If you had driven an Accord you would have seen a marked difference in mileage. EPA for the CR-V 2WD is 27 highway, Accord gets 31 with a slightly more powerful motor.

the power to weight is also a major factor.
the CR-V clocks in at about 120BHP/ton whereas the Jaguar is at about 160BHP/ton.
That points to the Jaguar having to work less to maintain a similar speed to the Honda.
Then there's also that the VTEC systems are not about efficiency of fuel consumption but of efficiency of use of engine volume.
Honda = 90 BHP/Litre
Jaguar = 71 BHP/Litre
Unfortunately, the nature of the high output per liter engines is that torque suffers and as a result, the engines need to work harder to achieve the pace of a bigger "torqueier" engine.
