Who Makes The Best Engine?

[goron59]

So I was watching this video entitled "Who Makes The Best Engine? Comparing Specific Outputs"



.. and plugged some numbers in for the Macan.

The humble Macan with the VW engine does best. Better than a Veyron!
Turbo does worst.
(assuming I got the numbers right - boost figures hard to pin down, and there's prob a mix of PS/bhp going on there!)

Just a bit of fun really.

Edit: updated pic to show more cars.

Immediate reaction is that it's a shame that at least a couple of other engines aren't included there for comparison, eg the 300bhp VW (eg Golf R) engine, which would presumably push the BHP/l figure to around 150 (not sure about 'corrected for boost) and which could, at least in theory, end up in the Macan 2.0 (in both senses of 2.0).

And an F1 engine just as a reference point. (And ignoring the fact that you need a new engine every 1K miles - or something like that!)

An F1 engine is in the video. I can plug in any other models you like. I just need the boost and CR numbers.

My old R8, for example, gets 92.93 - not bad for an old V8 lump!

I think the current Golf R is something like CR=9.3 and Boost=17.4psi (1.2bar) to make 306bhp (at least before the new PPF and WLTP tweaks are introduced).

They are all cr4p.

For real engineering power per litre you need to look at Honda, Suzuki, Kawasaki and Ducatti.

Even my old Triumph 1000cc from 2006 had 125 HP.

A Honda 1000cc was producing over 150HP.

The Ducatti Desmo produced 197 HP from its 998cc.

For sheer fun per mile 2 wheels beats any 911, Cayman etc and you do not need to spend vast amounts of cash to do so, my Triumph Bonnie only produced 45 HP yet it was a joy to ride, the handling limits were much lower than my Macan Turbo but the grin factor was off the scale.

You need to watch the full video Col - he does talk about bikes but cautions the need to include a balancing factor of compression ratio and revs to get like for like performance.

(My old TKM / Hewland Arrow kart engines were under 100cc and produced up to 30 bhp at 16000 rpm, back in the mid '70s / early '80s - not sure of the relevance but there you go!)

Added Golf R and a few others and updated the table in the original post.

Bhp/litre is not a great measure in isolation. My c.1970 single seater has a Ford Cosworth BDD with an output of 131 bhp/litre. The problem is that almost none of it is produced below 6500 rpm and even then there is not much torque. My Boxster produces about 140 bhp/litre from a 2.5 litre turbo, but more to the point has loads of torque and a pretty flat torque curve from 1900-6500 - which is why it can hit 60 in 4 secs dead even on Porsche's conservative figures.

Insightful
But then you didn't watch the video, did you?

...the i10 for me then
