This just looks like too much damn fun! Six cars on the same track and you can retro fit the cars you currently have.
The Sport Digital set comes with a digital lap counter that can be programmed to run in 7 different race modes. One nice thing that Scalextric did was to ensure some backwards compatibility; most of the modern sets and cars can be retrofitted to become Sport Digital sets, complete with the ability to change lanes and run more than 2 cars on the same track.
