Carlos Sainz Jr. and Max Verstappen, the Toro Rosso rookies, were among the stars of the 2015 Formula One season.
Despite their lack of experience, the youngsters seamlessly adjusted to the demands of the pinnacle of motorsport to emerge as the most exciting talents to graduate from Red Bull's junior-driver scheme since Sebastian Vettel, now a four-time world champion.
But Sainz fears the team didn't fully utilise their drivers' potential last season and has urged the Toro Rosso pit wall to let them race without team orders in 2016. As Sainz and Verstappen continued their development, the development of Ferrari's new car appeared to stall in 2015.
Although the Prancing Horse have aspirations of challenging two-time world champions Mercedes this year, Ferrari chairman Sergio Marchionne has revealed the team delayed work on their 2016 car to extract the most from last year's chassis.
Marchionne, though, is confident the delay will have no noticeable effect on their competitiveness.
If Kimi Raikkonen again struggles to match Ferrari team-mate Vettel in the upcoming season, Marchionne may be forced to search for a new driver for 2017.
And after one Force India star recently explained his desire to leave the team to fight for major honours, the Silverstone-based outfit have indicated Nico Hulkenberg, still without a podium finish in five full seasons in F1, would be allowed to depart if a front-running team made an approach.
With this year's driver market set to be particularly eventful, IndyCar's Ryan Hunter-Reay believes drivers competing in American open-wheel racing should not be ignored in the fight for an F1 seat.
Closing our latest roundup is Red Bull's Adrian Newey, who has become the latest paddock figure to question the proposed 2017 regulation changes.
