What’s your power output per liter of displacement? I’m at 143.75 per litre in the ST (230HP/1.6L) and 21.6 in the truck (call it 80HP/3.7L).

A Hellcat engine comes in at 128.5 per liter.

83.5, definitely not the most power efficient machine.

68 for me.

1990s-era engine, not forced induction. Blown engines often get excluded from these comparisons because you can crank them up to whatever you want....for a while!

Power per liter is a horrible obsolete way of measuring engine efficiency.

should go with some kind of power per physical dimension

HP/litre makes no sense unless you use effective displacement (displacement * ( pe ak boost in bars+1) ). Otherwise, smallest motor with highest boost will always win, no matter how poorly designed.

i.e. an 82 Honda CX500T made 200 HP/litre, while being pr etty damned basic.

the 328i is at 77hp per liter. Not horrible for an NA engine. my wife’s Fit is at 77hp/liter as well which is kind of funny. It has half as much power, but also half as much displacement. 3 liters for 230 in my car, and 1.5/115 for her’s.

So a car that makes 100kW for an hour by using 10 kg of gasoline would be 77.5% efficient; which is laughably high

((100,000*3600)/464,000,000)) *100

Gasoline has an energy content of 46.4mJ/KG

(I think, I’m yet to take thermodynamics, so I don’t want to claim it’s correct)

The LS430 (was) 69/L

The LS400 is 60/L

The LS430’s likely replacement will have the same HP/L but with a slightly bigger engine.

Um, the Fiat has 221 WHP for 1.4L, so a modest 10-15 % drivetrain loss would mean ~246-260 HP, so that would be 175.7 -185.7 HP/l

The short answer is: It depends. There’s really no way to measure how good an engine is full stop. Many parameters are in mind. Maybe you want to see how fast the engine can gather and loose power, and that could make it horribly inefficient in terms of fuel consumption, but it’d make for a fun car!

You’d need to have the engine on a dyno on it’s own in order to get real consumption. You’d plug (as I put in the other comment)

Power in kW

Time elapsed in seconds

Energy of fuel in MJ/KG

Consumption of fuel in KG

Engineers use Brake Specific Fuel Consumption, it’s a 3D graph and much because you could use different engine RPM ranges.

And horsepower per liter doesn’t seem like a bad metric to me as far as a way of comparing engines.

In that regard using torque per litre could be the best way to compare them as far as how *good* an engine is.

Like, diesel engines are typically more efficient in a BSFC chart, and casually diesel engines tend to have more torque per litre.

But Diesel engines make less power typically than a similarly sized gasoline combustion engine... and power is the fun stuff!

I think if we multiply (horsepower)(mpg)(vehicle weight) we would have an arbitrary number relative to power and efficiency, obviously maximum horsepower is not used to achieve the fuel economy rating.

It’s a 201 HP 2.4L 4 banger

I’d also like to point out that it makes more power than the new Chevy Blazer

Does the Speed6 run? Yes. 118k miles on the odometer. About to take it on another 3,000- mile roadtrip next month. It’s been largely problem-free since I bought it last summer.

IS-F is 83.2 per Liter crank.
Crosstour V6 is 77.4 per Liter crank.

Throwing approximate weight values in there,
IS-F is approx 3800 lbs, so ~0.02189 HP per Liter per pound
Crosstour V6 is about 4100 lbs so ~0.01889 HP per Liter per pound.

We could play with numbers all day, I’m down for that.
Both are naturally aspirated. 

Edit: we should probably mention NA or FI.
