Stoffel Vandoorne has only sampled his new McLaren charger in the simulator, but according to the Belgian the car will be 'a lot faster' than in 2016.
Vandoorne's statement echoes everyone's prediction for this season with cars expected to be faster by up to six seconds a lap thanks to the activation of new rules.
"I actually don't know much about it," Vandoorne told Belgian news agency Sporza.
"I have only tested in the simulator, but it is already clear that it will be a lot faster than in previous years.
"The past few years were difficult for McLaren, but the team has also made a lot of progress. Hopefully we can start in two weeks with good testing in Barcelona."
As a consequence of the 2017 cars' extra downforce, mechanical grip and outright speed, drivers have been working hard in the gym.
While the end of the winter period is usually devoted to toning the body and reaching the optimised minimum weight, drivers have actually been putting on pounds this year as a consequence of building muscle mass.
"I have been doing a lot of sports to keep fit, that's the only way because there's no driving," added the 24-year-old McLaren man.
"The changes in the rules mean it will probably be difficult for the drivers. But I don't see it as a problem as I've have had a good preparation. The season can start now for me."
