Must admit I was surprised that Tesla just bolted together a load of 18650 cells into rectangular boxes - feels like a prototype way of getting a battery together. I saw a couple of TV programs on BMW making the i8/i3 and it shows the batteries being "folded" from very thin strips that make proper rectangular batteries (like you get in cell phones), this will increase energy density over the 18650 (imagine a load of AAs next to each other, there's plenty of air between them because they are cylindrical). It hinted that BMW might be manufacturing the batteries in their own plant, not sure if they are but they have definitely in-sourced the e-motor manufacturing. The thing with Tesla is that they could probably go for the better batteries quite easily (maybe they've already started making them). The rest of the car however: balance, fit and finish, safety, comfort, handling, refinement, image etc... are things that other companies have been perfecting for 100+ years.

Here are Youtubes showing the batteries of the Telsa. The technology of 1990.

Mine gave birth to a 991 Turbo S and GT3. Pretty stoked that the i8 could do this.

I have a Tesla Model X and I have my dealers 1st allocation on an i8 Roadster. I also had a Chevy Volt before the Tesla.
The i8 is not a very practical "electric vehicle" or hybrid... It just cant compete with any of the current Tesla vehicles. If I could only have a single EV, it would certainly be the Tesla. The i8 Roadster will be replacing my M6 Convertible as my low mileage summer weekend car. The i8 is interesting and fun, but it is nowhere as functional as a ModelX, ModelS, or Model3. The fit and finish on my BMW's is a little better than the Tesla, but what good is an EV that has no practical range or usefulness? (...other than a summer weekend "toy" car...)

Did they change the color of the background of that odd "Roadster" B-pillar logo? It seems to look darker and a bit more acceptable on the Detroit car than it has previously. Agree on the disappointing tech upgrades. I really had hoped BMW would have put more into the i8 than what they seem to be delivering. Any word on price yet?

Tesla does have a lifestyle niche/demographic despite being rim bendingly overweight, not very agile. They know how to market and stay ahead of the perceived development curve which is an advantage over many other car companies (Mitsubishi i-MIEV anyone?). |

Tesla don't sell the handling, only the 0-60 times and range, that's good enough for most people who want into an EV and smoke everyone away from the lights. Tesla wouldn't have used 18650s if weight/handling was a major feature, each little cell even has a metal casing adding weight! The foldable lipo battery tech has been around since well before Tesla cars and definitely improves energy density. Having said that, I don't know what they're doing at the giga factory, hopefully not re-packaging 18650s from LG! Future battery tech will have structural parts of the car forming the battery (bits of chassis or even bodywork), then we're into a proper revolution

About 8:40 into the video, you can see how BMW make the cells for their batteries and how much bigger and space efficient they are than Tesla's 18650 cells.

According to Autocar the i3 and i8 are history, so yes you'll be shopping around shortly. BMW i3 and i8 might not be replaced https://www.autocar.co.uk/car-news/i...ot-be-replaced

Fact is the i8 really only has one thing going for it, and that's the "cool" factor. At the end of the day it's a 170k confused car that gets you 34 miles electronically and runs a 4.4 0-60. Please stop being a fanboy. |

As for Tesla, it entered a space that was just gearing up. It attracted a cult of loyal drivers who ignore its ugly and bland design, heavy weight, the need to find a supercharger to have reasonable charging times, poor build quality, and ergonomics that are a worldwide joke. Oh, and did I mention its battery technology is from 1990 and every other manufacturer that is entering the space will leapfrog its technology by 2020. I'm not the fanboi.

https://blog.caranddriver.com/new-te...20-mile-range/ You can go on and on about battery tech and this and that but it really doesn't matter. Fact is that Tesla has electric cars NOW that people actually want to buy and drive. BMW, not so much. BMW is being left in the dust in so many ways...

The Tesla Roadster doesn't exist. It's an aspirational car. Tesla is having trouble making its touted bread and butter car, the Model X. 90% of them fail QC after going through the assembly line. And they're being pumped out at a fraction of their planned production. And at double the promised price.
Tesla has to get its sh!t together before it can think of yet another model or the truck. And by the time that happens everyone will have leapfrogged it.

Wowsers, maybe I should cash in my Tesla stock...
And when did the MSRP of the i8 get bumped up to 170k? And 0-60 slowed to 4.4? [maybe unreleased new facts for 2019 roadster?] And how does all of this relate to the thread topic of the Detroit auto show update???

Plus the car handles better, looks infinitely better, weighs less, and you won’t have range anxiety. Which car is better depends on what you care about, and for me handling, range, looks outweigh being a second faster going to 60. |
