A few posts ago, I wrote about XM radio passing four million subscribers. In my book, I’d say that’s pretty successful — at least so far. Another hit is Toyota’s Prius. Here’s some interesting facts about the Prius as reported in the WSJ today:

• Toyota sold 11,345 Prius vehicles in April alone
• The Prius outsells the entire Mercury product line
• The Prius outsells the entire Volvo plus Jaguar car lines

Toyota plans to try and parley the success of the Prius into some of it’s other product lines such as the Camry:

The Japanese auto maker said it will invest $10 million to start production of the Camry hybrid — the first hybrid vehicle to be produced in North America by Toyota — in the second half of 2006. It plans to produce 48,000 hybrid Camrys a year. That would be slightly more than 10% of annual Camry sales in the U.S., which totaled 426,990 last year.

Detroit has a lot of issues — especially it’s high labor and pension costs —but it would surely do a lot better if it relied less on large SUVs to make all of its profits.
