Alonso gets revised Honda engine for Monaco

Autosport understands Alonso will receive a fresh internal combustion engine - his third of a permitted five for the season - for this weekend's Monte Carlo F1 race, but the new unit will only feature a reliability update.

Team-mate Jenson Button will continue to use the same ICE he used in the recent Spanish Grand Prix.

Both cars will also be fitted with new batteries and control electronics units, which Autosport understands have also been updated for reliability reasons.

Honda has yet to decide when to spend the 14 remaining development tokens it still has available for the rest of 2016.

Rival manufacturers Mercedes and Ferrari introduced small performance updates earlier this season, while Renault is set to introduce a significant upgrade for two of the four cars it supplies in Monaco, after a successful test of a new specification of power unit in Spain last week.

Honda's motorsport chief Yusuke Hasegawa has already stated Honda intends to spend its development tokens on substantial updates, rather than taking small steps throughout the year.
