While other areas of its 2007 car may have been far from ideal in the battle to retain both Formula One world titles, Renault had little to complain about on the engine front.

Unsurprisingly, therefore, the regie has decided to continue its partnership with Mecachrome International Inc, awarding the Franco-Canadian company a contract renewal for the manufacture and assembly of its engines for the next three years.

"Mecachrome International has renewed its contract with Renault Sport, on an exclusive basis, for the manufacture and assembly of Formula One engines developed by Renault Sport," the engine builder confirmed in a brief statement, "The contract is for three years, beginning with the 2008 F1 season until the end of the 2010 season.

"Renault Sport and Mecachrome have been collaborating for many years in the high performance motorsports sector, particularly in the Formula One world championship, and have developed a long-term partnership based on their respective know-how and experience."

Mecachrome, renowned worldwide for its role in designing, engineering and manufacturing components for both car and aeroplane engines, also prepares the units used in the grand prix-supporting GP2 Series.
