For merging in traffic and maintaining highway speeds, 180hp and 320lbs of torque are more than enough power. Now the diesel won't achieve the 5.6 second to 60 mph speed of the gasoline v-6 engine, but it's 8 second to 60 mph time is above average for most SUVs on the road today. Those who buy quick accelerating performance cars very rarely use the full potential of their capabilities anyway. They will test the capabilities of the hp engine a time or two, but to continually drive at full capability will get you arrested or killed.
Now, don't get me wrong, I am red blooded and American and love hp fast cars. For that there is a Corvette in the garage; however, it is rare that it gets driven at full capability, very rare.
The diesel F-Pace will fit what my wifes needs for daily driving very well. She currently is driving a Lincoln MKX that is much heavier than the F-Pace and is rated at 6 seconds to 60 mph. She has never been in a situation, that I know of, where she needed that kind of acceleration capability. The Mkx gives her about 22 mpg with her driving style, I expect the F-Pace to yield high 30s to low 40s.
I have not driven a diesel F-Pace yet, but have driven similar diesels with the same horse power and torque. I am confident the diesel F-pace will not be an underpowered slug.
