Maybach HL 230

To increase the performance of the Maybach HL 210 P30, its cylinders were bored out, increasing the displacement from 21 000 cc to 23 000 cc. During production, the Maybach HL 230 maximum rpm was reduced to 2500 by the factory, reducing engine wear.

Two versions of the Maybach HL 230 existed, the P30 and P45. The P45 was used on the Tiger I and variant, while the P30 was used on the Panther and Tiger II, and their variants.
