Yes, Fisker made cars before the four door Karma. The time when the company was just a small starting bespoke design firm in Orange County, CA, and was named Fisker Coachbuild. The unique Tramonto, one of the two models ever manufactured by Fisker Coachbuild, shares design cues from the BMW Z8–after all, they were both designed by the same person, Henrik Fisker. 150 units were meant to be built–but only 15 ended up in the world instead, making it quite a collector's item. Handbuilt in California in 2006, the car is a hardtop convertible, just like the Ferrari California, and shares the same base architecture and transmission of the Mercedes SL55 AMG.
All of the cars ever made were powered by a supercharged 610 bhp AMG v-8, except for one of them, model 15 of 15, which was equipped with a 700 bhp v-12. The v-8 gave amazing performance figures, with a 0-60 time of 3.6 seconds and top speed of 202 mph. That's almost Ferrari 458 territory. Of course, the v-12 was even more spectacular, as it got to 60 mph in 3.2 seconds, and had a top speed of 205+ mph. All of this is impressive, considering the fact that it's a hard-top convertible.
The wheels on the car, which were 5 spoke aluminum alloys, were designed by Henrik Fisker as well.
