Porsche versus BMW at the last

With three hours left in the ADAC Zurich 24h Rennen the battle at the front is far from done with the #25 BMW closing to 1:35.1 secs of the leading #9 Porsche. The result remains in doubt. The Farnbacher Ferrari is one lap down in third and matching the pace of the leaders. Porsche have hung on grimly to the lead with their Hybrid Racer, seeing off the Audi challenge, but BMW can never be discounted and the Ferrari could still get lucky.
Many is the time that a 24 hour race is settled long before the finish but that is not the case here. We are in for a nail-biting finish. RLT.
