Monster Tajima Bringing 1,475 HP Rimac EV To Pikes Peak
Last week Rimac Automobili teased its latest endeavor in a brief video, though it didn’t take much digging to find out what they had in store. Rimac teamed up with famed Pikes Peak racer Monster Tajima to build a new 1.1 Megawatt/1,475 HP electric vehicle that they hope will set a new overall record for the famous Race to the Clouds.
Tajima already set a new record for the electric vehicle class back in 2013, climbing the hill in 9-minutes and 46 seconds, matching Rhys Millen’s record run from the previous year. In other words, EVs aren’t that far behind the combustion-powered race cars, and Tajima seems single-minded in his goal despite coming up short of the overall record. That’s why he turned to the electric vehicle expertise of a company like Rimac, which built the 1,088 horsepower Concept_One at a time when many automakers are struggling to build even basic EVs.
What Rimac came up with is the Tajima Rimac E-Runner Concept_One, an all-wheel drive race car with four independent hub electric motors, one at each wheel, eliminating the need for both a transmission and differentials. That means nearly 100% of the power generated by each motor is put directly to the road, and instantaneously at that. The E-Runner also gets the Concept_One’s All Wheel Torque Vectoring (AWTV) system that adjusts power output in each motor more than 100 times per second. That means a whole lotta handling ability, especially important for the Peak’s 156 turns across its 12.42 mile course.
We measured 0-100 km/h in 2,2 seconds. 200 km/h comes in 5,4 seconds from a standstill. Cornering forces and stopping numbers are also impressive, but let’s not spoil the surprise. We are quite confident that Tajima Rimac E-Runner Concept_One will break previous year’s record. He is a great driver with tons of experience. Interesting fact – he raced Pikes Peak his first time a year before I was born. 28 years later, we work alongside to push the limits further. With the support of our best engineers and technicians, our technology, powertrain, battery-system and Torque Vectoring, he will be able to push the boundaries of electric race cars to a whole new level. Working with Mr. Tajima and his team is an amazing experience of which we enjoy every second,” says found Mate Rimac.
On board will be a 57 kWh battery pack of Rimac’s design, pushing the E-Runner to a top speed of 270 KPH/167 MPH, and darting from 0 to 60 MPH in 2.2 seconds. Because it only needs to go 12.42 miles, there’s no real worry about total driving range, though I doubt Rimac made the battery any bigger than absolutely necessary considering the E-Runner weighs just 1,500 kgs/3,306 lbs. On paper, it’s the perfect Pikes Peak racing machine, but the mountain is not known for being easy or forgiving, and he won’t be the only racing legend in an electric vehicle this year.
Can Monster Tajima make history with a Rimac-built electric race car? We find out at the end of this month.
