I have driven hybrids. Not an LS hybrid. Sure it has 78hp more than a non hybrid, but it also weights 1000lbs more! Why do consider it more desirable?
Again...it's all in the drive. It is unlike any hybrid you've driven. Or any I've driven for that matter. Part of this goes to the V8. Part of it is the CVT. A CVT with a V8 makes lots of sense...since CVT can take advantage of the generous torque curve of a V8. This isn't really a case in a 4 cylinder. Now add in the additional 221 lb ft torque from the hybrid. The torque is INSTANT. Everywhere. There is no downshift, no loading up...just INSTANT. And not only that, because of the hybrid and CVT, it's essentially peak torque...everywhere in the RPM band....at any time. I read an article that said it's akin to having ~600 TQ anywhere in the rev band. This hybrid behaves more like an EV than a hybrid with the way the torque is delivered.
You have to drive it to understand, really.
Maybe Wing can describe it better than I can??
