Formula one 2009 car unveilings

McLaren - Car: MP4-24 Technical details: Clean lines in conformity to new regulations. McLaren say this car will look quite different by the first race. Drivers: 1 Lewis Hamilton, 24, GB; 2 Heikki Kovalainen, 27, Finland Maurice Hamilton's verdict: McLaren have the resources to deal with far-reaching technical changes and seem well prepared. Heavy test programme will bring planned changes Photograph: David Davies/PA

Ferrari - Car: F60 Technical details: Wide front wing, narrow and tall rear wing conforming to 2009 regulations. Severely waisted rear end to chassis to assist air flow and cooling for electronics. Kers system, using batteries. Drivers: Kimi Raikkonen, 29, Finland; Felipe Massa, 27, Brazil Maurice Hamilton's verdict: Struggling to make Kers work and a decision whether to race with the kinetic energy retention system will not be made until late March Photograph: Reuters

Williams Car: FW31 Technical details: Novel aerodynamic treatment to front wing and slightly bulbous nose cone. Kers system utilising flywheel instead of batteries. Drivers: Nico Rosberg, 23, Germany; Kazuki Nakajima, 24, Japan. Maurice Hamilton’s verdict: Interim colour scheme prior to launch of official livery next month. Clean, efficient looks and advance testing of parts suggest this may be the car to return former champions to where they belong Photograph: Armando Franca/AP

Renault Car: R29 Technical details: Broad nose cone. Different aerodynamic treatment to sidepods as heavily undercut rear section folds under to assist exit of air. Shark-fin engine cover. Drivers: Fernando Alonso, 27, Spain; Nelson Piquet Jr, 23, Brazil Maurice Hamilton’s verdict: Will run Kers (battery) system at first race.

Toyota - Car: TF109 Technical details: Toyota will not use Kers system until later in the season, if at all. There is a less adventurous use of side pods than Ferrari. Drivers: 9 Jarno Trulli, 34, Italy; 10 Timo Glock, 26, Germany. Maurice Hamilton's verdict: Toyota are continuing trials with Kers until satisfied that it is safe. They are preferring to save weight and gain design flexibility by not carrying the batteries needed for Kers. Photograph: EPA

BMW - Car: F1.09 Technical details: A conventional approach to the technical changes; no surprises, on the surface at least. Kers battery system. Drivers: Robert Kubica, 24, Poland; Nick Heidfeld, 31, Germany. Maurice Hamilton’s verdict: Despite being better prepared than most, remain undecided about the energy retention system. BMW strongly opposed suggestion by rivals that its introduction should be postponed a year. Photograph: Kai Foersterling/EPA

Red Bull – Car: RB5 Technical details: Adventurous interpretation of revised regulations brings striking design. Long, high nose; small sidepods; intricate treatment of front wing detail. Drivers: Mark Webber, 32, Australia; Sebastian Vettel, 21, Germany. Maurice Hamilton’s verdict: A month longer gestation period than Ferrari or McLaren has allowed Adrian Newey to exercise his flair. Less testing as a result may be a long-term handicap. Renault engine will benefit from concession allowing performance update. Photograph: Mark Thompson/Getty Images

Force India - Car: VJM02 Technical details: Using Mercedes-Benz engine, gearbox, hydraulics and Kers system. Drivers: Giancarlo Fisichella, 36, Italy; Adrian Sutil, 26, Germany. Maurice Hamilton' s verdict: November decision to switch from Ferrari to Mercedes engine and transmission means late appearance. Only two test sessions remaining before test ban and will hamper development and reliability checks. May miss driving force of Mike Gascoyne, former technical director. Will be hard-pressed to move from back of grid Photograph: Handout/Getty Images

Red Bull – Car: STR4 Technical details: Design by parent company, Red Bull, means striking resemblance to RB5. Continue with Ferrari engine and transmission, plus Ferrari’s Kers system. Drivers: Sebastien Buemi, 20, Switzerland; Sebastien Bourdais, 30, France. Maurice Hamilton’s verdict: Despite protestations that this car is quite different because of Ferrari engine and its installation, the STR4 has all the hallmarks of Adrian Newey’s Red Bull – which is no bad thing. The small, efficient Italian team will sorely miss Sebastian Vettel Photograph: Toni Albir/EPA

Brawn Grand Prix – Car: BGP001 Technical details: Mercedes-Benz engine, gearbox, hydraulics and Kers system. Drivers: Jenson Button, 29, Great Britain, Rubens Barrichello, 36, Brazil Maurice Hamilton’s verdict: A mammoth task ahead as the former Honda team made a late appearance at the last test of the winter. No one is better equipped to manage the catch-up as two experienced drivers and Ross Brawn, Ferrari’s former technical chief. Photograph: Jasper Juinen/Getty Images
