Former racer turned Sky Sports F1 commentator Martin Brundle has said he is expecting 'total calamity' in the early part of the 2014 F1 season.

The sport will adopt new 1.6-litre turbo-charged engines next years, while teams will also make greater use of energy recovery systems as F1 looks to improve its green credentials. There are also other revisions - to things like aerodynamics - and Brundle believe this all threatens Red Bull's run of supremacy.

"I'm expecting total calamity in the early stages of 2014 and it remains to be seen if that's entertaining or confusing, but I have no doubt that these brilliant engineers and designers will master the issues sooner than later," Brundle wrote in his most recent column on Sky Sports F1.

"I agree with Jenson Button, big changes can only hurt Red Bull given they have such an advantage, but no doubt the usual suspects with the biggest resource will get there first. I'm hoping that we won't have a three-tier Ferrari - Renault - Mercedes championship in whichever order for both power and efficiency, but it's possible.

"I've asked my trusted sources in the paddock and they just roll their eyes and throw their arms up in the air. There's a huge amount of work to do in a very short space of time."

Brundle also warned of a crisis in the sport given a lot of the teams are struggling to balance the books: "The midfield driver market should settle down in the next week or so," he added prior to confirmation that Pastor Maldonado will go to Lotus in 2014 and Nico Hulkenberg will re-join Force India.

"I've never seen anything like it frankly, and it doesn't bode well when the only team - Lotus - to consistently take the fight to Red Bull can't afford to chose its own driver line-up and take the best available.

"My alarm bells are going off for the general health of F1 and it needs urgent action, if not then a crisis, before it's back on track."
