The question

To ask the Secretary of State for Defence, what upgrades will be made to increase the a) power and b) torque of the Perkins CV12-6A V12 diesel engine as part of the Challenger 3 programme.

Answered by Luke Pollard

As a precursor to the conversion of Challenger 2 to Challenger 3, the Heavy Armour Automotive Improvement Programme introduced a series of upgrades to the automotive system, including bringing the Perkins CV12‑6A engine to a common build standard. Options remain available should additional power be required in the future.
