What’s the
TOYOTA BARISTA PROJECT?

TOYOTA BARISTA. A car company making coffee?
Here’s what happened.

Well, we suggest you have a cup of coffee and in the meantime we’ll explain this to you.
When you’re driving your car and step on the brakes, friction occurs giving off heat. Actually, that heat itself is a fine source of energy. But, in most cars that energy is not used any further, and that is a real waste.
With that in mind, Toyota has developed a way to recover the energy lost when the car decelerates, storing the regenerated energy in the battery. It’s called the “Kinetic Energy Recovery System”.
The name may make it sound difficult, but it is an incredible technology that is sure to lead the future of car manufacturing. To better understand its miraculous power, we wanted everyone to experience it in a more familiar situation, like having a cup of coffee. And that’s what the TOYOTA BARISTA PROJECT is all about. Sounds good, doesn’t it?

Project Movie

The idea was to take the energy wasted during braking and reuse it to accelerate the car again.
Through the harsh conditions of motor-racing, Toyota has improved the basic hybrid technology for greater capacity and higher efficiency.
We will introduce one aspect of this technology as we move backstage.

Special Morning Breakfast Plate

The climax of a race event. A plate of breakfast, prepared using the energy generated through braking or deceleration. One cup of coffee, half a slice of toast and one-third of a sunny-side up fried egg. The strange portion calls for an explanation.

You surely have heard of the 24 Hours of Le Mans before.
The energy recovered and reused in the Toyota race car when decelerating on that circuit amounted to 6,000,000 joules for each lap around the track! (The energy unit may sound somewhat unfamiliar.)
Energy that would have been wasted adds up to quite a large amount.
Reconnecting these 6,000,000 joules of energy with a familiar situation, it is actually the amount of energy needed to prepare the numbers of cups of coffee, slices of toast and fried eggs listed below.

Coffee=

000.0

Toast=

000.0

Fried eggs=

000.0

Dividing it all up fairly among 171 people, each person gets one cup of coffee, half a slice of toast and a third of a sunny-side up fried egg. *4
Now is it clear?

  • Our calculations:

  • *1: One coffee siphon energy usage per second (with 80°C hot water): 350W=350 joules / time to make 3 cups of coffee: about 5 minutes / number of cups: 6,000,000 ÷ (350x300) x 3 = 171.4cups/lap
  • *2: One toaster energy usage per second: 800W=800 joules / time to make 2 slices of toast: about 3 minutes / number of slices: 6,000,000 ÷ (800x180) x 2 = 83.3 slices/lap
  • *3: One IH heating plate energy usage per second: 1300W / time to make one fried egg: about 1 minute and 20 seconds / number of fried eggs: 6,000,000 ÷ (1300x80) = 57.7 eggs/lap
  • *4: The morning breakfast plate shown in the clip is based on the energy recovered in three laps of the Le Mans circuit.

  • *Note: the race car that appears in the video varies slightly from the actual race car.

BARISTA

We proudly introduce TOYOTA GAZOO Racing active driver, Kazuki Nakajima, who was responsible for preparing your special morning breakfast plate with his amazing driving technique.

After his debut in four-wheel racing, he rose to a champion Toyota Formula driver in 2003. He competed in the Japanese F3 and then in 2006 joined the Toyota Young Drivers Program (TDP) in Europe where he competed in the European F3 and GP2. In 2007, in addition to GP2 he became an F1 test driver and a regular F1 driver the following year, competing in 2 series. In 2012, he joined the Toyota WEC Project, and in 2014, he became the first Japanese driver to gain the pole position at the 24 Hours of Le Mans.

COFFEE MAKER

Another main player: The creator of the energy for the special morning breakfast plate is the TOYOTA TS040 HYBRID, working closely together with the barista.

Competing in the FIA World Endurance Championship (WEC) the TOYOTA TS040 HYBRID is the ultimate race car, seeking to combine driving pleasure with the efficiency of hybrid driving. Toyota's leading technology pioneered with the Prius in hybrid technology, and now the Toyota Hybrid System Racing (THS-R) is used in the powertrain to output a mind-boggling power of 1000 PS.

MECHANISM

The essential heart of the high-performance hybrid is the “Kinetic Energy Recovery System”. Let us reveal what is happening in the car.

Imagine putting on the brakes to decelerate a race car traveling at speeds of up to 340km/h. In fact, an enormous amount of energy is lost as heat. But, that energy, normally lost as friction heat under deceleration, is converted into electrical energy, which is recovered in the battery to be reused later.
The Toyota high-performance hybrid allows the ultimate in both driving pleasure and efficiency. Hybrid technology developed through the harsh demands of racing will also be applied in hybrid technology to benefit all TOYOTA production cars on the road.

  • Going into a corner at speeds of up to 340km/h and slamming on the brakes.
  • Energy generated by braking is recovered as electric energy in the Motor Generator Unit (MGU).
  • The enormous energy generated momentarily can be stored in a supercapacitor.
  • With acceleration, the stored energy drives the MGU.
    Power from the motor is added to that from the engine, resulting in an acceleration power of up to 1000 PS.

STAGE

Our “Barista” has run the Circuit de la Sarthe ? the scene of the 24 Hours of Le Mans.
In 2014, Toyota became the first Japanese winner of the World Endurance Championship.

FIA World Endurance Championship (WEC) is a world competition presided over by the International Automobile Federation (FIA). Toyota participated in the hybrid car category LMP1-H with the prototype racing car TS040 HYBRID in 2014 and it was the first time a Japanese manufacturer won the World Endurance Championship.
During the 2015 season, Toyota is participating in 8 international racing circuits including the 24 Hours of Le Mans.
