Any proof for this silly conjecture? Lotus knows how to make a car chassis

People like you are a big problem. Heavy is by no means better when it comes to a car. A lighter car handles better, accelerates better, stops better, and gets better gas milage. With a little engineering talent, they're just as safe or safer than heavy cars. Look at the genius coming out of Hethel, England (Lotus): an epoxy-bonded aluminum chasis. Do you think old-school GM would have ever used epoxy to hold a car together? It works quite well. The only trouble with the Elise, though, is that it doesn't conform to the 5mph bumper regulation, but that's just a detail in the end that can be solved with actually having bumpers.

By the way, I've got an idea in development that can reduce a car's weight by perhaps a factor of 10 while still maintaining crash safety.

That and every new driver, college kid, hippy would at least consider it.
How is that even possible?:confused: You basically said, if they would make a "cheapo version of it... without actually changing anything".

that's all fine and dandy, but what I want to know is the lifetime of those batteries and how much they weigh.

also from the looks of it, the car may not have a brake force recharging unit like on the prius, definitely a no-no.

Obviously, but SophalotJack described it like he wanted Tesla to release an expensive and cheap "cut-down" SKU at the same time... Then went on to state that everything in the expensive SKU would also be in the cheap SKU.

I'm not saying that heavy cars are better, the car giants are. I prefer a lighter car that handles better. Generally speaking, a *cheap*, lightweight, and safe car body is not possible, and that's the trick to making this car enticing. Add the standard equipment for a car today, and this concept is further thrashed. I'm not saying electric cars are bad ideas, I'm just saying that peoples heads are in the clouds.

I don't want to reveal my idea to the public yet, but let me just say that it's possible to do it cheaply. I don't know how you can trust me, but frankly I'm not asking you to... at least until the product is ready for the streets

Marshmellow body panels? Soft, safe, and a fun treat for the whole family when the car goes up in flames!

Nice, but it's not a Pinto.

well whatever your idea is, make something of it... don't let it go and have it turn into bullet-ball:laugh:

dude.... did you a actually look at the pics of the car? I mean.... not to be a tredby slang tosser... but "lolomgzwt!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1"

That "car" can be tuned down for the av US citizen,,,, son.

don't be dumbtard fvck up.... this car is 100% affordable to non-hippy phagtard cali h0m0s

Making a cheaper car isn't all that hard. Just look at the differences between the Camaro Z28 and the Corvette. The Z28 was quite a capable poor-man's Corvette.

Look at that car, it's a sports car.

I am sure they can cut corners on the suspension, body parts, interior bells and whistles... and the whole convertible thing.

They can do all that and still have the same safety and performance.

If you're gonna get a supercar, GET a supercar. If I was rich, I would own (at least) two vehicles: An extreme eco-friendly car (like the Aptera that gets 300mpg) and an extreme sports car (like an Ariel Atom, a Lotus Exige, or something home-built that can smoke a Ferrari)

The website says it takes 3.5 hours to fully charge it. If I had the money and the smarts I would design an electric car that doesn't even need to be charged. I would design the car so that the car would charge itself when the wheels are spinning. I'm suprised nobody has come up with something like that yet.

A generator on the axles would cause extra drag on the motor, which would cause the motor to work extra hard just to keep the car moving. You would end up using more electricity just to keep the car moving then you would get charging the batteries with the spinning wheels.

There is no free lunch. You can't get more energy out of a system then you put into it. Hybrids already have a regenerative system on the brakes that charges the batteries when the car is slowing down. In that case, the drag caused by the generator is OK, since you're trying to slow down anyway. But even with the hybrid systems, you are adding energy to the system (car) in the form of gasoline.

Perpetual motion, FTL.

edit: I think MercenaryForHire put it little more succinctly then I did.

Instead of relying on plugging it in to a wall outlet to charge. Why don't they integrate a small (think 400cc) diesel engine to provide the power to the car. The weight of the engine can be offset by having a less amount of batteries in the car.

Look at the hybrids already on the market. See what kind of performance and mileage they get from a 1.5+ liter engine and motor.

Adding gasoline or diesel to the car defeats the purpose of having an all electric system. By having to plug the car into the grid, you're moving energy consumption to the power plants, which are more efficient and can be better regulated. Ideally, the power plants would generate electricity using a cleaner fuel source, like nuclear, wind, water, etc.

The real argument should be, over the lifetime of the vehicle from manufacturing to recycle, which uses more energy? An all electric or all gasoline system?

Electric cars typically have a greater city range than highway.

Only with brake regeneration....
