Buick gets the Vue

Not a big surprise, really.
Buick will get its version of the Saturn Vue next year, with a new front and new interior.
The base engine will be, just like in the Vue, the 2.4 Liter 4 cylinder. I just hope they use the 6 speed auto instead of the old 4 speed in the Vue.
Optional will be the new 3.0 Liter V6.
And a year later, there will be an all new 2 mode plug in hybrid available. Although the 2 mode system as the potential of achieving great fuel economy, it will only be able to run on electricity alone for about 10 miles.
That version will use the larger 3.6 Liter engine.
And I don’t get why. A hybrid is about MPG, not power. Why not use the 2.4 Liter in the Hybrid?
