Driving the V6 seemed like it had more pep, as it was eager to jump up in RPM and go. Driving the V8 is more relaxed. With the V8 I tend to accelerate onto the freeway at 2,000 RPM, exceeding the speed of everyone around me. Calmly motoring with torque. Quite a contrast to the reliance on the higher RPM horsepower of the V6.
It seems that many here are sensitive about their choice of engines. My comments are about the differences, and my preferences.
I remember driving a rental V6 4X2 4Runner for about a thousand miles before getting my V8 4X4. I drove all thru the Ozarks on the twisty blacktop roads and some of the Forest Service roads. Driving the V6 was quite a hoot and the quick revving engine was so eager to please.
In contrast, driving the V8 on the same Ozark roads is an exercise in finesse. The best way is to relate it to motorcycling, in that the difference between the two engines is similar to riding a 600cc sportbike and my BMW 1100 GS. Both are great fun, just a lot different.
