Electric Corvette Breaks Streel Legal Speed Record

Go ahead and chew on this Tesla fans.
The all-electric GXE Corvette prototype from Genovation Cars just hit 186.8 mph in the Standing Mile, earning it the world record for Top Speed Street Legal Electric Car. The previous record was 177 mph, according to a Clean Technica report.
To top it off, the GXE ‘Vette pulled off its record-breaking run in full street mode, with the audio system and the AC running full blast.

The GXE, covered in an earlier reporter here, is based on a 2006 Z06 and is powered by a high-tech electrical system with 19 circuit boards that manage everything from the accelerator pedal position to the electric powertrain to regulating the Corvette’s 44 kWh lithium ion batteries.
During development, Genovation Cars said the GXE Corvette would produce more than 700 horsepower and 600 lb-ft. of torque with an estimated O – 60 mph speed in around 3 seconds.
That said, Genovation is now aiming for a 300 mph run in the Standing Mile, which would crack the Guinness record for any street legal car.

Damn, I think the Zombie 222 '68 Mustang just set that last year, and had been aiming for 200.

 

[HockmanRCBoys]

I really expected you were building a vette with a puller motor or something...i was like, "i gotta see this", lol

 

[microcrawlers]

i was disappointed not to find a corvette powered by some real hh shit

 

[4wd4ws]

It is glorious! I think I'm gonna have a heartattack... It even sounds like frikkin' Kitt.

 

[STANG KILLA SS]

well they smashed the record again. beating themselves.
205.6 mph :shock:

The Genovation Extreme Electric Car (GXE) now holds the record for the fastest land EV, breaking its own previous record for a street-legal, all-electric car. During supervised tests at the Kennedy Space Center in Florida, the car reached 205.6 miles per hour.

The International Mile Racing Association certified the record.

The car is a Corvette Z06 that puts out more than 600 horsepower and 570 pound-feet of torque, thanks to two electric motors that share a shaft. The car also has a battery pack that provides 250 kW of power to each of the car’s two inverters. The GXE Corvette has a weight distribution of nearly 50/50 and a low center of gravity.

That's pretty amazing. Congrats to them for making something awesome.

 

[CM9000]

wouldn't be able to do it without the trans haha. nice job though.

if only we could build efficient outrunners big enough lol. electric 1:1 crawlers!!!!!

no kidding. 200 mph with gasoline aint easy.
plus trying to push anything threw air that fast is like trying to run under water

 

[Robbob]

Impressive.


Also nice to see our tax dollars helped them get back to building things that the public will never get and call it research. :roll:

 

[dezfan]

That's cool.

But can they add some vrrrmm, vrrrmm sounds on the stereo. :mrgreen:

They would get more power to the ground without the transmission sapping power. If the system can push it at top speed, it can get to top speed without stepping through ratios. Tesla got rid of a multispeed gearbox for this reason. But I'm guessing the team that made this Vette has a lot more money than experience with electrics.

Sweet find "thumbsup"

can you tranlate teh 250 kw of power into something us lipo guys might understand? i have no clue what that compares too.

also was suprised at the 570 tq numbers. seemed low. or is it not that electric has lots of torque like diesel, but that all 570 lbs are available from 1 rpm?

 

[JohnRobHolmes]

yes, all the torque is from 0 rpm.


It probably has a 350 volt pack or so, which would be about 750 amps to make 250kW. I would be surprised if they didn't use igbt's. four of these would be about the right size for the task Vishay - Modules - GA400TD60S - Dual INT-A-PAK Low Profile "Half Bridge" (Standard Speed IGBT), 400 A
