Largely due to its solid reputation for quality and reliability,Toyota's mid-size Camry has been the best-selling car in America for seven of the past eight years. But it has also been less than exciting,so Toyota decided the best way to keep it on top was to broaden the appeal of its all-new 2007 Camry by improving its styling,performance and dynamics. Its curvier,though still conservative design provides more real and perceived room inside,and its steering,braking and handling are improved with a ride tuned toward comfort (although in the sportier SE the tuning is biased more toward crisper handling response). Engine choices are an updated 158-horsepower 2.4-liter four-cylinder or a new 268-horsepower 3.5-liter V6.
