Exactly, well said. Similarly, many enthusiasts mistakenly believe the Honda Insight was the first hybrid on the market, when in fact the Toyota Prius debuted years before the Insight. The Insight was simply the first hybrid in North America, with the Prius being available in North America a few months later.
Yes, the Insight preceded the Prius, here in the U.S., by about 8 months or so. The Insight debuted in January 2000 (I got to test-drive one of the first ones into the D.C. area)...the Prius not till August or September (don't remember exactly).
I don't want too take this thread too far off-topic, but, on the subject of the 1Gen Prius/Insight, I also think something else needs to be said. Introduction-time, here, though, doesn't tell the whole story.
The real difference was in the two cars themselves. The 1Gen Insight was essentially a tiny, glorified Kiddy-Car, with two seats, awkward-looking protruding rear-wheel skirts, a Bounce-O-Matic ride from the light weight and lack of suspension-travel, drum-like road noise from the almost complete lack of insulation, a simple, series-type hybrid drive-in that wouldn't get out of its own way, only available in three or four exterior colors, and, despite the hatch-type cargo area, almost no space for carrying things because of the battery-pack. Its rated payload (passengers AND baggage) was only 350 lbs, so, big guy that I am, I couldn't even drive with someone else sitting in the car without technically overloading it. This car, IMO, except for use by one or two small adults as a gas-saving regular commuter where comfort was not an issue, was essentially a waste of money....and the low sales confirmed that.
In contrast, the 1Gen Prius, despite an awkward dash and shifter-controls, was a far more flexible and usable small sedan, and had a more sophisticated parallel-type hybrid system that could run on either gas or electric alone for a limited range. It was no Chevy Suburban, but could clearly carry a lot more than an Insight, and, again, while no luxury car, was also noticeably more comfortable and tolerable in its road manners.
