Europe has new 1/4 mile record for electric dragsters – set by the “Electric Fox” in Tierp Arena, Sweden on May 6, 2016.

Driver Maris Ozolins, sponsored by Drive eO (PPIHC winner in 2015) managed a 7.631 seconds @ 171.02 mph run.  (Above video, plus more below)

The impressive result is #3 in the NEDRA overall standing (first DR/A5 class).

The special powertrain of the Electric Fox uses six pot engine electric motors from YASA!

Electric Fox dragster:
Best result 7.631 sec (top speed 275.2 km/h), mere 0.357 sec off the current electric world record.

SFI2.5C spec dragster chassis
Six YASA Motors electric motors
Six Drive eO drive controllers
Bespoke 800 V lithium ion battery pack
Peak power 1020 kW / peak torque 2160 Nm
Kerb weight 725 kg

soooo much cheaper to run than ice drag rails!

And quieter

Is it due to the cost of the fuel or some maintenance thingie?

Top fuel dragsters cost about $50,000 each time they run the quarter mile. The engine needs rebuilding and maybe the trans and rear end too? Even though this is not an apples to apples comparison it still makes the point. I imagine doing a 7 second quarter mile in an EV dragster would use about $5.00 worth of electric and the motor certainly would not need rebuilding with each pass.

So can someone provide us with typical gasoline dragster numbers for reference?

4 seconds is probably average for top fuel but they only do 1000 feet now. I do know they have done 1/4 mile in 4 seconds though.

Thanks. Well, they’ve got a lot of room to improve. I’m certain that they will. But it won’t be easy due to the weight of batteries.

Hey Mr. Cameraman, how about one video that’s not taken from directly behind the Electric Fox dragster when it goes down the track. Just a suggestion.

but ‘dat a55

3 tesla motors 502hp each with reduction gear 3-3.5 ratio will do it much much better.
If someone want can compare the torque.

Telsa gears its motor by about 10:1.

Your 3:1 with 3 motors aren’t much better until much higher speed.

Here they use YASA-400 with peak torque 360Nm and max speed 7500rpm. With those big tires they use reduction ratio 3-4 to 1.
Tesla could be used here till maximum 12000rpm.
You have to calculate the torque on the wheels after gear 4:1.
I know what is the gear box ratio in Model S, don’t worry.

Here is one Top Fuel Dragster Fact:
“Assuming all the equipment is paid off, the crew worked for free, & for once, NOTHING BLOWS UP, each run costs an estimated $1,000 per second.”
Add to this replacing the complete long block every run which is usually what happens, adds $50K+ to that $1,000 per second.
Interesting fact- Shirley Muldowney was the first person to dominate Top Fuel by sacrificing the engine on every run in order to win. Now “that” is sponsorship, it wasn’t cheap. Her valves always hit the pistons through the lights. Her little kids used to sell burnt pistons to the fans in the pits for $5 each (I wish I still had mine).

WOW
“Top Fuel engines turn approximately 540 revolutions from light to light!

* Including the burnout, the engine must only survive 900 revolutions under load.”

Not bad. I remember a few others who also went all electric. http://currenteliminator.net/ Dennis “Kilowatt” Berube and the Current Eliminator team would like to congratulate Don Garlits on his latest entry in the record books. Onboard his electric-powered SR-37 dragster on April 30, 2014 for its first full runs, Don recorded an unofficial mark of 7.26 seconds at 184.01 miles per hour and an official record of 7.526 seconds at 178.42 miles per hour. 2014 marks 50 years since Mr. Garlits broke the 200 mph barrier in 1964. Now his team is set on making him the first to eclipse that mark on battery power. Best of luck, Don! Christmas 2007 came a few days late for Dennis “Kilowatt” Berube, but he couldn’t be happier. Rewarding Dennis for all his hard work on Current Eliminator V, Santa Claus delivered a new world record! Catapulted by its new Altairnano lithium-titanate batteries, Dennis piloted the dragster to a new, official time of 7.956 seconds at 159.85 miles per hour. It was Sunday, December 30th at Southwestern International Raceway in Tucson, Arizona. Having just set a new, unofficial record two weeks earlier, all eyes were on Dennis Berube as he shaved time off… Read more »

Dennis Berube has made more than 10,000 all-electric runs. Far more than anyone else. Now living in Thailand and still drag racing.

I like the 800 V although 1600 V would be even better. More bang is always good. Less wire losses, denser windings, with denser magnetic fields. More possibilities, less weight, less costs. It all adds up. What are we still doing with that low 400 V. Sure it works and so would 24 V but it is so conservative in regard to what could be. The wires should essentially be insulation instead of essentially metal.

Top fuelers can run under five second quarter miles at over 300 mph. Top fuelers also generate over 3,000 hp, about 2 megaWatts. Electric cars still have a long way to go to compete with top fuelers but it’s good to see them try.

Sorry, todays top fuel cars actually have 11,000 hp, AVL made a special coupler to measure the torque – see

Drag racing’s Godfather – “Big Daddy” Don Garlits, is still around. After revolutionizing drag racing in the 60’s by moving the engine to the rear, he now is playing with electric drag racing.

I found it interesting that drag racing – with its roots here in the US – is the sport area that Europe has to use “feet” and “miles” to measure things with.
