As a Audi fan , the R8 is by far the best of the LM cars . it tunes nicely and handles well.....their are other LM cars (all the past Le Mans winners) but for the price it's nice.....thereare 2 versions, '01 R8 with a yellow rear wing and the '05 R8 in Playstation colors......The '01 tunes to 908hp and the '05 to 916hp. I ran my '01 at the Indy 500 endurance event anddid it in 2hrs,28mins with an 11 lap lead.....better than my Peugeot 908.
I've seen it on track, racing against it but yet to see it in the UCD. I have only seen two R8 LMP's; one being the Team Oreca and the other being the silver/yellow #2 car.
