Tajima teams up with Rimac for Pikes Peak 2015
Zagreb, May 2015. – Team APEV with MONSTER SPORT, led by the racing legend Nobuhiro “Monster” Tajima, teamed up with Rimac Automobili.
As a result, 2015 Pikes Peak International Hill Climb Race will have a new 1.1 MW beast at the starting line, the Tajima Rimac E-Runner Concept_One.
Rimac Automobili are once again showing their vigorous racing DNA taking the challenge in one of the most prestigious races in the world. Mr. Tajima’s decades long experience in racing and Rimac Automobili’s state of the art technology and know-how brought to life a staggering creation, the Tajima Rimac E-Runner Concept_One. It is powered by four independent electric motors, giving the car a total power of over 1,1 MW (1,475 HP). That is more than twice the power Mr. Tajima had in his 2014 car when he broke his own Pikes Peak record, stopping the clock at 9:43,90.
There are no gearboxes or differentials on this car. The power of each independent motor is transferred to each wheel by an innovative chain drive system developed specifically for this project, which saves a lot of weight and space. Embracing the Rimac Automobili technology, the Tajima Rimac E-Runner Concept_One features an adapted racing version of the Rimac All Wheel Torque Vectoring system, first implemented in the Rimac Concept_One. The Rimac AWTV controls the torque of each motor 100 times a second. The system can vary the torque on each wheel depending on the steering angle, speed, longitudinal and lateral forces, yaw-rates and number of other variables. The ECU runs the collected sensor-data through complex mathematical algorithms which calculate the optimum torque distribution on a millisecond-level. This enables the vehicle to take full advantage of the tires, squeezing the maximum out of their potential and giving the driver the desired vehicle dynamics at any given moment. Mr Tajima will thus have both the 1,1 MW of power and maximum grip in each of the Pikes Peak’s 156 corners.
The Pikes Peak hill climb is 19,9 km long and ends up at 4,301 m above sea level. Petrol engines have oxygen starvation problem at that altitude – the power of the engine decreases over 40 percent. However, electric motors don’t use oxygen, so Mr. Tajima will have the full power of all four electric motors available from start until the finish line.
Pikes Peak race
The Pikes Peak International Hill Climb race in Colorado has taken place since 1916. On average it features around 130 competitors from all over the world. This year the event is starting with practice sessions on Tuesday, June 23rd, culminating on race day, Sunday June 28th.
The track is 19,99 km (12,42 miles) long, has 156 turns climbing 1,440 m (4,720 ft) from the start at Mile7 of the Pikes Peak Highway, to the finish at 4,300 m (14,110 ft).
