Toyota Highlander Hybrid: 155.18 mmBTU
HEV has a 48.047 mmBTU production energy penalty ... ~45% more
Operation Energy 160,000 Miles:
Toyota Highlander: 6,400, 726.4 mmBTU
Toyota Highlander Hybrid: 5,424, 615.593 mmBTU
The HEV uses 110.807 mmBTU less energy over 160,000 miles.
ie ... the HEV uses less net energy once it passes ~70,000 miles.

The non-HEV produces ~80% more EPA tail pipe pollution during operation based on the difference in their ULEV vs SULEV ratings ... which will mean the HEV will be gaining ground on the non-HEV for total net pollution very quickly.
If the production energy is even remotely similar to the production pollution ( may not be the case ) ... but if it is ... the non-HEV net pollution will pass the HEV and become net larger (dirtier) in about ~40,000 miles.
