RWD Tesla Model S P85 Hacked To Put Out 589 HP – Video


Jason Hughes is known is Tesla circles as “the guy with the yellow Tesla Model S” or the “Tesla hacker.” He has been working on a hack to convert his P85 to rear-wheel drive, and beef up the horsepower.

Everything worked out for him and he shared the video to prove it. Hughes has said that he may offer his expertise to anyone that would like him to hack their cars. We’re pretty sure it’s not the best idea …

The P85 that Hughes is working with has retrofitted Autopilot hardware, and upgraded P85D Ludicrous battery pack. It’s also running P85D firmware. The car doesn’t have a front motor, but a hardware/software emulation “tricks” it into thinking that it does, and tells the car to send all of the power to the rear tires.

Hughes says that the car could definitely use some wide rear tires, and he has been up against colder temps and wet conditions, and has yet to run a perfect test with 100 percent charge. Nevertheless, he gets a 3.48 second zero to 60 time with the 589-horsepower Model S.

He’s posting details and results on the TMC Forum and his Twitter handle is listed there as well.

Video Description via Jason Hughes on YouTube:

So, I finally got around to trying a crazy idea about getting more power out of our RWD P85…. P85 Ludicrous….. and have been successful. 🙂

589 HP RWD Tesla. Definitely the most powerful rear-wheel drive Tesla ever.

The day has finally come when people start to “Root” or jailbreak their cars to get more features. I could definitely get into this if i was out of warranty.

Hats off to Jason for his Tesla hacking skills and the willingness to share what he learns!
As much as I like Tesla, I’m against their closed service that doesn’t provide service manuals unless the law compels them to, such as in Massachusetts.
I’ve repaired many of my cars over the years and the ability to get service information was never a problem. Until now.

Anybody can get the Tesla service manuals.

They aren’t free, if that is what you are getting at. Then again, I don’t know of any luxury car maker that just hands over their service manuals for free either.

What exactly is your complaint? That you don’t know where to get the service manual? That you don’t know how to type “tesla service manual” into a search engine? That you like repeating 3 year old memes that aren’t true, but will never die?

That the only state that shows up in the tesla service manual location dropdown is Massachusetts.

I guess you missed all of these PAY options:

North America
United States
Asia Pacific
China 中国
UK Deutschland
Belgique België
France Sverige
Italia Nederland
Norge Österreich
Danmark Schweiz
Svizzera Suisse
Luxembourg Europe (English)

Yeah. Let’s let hackers do anything they want to cars. Tesla should cancel his car warranty for making an unauthorized modification that will reduce reliability. He voided the warranty.

That’s know in the automotive world as hot rodding and owners have been modifying their cars (and voiding warranties) since the car was created.

That car has been “out of warranty” for a long, long time….

only if the claimed warrantied failure can be shown to have been caused by the modifications

I see you are unfamiliar with the multi-Billion dollar automotive aftermarket industry…

Ha! I bought one of those kinds of ‘Out of Warranty’ Cars – way back in 1984! it was a 1983 Mazda RX7 GSL-SE, with Aftermarket Arkay Turbo, rated for 205 Hp (versus the Stock 100 Hp!)!

Performance Numbers? Never took it to a full race track, as I did not know of any at the time, but I still found a way to discover its performance: Redline in 1st through 5th – No Problem! Cruise at 200 Kph (125 Mph) – Comfortable! Top Speed: 215 Kph (135 Mph)!
Price – $19,000 + tax!

Drove 30,000 Kms (~20,000 Miles) [Quite a bit of it hard] in 1st 3 Months, Overheated and warped Apex Seals (which then split in front rotor Housing, causing all kinds of unfriendly sounds, and an engine that needed 2,500 Rpm to stay running! Payments: $670.00 a Month, Wages $12.34/Hr! (Inflation adjusted to 2015, Canada: Payment: $1,399.70 – Wages: $25.78 –

“Convert to rear wheel drive”?

His car has always been rear wheel drive. He “converted” the firmware from another model to work on his car.

Saw that and maybe it’s a typo to convert to AWD

You can’t convert a 2WD car to AWD car without adding a motor. I agree with Doggydogworld, probably meant to say converted AWD software to RWD.

Yup, and he’s tricking it to send the power to the rear wheels. I’m wondering if he is fooling the computer into believing the front wheels have lost traction, so it is transferring power to the rear wheels all the time?

Thank you! That makes sense.

The article must be wrong.

If I cannot see it drifting around a track I do not care much

It’s great to see that there is one guy doing to a Model S what used to be done by hot-rodders everywhere, back in the days of cars with carburetors.

And sad that there’s only one guy doing this. 🙁

All the electronics in modern cars make it very difficult to “hot rod” a car, or make other significant modifications to the powertrain.

Hopefully anyone who contemplates doing something similar to their Tesla car (or pretty much any car, for that matter) realizes that this will void the warranty.
