Merc 'constantly learning new things'

Cooling will be key with the new Mercedes engine as non-executive director Niki Lauda has revealed it is sensitive to temperature.

This season Formula One will swap from the old 2.4-litre V8s to 1.6-litre turbocharged V6 engines.

But while the units have been put through their paces in the factories, the teams will have just 12 days of on-track running to work out any issues.

And one of those will be cooling with Lauda revealing that the Merc engine has a "precise" operating window.

"We are constantly learning new things," he told Auto Motor und Sport.

"Suddenly you have to take care of things like water pressure or intercooling. Oil and water must be in a precise temperature window.

"If this goes beyond just a few degrees above a certain limit it tears everything up."
