Yup, that's 4 wheel torque vectoring.

 

[TEG]

It sounds loud. Is that gearbox whine?

 

[WarpedOne]

No, that is a whine of four straight-cut reduction gearboxes.

I got the impression that "smooth" is not in the set of words that describe the drive of this car.

 

[Phil K]

Awesome! It's like the Lambo of electric cars.

 

[WarpedOne]

More like a Bugatti.

Your answer should have been Yes.

New teaser from Rimac. Comments speculate a Pikes Peak attempt with Monster Tajima at the wheel.

Rimac at Formula E. Looks as if Mate forgot the design a charge port :wink:

2.8s 0-60mph @ 1088hp doesn't seem quick enough considering the "(arguably 200hp less than) 691hp" of the P85D sedan does 3.1

Am I missing something?

I would speculate that the same caveat that applies to the P85D also applies to the Rimac car -- there's 1088hp worth of motors in the car, but it's not all accessible at the same time.

They really should put an asterisk (*) on that paint job everywhere it says 1088hp.

Putting all that power to the ground is the issue. This car *should* be able to do 0-100 at 2.2-2.4 seconds, right? I'm wondering what the gear ratio is, if it's the same on the front and rear wheels and if there is a compromise between acceleration and top speed (like in all fixed gear EVs). I can't imagine them going with multiple gears.

 

[Jaff]

Could it be in the gearing?...I assume the Rimac has a much higher top end than the P85D...

Rimac Concept One - Wikipedia, the free encyclopedia
"The committee" says...

With a total output of 811 kW (1,088 hp) and 1,600 N·m (1,200 lb·ft) of torque, the Concept One will accelerate from 0–100 km/h (0–60 mph) in 2.8 seconds and will have an electronically limited top speed of 305 km/h (190 mph). Each wheel is powered by a separate liquid-cooled permanent magnet electric motor and controlled by the so-called "All Wheel Torque Vectoring System" that distributes the power to the wheels in accordance with user setup and driving conditions. Also, the car has the ability to switch the power from front-wheel to rear-wheel drive, the first car with that ability.

The motors are powered by a 91 kWh lithium iron phosphate battery, giving the car a range of 500 km (310 mi) per charge.

Just found this thread, and i have to say I find the design fabulous and Mate & team has done an incredible job.

good luck to them and welcome to a "new" brand of super cars !

How heavy is it? Also: traction control must cut power of P85D up to
50 mph. Perhaps up to 60 mph or even higher. Depends how sticky tires are.

From the same wiki page:
Curb weight: 1,950 kg (4,300 lb)

I don't really understand the use of LiFePO, when performance is the driving force.

 

[JRP3]

High C rates. A123's can be pushed to 40C, Tesla's NCA about 6C. The problem is going for long range/higher kWh with LiFePO4.
