2005 FERRARI F1 CAR (F2005)

R Brawn (Tech Director): "There are no radical features of this car but logical progressions in all the areas that we feel make a good racing car ... It is stiffer, lighter, more stable, and, most importantly with the new tyre regulations, it should be less stressful on the tyres. The transmission is a further progression, now utilising more carbon in the structure to improve stiffness and reduce weight ... Aldo Costa has been responsible for the entire F2005 project and I would like to congratulate him and his team who have carried out the research, structural calculation and design of the car and met all the objectives we defined at the start of the project"

2005 TOYOTA F1 CAR (TF105)

Tsutomu Tomita (Principal): . "Our ultimate goal is to win in F1 ... But we know it takes time. Our target with the TF105 is to make an important step on our way to victory"

Luca Marmorini (Tech Director Engine): "... We started at a very early stage to develop an engine that was increasingly reliable. During 2004, we began to improve the reliability of specific parts in the engine, and in fact we already used some of these parts in the RVX-04 model ... Creating an engine to last somewhere in the region of 1,500 kilometres was an enjoyable and interesting technical challenge. I am confident that the RVX-05 will reflect our excellent in-house technical capabilities."

2005 WILLIAMS BMW F1 CAR

JAN 7, 2005, BAHRAIN - NEW LIVERY LAUNCH
JAN 31, 2005, VALENCIA - OFFICIAL LAUNCH (FW27)

S MICHAELS (TECH DIRECTOR): "... This car reflects a philosophy of concentrating on the fundamentals. Our focus throughout the design cycle has been built around simple variables that affect performance, such as reducing weight and friction while increasing stiffness. As a consequence of focusing on these fundamentals, we have reverted to a single keel configuration for the front suspension geometry.We have also been aggressive with our cooling, as witnessed by the extremely low engine bodywork and the large sidepod undercuts. Reliability is the final area we have been determined to pursue, and we have made significant progress, specifically with the gearbox which has been running on-track since November 2004 without problems."

2005 BAR HONDA F1 CAR

BAR Honda 007

Geoff Willis (Tech Dir): "... The 007 is an evolution of the very successful 2004 car. We reviewed where our strengths and weaknesses were and what we needed to do for 2005. We dug down into everything and decided we needed a brand new chassis, brand new engine, brand new transmission, we've taken out a lot of weight, there's a lot of new technology in there and it is very much better integrated - showing the year by year improvement between the chassis engineers"

2005 RENAULT F1 CAR

RENAULT R25

Pat Symonds (Engineering director): "... I feel good about it. The measurables, things like engine power, have improved despite the engine being longer life"
Bob Bell (Tech Director): "... In recent years, we have seen two schools of thought evolve in front suspension design: the traditional single keel, with a single front lower wishbone, and the twin keel, which brings a measurable aerodynamic gain but can also have a structural penalty outweighing the benefit ... We believe the v-keel is a very elegant solution to this dilemma, as it combines the virtues of both systems: we have obtained an aerodynamic advantage for minimal structural penalty, while maintaining our preferred mechanical configuration for the front suspension"
