Thanks Sunny, but with all due respect I wasn't confusing those two cars. I've been following Audi's motorsport endeavours closely since the Group B days and am well aware of the difference between an R8 LMP and an R8 LMS (note that I said "past couple of seasons"; the R8 LMP hasn't competed with factory backing since 2006.) Granted though, it's an easy mistake to make for casual fans who are unaware of the origin of the R8 road car's name and therefore that of its racing derivative (which is actually known internally as the R16.)
The R8 LMS cannot be described as "sucky". This car scored twenty three wins and three champion’s titles in its debut season last year including three race wins, six podium finishes and the top two places overall in the FIA GT3 championship you mention. It was second at the Nürburgring 24h, third at the 24 Hours of Spa (both at its first attempts) and scored six podium finishes and one overall win in the ten race VLN Endurance Racing Championship at the Nürburgring.
Its 2010 FIA GT3 championship campaign has proven to be tougher (as it has indeed also for last year's team's champions Hexis AMR), yet it has proven to be at least as consistent as its rivals and still managed one win and two podium finishes with only one race seeing no R8s in the top ten. It was third at the Nürburgring 24h (after locking out the first two rows in qualifying), was showing strongly at the front in the Spa 24h until accidents and misfortune took out several of the leading cars, and again took no fewer than six podiums in the ten VLN races.
The R8 LMS has rapidly established itself since its inception and has proved to be a hugely popular race car which sold out very quickly indeed. I look forward to seeing what the likes of United Autosports can do with it in 2011 continuing its development and success. There's more to GT racing than the FIA GT3 championship you know.
