What I want to know is if there is anyone interested in putting down a deposit down for a Tesla Roadster. Group buy anyone ? 🙂

This is one amazing car. That flat torque "curve" is what turns me on.

Buying a Tesla Roadster is sort of like Buying an Eclipse E500.

[quote=esmith]is it really that difficult to simply produce *normal* vehicles that are electric/hybrid powered? as simple as a motorized bicycle to a battery powered vw? where are the PRACTICAL engineers shoehorning electric systems into existing platforms? do we really needs vehicles that look like insects, have no trunk space or rearward visibility?

They had very good reasons to go with this weird shape. Your freeway cost per mile ~ cross-sectional area times coefficient of drag. 2x the coefficient of drag = 2x cost per mile = 2x the amount of batteries you must put in the vehicle to achieve the same range = 2x battery weight, price, time to recharge. They are claiming 120 mile range with 10 kwh of batteries (at 55 mph). That’s HUGE. By comparison, conventionally shaped GM Volt will have 40-60 mile range with 16 kwh of batteries. Prius conversions typically achieve 4-5 miles per kwh.
How do they do that? Aerodynamics. Their weird shape has Cd that’s supposedly 5 times lower than a Hummer and 60-70% lower than a typical economy car.
Notice that there are no rear-view mirrors or wipers. Those are very bad for aerodynamics. Instead of rear-view mirrors, they have cameras and monitors.

To quote their CEO from one of their videos, “typical windshield wiper mounted on a vehicle has the same drag profile as this entire car”.[/quote]

A car is more thena drag number.

i think temporarily there will be a suckers rally
as Financials shoot up then the next strong breeze
comes and all these financials collapse.

this is a chance for the insiders to screw the rubes
one last time, and then run.

i think the boomers are moving out of the burbs into the cities
and the early boomers are not in great shape because
none of them saved enough.
