Check Bentley for the HP specs.  If I recall the 2.1 is said to have
about 10% more HP which would seem reasonable for 10% more displacement.

When I first got my 2.1  (69K) it got about 20 - 21 MPG on the highway,
a little better than my previous 1.9  (100k) at 19-20 MPG.  Now about
30k later the mileage has dropped to about 19 on the highway but I'm not
sure if it's due to wear or misadjustment, malfunction, etc.  (both
non-Westys)
