[![BLU Products unveils Tegra 3running Quattro 45, 45 HD and 57 HD](http://www.blogcdn.com/www.engadget.com/media/2013/02/blu-quattro-57-hd-1359762183.jpg) ](http://www.engadget.com/2013/02/03/blu-products-unveils-tegra-3-running-quattro-smartphones/)
It was just weeks ago that BLU Products' smartphones were largely dual-core models like the [Vivo 4.65 HD](http://www.engadget.com/2012/12/27/blu-products-unlocked-vivo-4-65-hd/). The company clearly wants to ramp things up, as it's kicking off the Quattro line based around Android 4.0 and the quad-core, 1.5GHz [Tegra 3](http://www.engadget.com/tag/Tegra3/). At the entry level is the $250 Quattro 4.5, which includes a qHD display at its namesake size as well as a 5-megapixel camera, 4GB of built-in storage and a microSD slot. The next step is, unusually, the biggest: the $300 Quattro 5.7 HD (what you see above) keeps the same storage, but jumps to the extra-large category while upgrading to a 720p display and an 8-megapixel camera. BLU sees the $350 Quattro 4.5 HD as the real darling. It beats its non-HD cousin with a curved, 720p screen touting [Gorilla Glass](http://www.engadget.com/tag/GorillaGlass/), and throws in a larger 16GB capacity as well as a more light-sensitive 8-megapixel camera. The two smaller models ship to the US early this month, to be followed by the 5.7-inch behemoth in late March. When they arrive, every one of them will carry unlocked HSPA+ 3G that supports both AT&T and T-Mobile.
