MILAN, May 20 (Reuters) - French automaker Renault

is willing to supply technology to other carmakers to

help increase the total output of vehicles with shared features

that make them cheaper to manufacture, CEO Luca De Meo said on

Tuesday.

De Meo, an Italian national, told a parliamentary hearing in

Rome that Renault was not discouraged by its recent failed

attempt to cooperate with Germany's Volkswagen.

"We remain fully open," he said.

Renault, which over the years has cooperated in specific

areas of the market with several of its rivals, including

Mercedes and Fiat, last year started discussions with

Volkswagen over a plan to jointly develop an affordable electric

version (EV) of the Renault Twingo small car. Europe's largest

automaker walked away from talks after a few months.

De Meo said on Tuesday that sharing technologies - including

platforms, the architectures that can underpin several different

models - could prove particularly useful in the areas of small

cars and commercial vehicles.

"These normally require huge investments for small margins,"

he said.

Last week, in a joint appearance with Stellantis ( STLA )

Chairman John Elkann, De Meo said Renault was not making money

on some small cars, adding that between 2015 and 2030

regulations will increase the cost of a medium-sized

Renault-built car by 20% and for small cars by 40%.
