At a glitzy rally in Ankara marked by flashing lights and thumping Turkish pop music, Davutoglu unveiled the party's election manifesto called "A Contract for a New Turkey".
The centrepiece of the campaign of the ruling Islamic-rooted Justice and Development Party (AKP), which has ruled Turkey since 2002, is a promise to change the constitution to create a system in which the president wields strong executive powers.
This would suit President Recep Tayyip Erdogan, who served as Turkey's premier from 2003-2014 and wants to be its undisputed number one.
"Conflicts between power centres led to crises in Turkey and a presidential system would allow discord to be prevented," he added.

Turkey's presidency under its 1980 constitution -- which was drawn up after the military coup of that year -- gives the presidency a largely ceremonial role and strictly forbids the president from becoming involved in party politics.
The new constitution would enshrine the president as Turkey's number one executive ruler.
Critics claim that Erdogan has been acting like this since he became president in 2014, riding roughshod over the current Constitution.
In a sometimes fiery speech in which he took aim at the AKP's enemies at home and abroad, Davutoglu said that the party wanted to win 55 percent in the polls.
It remains unclear whether the AKP will achieve its ambition, in what is set to be a tightly-contested election campaign.
The main opposition Republican People's Party (CHP) has vowed to thwart its ambition while the pro-Kurdish People's Democratic Party (HDP) could also upset the ruling party if it breaks through the 10 percent threshold needed to win a direct quota of seats.
