Weak ignition coils? V70-XC70

On my old Volvo 245 (LH 2.2 system) the spark plug gaps were set at 0.028 inches. I figured that Volvo used a weaker coil than I was accustomed to. Most engines that I had experience with used a gap somewhere between 0.035 and 0.050 inches, unless the engine was supercharged, then you decreased the gap so that the increased cylinder pressure did not blow the spark out. My GMC blown Big block Chryslers and Chevys often use a gap as tight as 0.025 for this reason.

Now with this 2.4 normally aspirated engine in the V70, Volvo still calls for a gap of 0.028 inches. Are our coils a tad on the weak side or what? Any thoughts on this?
