TS040 HYBRID Race Car will challenge Audi and Porsche in the
FIA World Endurance Championship and at Le Mans
Paul Ricard, France
– on the 27th March, Toyota Racing has revealed the TS040 HYBRID car
and improved driver line-up to compete in the 2014 FIA World Endurance
Championship.
Toyota said that this
TS040 HYBRID will bring the company into a new era of hybrid motorsport,
stating that this race car is the most advanced hybrid technology in racing.
With 480PS (473 hp, 353 kW) of four
wheel-drive hybrid boost in addition to the 520 PS (513 hp, 383 kW) 3.7litre petrol engine, the TS040
HYBRID, launched today at Circut Paul Ricard, has maximum power of 1000PS (986 hp, 735 kW) and
represents the most advanced hybrid technology in racing.
The move to a four-wheel drive hybrid sees Toyota return to a concept
which has been part of its racing hybrid development since 2007, when the four
wheel drive Supra HV- R became the first hybrid to win an endurance race, the
Tokachi 24 Hours.
Toyota explained the new
hybrid system designed for racing has been developed specifically for the
revised WEC technical regulations, which put a particular focus on fuel
economy. A fuel flow meter will monitor fuel usage and penalties will be
enforced in the race if the three-lap average consumption exceeds defined
limits. The fuel allowance is determined by the level of hybrid capacity each
team commits to. Toyota Racing has opted for 6MJ of hybrid capacity per lap at Le Mans.
Working together
with official partner TOTAL, TOYOTA Racing’s engineers have found further
efficiencies and performance through the use of customized TOTAL lubricants.
The new, more open
regulations have allowed TOYOTA Racing to implement a major increase in hybrid
power, with an AISIN AW motor - generator on the front axle added to compliment
the DENSO unit on the rear.
Under deceleration,
the motor-generators apply braking force in combination with traditional
mechanical brakes to harvest energy, which is transferred via inverter (AISIN
AW at the front, DENSO at the rear) to the NISSHINBO super-capacitor. During
acceleration, the motor/generator reverses its function acting as a motor to
deliver a 480PS power boost.
That four-wheel drive hybrid power is allied to a normally – aspirated V8 engine, both having
been developed by Motor Sports Unit Development Division at the Higashifuji
technical centre, where next-generation TOYOTA road car technology is born.
Toyota has already sold 6
million hybrid road cars since the launch of the Prius in 1997. Know-how from
the TS030 HYBRID is already in use to enhance TOYOTA’s road car hybrid
and WEC’s focus on road-relevant technology is expected to see further
technology transfer from track to road.
The TS040 HYBRID
chassis is designed, developed, manufactured, built and operated by TOYOTA
Motorsport GmbH (TMG) in Cologne.
Particular attention has been paid to airflow
around the car, both to reduce drag in order to improve fuel economy and to
increase downforce, and therefore grip, levels to compensate for tyres which
are 5cm narrower compared to 2013.
Extensive development in TMG’s state-of-the-art wind
tunnels has resulted in an aerodynamically-efficient design which is also
incredibly lightweight thanks to advanced composite design and production
processes.
Intensive simulation and calculation work at TMG has
refined the TS040 HYBRID, utilising hardware-in-the-loop technology to test
individual components based on real track data and powerful calculation
computers to optimise designs.
Such cutting-edge techniques are significantly more
efficient than track testing, allowing TMG engineers to continue optimising all
aspects of the TS040 HYBRID chassis and lay-out for longer than rivals relying
on traditional methods.
A slight reshuffle of the driver line-up sees Alex
Wurz, Stéphane Sarrazin and Kazuki Nakajima share the #7 car while Anthony
Davidson, Nicolas Lapierre and Sébastien Buemi are in the #8.
The TS040 HYBRID made its track debut at Paul Ricard
on 21st January and has subsequently completed 12 days of testing across
Europe, covering around 18,000km.
