German - Japanese vehicles

Hi,

Perhaps someone can shed some light on this.

I wonder why Japanese brand vehicles bias their engines for peak torque output at higher RPMs? Whereas German auto makers bias for peak torque at lower RPMs where most the driving is usually done.

Case in point;
2016 Acura TLX I4 ------------------- 182 ft-lbs. @ 4500 rpm
2016 Acura TLX v6 AWD ------------ 267 ft-lbs. @ 4500 rpm
2016 Audi A4 ------------------------- 258 ft-lbs. @ 1500 rpm

In this case, the Audi will feel way more 'zipper' than the Acuras. I see this is a general pattern across most Japanese cars.

Does anyone know why this is ?
Please thank me if you find this helpful

Your comparison better be Turbo vs N/A engine characteristics rather than German vs. Japanese.
