At present, teams are able to replicate some of the characteristics of the cars that will feature the 1.6-litre V6 turbo-charged powertrains, as the V8-engine era that began in 2006 ends this weekend in Brazil.
One significant difference is the cars will feature torque, which in simple terms means the amount of power available throughout the rev range, and is likely to result in increased wheelspin.
Compared to F1 cars in recent years and up to the present day, the way they drive, handle and feel will be very different.
Although the current simulator models are some way off the car that will hit the track in Australia in mid-March for the opening grand prix of 2014, Button has at least been able to get a representative feel of what to expect.
"No-one knows how the car is going to perform until the first race next year," he said.
"It's going to be tricky because we do have a lot more torque for the engine, and there will be a lot less downforce, so it's going to be very tough to get to grips with it.
"Winter testing is going to be hilarious in Jerez. It's going to be cold, the tyres aren't going to work, the cars probably won't work either.
"When you do get a lap it's just going to feel weird because you are going to be running higher gears - you will be in eighth gear before you get into seventh now. It doesn't make sense.
"It's going to be a very different way of driving, and in a way you will have to forget a lot of what you have learned over the years.
"I'm talking about the driveability of a racing car, engine output and the way you put the power down. It's so, so different.
"I've driven it in the simulator, so I know, and I know why they (McLaren) did not want me to drive in the simulator!
"But it's interesting and there will be a lot to learn for all of us, even the experienced drivers.
"It's exciting, it really is, even if it's in a bad place right now, but by the first race we'll have it sorted."
Button is also expecting a degree of 'wacky races' early on as the drivers learn to understand the machinery beneath them.
"The racing will be very close, there will be a lot more fighting," the Briton added.
"It will be like GP2 (a feeder series to F1), in that it will be so much easier to make a mistake. There will be interesting fights on the circuit.
"You've the best drivers in the world, but when it's that difficult to drive you'll make mistakes."
That is where the 33-year-old will be hoping his experience will be of benefit, in particular when it comes to developing a car, although when it comes to the driving he concedes "it could go either way".
Renowned as a smooth driver, Button remarked: "In terms of the way you apply the throttle and the steering, that could suit me.
"But then for the guys who have raced in F1, you could say we have driven in such a way for so long it will be tricky to try something different.
"The positive is we have all the experience of knowing what we can change with throttle maps, torque maps, all sorts we can play with that maybe the young guys won't understand.
"But what I do know is it's going to be a steep learning curve for all of us."
In the final Friday practice sessions this year, dominated by rain over Interlagos ahead of Sunday's Brazilian Grand Prix, Button was slowest in FP2, albeit when the conditions were at their worst and with times almost irrelevant.
In the first 90-minute run on a damp track, Button was fourth behind Nico Rosberg in his Mercedes, with team-mate Lewis Hamilton almost half a second down, and with Sebastian Vettel third in his Red Bull.
It would appear rain is the only factor that could scupper Vettel's bid to equal a further two records on Sunday as the forecast is gloomy for the weekend.
Vettel can match the 60-year-old mark of nine consecutive victories set by Alberto Ascari, along with Michael Schumacher's 2004 haul of 13 wins in one season.
