Actually it seems to have such sensors. According to this links all you need is a speed sensor and an injector.
Links for devices (in russian, sorry... )are here:
1st device - for now i've found only wiring diagram with pics
2-nd device looks like this
According to the manuals they can provide you following data:
actual MPG (in L/100km format)
trip mileage (in km)
actual speed (km/h)
0-60 mph time
If interested i'll try to find out more data
