Still not expected until sometime before summer 2009, the new Mercedes CLK is already in testing. It was caught in Gernamy and in Sweden. According to WorldCarFans, it should have three different engine choices: a V6 with 272hp, a V8 with 388hp and an AMG version with 503hp. There may also be more engines including diesel versions for some markets (mostly Europe).
