An interesting stat? 3.0Si vs M vs E46 M3

[ph001]

It occurred to me the other day that the main ‘seat of the pants’ metric which makes a car feel more accelerative is the torque/weight ratio.

So I pulled the stats on the E85 3.0Si, M and E46 M3. Was quite surprised at the result:

3.0Si - 0.181 lbft/kg
Z4M - 0.186 lbft/kg
E46 M3 - 0.167 lbft/kg

Of course, gearing makes a huge difference but was surprised to see the M3 lagging behind the Z4 by some margin, and also how similar the 3.0 is to the M.

Never seen those stats before but it doesn't surprise me at all.
I've always said for the average forum driver (of which I am one) the auto 3.0 Si would reach 60mph before a ZM driven by a average forum member.
Plenty of punch in the N52

Lot more to it than that though, our devil-fuel X3 has over 0.220 lbft/kg and max torque from 1500rpm but still only manages 0-62 in 5.7sec (although it may be a bit faster now it's done 20k and the engine has loosened up)

PS surely you should be referencing Nm/kg, Nm/T or lbft/lb rather than mixing Imperial & SI units

Ah but the noise from the S54 from 6900 to 7900 rpm is worth the price of entry on it's own.

Can somebody smarter than me convert these stats to American English :?

Just divide the lbft of torque into pounds instead of kg? :?

Interesting post.

0.228 lbsft/kg for the 718 GTS.

Not that Stuttgart shite is welcome mind.....
