Would early turbine engines transform British tanks?

The Princess counterfactual reaches armoured vehicles, where compact power would come with a much larger fuel requirement.

Question

How would reliable turbine engines available in the 1930s affect armoured-vehicle development?

Short answer

They would offer much greater power density, but heavy fuel consumption could sharply limit the practical benefit.

Notes

Reliable turbine engines in the 1930s would give tank designers another way to obtain high power from a compact installation. The comparison is with arrangements that combined several existing engines to reach the required output. Greater power brings a serious fuel penalty, and the exchange challenges the idea that this can be dismissed because contemporary tanks already had limited range. The Abrams supplies a later comparison for the operational benefits and substantial fuel bill of turbine propulsion.
