Significance of 258 ft*lbs torque, especially in turbo engines...
Posted by AlexA (more from AlexA) on Sat, 1 Dec 2018 05:32:08
The 9-5 Aero and 9-3 Viggen both generated 258 ft*lbs of torque. (OK, Viggen was 252 at first, then later years were 258).
I've noticed lately that it seems as if almost every manufacturer's turbo engines, in at least one form, make 258 ft*lbs of torque, regardless of displacement, design, boost pressure, transmission, etc etc. Is this some sort of magic number, or coincidence? And if it is a magic number, it seems SAAB was first again. (Don't get me started on the proliferation of 2.0 turbo motors right as the company that's been making a 2.0 turbo since 1978 goes out of business).
Some of the engines with 258 ft* lbs are (just from reading reviews, I'm sure there are more!):
Volvo "T5" (4 cylinder)
Mazda 2.3 Turbo (CX7)
Buick Regal/Chevy Malibu 2.0 Turbo
Lexus' new 2.0L I4 turbo
Nissan Altima 3.5 V6 (may make this same figure in other models?)
What do you think??
