Over the past couple of days a stream of 2012 F1 cars have broken cover. Lotus F1 Team (formerly Renault) launched their E20 with this YouTube video featuring Jonny Smith.

Today Red Bull pulled the covers off the RB8, which designer Adrian Newey says is a continued evolution stemming back to the RB5. Will this be the car to take Vettel to a hat-trick of World Championships?

Meanwhile at Jerez in Spain, the Sauber outfit debuted the Ferrari-powered C31. “The C31 is revolutionary where we had fresh ideas, particularly at the rear of the car” said chief designer Matt Morris. “And it is an evolution where we knew we could carry over certain approaches.”

With last year’s driver line-up of Jamie Alguersuari and Sebastien Buemi dropped, it will be Daniel Ricciardo and Jean-Eric Vergne who will drive the Toro Rosso STR7s.

Pre-season testing gets under way tomorrow at Jerez, with the Championship kicking off in Australia in just over a month.
