Toto Wolff has said that while next year's cars will cause lap times to fall by "several seconds", the increased difficulty of the cars will be difficult to see on television.
Next year will see Formula One adopt a radical new aerodynamic approach, with wider wings and a lot more downforce, plus wider tyres.
Speaking in an interview with French paper Le Figaro, Wolff said the improvements made by the cars will be "impressive".
"It's hard to determine the exact gain per lap, but I can tell you it will be several seconds as the data is very impressive," Wolff said. "Cornering speeds will be much higher which means the cars will be more difficult to drive, with an increase in G-forces."
However, the Mercedes boss conceded that the increased challenge for the drivers will be difficult to see to viewers at home.
"It's a pity however that this won't be perceived on TV, you won't be able to feel it. Overtaking may also be more difficult with the air behind the car acting as a factor of instability."
