BMW ford Rs500 (2011)

The Ford Focus RS500 marks the end of production for the current generation Focus RS, with the last vehicles scheduled to leave Ford's Saarlouis Assembly Plant in Germany during September 2010.

While overwhelming customer demand has ensured that total Focus RS output is expected to exceed 11,000 units (significantly more than the 7,000 to 8,000 originally forecast), production of the Ford Focus RS500 will start at Ford's Saarlouis plant in Germany during May 2010 and will be strictly limited to 500 customer vehicles for twenty European markets.

Each Ford Focus RS500 will carry a metal plaque on the centre console, hand-engraved with a unique identification number from 001 to 500.

A small number of pre-production vehicles produced for internal Ford use - such as product development or press demonstrators - will have their own unique numbering scheme, to ensure the exclusivity of the 500 customer cars.

Demand for the Ford Focus RS500 is expected to exceed supply by a considerable margin, and the full production run of just 500 vehicles is being allocated across 20 European markets in line with the anticipated level of interest. For some countries, the very small number of vehicles allocated means the Ford Focus RS500 will, indeed, be a very exclusive purchase for its customers.

Upgraded 350 PS Powertrain

"The more urgent engine sound and sheer thrust of the mid-range performance tell the driver immediately that this is not a standard Focus RS," said Gunnar Herrmann, Ford's Global C-Car Vehicle Line Director. "With 15 per cent more power and the same gutsy, sporting character, our new powertrain gives the Ford Focus RS500 the special engine it deserves."

To provide the Ford Focus RS500 with a fitting power unit, the 305 PS turbocharged Duratec RS 2.5-litre engine from the standard Focus RS has been upgraded to deliver significantly more top-end and mid-range power, but without compromising the base engine's strength and responsiveness at lower revs.

Peak power is increased by 45PS to 350PS at 6,000rpm, while torque has been increased from 440 to 460Nm, delivered across a broad speed range from 2,500 to 4,500rpm.

To achieve the required balance of muscular mid-range and top-end performance, the engine has benefitted from a comprehensive package of enhancements aimed at improving the engine's breathing and combustion.

The changes include a significantly larger air-to-air intercooler to deliver a cooler, denser charge; a larger air filter box for increased airflow; larger diameter exhaust downpipe; and an uprated fuel pump, along with an updated software calibration to optimise the performance of the revised engine.

"The engine's improved breathing has allowed us to increase power without having to raise turbo boost pressure significantly," explained Herrmann. "This has made it possible to enhance peak performance while maintaining the excellent driveability, fuel consumption and emissions of the standard Focus RS."

Preliminary performance figures for the Ford Focus RS500 indicate that it achieves 0-100km/h in 5.6 seconds, with a top speed similar to the 263 km/h in the standard RS.

Engineered by Performance Car Enthusiasts

The Ford Focus RS500 engine has been modified by a team enthusiast engineers from Ford TeamRS in partnership with Revolve Technologies, the automotive engineering firm which develops Ford approved performance upgrades through its Mountune brand.

The shared development and testing programme ensured that the 350 PS Duratec RS engine achieved the specified performance targets while also delivering the standards of durability and serviceability expected by Ford RS customers.

The comprehensive engineering details already developed for the 305 PS Focus RS engine - including a revised cylinder head gasket, ultra-durable metal sprayed cylinder bores, revised pistons and new connecting rods - have ensured that no further mechanical changes were required to cope with the increased performance of the 350 PS Ford Focus RS500 unit.
