I don't believe the 4 cylinder has a timing belt, but it does have a timing chain, which should be good for the life of the engine.

Toyota's website lists the mileage for the Highlander Hybrid at 20 mpg city/ 27 mpg highway for the V6 hybrid engine. The Highlander is also offered in regular V6 engine and 4 cylinder models.

The milage of SUVs varies by the make and model. Proper maintenance also helps an SUV gain better milage. Comparing different SUVs by year or by make is the best way to choose one with the best milage. The Hyundai Tucson gets 22 City and 27 Highway. It's a little more efficient than the Toyota Highlander, but also smaller.

Toyota has the best milage for me and I feel that if you test drove all makes and models that they would be the one that you would chose for its simplicity and form.
You don't.
Milage... The counter tracts milage ...about 8,000 kms from 100 % to 0 %
That's actually very good milage on that year. I have 94 mercury and it has 196 thousand so that's great milage.
Bad idea, replace both spark plugs and wires, using Toyota parts, will increase fuel milage and reliabilty..
The Toyota Pruis has the best gas milage out of all the hybrid cars. The Honda Civis Hybrid, Ford Fusion Hybrid and Nissan Altima also have very good gas milage.
