I have been toying around with the idea of getting a hybrid. How does gas mileage fare with the new Toyotas driving up/down big elevation changes. My morning commute takes me downhill about 1500 feet in the 1st 7 miles at 50mph, then level the last 10 miles at 75mph. Reverse that on the evening commute.

Anyone with a similar commute have any tips or recommendations.

Thanks,
