An improvement of 0.61 seconds - 12.3% - was better than I expected. With a full battery, and maybe without a passenger, that improvement would have been even greater. Thanks to both of you for performing the tests, 🙂👍
I'm also curious. I read about some sensors online and they combine 3-axis gyros, accelerometers and magnetometers - so perhaps that also comes into aid for traction control? Particularly accelerometer. Think "at what speed computer sees wheels spinning versus the inertia felt by accelerometer" - this would also explain how it's so instant as accelerometer gets immediate feedback from inertia. Accelerometer however can't tell the speed so GPS aids for corrections at high speed which still makes your question relevant. My assumptions though.
What's the chances of needing TC when you're already moving? Unless there's standing water in there and you aquaplane, but if you come to a stop in a tunnel, then it'd probably be traffic related, not going to gun it away there.. Also wondered tho
My childhood wall poster transformed into an electric?! EGAD!!!! But, holy cow is this amazing! I almost want to hunt for an old Ferrari now and build! Just a beautiful result and I love the Red Head's NA 12 cylinder. I loved the one I saw in person in 1989, I love the Miami Vice one, I love the models I have. I love everything about the Testarossa. This though, this is epic! Off to binge the whole series.
I suspect that by the time that Rich has sprinkled some magic dust on the power management system, the Teslarossa will be closer to 3 seconds for 0-60 mph
@@neilmckechnie6638 remember tho, his Defender is AWD....and it's punching out 600hp. Both vehicles are around the same weight too, which is interesting. Also, keep in mind that traction control cuts power (momentarily) on and off to limit wheel spin. There might be some time lost there, even tho it's faster than no TC on a RWD vehicle. The acceleration ramp looked a little soft too, but that can be adjusted. I'm not sure if the Defender has TC or he is just relying on the AWD grip. I'm guessing once the suspension is sorted it will help with weight transfer and a little more tuning might get it down to below 4
I am hoping you can covert a newish cayman one day but with a very small battery pack to maximise power to weight.maybe it could have a secondary remove able battery pack to take out at the track ... great videos guys
Why not just compare the speed of rotation of the front wheels versus the rear wheels ? A lot cheaper safer and simpler, since in town there are places where GPS will often drop out.
I have the same concerns about GPS. What happens in a tunnel, or a city full of skyscrapers? As for why not use wheel sensors, I'm going to guess it is a lot simpler to retro fit the GPS version to a car than it is to add rotational sensors to each wheel.
I doubt the Ferrari had ABS so it won't have wheel speed sensors. Much easier to fit a GPS system. Cant see any sensible person needing traction control in a built up area!
A great show, look forward to seeing the suspension updates and track test. Is this really using only GPS to control the torque or does it make use of an onboard accelerometer as well? What happens in say, poor weather with weak GPS signal or areas where the GPS signal is weaker due to buildings, tunnels etc?
That is a gorgeous dam, oh, and the car is nice too 😉 I'm surprised by how well the GPS traction control works. "Even an idiot can do it now" is an excellent stamp of approval!
I am stuck in the middle as a through and through petrolhead and can't get my head around taking the engine out of a ferrari, but at the same time I am very impressed by your work
Awesome video. Can you provide some more of the technical details in a future video? Is this something that is doable/affordable by someone doing a more basic conversion say on a classic VW?
The car is amazing and the traction control seems to work great but what wold happen in an area with no GPS connection? Where I live it can be pretty patchy.
I'm sure others have asked you this, but have you considered converting a Citroën DS with a Tesla motor? Others have done it with a HyPer9 motor but that retains the gearbox.
Richard, Greatly enjoy the channel, and I love the depth of engineering knowhow shown by you and your team. I do have one small gripe, though.... Given that you have acknowledged that Traction Control is not just a performance enhancer, but also provides safety, I do not agree with using just GPS for this function on the TeslaRossa. You must have spent quite a bit of money on this car, and as such, I would have thought that fitting speed sensors on the wheels would have been a worthwhile investment. This car has tremendous torque and power - what if you hit an oil slick inside of a long tunnel ? (We have quite a few of those even here in Australia) - Just think of the massive pile up it would create..... Food for thought? Ron
One of my concerns with GPS traction control is well the GPS aspect and how unreliable the GPS signal can be at times, GPS signals can be lost or degraded if you are in a populated area like cities or if you go in a tunnel
I love the idea of an electrified Ferrari. I would not rely on GPS for traction control. It may work OK in the open Wild West of Wales with just sheep for company but the signal will disappear in tunnels and driving through forests or built up areas you will get multi path reflections that could make the instantaneous speed measurement jump all over the place.
I tried a GPS speedo many years ago. The results weren’t good. So far the GPS traction control system has been faultless. Something must be fundamentally different between the two.
Are you inviting The Stig to your track test😆. That looked painful during those runs but the rate of acceleration doesn't really come across in the video. It almost looked like quite a delay from your right leg planting the throttle and the scenery starting to move outside the window? You should get a G-Meter hooked up, see what the forces are? Still very impressive to watch though and, as others have commented, Wales was looking splendid.
So I ask what do you use in VW Bug & Crewcab/Buffy in regards to Traction, is it GPS cause of the Tesla Gear ?, I was wondering as it seems a nice option, to turn it off, to warm up the tires a bit, then switch it on for the "Race", or Demo .. ;), Maybe you should do a Lap around Nuremberg with it, Before Delivery, just to make Mercedes Drivers Weep, OOps, I mean to test out its function at speed ..
Actually, no need to even sit in the car. Put a camera in the car, sit at home, and drive it just like a playstation in real time! You can use it for delivery purposes.
it was 3.99 sec 🤔 w/o traction.. & King Richard of ECC😊 ..his Majesty was alone but now it is 4.35sec ? with gizmo.😮..guess the 'phone holder ' has got to go...😅..its all about balance and weight😂..
Really shows how limiting it is to have just two driven wheels. There are any number of AWD electric SUVs doing 3 seconds or even less. But yeah, for a RWD EV to get into the 4s is pretty fast!
Are you going to post who makes this GPS based traction control. Does the traction control do so by changing the 0-5vdc signal of the accelerator pedal or does it directly control the inverter. My inverter control acuity is every 2 mili-seconds.
Re living back to the future with that 1st burn out even the electric noise gave it atmosphere 👍with the GPS system is it plug in a play?or countless hours of wiring it in?
