A thermoplastic molding composition that features improved low- temperature properties and is thus suitable for application in exterior automotive parts is disclosed. The composition contains (A) 80 to 60 percent of a copolycarbonate wherein 65 to 75 mole percent of its structural units are derived from compounds of formula (I) Image wherein R1, R2, R3 and R4 independently of one another represents H, C1-C4-alkyl, phenyl, substituted phenyl or halogen, and wherein 25 to 35 mole percent of its structural units are derived from compounds of formula (II) Image where R5, R6, R7 and R8 independently one of the others denote H, CH3, Cl or Br and X is C1-C5-alkylene, C2-C5-alkylidene, C5-C6- cycloalkylene, C5-C10-cycloalkylidene and (B) 20 to 40 percent of a homopolycarbonate of bisphenol A having a melt flow rate, determined in accordance with ASTM D-1238 under 1.2 kg loading at 300°C of 3 to 12 gm/10 minutes.
