Go ahead and google my post... I don't copy-paste without using the quote tags.
Tesla licensed the entire Elise bodyshell and suspension from Lotus. It was a cost-saving measure on their part. It's something that many electric start-ups are doing now to bring their electric cars in under cost. Sadly... they're still expensive. The Phoenix SUT... based on the Ssangyong Actyon... still at a projected $40k. The Electrovaya Maya... based on the Chana Benni... still at a projected $20-30k (and the Benni is only worth about $7k-$10k)... the Xap Zebra... based on a Shangdong 3-wheeler... $16k in the US... available in China for only $3k... as an electric, to boot.
If you're serious about producing or home-building an electric... You can look at how these people did it for an idea on how to control cost and get results.
It's not just the weight. It's the batteries. If they'd included enough batteries to achieve the range they were quoting, the Tesla would weigh way too much.
Well, the investors wants this and that, eventually adding to the weight. Using Li-ion batteries solved the problem in part, but not all.
Really? That's interesting. The Fetish project is older than the Tesla, and their body is bespoke... which is probably why the price was so staggeringly high.
What you see now are all related. Design, working relationship, etc...
To keep costs down, use a pre-existing platform... then you can concentrate on working on the electric motor controllers and battery layout.
They did resolve that part, doesn't mean its perfect, but it works.
You should try to watch Top Gear Australia's electric car challenge. They basically built two electric cars in their garage. One presenter was quite successful... what he did was place a huge surplus electric motor in front, tons of batteries in the back, then linked the system straight to the driveshaft.
The other guy had the brilliant idea of linking electric drill motors to a planetary gear, then he bolted the whole thing to the transmission (front drive car)... it was too complicated, and broke... but the idea is sound... if you can create a more robust linkage between the drill motors (strip the casing and create a new steel casing to hold them against the planetary gear), you'll have a relatively powerful motor for not much money... and it'll already have speed controllers and a throttle attached to it. Five or six drills should do it...
