The waiting is over guys! The 400 hp gasoline-electric weaver Toyota Yaris Hybrid-R Concept has been unveiled at this year’s Frankfurt Motor Show.
Inspired by Toyota’s endurance racing technology, the Hybrid-R concept showcases the possibilities of combining high-efficiency gasoline engines with the shear force of individually working electric motors for achieving both city and track performances.
Until now, Toyota’s hybrids (Lexus included) used one or two electric motors, which were integrated in the vehicle’s gearbox (see how Prius gearbox works here). The Hybrid-R technology will change that by separating the motors from the rest of the mechanical powertrain in order to achieve better force distribution and handling.
The Toyota Yaris Hybrid-R Concept uses a hybrid powertrain made of a 300 hp 1.6-liter turbocharged gasoline engine and three electric motors, each being able of developing the equivalent of 60 hp.
One of them is integrated in the vehicles’s gearbox and it operates as a generator in two situations - it recharges the super capacitor during deceleration and directly powers the other two electric motors during acceleration.
The remaining electric motors are situated at the back, one for each wheel, both working as boosters, aiding the front-wheel-driving gasoline engine during acceleration. They can also be used for short distance EV driving, when the vehicle is set for “Road” and the speed is low enough.
Another important function these two electric motors will perform is the fact that they can function independently, so during hard cornering, the torque on the rear axle can be distributed differently for the inner and outer wheel enabling the car to be more maneuverable.
Now, with all this knowledge, all is left to do is to lean back and have a look at the first pictures with the Hybrid-R Concept in flesh and bone.
