Whats so good about these engines I dont understand?
Ford managed to quickly engineer a direct-injection, twin-turbocharged engine setup that makes more power than any other engines they offer (sans the GT500's 5.4L S/C V8) and get better fuel efficency as well. Best of all, Ford will have the engine in some of their new cars within the next few months, and afterwards, will eventually start popping into everything from Ford Fusions and Tauruses, up to the big F150.
So, personally speaking, a 340 BHP twin-turbocharged V6 that that gets fuel efficiency ratings as high, if not higher than the current 3.5L V6, this pretty much makes this new setup one of the coolest things ever that Ford has done.
...And with that little 2.0L direct-injection turbocharged engine coming along with 260 BHP, my hopes for a serious-performance Focus or Fusion (this engine may replace the N/A V6 option in the Fusion/Milan/MKZ), yeah, its just an awesome move on Ford's behalf...
So, its not necessarily a HUGE jump in automotive technology, but more or less, a seemingly HUGE jump for an American automaker. As far as I can recall, Volkswagen and BMW are the only automakers that offer direct-injection/turbocharged engines in the US, and thats only the 2.0 TSI and the 3.0L N54 (?). Maybe Acura too, I think the engine in the RDX is as well... But, everyone else offers a non direct-injection engine somewhere in the lineup, but it generally isn't the "run of the mill" cars that Ford will be going it with. Making the technology cheap and efficent, not to mention powerful, is why it is so important.
...And consequently, it will be GM/Chrysler/Toyota/Honda and the like that will have to play catch up with their mainstream vehicles...
GM says they're sticking with V8s on the high end, strapping DIG (direct-injection) and cylinder deactivation on everything, and adding E85 capabilities across the board. With Chrysler, who knows. They'll probably just buy VW parts again. As for Toyota, I have no idea there either, they don't seem to be banking on much outside of Hybrid power. Honda is playing the direct-injection game too, but only in a select few of their vehicles.
So, in summary, its not a HUGE deal on the total landscape of the automotive industry, but it truly is a HUGE deal for Ford and in general, the American automotive industry.
