Despite fears that this year's Championship could be decided on the pit wall, Kevin Magnussen believes the new rules place more emphasis on the driver's ability.
This year marks the start of the new 1.6-litre V6 era while ERS and fuel limits are also changing the face of Formula One.
Added to that, this year's cars have less downforce due to aerodynamic changes and a new rule governing the placement of the exhaust outlet.
Magnussen, who is on his way to Melbourne for the season-opening grand prix, spent six days during pre-season testing familiarising himself with the 2014 rules.
And the McLaren rookie, who won last year's Formula Renault 3.5 Championship, is happy to say the new rules have put more emphasis on the drivers.
"It really is a driver's car - more than the old ones," Magnussen told Autosport.
"With the blown diffuser [on the 2013 cars] it became a little bit easy, but this year it's more of a driver's car and I think that's great.
"It's a bit more difficult with more torque. It's difficult to take care of the tyres and I think it's going to be tricky. You need more skill and more sensitivity in your throttle.
"It's still going to be impossible to win in a car that's not able to win, but it's Formula 1; it's man and machine, and I hope we will see the drivers making more of a difference."
Meanwhile, Williams driver Valtteri Bottas also feels this year's car are more "tricky" to drive than last year's machines.
"With a bit more power compared to the downforce and grip you have they are a bit more tricky, and also I think in the race distance it's not only the tyres it's also the fuel you have to save efficiently," he said.
"All these things put together I do agree [it is more driver-dependent].
"From the driver's point of view, saving fuel without losing too much lap time will be very important this year. It's not only going to be the tyres to manage.
"Of course we have some computers to help us, but it in the end it's up to the driver to save the fuel without losing the lap time."
