Highest Horsepower Per Litre Production Cars

[kujiwara]

That XC90 thread got me thinking 320hp for a 2.0l is 160hp/litre which is quite high by today's standards, but probably a lot of cars will be like that in a few years. Let's have a game of name the highest hp/litre car/engine off the top of your head, try not to google and let's see what we can come up with. Factory tunes are allowed, but no hybrid or electric vehicles, we're only comparing dinosaur powered ones!

And see if you can come up with NA and forced induction cars with and without tunes.

What I can think of for new cars is the new Volvo engine with the 2.0 direct injection twin charger with polestar tune available on XC90/V90/S90/V90XC 340hp, 170hp/litre. Without tune it'll be the Alfa Romeo Guilia Quadablahblahlio 505hp DI 2.9 twin turbo, 174hp/litre

For NA cars it would be the new 911 GT3 with the 3.8 making 475 hp at 125hp/litre, the good old F20C in the JDM S2000 makes 250hp with 2.0l which equals to 125hp/litre too.

What's your pick?

I remember the Saturn Sky Red Line being close to 300hp with a 2l turbo and some option from factory.

NA, I was thinking about the S2000 as well.....

Re: Highest Horsepower Per Litre Production Cars

Highest specific output from a naturally aspirated gas engine is the Ariel Atom 500. 500hp/3L = 166.7hp/L

Bart already has the highest FI engine, and the Koenigsegg One:1 is highest for biofuel engines. 1,341hp/5L = 268.2hp/L

Re: Highest Horsepower Per Litre Production Cars

I had a similarish conversation about ten years ago when I was in London.
Not north American, off the top of my head the SEAT Cupra came to mind as a everyday car. Me and a colleague were discussing the BHP limits of a FWD Production car. The Cupra came to mind as it was hitting that limit (250/260bhp) and some going over it. What made it an exception was that it was something that was affordable, everyday, but stupidly quick for the engine size.

Wiki:
2L Limited Edition: 2009-2009
28 kW (310 PS; 306 bhp)
@ 6,000 rpm 425 N·m (313 lbf·ft)
@ 3,000–5,000 rpm

As for North America. I have not got a clue.

Don't remember the specs as it's been a long time but used to be a subaru fan and the old Subaru Impeza P1 had 160/180hpL? I might be mis remembering.

Edit: dangit, googled, only 140/L still decent for a 16 year old car? Still one of my favourites.

Porsche 959 S, 515hp from 2.85L is 180.70 HP/L, not bad for 1988.

Re: Highest Horsepower Per Litre Production Cars

Don't care what anyone says but my fave engine growing up would be the Honda b-series, the crown jewel being the B18C5 found in the ITR. The b16a was also wicked in its time. I believe it was the first production engine to produce more than 100hp per litre.

Damn I wish I got into the Honda game at some time...

Re: Highest Horsepower Per Litre Production Cars

I had a b16a in my crx and it really was a great engine. 1.6l 160hp 111tq I think.

Re: Highest Horsepower Per Litre Production Cars

I had a b18c in an integra I had for a while, burned more oil than gas I think. But that's what you get when you pay 24 Budweisers for a car.

Oh god a friends brother had one of these back in the day. He had one of the limited production line. They were really quick.
