WATCH LIVE: First gameplay live on Twitch TV.

Version 1.5 brings some interesting and highly requested new features to the title, not least of which is the new pitstop functionalities allowing fuel and tyre changes as well as damage repair in both single and multiplayer environments. This is big news for racing fans and will no doubt add another layer of immersion to the racing title.

On the physics side of things all cars in game have now been upgraded to bring all vehicles in line and using the latest tyre model introduced recently allowing "more realistic load sensitivity, a variable grip curve after peak, closer performance level between compounds, a brand-new surface and core heating model as well as more realistic heating operation range."

Released alongside this new update is the second free bonus pack to be released for the sim which brings Black Cat County, a new fictional road course as well as 3 new cars in the form of the Corvette C7 Stingray, Ford Mustang and Fiat Abarth 595.

a 400 plus horsepower car should be able to kick out the rear end a 20 mphs in second gear. It was the same way with cobra when it came out. AC still just has soft throttle response.

I don't have trouble with that even on the semislicks. The Mustang's pretty easy to not spin the tires on (well it does weigh like 3800lb) but at the same time if you want it to, it does.

 

[Qazdar Karim]

Innitially it did seem too easy because i was taking the corners at my 1.4 speed, once i went aggressive it revealed itself imo.

And this is exactly what i mean, i don't know what do you think about it , but for me it's not natural ... you need to feel that you are getting closer and closer to the limit, not some kind of sudden loss of all the grip.

 

[Conrad Miller]

Sigh...
Perhaps the tyres were unable to warm up properly in previous models, resulting in less grip and more graining?
I thought this was a known fact. Now they are fixed, and then according to you they are too grippy and aimed for consoles..
You can turn everything in a conspirancy, if you want.

 

[Conrad Miller]

Kunos still can't seem to get the powerband right, the new mustang unless you dump the clutch at redline in first getting it to kick out is impossible. a 400 plus horsepower car should be able to kick out the rear end a 20 mphs in second gear. It was the same way with cobra when it came out. AC still just has soft throttle response.

Why are u suprised? This exactly what console gamers need!

- Pitstop are now available in single player races

How to activate it?

I think you just pull in and the speed goes down, and the lollipop guy is waiting.

I did enjoy it, there's good feedback imo, i can still dance around the line honestly.

In 1.4 there was a lot of people in the forums that thought this margin was too big and you could abuse the cars risk free, now you think it's too small(let me highlight to others who might want in on this discussion that this applies mostly to slick tires), there's no rule on what's perfect.

The good thing is this new tire model seems to offer more options on how you want to control that margin which is what modders like you wanted right?

I literally had about 12 minutes yesterday, I was trying to do practice laps with one car on one track. When I pulled into the pits it is what happened, sorry for misinformation. Look in the download section here, there's an update to a Pitstop app, maybe you will find what you want there.

 

[Ado Pusina]

The cars feel incredible! GT3 GT2...better than previous TM for sure, nice track updates, looking groovy Now, the AI still likes to kill rather than drive...Would be cool if they could just let me through the first curve.

 

[vee10]

They certainly were not built for ‘gentlemen’ racers, although many were gentlemen in that time and before it. But as some said before to get a grips to how challenging they were you need to explore the limits. Unfortunately there aren’t many tracks that resemble how they were in the 70s, but maybe Brands can be a measuring stick. See what times they did and if you can get close or beat them, try to make the conditions the same.


My measuring stick is Monza and the GT3s, I have relevant data from last year and we have a current spec car in the Huracan. At optimum grip I can beat their times they did in practice, just. It’s not easy, the track is all about maximising corner exit, average speed, and minimizing braking distances running with min downforce relying on the mechanical grip. In that sense the tires feel more like tires and not as devoid of grip. They are now more sensitive to your driving, load them too much for too many corners and the core temp goes up and you’re off. PS. Kinda pissed about them making parabolica up to modern vanilla standards with the tarmac runoff, sigh.


Racing by yourself and seeing how tire models change and deeming them “easier” I can see how you might come to the conclusions you did. When you have accurate yard sticks to measure your performance in the game/simulation vs real life counterparts you will see that to a certain degree what AC does is not very far off in most cases.


GT3s are most certainly not boring, if you’re a racer (please take that in the pure sense of the word and what it means ie. Compete for lap time, position etc.) you will see each cars character, its strengths and flaws and its quite nice to have such a variety as we do now. So far so good, but I have a feeling we were here in 1.3…

Excellent post Cristian, it inspired me to get a bit more scientific. Using the 98T and Brands as the benchmarks. Here are the fastest laps from the 1986 GP held at Brands.

Nelson Piquet Williams Honda Qualifying Lap time 1:06.961

Nigel Mansell Williams Honda Fastest Lap in the race time 1:09.593 on lap 69

After a few setup tweaks I tried the 98T on 70% boost Soft tyres, Track optimum ambient 20°C and managed 1.16.381.

On lower fuel and Quali tyres same track conditions in did a 1.13.169. See video below for those laps.

So I am way off the pace but miles faster than previous versions of AC, there is some more time left as I only did about 10 laps total but I can't see me getting 1.06. The fastest on RSR livetiming is a 1.05 I am currently 13th on there with that quali time which would of qualified me 23rd for the real world race behind Johnathon Palmer in a Zakspeed the Lotus bosses would not have been happy! See https://en.wikipedia.org/wiki/1986_British_Grand_Prix for race details. It's amazing to see the massive difference between first and last in those days 6-7 seconds at Brands.

What does this prove, well I am not really sure other than V7 tyres are miles quicker than the previous incarnations and I still don't have the sensation I am in a turbo F1 car although I did enjoy the run a bit more I still felt like I was attempting to master a game rather than a car.

 

[Stereo]

Well you should be qualifying at 100% turbo, that's what it's there for... I think there's also a setup option to move the car's redline higher which will blow up the engine in a few laps, but really 1 is all you need. (run a warmup lap at 50%, then before the last corner turn boost to 100%, and go for it for one lap)

 

[Trezoitao38]

Lazarou, what is your point of the turbo? Because turbo means nothing if you dont specify the point of the problem, I supose you dont have the information about the intercoolers, the turbocompressor, the air intakes, and nothing else about this car. A turbo engine can lag too much or can lag nothing, depends very much how it is made.

What I know is the car was made by Gerard Ducarouge who was very famous as a car designer, so I think make more sense to say that the car is easy to drive than hard to drive. Also, Prost said one time that MP4/4 of 1988 season was a very easy car to drive. That what make some car champions, off course, people like you and me dont have the enough skill to drive these cars fast laps consistently, which is the real challenge of a F1 race.

People think these cars was made to only have most powerful engine possible and this, only this, is sufficient to win a race. Why grip if the pilots are aliens that in a car with the most confortable sit can make fast laps? No, tha car designer dont need to make the car more grip. Also the Goodyear, Pirelli, Bridgestone, Michelin and other are not concerned to make good tyres full of grip. Only the turbo receive the massive technology, not the chassis, not the aerodinamics, not the suspesion or anithing, a F1 car was very similar to a dragster, the only difference is that can make more laps until the engine explodes. You and me knows that this was not true. The reality is that power is nothing without grip. Turbo was important in F1, very. But if the drivers complained about a lack of grip every lap, they didnt have used the turbo engines, nor Niki Lauda come back to F1 to drive a car imprectitable after his accident in 1976. The reason he came back is the Mclaren made a safety car, but also, a very stable car, that he can drive with very confidence, like he made on seventys, with natural aspirated engines.

Looking at your video, if I may suggest, try to keep more on throttle the car mid corner, but most of all try to accelerate earlier at corner exit, this definitely shaves seconds off...and, as Stereo said, use maximum turbo when hotlapping!
The hardest work and biggest fun is in the area you're exploiting a car potential up to the very last second.

You must be in a race as far as I know there is no pit stop in practice or qual. Only during an actual race. During a race a box will appear where you stop within and once you stop the pit stop starts.

The 88 McLaren had just over half the power output of the 98T ofcourse it's easier, and we don't have the same references as Prost on a car difficulty.

But you can't defend the 98T on AC, that thing can corner at 6G, which is not normal for cars from that era.

Just for a reference, 2010 cars were on rails in high speed corners and barely went over 5.5G.

But yes, Im racing in single player mode, driving to pits but mechanics are not waiting for me((

 

[Valentin Neubauer]

did about 10 laps total but I can't see me getting 1.06

as far as i know the track changend over the Years, for example turn 3 was much faster at that time!
please correct me if iam wrong but the 98T felt and feels like on rails

 

[mclarenf1papa]

Don't forget that the brands hatch layout has changed since then....

edit: a bit late...
