Productive Product: The Tesla Roaster  isn't your only choice in high-end electric sports cars anymore. A new choice is the Hybrid Technologies  L1X-75  -- check out the Popular Mechanics story  and The Wall Street Journal video .
If you're an engineer, then the chances are high that you've built a 1/10th scale radio-controlled car kit, piloted a dragster from 0-70 in 3.5 seconds  at the Malibu Speedzone , or got back on line for a second spin at Disney World's EPCOT Test Track  ride. In which case, like me, you already know the thrill of electric torque.
My own ride, a turbo Miata, is already lightweight, powerful, and pull-me-over-red. But with some aftermarket performance modifications, it gobbles (premium!) gasoline like a Winnebago.
So I'm thinking that a head-to-head product review might be in order -- say, Tesla vs. L1X-75 vs. Lotus Exige . :)
All under the banner of studying their electronic components, of course!
