The standard engine in the CE, LE, XLE, and SE is a 2.4-liter four-cylinder making 158 horsepower (155 horses for PZEV-rated motors). It’s connected to a five-speed manual or five-speed automatic transmission, and gets 24 mpg regardless of transmission choice. The manual transmission gets 34 mpg on the highway, while the automatic musters 33 mpg.

If you want more power than the four-cylinder engine can provide, choose a 2007 Toyota Camry equipped with the available 3.5-liter V6. It generates 268 horsepower, runs on regular unleaded fuel like the four-cylinder, and carries a ULEV rating. The V6 is connected to a six-speed automatic transmission, and is expected to deliver 22 mpg in the city and 31 mpg on the highway.

The 2007 Toyota Camry Hybrid combines a four-cylinder engine with an electric assist motor to create a combined 192 horsepower – about the same motive force as found in the outgoing V6 versions. Fuel economy ratings are 43 mpg in the city and 37 mpg on the highway, and Toyota says the Hybrid model will go 600 miles on a single tank of fuel.
