For some of you scientists or physicists in the crowd, does anyone care to address this issue? Has anyone looked at data regarding vibration frequencies at various RPMs? All I know is the seat of the pants feel of the spyder is super sweet and silky, and lots of naturally aspirated Motors are, whereas this new crop of 718 Turbo Motors doesn't feel good. On the other hand, don't laugh, but I drove a 2 L turbo Camaro convertible a few weeks ago, and the motor felt really nice. not saying the cars are in the same league, but the bucket of bolts / bag of shrapnel feel just wasn't there. The motor was silky smooth.
The boxer configuration is the only configuration in common use that does not have unbalanced forces with a four-stroke cycle regardless of the number of cylinders, as long as both banks have the same number of cylinders. These engines do not require a balance shaft
[4] or counterweights on the crankshaft to balance the weight of the reciprocating parts, which are required in most other engine configurations. However, in the case of boxer engines with fewer than six cylinders, unbalanced moments (a reciprocating torque also known as a "rocking couple") are unavoidable due to the "opposite" cylinders being slightly out of line with each other.[3] Other engine configurations with natural dynamic balance include the straight-six, the straight-eight, the V12, and the V16.
