There are several Wii U racing games for your boys to enjoy.Sonic All Star Racing, Need for Speed : Most Wanted and Hot Wheels World's Best Driver.
The latest Wii U racing game is Hot Wheels World's Best Driver - Wii U Standard Edition, 24 customizable
vehicles including classic Hot Wheels designs such as the Ripper, the Twin Mill and the Boneshaker. You get to go behind the curtain and unlock the secrets of the Hot Wheels
Test Facility, an ever-changing hub world where players can practice
their skills before showtime on the circuit
Sonic and All-Stars Racing Transformed Bonus Edition - Nintendo Wii U is probably the best multi user game out for the Wii U at the
moment. Up to five people can race at one time. This
is not Mario Kart but it is a pretty darn good racing game. It is
definitely worth the price.
The stages are incredible and some of them change to accommodate the
"Transformed" idea of the game...some of the courses change by lap!
Great music and smooth graphics . There is a good selection of lovable characters to choose from.
One of my favorite features--the multiplayer mode
using the game pad. Separate screens is amazing since you never get
distracted by a split screen, nor does the game pad lose a ton of the
graphic value. Plus, the game pad enables you to play with 5 players,
opposed to the traditional 4.
Then we have Need for Speed Most Wanted U - Nintendo Wii U you'll need to outrun the cops, out drive your friends, and outsmart your rivals. With a relentless
police force gunning to take you down, you'll need to make split second
decisions. Use the open world to your advantage to find hiding spots,
hit jumps and earn new vehicles to keep you one step ahead.
