche. There is no substitute.

Some points felt like Damian Lewis speaking in Billions character.

when a professional racing driver is having this much fun in these cars it just shows that they are not even remotely made for us mortals 🤘😎🤘😂😂😂😂

The ol' geezer has some quick hands, even to this day! Well don Plato :)

Crazy impressive how great the 650 spyder is

What tires did the McLaren have? If it did so well in the wet, I can only imagine they were less hardcore than Cup 2's for dry duty. I really struggle to imagine that the GT4 RS can be as fast on equivalent rubber, even though I worship that Porsche.

Get the Mclaren on the Pilot Cups and I think it would win

It may be addressed as I'm only at the start of the video, however why are these being compared, I'd have thought they're in different price category?

P O R S C H E 💥 Period 😎

Considering the 650 is less than half the money of the 4rs in the current market, what a bargain.

One has double wishbone suspension and a carbon tub, the other has a 4-wheel STRUT suspension and not carbon tubbed

Mclaren ❤

Porche everytime for build quality and reliability!

What tires were on the 650S?

Porsche ❤️

All car reviews from Britain are by law done in the rain.

A 675LT vs GT4 RS would be fairer challenge. Especially as both are similar price on the s/h market

It would be quite fun to see/watch a #Koenigsegg versus a #GordonMurray #T50 #Shootout!!

@8:12 pure skill

The gt4rs is anywhere from $263k-$300k usd… Mac ftw 😂

Nice one Porsche

I always say, tyre's are everything, if the 650 had the same tyre's as the gt4 it would be worth a second. The gt4 thought, it's is a mini hypercar.

If possible please do a Chiron Vs Regera comparison.

No comparative test on any cars can be done if all cars don't have the same tyres. They do that nany times in bike tests. Give them only that on an equal base. I want the GT4RS..

Lotus are bringing out the 133 soon to take on the Porsche Taycan, I wonder how their previous fastest 4-door would do against one though? Lotus Carlton v Porsche Taycan.

As is almost always the case with these flawed yet entertaining Fifth Gear tests, there remains an issue. For the comparisons the be fair, ALWAYS fit the same tyres to both vehicles. Surely that would have been cheaper than spending a second day filming.

This guy is awesome.

Where can you get that Porsche for that price?

I'm ready

When did Jason turn 60

I will admit I never knew RS = Rennsport 😬

You Sir are an absolutely wonderful driver. Yes, I am a devoted Porsche lover, but there is something about the McLaren pedigree that makes it a very special car as well.

good luck getting a GT4 RS for 108k, try 200k.... why reviewers ignore the UK price is for very few "special" customers and is not for the general public.... so price wise the RS is way more expensive, but it is "new" although interior is also years old now... try about 7 - 8 years out of date with the 911 interior

I wouldn't say new tech helped at all. The Porsche is just set up more on the edge. 0.7s on a 2 mile track would easily be made up by putting the same rubber on the McLaren but the McLaren is also going to be able to get much closer to that when its not on a smooth, dry track. Its also going to ride a lot better and be daily usable while the Cayman is rattling your teeth out for that few tenths on a perfect lap. The Cayman is the better hop lap chassis set up but if thats your thing why would you get one over something like a Radical? Great to see two real cars again though. The look-at-me electric nonsense was getting old.

Porsche there are no substitutes!

One car you can drive to the track lap all day and drive home. Fill up the tank and do it again the next. I'll let you guess which car can do this without an issue.

Can't stand it when reviews aren't fair because of tyres. I see them as a consumable/personal preference/situational item. Really need to get the same tyres fitted to both cars to even bother doing any kind of comparison.

The key is when Jason says with the 650s , it is hard to find fault. And there lies the rub. I love performance cars, but McLarens lack character and charisma. The key to this and every Porsche is that they have caveats. THAT is the key. Perfection has to be imperfect. I'd have the Porsche every single time, because of how involving it is, how it makes you feel part of the experience, rather than sitting in something with the name you'd expect on a vacuum cleaner, with the same level of character. Just my opinion.

La McLaren sans hésitation.❤
