View Full Version : Strange W202 engine fact...

Working though some numbers, the 280 motor produces the more horse-power per liter of any MB motor (excluding Kompressors, turbo, and some AMG engines of course).

I find this to be a strange fact.

I think the only N/A motors that beat the 2.8l motor are the C43 motor (by a fraction) and or course the high output I6, AMG designed, C36 engine.

But add only 5 HP (easy to do) to the 280 motor and it has more HP per liter than the AMG C43 engine.


This is strange if you think about engine size and performance (2.8 beats the 2.6 also). Maybe 2.8 liters is the sweet spot for this design (of course, it's irrelevant to real world performance, if the cars weight doesn't change much and you add a bigger engine = more power = more speed). Someone did say that MBs three valve motors do not scale well. Can't wait for the Direct Injection line up and MB is going back to 4 valves per cylinder with these engines.



Now in the torque department…that's a different matter.

The 2.8 liter V6 produces about 69.3 HP per liter (add 5 HP to the 2.8 and you have 71.0 HP per liter)

The C43 produces about 70.7 HP per liter.

And the I6 3.6 liter AMG motor produces a whopping 76.5 HP per liter.

Just for the record, the 2.8 and C43 motor use a compression of 10.0:1 and the C36 uses 10.5:1

Hmm, I want 10.5:1 also,.

I hate to burst your bubble, BUT Honda has you beat!!! The S2000 pulls a whopping........120 per liter. It is a 2 liter with 240 horse power. That is better then a Ferrari.

Hehe, notice I didn't include other manufacturers. If I had I would have added this info:

Altima: 68.5 HP per liter.

Now the 350Z: 82 HP per liter (not bad).

I know about the Honda, but I think there is a good reason MB engines have equal or more torque
then HP (quicker, smoother, quieter...maybe ?).

A lot of muscle cars are the same way.

I would guess that motorcycles produce even greater HP per liter as well.

well, S2000 does have 120 HP/L

but what good is it up @ 8100 RPM mark? or and don't forget the fact that there is almost no torque... for street driving I'd be glad to loose some hp for more torque, but the racetrack is different.

S2000 is at home on a track, but day to day I'm not so sure about it, but to each his own...

BTW, great 4-bangers were the 968 and 944S2 porsche (well the 944 Turbo is great, but we are talking about NA cars), 240 hp (for 968) from 3.0L 4 cylinder and plenty of troque! too bad 968s are so rare.

the best 4 banger of all time imo was the Lotus Esprit S4S 300+hp and good top end

now about AMG stuff, what's pretty depressing until they started bringing back their kompressors on AMG models is that the first and last car they did with MB and did major tuning on was the c36
after that they just did minor tuning and mostly esthetics
i mean c43, just grabbed motor from the e430 didn't even enlarge the displacement only boosted little hp; e55 they grabbed the 500 motor and added .4l etc; c43 was what 27hp increase over the 430, and e55 was 47hp increase over the 500, but on the c36 it was quite a bigger difference from the 280, approximately 86hp or so. even now with bringing back the kompressors it's not really hard to slap that on there, so i can't wait to see what they do again with N/A do they take the easy way out, very cost efficient or do they do break a little sweat and go the extra km.

oh well just an observation over the years seeing what they did in those years

oh and their major tuning best car ever imo: the Hammer (124) hands down :)

Well, I completely agree. The C43 isn't that much faster than a CLK 430.

It's almost like we have to mod our cars to give us the power MB didn't. 20-30 more HP can make enough of a difference.


I remember reading about the Hammer in old an Road and Track.

98_Benzo dont want to burst your bubble but that statement was true for the old s2000. Motor trend oct. the buyers guide issue has the 2004 s2000 @ 2.2L and 240Hp and 240/2.2= 110 HP/L. They added .2L to get a better power band because they saw how worthless it was to have an 8300 peak (now @7700) for the proformance (And for hi-rpm motors look no futher than F-1 to see how poor Honda is at it). And in that same issue look at the "Stradale" Modena Ferrari it comes in at 425Hp @ 3.6L (425/3.6 = 118 Hp/L) I belive that the Stadale is a prodution car, if not, then to compare the two is even more unfair than it all ready is. Also that is only for a naturally "asperated" motors look around and you can find some huge HP/L numbers once you add turbos and superchargers. Think if Audi actually tuned their "Bi-Turbo" motors up, yes break-downs go up but more power than you would ever need.
