PISTOL123: Consumer Guide Auto (dalam Bahasa Inggris)

PISTOL123 As noted, the experimental four was Weslake's choice as the basis for the production XK-series six. The transition was straightforward enough. First, two more cylinders were added and bore was brought up to 83.0mm (3.27 in.), yielding displacement to 3.2 liters (195.2 cubic inches). However, low-rpm torque was judged insufficient, so stroke was stretched to 106mm (4.17 in.), resulting in the final 3,442cc.
