Order custom post type is beign ignored

quick info, use this to know what is being return:

$loop = new WP_Query( array(
    'post_type' => 'car',
    'orderby' => 'title',
    'order' => 'asc'
)
);
echo '<pre>';
print_r($loop);

wp_reset_postdata();

Also I believe is better at the end reset the postdata to be sure that nothing is being change in the database. For all I had read this is good to use everytime we open a new WP_Query.
