EA is billing the Wii U version of the game as the 'Enhanced Version', including entirely new co-op features. There's a local co-op feature called Co-Driver, which lets one player drive by using a Wiimote or the Wii U Pro Controller while another person uses the Wii U GamePad to provide navigation assistance on an interactive map.
EA provided the following example: "Using just their fingertips, a partner can distract pursuing cops, switch from night to day or activate enhanced performance for any car and even control the amount of traffic on the road.
"This is the ultimate advantage for gamers who like to stir up trouble for the cops, their friends or just for fun."
The touchscreen can also be used in more subtle ways, like switching the mods on your vehicle or change your car entirely. You can also play the game on the GamePad's screen.
And in keeping with its 'Enhanced Version' title, the Wii U version will ship with the Ultimate Speed Pack, which contains the McLaren's F1 LM, Bugatti's Veyron Grand Sport Vitesse, the Pagani Zonda R, the Aventador J and the Venom GT Spyder.
