Four cylinder engines don’t usually come in V format, they are inline. There have been very few exceptions to this rule, with Yamaha motorcycles currently being one of the few. And Ford’s ecoboost 3 also isn’t V style, it’s inline.

Meh. Non-news. Cars get updated all the time. Not exactly thrilled with the idea of a 4-popper in a full-size offering, but with technology like direct-injection and variable-valve-geometry, it MIGHT be commensurate with the low-end Impala's of old. Mazda seems to be pulling it off with Sky-Activ. There should be a V8 somewhere in the lineup though. Or at least a big (3.5L+) supercharged V6.

Whatever. Stop-start technology is just BARELY worthy of hybridcars.com these days anyway. Real news would be seeing the Voltec powertrain developed for more cars than just the Volt (and maybe the upcoming ELR). News would be different classes of Voltec powertrains that varied in performance that could be used in a range of applications (low HP applications for small cars, higher HP applications for better speed/torque performance). Stop-start is old news, comparatively.

The E-assist is a well designed start/stop system that boosts mileage. But to equate it with the HSD of Ford and Toyota is over the top. Soon the 2013 Fusion (Sept) will hit the market and offer about 37 Hwy mileage with Ford's start/stop and their hybrid will get perhaps 44 MPG highway, and even more (47) city.

And if the Fusion is too small, consider the ES300 h, which would be bigger than the impala, and gets almost 40 MPG with a 200 hp HSD.

Point is start stop is certainly a nifty step forward, but even bigger steps are needed in the future, i.e. plug-in hybrids with a 20 mile EV range.

Good that the GM is able to apply e-assist in the 4th model, perhaps this to GM as what is HSD (Hybrid Synergy Drive) is to Toyota.

Excellent. Large car with a V4 engine.

Gone were the days when Impala SS had V8 engine.
Hope they sell well.

On another front, Ford is going to introduce Focus with V3 engine in USA next year. Already 3 models in Europe are slated to go with this engine.
