ehsnils Posted March 5, 2008 Posted March 5, 2008 The Subaru H12 engine (as pictured in this forum elsewhere) was actually considered at an early stage to be used as a power plant in the Koenigsegg sports car. (http://www.koenigsegg.com/) Why it wasn't used was because it wasn't really suitable for a supersport car, even if a version of it actually was used in a prototype modified to 3.8 liter. Trivia: The manager of Koenigsegg is actually driving a Subaru.
Alicafster Posted March 7, 2008 Posted March 7, 2008 No he drives a Legacy. http://www.nyteknik.se/efter_jobbet/smatt_gott/article53021.ece Its in swedish but I give you a simple translation: Christian von Koenigsegg, the man behind one of the fastest cars i the world. bla bla bla... he is originally from Stockholm and lives in Magnarp, outside Ängelholm with his wife and two kids. bla bla bla... he drives a Subaru Legacy in his daily life, but drives the car in his dreams in the factory.
IwannaSportSedan Posted March 7, 2008 Posted March 7, 2008 Cool. A guy who builds the CCX, drives a similar car to me as an every-day. Why can't Subaru get him to endorse the Legacy? It doesn't present any sort of competition for his automotive product... but does establish his credibility on the subject. When they went from the Ford SVT DOHC motor, to a motor of their own casting, I wonder why they didn't go back to a flat eight, or a flat twelve. If anybody could build an awesome 5-liter flat eight, based on the EJ25x design, Koenigsegg could. The CCx series is probably already engineered for a V8, though, and it is probably easier for them to adapt a new design from the Ford modular engine, than to re-engineer for a flat engine. The CCX is also hella-cool for using not one, but two rotrex superchargers. I wonder if they use Rotrex's new two-speed gearbox-driven superchargers, where the supercharger actually can spin up at an even higher rate, relative to the engine belt speed, so it is more efficient at higher rpms, not just at lower RPMs, more like a turbocharger. Imagine that on a 5-liter subaru-like flat eight.
f1anatic Posted March 8, 2008 Posted March 8, 2008 OK Ritalin crowd... let me bring you back to sanity. Subaru H12 was a Formula One engine. Its displacement was 3.5 L and it was underpowered compared to the V10 and V12 units of the day (Renault, Honda). Read here http://www.iwoc.co.uk/subf1.html
ehsnils Posted March 9, 2008 Author Posted March 9, 2008 Subaru H12 was a Formula One engine. Its displacement was 3.5 L and it was underpowered compared to the V10 and V12 units of the day (Renault, Honda). And still it was too racy for the Koenigsegg. It actually tells us more about the F1 engines than it tells us about the supersport cars (at least of that age). Today the characteristics of a F1 engine is a bit better due to all the electronics available that allows them to be more flexible, but I doubt that they will work in a supersport car anyway. The reason? In F1 you are using a lot of top-end power but you are sacrificing the low rpm torque. In a supersport car you want the range to be a lot more flexible. It shall be possible to drive them in city traffic too (not that you really want, but anyway).
