2015 Toyota Camry: New York Auto Show Live Photos

Toyota's Camry is a classic case of where improving something just a little can make a disporportionately large difference.

As America's best-selling passenger car, one with an available hybrid model, any improvements are big news.

Launched at the 2014 New York Auto Show, Toyota says it has rebuilt the Camry from the ground up, though technically it's an updated version of the current car, rather than an all-new model.

Despite that, visual changes and as many as 2,000 new parts have gone into improving the car, and only the roof panel remains unchanged as far as styling goes.

It's still a Camry, of course. While changes have freshened the Camry's styling and brought it more in line with other recent Toyota product, you won't be buying it to decorate your driveway.

You do get new color choices though, and integrated LED daytime running lights. LED high and low beams are optional on some models, too.

Toyota promises a more "premium" feel from the Camry's interior, with better materials, improved amenities and a little more space for passengers.
