Big changes are afoot for the 2014 Formula 1 season, most notably in the form of a new 1.6-litre turbocharged V6 engine that will replace the naturally-aspirated 2.4-litre V8s of old.
New rules also state that the machines must be more fuel efficient and environmentally friendly so a maximum 100kg fuel limit will be imposed on all cars. The race has been on to manufacture engines that not only perform to the highest levels but also sup as little fuel as possible to ensure the cars actually finish each race.
Aerodynamic changes have also put an end to exhaust diffusers the formerly used exhaust gasses for extra downforce. The front wing must also be skinnier and lower to improve safety.
The result of the new rules is a car that looks very different to Formula 1 racers of old but that hasn't stopped manufacturers shouting about their latest creations.
Here's a summary of the big names that have released information and imagery so far...
The car is due to be driven by the dynamic duo of Fernando Alonso and Kimi Raikkonen, providing a skillful advantage from the outset. This Ferrari is noticeably more compact than previous offerings, boasting a cinched waistline and bizarre 'anteater' nose cone that funnels as much air underneath the front wing as possible.
Again, the McLaren is a far more lithe-looking machine than the beefed-up V8-powered cars of old. The nose cone is exceptionally skinny, featuring flared 'nostrils' that manipulate air around the front of the car. The rear wing is also narrower, while diffusers and further aerodynamic gadgets now occupy the space that was previously taken up by a much larger engine. A McLaren spokesperson recently told us that an update for the car is designed and developed every 20 minutes, so expect to see a shifting silhouette as the season progresses.
All eyes are on the nose this season, as manufacturers attempt to tackle the aerodynamic rule changes in their own idiosyncratic ways. Lotus has opted for a 'two-pronged' approach that leads into a gently sloping nosecone. Romain Grosjean and ex-Williams driver Pastor Maldonado will take to the wheel in what is shaping up to be a very exciting season.
Adrian Sutil and Esteban Gutierrez will hopefully be piloting the Swiss team to success in 2014 and the car they will be racing in will feature a 'snout-like' nose and a heavy reliance on energy recovery systems. "Together, these changes present the engineers with a huge challenge, especially with time pressure also a major factor," commented Sauber's chief designer Eric Gandelin.

Team principal Vijay Mallya is playing his cards close to his chest when it comes to revealing gritty details about the new car but we do know that a new partnership with Mercedes will see a brand new drivetrain installed. Nico Hulkenberg and Sergio Perez will drive the vehicles that will have an "updated front end" when the chequered flag drops in Australia on March 16.
