Aspark's EV does 0 to 60 in under 2 seconds

Aspark's EV does 0 to 60 in under 2 seconds

Taking center stage in EV news is the Aspark Owl, an electric supercar that does 0-60 in under 2 seconds (just know that the record was set on racing slicks).

Aspark's high-style supercar just "blitzed the benchmark run" as TopGear.com put it, during a recent test carried out in a tiny parking lot.

Viknesh Vijayenthiran in MotorAuthority along with other car-watching sites, said it managed to accelerate from 0-62 mph in 1.92 seconds.

That sent up many "Wow" signals.

Vijayenthiran said, "Powering its is a combination of batteries and supercapacitors, said to be capable of delivering a range of 93 miles on a single charge."

(TopGear.com added that "Aspark reckons this Owl is capable of hitting 174mph flat out, a top speed that would likely affect the claimed 93-mile battery range.")

The Owl first got attention last year during the 2017 Frankfurt auto show. It's an "electric supercar" from Japan. InsideEVs said it packs "some serious" technology.

The powertrain is all electric. TopGear.com said "the Owl runs a pair of 40kW motors, offering up 429bhp and 563lb ft of torque."

The Owl weighs 1,874 pounds and InsideEVs noted it had all-carbon bodywork.

TopGear.com called it a "two-seat, butterfly-doored exotic."

Vijayenthiran turned to availability and price: "Unfortunately, Aspark only intends on building 50 examples of the Owl, each priced from a staggering $4.4 million."

One key question, then, is how this sleek car might impact the next-gen Tesla Roadster's future.

The Electrek in November last year said, "The battery pack powers three electric motors unleashing enough power to achieve a 0 to 60 mph time of 1.9 seconds – the quickest of any production car ever."

So is the Owl to be faster than the Roadster? "On slicks, maybe. But on road tires the Tesla Roadster likely still reigns supreme." That was the comment from InsideEVs

Several news sites pointed to the tires on Owl during the test. The tires used were Hoosier racing slicks, not street-legal ones with rain-tolerant tread grooves, said Motor Trend.

Reports said the company wants to repeat the test with road-approved tires.

Well, Joel Stocksdale, an associate editor at Autoblog, had some thoughts. Shots of the speedometer? Time or speed recording displays? Also, "the location seems oddly small to be hustling a car to about 60 mph and back down. It looks like a parking lot behind a warehouse, and though the claimed times would maybe make the feat feasible, we'd be nervous going that fast in a short parking lot that ends in a grassy upward hill."

On the other hand, Stocksdale wrote that "we can tell the thing launches really hard. So overall, we're cautiously optimistic about the Owl, and if the company keeps rolling out info and video like this, the ratio of caution to optimism will probably shift to optimism's favor."

""the Owl runs a pair of 40kW motors, offering up 429bhp and 563lb ft of torque.""


That doesn't add up, since 40+40 kW is just 109 bhp.

But maybe that's the point. Electric motors can be overdriven by a huge margin, limited by overheating, so the stated acceleration can be achieved - for not much longer than the 2 seconds.

The engines would still run at a quite high efficiency if overdriven by that much so the heat would be the least problem for the "engine", the power supply on the other hand which goes hand in hand with the very short range this car would achieve when going full power.. 35? 50? miles..? Even 100 miles (less than the specs) is too less.

No question that electric motors are superior in all ways to internal combustion. The problem of course is the energy supply system. Batteries suck and until they get better batteries (cheap, fast recharging and long range), electric cars will remain a niche market.

The tires set the limit. No matter how much HP you have, if the tires slip, you don't go. A Tesla could accelerate faster on Hoosier slicks.

My friends, this appears just a drag racing car. Of course it is easy to have a fast drag racing car with small high discharge batteries and overdriven electric motors. People have built something with similar performance from old Civics 10 years ago. But can you drive in it to buy kitty litter 100 miles away?

Plus it is batman ugly, for $4.4 mil. No competition to Tesla, sadly.

"The engines would still run at a quite high efficiency if overdriven by that much "


The losses increase at the square of current, so if you push four times the rated current through, you get 16 times the waste heat. If the efficiency at the rated full power was 95% meaning that 4 kW was being lost to heat - which is manageable - at the full overdrive it would be 64 kW which will burn the motor insulators pretty quickly.

That's why more powerful motors need to be built bigger with more elaborate cooling systems. With size however comes rotational mass, which limits the acceleration because you're spending energy to get the thing to spin in the first place - a great deal of the motor's power goes to just fighting the rotational inertia of the drivetrain.

So if you have a tiny motor that can be overdriven by a huge margin, for just long enough to get you up to speed, you can achieve very high accelerations.
