Re: [DMCForum] RE: [DML] 50 Worst Cars-What Moron Wrote This?

Crikey you two :-)

NB electric motors and their controllers (not to mention batteries) have 
come an awfully long way since 1996 and in the realm of Robot Combat 
alone lurks some serious talent AND experience when it comes to high 
power DC motor controllers. The hard stuff has already been done. To run 
higher voltages and more current basically involves simply racking up 
more FETs in parallel. And I use the term DC in its correct form because 
I suspect the so-called AC motor controllers you refer to are actually 
brushless DC motors.

FWIW our very own robot used prototype high energy NiMH cells made in 
France by Saft for a PSA (Peugeot/Citroen) hybrid car project which was 
also canned, though not through any conspiracies. I suspect they twigged 
fairly early on that they couldn't get the supposedly cleaner greener 
hybrid engine down to the kind of fuel economy (and certainly nowhere 
near the power) being gained by their very own diesels (which are among 
the best in the world - I drive one).

Are you saying the Tesla is being stumped by the car boys? I suspect 
they may -just- meet their match given the kind of money behind it.
