Team Lotus (the on that was called Renault before) Sauber and Scuderia Toro Rosso have all unveiled their 2012 F1 cars over the past 24 hours.
Lotus E20
Lotus revealed its 2012 E20 in an online broadcast from its factory Sunday before demonstration runs at Jerez Monday ahead of the start of winter testing on Tuesday.
A more traditional car among designs unveiled so far, the Lotus does feature the stepped nose design now commonplace, and reverts to a traditional exhaust layout - as mandated by the 2012 regulations - after last year's experiment with a forward exiting exhaust.
The car is the first to be entered by the ex-Renault team under the Lotus title after the end of the branding dispute with rival team owner Tony Fernandes, whose erstwhile Lotus squad now runs as Caterham and the E20 keeps the traditional black and gold colours used by the original Lotus F1 team in the 1970s and 80s
Sauber C31
Sauber also took the wraps off the new Ferrari-powered C31. The Swiss squad finished in seventh place in the standings in 2011and managed to keep rival Toro Rosso at bay thanks to two point-scoring results in the final races of the seaso to secure seventh position.
The team will have an unchanged line-up for 2012 in Kamui Kobayashi and Sergio Perez.
"Our goal is to finish regularly in the points so as to put ourselves in a significantly better position in the world championship," said team boss Peter Sauber. "We are looking forward to another season working with our young and talented drivers.
The C31 continues with the trend set by other teams and it incorporates a stepped noseand a new pull-rod design for its rear suspension, allowing for improved packaging of the rear spring and damper elements.
Sauber's new car is expected to complete its first run at Jerez later this morning.
Toro Rosso SRT7
Rivals Toro Rosso pulled the covers off their new SRT7 powered by Ferrari engines for the sixth season in a row and to be driven by Daniel Ricciardo and Jean-Eric Vergne after the team opted for an all-new line-up for the upcoming season.
"The STR7 is the third car designed, fabricated and assembled completely by Toro Rosso," team boss Franz Tost pointed out. "We have invested a lot of money to build up the infrastructure and I hope the results will be good in the forthcoming season. This investment was only possible because we have strong partners.
The new car will take to the track for the first time Tuesday, with Australian Ricciardo doing the driving.
