I've always thought (even heard) that the E46 M3 has the most powerful 6 cylinder, naturally-aspirated motor (without any forced induction, of course) until my brother-in-law called me to tell me that he just got into a race with a brand new Porsche 911 GT3. When I did the research, it looks like the M3's motor was dethroned by the more powerful 3.6L 380 HP (105.5 HP per liter). The M3 is 104 HP per liter, just 1.5 HP less per liter. Oh well, it was good to know that we were #1 for quite some time.

Ferrari 360 Challenge Stradale
3.6L 425 hp = 118/L


of course that engine is not a 6 pot.

Are we talking about 6-pot engines only here? If not then the new Lotus Elise has something like 106 per litre

EDIT: or the Exige, I forgot which one. Maybe both
yes, 6 cylinder normally-aspirated motors (no superchargers or turbos). which Lotus Elise are you referring too? I don't know of any Lotuses that have that much power (106 hp per liter).

Exige has 190hp stock from 1.8L
S1 Elise S190 had the same engine I believe

and the new Elise S2 has 190hp 1.8L engine.

doesnt the s2000 have a 2.2 liter engine putting down 240 hp. (i believe)
120hp/L, not much torque tho.....

your math is off :)

it used to be 2.0L so it was 120hp/L

now 2.2L so 109/L
of course they dyno wayyy to high to only have 240hp.

Doesn't the Toyota powered US spec have sth like 189hp? As well as the 111R and Exige
Thats correct. The 111R elise as well as the S2 exige both have the 190hp Toyota 2ZZ-GE engine. Hopefully they will bring the exige to the US with a supercharger :drool: that their have been rumors about that will provide for alittle more power and a much higher price tag, and then you will have yourself a very nice high hp to L ratio. -Michael. :thumbup:
