Mercedes said there was no significant damage.
Nov.28 (GMM) A fire this week was not the first incident at Brixworth, as Mercedes develops its turbo V6 engine for 2014.
Germany's Auto Motor und Sport reports that the fire brigade was called to the German manufacturer's Northamptonshire headquarters on Monday evening after an F1 engine caught fire on a test bench.
Mercedes said there was no significant damage, and that the fire department was only summoned as a precaution.
But Auto Motor und Sport correspondent Michael Schmidt said that the development of the Mercedes turbo has been troublesome, with other incidents having also occurred recently.
