Rimac Automobili and Team APEV with Nobuhiro “Monster” Tajima as  the driver officially unveiled an all-new race car Tajima Rimac E-Runner Concept_One for 2015 Pikes Peak International Hill Climb Race scheduled of June 28.

This is real beast with 1.1 MW power and 1500 Nm of torque. Power output is more than twice that of last year’s Monster car.

Four independent motors for AWD are connected to the wheels via chain drive system and controlled by a racing version of the Rimac All Wheel Torque Vectoring.

“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.”

And look at the performance – 2.2 seconds to 100 km/h (62 mph) from a standstill! To reach 200 km/h takes a total 5.4 seconds!

Mate Rimac reveals:

“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.”

“Power output is more than twice that of last year’s Monster car.”

Woah… I don’t know what kind of feeling just flushed through my head. Reading that, it was definitely intoxicating! Ahh! I don’t know what to say about all of this!

Also… CHAINS? This is going to be epic if this car wins. Just imagine, it did this well, has one “MEGAwatt” of power, it is driven by chains and it’s partly built by the Croatians.

Anyway, I hope that 0-60 time would make serious records in the higher altitude part of the track.

Ah, I love this race!

Chains are very efficient.

And light!

The Numbers are Far Bigger – but I had a tiny Taste of a power doubling – back in 1984 – when I bought my Mazda RX7 – with Aftermarket Arkay Turbo System that boosted the little 100 Hp 12A Wankel up to 205 HP! I never drove a Stock one at the time – but the one I had could Rev to Read-line in all 5 Gears! Read-line in 1st & then in 2nd, (Sure Felt Like They) were within 2-3 seconds as well!

This will be epic! So want to be there to witness their run!

1.1 MW is more than 1100 hp it is about 1475hp

Faster than a Slot car…..amazing!

So the Tesla P85D family sedan is within ~0.9sec 0-60mph of this go-fast beast?

That’s nearly 50% slower. And then the tesla overheats at the 4th or 5th corner. This a race car with race car cooling systems.

Yes that’s the major difference with this car and all the other race EVs. They need to last at least 10+ min constantly accelerating uphill!

Tesla’s peak output can’t be sustained for long due to known overheating issues. When Motor Trend tested the P85 on a normal circuit (NOT top speed run, moderate speed, lots of curves, high overall duty cycle) it overheated before it completed the first lap

The Model S overheats when run at “moderate speed”? Um… no.

The infamous case of the stock (unmodified) Model S overheating before even the first lap was completed was run on the 14-mile Nurburgring “Green Hell” road race course, not on an oval racetrack, not by Top Gear, and under full power. That is, as fast as the car could go on the course.

Here’s the InsideEVs’ report:


Contrariwise, there’s at least one video of someone running a Model S at top speed, 125 MPH, on the Autobahn for almost 12 minutes without overheating:


As noted in the discussion linked below, you can’t take any unmodified mass produced car and run multiple maximum speed laps on a race track, and expect it to be trouble free. The Model S is not a track car.


NO. Read Motor Trend’s test on a conventional track at Leguna Seca in California. NOT a high speed test. NOT an oval. NOT the authobahn. Like I mentioned, high duty cycle i.e. stomping on the accelerator at every corner exit.


“But once at Laguna, our lapping hopes were hobbled by a temperature protection that gradually dialed back full power during Randy Pobst’s flat-out flogging.”

A top speed run is actually less taxing for the P85 because once you reach steady state, the power requirement for 130mph (~110kW) is well under the “overheat” power reduction level (power reduces to half power 160kW).

A track is different because you have constant heavy power demand from the need to accelerate (way more than ~110kW).

0 to 200 km/h in 5.4s compared to 13-14 s for P85D. Model S is a great car in it’s category, but it doesn’t comapare to race cars.

I wonder if there are any plans to make a street legal version of this car? A Tesla version of the the Porsche 918 or the P1.

It would be totally pointless but there is a part of me that would love to see Nuremberg street legal lap record held by a BEV. Especially since there are a couple of hybrids in the top ten already.

The only thing better would be if it was held by a slightly over weight woman in her 40’s driving a BEV that was small and goofy looking…. potentially painted pink or purple and made by KIA.

Rimac’s street car is called the Concept One, and it is mentioned in the article. It looks stunning, and has a potent AWD system with a motor for each wheel, like Rimac’s 1.1 MW race car.


it’s a fair cop, sorry about the reference to the car that already exists.

The headline is wrong. The correct power is in the text. 1.1MW or 1474 HP.

A chain drive car won the race in 1966 when I was there watching it, sprayed me with a bunch of gravel as the front wheels were spinning—an Olds Toronado.

It will race all the way up and then regen all the way down… LOL

You can’t compare 2.2 second run with a 3.1 second 0-60 mph run. Its kind of like saying a 11 second qtr mile car is “only” 2 seconds quicker than a 13 second car. Yet all things being equal, it is about a 200hp difference when comparing street cars.

Also…something very amazing: Doing that entire run on only a 57kwh battery. Thats less than 2 gals of gas in equivalent energy.

the first of many great victories

Yes, and it’s still the infancy of electric drive.
Oh boy, what a wonderful world!
