Mercedes F1 team boss Toto Wolff is impressed by the look of the new cars
Mercedes will unveil their 2017 car on February 23, the day before Ferrari and McLaren do the same.
The regulation changes in F1 over the winter are some of the most radical in decades as the sport's bosses attempt to improve cornering speed and encourage overtaking.
And Wolff, having seen the new model, has admitted that the look is just as impressive as the speed.

“I am most excited to see how the new car’s going to go because we expect them to be much faster and they look spectacular,” Wolff said.
“It’s going to be much more physical for the drivers.
“But when there’s such regulation change it gives opportunities – and risks.
“We have set aggressive targets for where we think the car should be, should be going to, and also the engine.
“We are pushing flat out to achieve those targets, but will those targets be enough, or will other teams come out of the blocks better than we do?
“We don’t know.”
Nico Rosberg drove the 2016 Mercedes to the F1 world title
Mercedes have won three consecutive F1 World Constructors' Championships and will be gunning for a fourth in 2017, albeit without 2016 World Drivers' Champion Nico Rosberg.
The 31-year-old retired five days after sealing his maiden world title and Mercedes have replaced him with Valtteri Bottas from Williams on a one-year contract.
The Finn will drive alongside three-time world champion Lewis Hamilton and while Wolff has the utmost confidence in his personnel, the German revealed the team ethos is one of relentless dissatisfaction.

“Whether there’s a regulation change or not, it’s always the time of the year where we are always sceptical,” Wolff added.
“We always question ourselves whether we have done a good enough job.
“This is very much the mentality in the team.
“It doesn’t make our days more happy, but it’s how we function.”
