(CNN) -- Sebastian Vettel has dominated Formula One for the past three years and looks set to win a fourth straight drivers' championship -- but that could all change in 2014 when the winds of change are unleashed on the sport.
Vettel's Red Bull has been the standout car, with the German consistently faster than his rivals at Ferrari, Mercedes, Lotus and McLaren.
However, McLaren's sporting director Sam Michael says the introduction of new technical regulations next season means a new order may emerge in the world of F1.
Cars currently use 2.4-liter engines but they will be forced to bring in 1.6-liter turbocharged V6 engines next year, while there are also changes to aerodynamics and energy systems.
"When you get a big rule change the engineering structures are not fast enough to respond, even if you're given two or three years to design cars for 2014," Michael told F1's official website.
"Although we're a world away from where we were 20 years ago in terms of preparation -- ultimately until you get out there and run properly you're not going to have as much reliability as you do on the current cars.
"So do I think it will mix things up? Probably. There'll be different results that wouldn't occur like they do now. It's just another thing that's part of rule changes and it's something that you have to cope with."
Vettel has won seven races so far this season and sits well clear at the top of the drivers' championship, with nearest challenger Fernando Alonso of Ferrari 60 points adrift.
But Michael believes next season could be a far closer affair.
He says the introduction of a new powertrain will give teams early reliability problems, while narrow front wings, a reduction in nose height and prohibiting of exhaust blowing will also cause trouble for mechanics.
"When you have such a big change to the powertrain from a mechanical side, you will build in more margin than what you would have done previously," he added.
"Let's say we hadn't made any changes to the powertrain for next year; what you'd be doing is taking an extremely well-known product and chipping away at marginal gains -- a little bit of weight here, a bit of friction there, maybe a change in packaging.
"That's all gone out of the window for 2014 and you'll be in one of two positions -- either you've pushed it too far and you'll be unreliable, or you'll be too heavy and you'll want to take some weight out of the car.
"Both of those things take time. You won't have got it bang on in all areas of the car, so everyone will be in the same game.
"The slope that you get on when you have such big rule change is very steep compared to normal, so I think the development race -- trying to claw back as much downforce as you can -- will be a significant part of the 2014 season."
