What car has the most hp per liter?

I bet everyone will get it wrong.

Update:

It’s the Tesla Model S P90D, with 762 hp and 0 liters.

Infinite hp per liter

is it still the C/GLA45?

I assume turbos count? Because among NA engines, I thought the production car title was still held by the S2000 engine from the early 2000s. 110hp/L, something like that.

IMHO, forced induction make the stat a lot less meaningful. But still interested in hearing the final answer...

8 or so liters making 8-10,000hp = 1000-1250hp/l

Horse shit the Ferrari Berlinetta Boxer had a 1.1L flat-12 to meet Italy’s stringent displacement tax laws and generated around 1,345bhp.

I remember reading about a 0.9CC engine (or was a 1Liter) tuned by NISMO that produced around 300BHP

Technically the Tesla is tied with the Leaf and i3.

Nope, because the tesla has more hp. So the Tesla’s infinite hp per liter is more than than any other electric car’s.

Too vague of a question.

Are we talking all-time production?

Mitsubishi Lancer Evolution X FQ-440 MR

440 HP out of 1998cc.

Are we talking current cars?

McLaren P1

727-hp from 3.8L is around 191/L

If we go to race cars it’s tough to call because they don’t always publish accurate power numbers. Especially in the Rally cars.

It’s all time production, and it’s the Model S P90D

When you divide by zero, the result is infinity. There is no numerical difference between any of these infinities, all of them are equal.

I heard the tesla motor is about the size of a watermelon, so that displaces about 4-5 liters of water. Ergo, tesla is not the best.

Jdrentarol > Aaron M - MasoFiST 01/28/2016 at 09:26

But still, the Tesla Model S P90D has 762 HP and 0 liters, and the Nissan Leaf has less. So... model S wins?

Liters refer to how many liters of air can be crammed into each cylinder at a time. Not water.

I’m not playing a semantics game, but the motor in a Tesla is the size of a watermelon and though there are no cylinders, those coils add up to something. There is a “Displacement litre equivalent” just like the MPGe numbers.

Aaron M - MasoFiST > Jdrentarol 01/28/2016 at 09:31

That means the Model S has more hp. It does not mean it makes more hp/liter. If you’re going to go through a mathematical loophole, you should at least be consistent.

:-p

So then it’s a wrong comparison as the tesla doesn’t use the same method to make power.

Also, something divided by zero doesn’t mean infinite, it means an incomprehensible outcome. This is not a function in calculus like “as X approaches zero” which is what gives you infinity as an answer since it cannot approach zero. You start with “displacement is at zero”. Which isn’t allowed.

SCIENCED! AND MATHED!

One infinity can actually be larger than another.

I just had a divide by zero error. You can’t divide by zero, dude.

Dividing by zero is not infinity.

Yeah, you’re not right because talking about hp per liter is implying there is an engine.

I get it’s a riddle and that’s the catch, but let’s be serious, that isn’t a non-displacement engine. It’s just an alternate-displacement motor. Just like how it can’t have MPG, since it doesn’t run on a storage of G.

This question also reminds me:

100/L used to be something to be proud of. Now my compact beats that by a good margin. It isn’t even a particularly unusual or special car.

Actually you’re still wrong. You cannot divide by zero. Infinity is the result of the limit as x approaches zero for 1/x, as x cannot ever BE zero. It will always be non-zero but get infintessimally smaller while the result of 1/x gros and grows and grows.

Division by zero is, at its core, impossible.

Liters per hp

If no liters, no comparision

Undefined =/= infinite

Electric cars do not make ANY hp/l because there are no liters.

Depends on your definition and how you choose to define your asymptotic result; technically it is a limit rather than an arithmetic result but for the OP’s case that’s pedantry. Nonetheless, the limits are functionally equal, which is the more important conclusion.

EDIT: You can divide by zero in complex analysis, “you cannot divide by zero” is not a factual statement so much as a high school math teacher’s way of not trying to explain complex analysis to their students.

Aaron M - MasoFiST > BorkBorkBjork 01/28/2016 at 09:56

All of these infinities are unbounded limits; you’d need defined infinite sets to compare their sizes. So while not all infinities are the same size, these infinities effectively are.

Yes but these arent Riemann spheres or anything like that. This is the calculation of specific output. So for that equation, you can’t divide by zero. This is the equivalent of those facebook chain questions which depend on people being terrible at order of operations or communicating poorly in general and the end result is meaningless anyways.

The result is absolutely meaningless, of course. But dealing with absolutes is what got us here in the first place, and I’m on a conference call and have nothing better to do.

Actually your answer is wrong because you divided by zero.
