The Car Thread ... !

Netherlands?

It is a very exotic car/engine combination.

Most of these sporty 3 Wheeler are powered from Citroën Boxer Engines or moto guzzi V2 Engines.
Most of them has been built by Lomax and Burton , Morgan came back in 2012.

But I guess it’s something much rarer.
 
nope nothing from the netherlands :)

indeed it's quite rare today with less than 100 thought to still exist of the Model im buying, but they were quite popular at one point in time

they came from the factory with a Halon fire extinguisher

theres a couple more clues for you :)

Gearbox and Engine?

I remember in the 60‘s Cars with 3 wheels could be driven without Car licenses therefore they were very popular.

as in the Gearbox was made by the same company that built the car :) (and they supplied gearboxes to the second company who built the cars as well)

im very excited be posting in this thread that after a lot of effort, a good year of searching and saving up, a deposit has been made on my first car! im very excited about it all as car enthusiast to be getting my first car is quite an event for me, especially as its car I have a lot of enthusiasm for :)

ill give a few clues and see if anyone can guess what it is? :)

its a car that was designed and built by a famous sports car manufacture, it has a hemihead all aluminum engine, fully independent front and rear coil over suspension with gas adjustable shock absorbers and its a 2 door :)

This confuses me a little bit.
The only famous british sports car manufacturer, who built 3 wheeled cars was/is Morgan.


Aston Martin : No
Ginetta:No
Jensen:No
Austin Healey: No
Jaguar: No
Marcos:No
TVR: No
Daimler: No
Lotus: No
Bentley : No
Reliant:Yes but they used always straight 4 engines.

Bond Cars made 3W Cars but with 1 cylinder Engines, the later Bond Bug was again straight 4.

Lomax made proper 3W cars with Boxer engines but otherwise they had no history in Sportscar manufacturing.

There’s Triking Motors but they used always v2 engines.

It’s possible that I already saw your car somewhere in one the magazines I subscribed but simply can’t remember.

Something tells me you're not very smart. So people who bought a McLaren or Ferrari's hybrid supercars are idiots, yes? People who bought the latest round of Mercedes vehicles with a co-engine are stupid, yes?

Problem with electric cars at the moment and the foreseeable future is how hot the batteries get. I've posted about this once or twice in here, but I drove a Model S P100D around very basic twisties near work and it quickly heated up. The beauty of a well maintained ICE engine is that it won't heat up without considerable heat via weather. FWIW, the day I drove that Model S it was fairly cold for the coastline, about 40-43* F. I cannot fathom what type of temperatures the pack would experience in a typical summer much more inland where it goes well past 100* F. That's a 60 degree difference.

Wouldn't put my own kids in a Tesla as I have zero faith in Tesla's build quality. Now, had you read anything before posting, you would have attempted to understand what I said. What's bad about a co-effort setup? It isn't new. It's been done. It works. It's developed from race tech.

Just curious, but how did you measure the temperature of the battery?

Yes, I think they are stupid for buying a hybrid supercar. I love the looks of the Ferrari, but you do know the one (and I don't know which model) that they advertise as partial electric only gets 15 miles on that electric part, right?

Tesla's build? seeing as how they get a perfect safety rating by consumer reports, I'm thinking you just have a bias against Tesla that doesn't allow you to appreciate how safe they truly are.

 
I am really curious.

Especially as I know a lot of British sportscar manufacturer and it’s none of them.

I am really surprised about it.

Also it’s Engine is very unusual: Most famous flat 2 were made by BMW, citroen , Panhard, Daf, Steyr.

2 Wheels ahead ?

This was driving me crazy for a full five minutes, so I did some advanced Googling and I'm confident I found it. I kinda cheated, so I don't want to ruin the game (this sounds suspicious, doesn't it?).

It does explain all of the clues, so I'll sleep well tonight. I can say though that I have heard of the brand before and while I couldn't figure it out myself, I'm surprised it hasn't come up yet.

Anyway congrats on the car! :D

haha Thanks :) yeah Im wondering if anyone can guess what im getting without googling all the clues! :)

(although id not be surprised if most people have resorted to google at this point!)

If you've owned your Tesla long enough you'll know the battery system goes into thermal protection mode like any other electronics system. Even a vacuum has a thermal switch to prevent overheat of the internal components. A Tesla is no different in that regard, nor is an ICE vehicle. Except an ICE vehicle has more room to breathe. In other words, the power became heavily throttled. You might argue this is no realistic case because the majority of Tesla drivers won't be driving their car on backroads twists and pulls. True, except neither would most if not all cars, yet nearly all modern cars can easily get up to 140 MPH.

The Model 3 supposedly uses a much newer cooling system and I'd like to try that out. The Model S and X supposedly share very similar cooling systems, and thus both are prone to battery overheat causing the car to throttle power delivery until the cooling system cools the battery packs to a sufficient degree to not cause the vehicle problems. Batteries overheat during charging and high drain use. Casually cruising along a highway won't cause thermal issues. Driving the way I did would, but it shows a flaw in electric cars, specific to the Model S, at this time. There's been a few videos by YouTubers claiming the opposite, except they tested in the dead of night during the end of winter when temps still linger around aught. Though I'd be curious to see if the fan system for the battery is in high gear at that point. There are easier ways to cool the system from a laymen's approach. The use of heat transfer pipes and cooled directly by passing air is rudimentary but it would work. You do bring the issue of corrosion of said heat pipes into play, though.

Then again, the Model S was never designed to be a sports sedan. I'd be interested to know if the new upcoming Roadster can avoid this issue. However, this doesn't fix the other issues Teslas been having for several years now. This also doesn't include the car not having the pizzazz it did on a fresh charge after horsing around.

At the roadsters estimated price point and the problems it may have down the line, it would be cheaper to pick up a 991 Turbo S CPO and use that. Launches to 60 in 2.5 and you can do it all day without damaging the PDK. Or simply wait for the next 992 Turbo S.


40-45*F is fairly normal for the coastline of California. It does get much colder elsewhere, but you'll be at a much higher attitude. We do have nights where it may drop down to 28* even at sea level, but they're rare. Spring begins at around 75*F and summers top out at 115* as a rare event, but usually hover around 105*. I dread to think of performance issues with a Model S then.

The Panamera uses a 135 HP 280 ft lb torque motor in conjunction with the petrol engine. Do you think that's stupid? I think you hold a severe bias as a Tesla owner.

Consumer Reports downgraded the Model 3 due to concerns over its reliability. Tesla manufacturing quality control is a joke, even years later. CR as a guideline is an interesting proposition because they will recommend or not recommend something based on various factors, and are known for removing recommendation or simply not recommending products based on their internal criteria. That said, the problems Teslas have are wide ranging and well known.

EVs aren't for everyone. I certainly wouldn't pay close to $100,000 for a tricked out Model S only for its NVH to be incredibly noticeable whereas a comparable car is nearly silent inside. And that's before the other flaws show up.

I'd be more inclined to buy a Taycan than a Model S. Because I know the former isn't rubbish. I think you're being too emotional because you've bought the product and want it to be the best thing since sliced bread, except reality doesn't play out like that.

Plus, Tesla's drive units tend to fail at regular intervals.

The Model S uses the battery pack as a heat sink, but heat soak is easy to achieve if you really know how to push a vehicle to its limits without breaking ground contact.

Where are you getting this data on drive units failing? How old is that? I'll do my own investigation and get back on my sources. Please post yours.

You do realize that the battery pack uses fluid that goes through it like lasagna to cool/heat the battery, right? It's not a "heat sink" like you suggest. I think your data is either out of date or just made up....please bring sources.

Rather long, but I tend to trust guys with PhD behind their names...

You get the best performance from a car with an electric powertrain for the instant torque and an ICE engine to pick up the slack when things are already moving.

The Tesla has a hell of a start off the line but the C63 catches up and passes it. If you took the two powertrains and combined them, my god...

Plus you avoid the too clinical, all electric drivetrain as a bonus. A good exhaust note is just oh so satisfying.

I love the silent approach, but that's me.

Not sure what you mean by "too clinical"? Do you mean, none of the potential faulty parts that propel an ICE vehicle? The drivetrain on any ICE vehicle is one of it's weakest points.

Cross query Tesla Motors web forums and enthusiast sites. Drive unit failures are not a thing of the past. Tesla would never release data on their drive unit failures since they replace it themselves. They replace everything themselves. It isn't good for Tesla is they indicate they have issues with drive units failing or other serious issues that cause customers to turn their vehicles in for repair.


I'm more inclined to believe people who post about their cars needing work done or the issues they face with Tesla acknowledging there is a problem.

Is the fluid moving hot liquid to be cooled by fans? That's a heatsink. In the same language, an AiO cooler still uses a massive copper plate to remove heat from a heat source and on the other side fluid travels to radiator fans.


To quote this site:

https://avidtp.com/what-is-the-best-cooling-system-for-electric-vehicle-battery-packs/

The Tesla models S battery cooling system consists of a patented serpentine cooling pipe that winds through the battery pack and carries a flow of water-glycol coolant, thermal contact with the cells is through their sides by thermal transfer material. Again this will remove heat from the side of the cells rather than from the tabs, and overheating a Tesla battery pack under hard driving is easy to do.

This in basic English is cooling pipes which direct water glycol mixture (this is to prevent freezing, it is essentially anti-freeze) through a series of pipes that make contact with the battery packs using a thermal transfer material.

That is fancy talk for a thermal pad or sticky paste. It's likely to be a similar compound to CPU compounds. High end electronics equipment in the compute segments may have VRMs that reach 90C. Most high end mosfets in electronics including cars can hit 150C without issue and still function normally. Both those figures are far higher than what battery packs are able to handle comfortably. Sticky pastes are synthetic materials that allow heat transfer to occur. This is basic thermodynamics. Liquid metal also exists.

Tesla cooling isn't special. Your video discusses the ability to make more compact, energy dense batteries over what was possible decades ago.


Edit: Your lasagna comment got me intrigued. So I looked it up. Basically, they may use a thermal compound, but it's an aluminum wave sheet with tiny channels allowing liquid to flow through. This is a heatsink. The aluminum sheets are the heatsink, the channeling within that moves water makes the the car's system an AiO cooler. Ideally, they could have used copper since it's better for heat dissipation, but it adds more weight and much more cost. The cooling design Tesla uses is new and unique, but the theory in which the packs are cooled is old tech. Ideally, Tesla would be better off designing a cooling liquid that can allow batteries to be submerged and draw coolant through piping and cooling it off using intaked air and the cabin cooling system. Because of the way metal is machined, I'm almost certain some synthetic is used to allow for a better contact patch with the "lasagna' fins with the channels for better heat dissipation. The idea of a non-conductive fluid is good, but weight and replacement becomes a concern. It would cost more to repair batteries and increases waste in the long term.
