Toyota Racing has been took the wraps off the new TS040
Hybrid, the car which will take the team into the 2014 FIA World Endurance
Championship and a new era of hybrid powered motorsport.
The new car, revealed at the Paul Ricard
circuit in the South of France, represents the most advanced hybrid technology
in modern racing. Tomorrow it will begin an official championship test session,
prior to making its competition debut at the season-opening Six Hours of
Silverstone race on 20 April.
Toyota will be taking on rival manufacturers Audi
and Porsche with a car that benefits from 480 PS of all-wheel
drive hybrid boost in addition to the 520 PS produced by its
3.7-litre V8 petrol engine, taking maximum power to 1,000 PS.
The new powertrain has been developed in line with
revised WEC technical regulations, which put an emphasis on fuel economy. Teams
are required to use 25 per cent less fuel than in 2013, with savings achieved
through changes to powertrains, aerodynamics and driving style. By adopting
more road-relevant technology, the WEC will increase the possibilities for the
transfer of Toyota’s race-bred technical know-how to its production cars,
strengthening is status as the world’s leading manufacturer of hybrid vehicles.
Toyota Racing have made gains in efficiency and
performance by using specialist lubricants they have developed with their
official partner, Total. The more open regulations have also allowed the team
to engineer a major increase in hybrid power, using a new motor-generator on
the front axle in addition to the unit at the rear. Under deceleration, these
motor generators apply braking force in combination with the traditional
mechanical brakes to harvest energy, which is then transferred via an inverter
to a super-capacitor. When the car accelerates, the motor-generators reverse
their function, delivering a power boost to all four wheels.
The V8 engine has been engineered at the Higashfuji
technical centre, the research base where Toyota’s next-generation road car
technology is also developed. The TS040 Hybrid’s chassis is designed, developed
and manufactured by Toyota Motorsport (TMG) in Cologne, Germany. It marks a
major evolution of last year’s TS030 Hybrid, incorporating design changes
dictated by the new championship regulations, including a maximum width reduced
by 10cm and the adoption of additional safety features.
Particular attention has been paid to managing
airflow around the car, not only to reduce drag and improve fuel economy, but
also to increase downforce and grip to compensate for the use of narrower
tyres. The final design has been honed in TMG’s wind tunnels and rendered
exceptionally lightweight thanks to the use of advanced composite technologies
and production processes. Individual components have been put through intensive
computer simulations using real track data to ensure optimum performance in
race conditions.
The TS040 Hybrid has already completed 12 days of
testing across Europe since January and it will undergo a further test
following this week’s prologue event ahead of its first race.
