Ford Focus RS Makes Big Power!




Just remember, you heard it (or read it) here first. Ford said that this will be the most powerful Focus ever with "well in excess of 315 hp". Back in February when I posted about it (2016 Focus RS), I brought up the extremely limited edition RS500 which made 345 hp so I expected this one to make close to 350 hp. Sure enough, Ford officially revealed that the Focus RS will make 345 hp and 324 lb-ft of torque from its 2.3 litre EcoBoost engine. This time, though, it won't be a very limited edition to get all that power. All RS's will make that power, at least until Ford makes a performance package or special edition with even more.




As Ford said when it debuted the RS, the engine has been significantly upgraded to handle the added power compared to the 310 hp unit found in the Mustang EcoBoost. The 2.3 litre engine shares the block with the Mustang but significant upgrades support the increased power. The radiator and intercooler are both much bigger units. A new twin-scroll turbo with a larger compressor wheel increases airflow, which is also aided by less restrictive intake and exhaust systems. The exhaust also features an electronically controlled valve that "helps optimize the balance of back pressure and noise output." Typically, such exhaust valves stay closed for quiet operation under light load and open at a certain rpm. To handle the added power, an upgraded alloy is used for the cylinder head to withstand higher temperatures which is also mounted on a head gasket with improved thermal capability. Inside, the cylinder block features stronger high-tensile cast iron liners.

The engine will have a redline of 6,800 rpm and peak torque is available from 2,000 pm to 4,500 rpm and an overboost feature will allow up to 346 lb-ft of torque for 15 seconds at a time. All this power will be routed exclusively through a six speed manual and a torque vectoring AWD system will help put all the power to the pavement. All of this adds up to a very capable package that, on paper, should be vastly superior in performance to its closest competitors, the Golf R and Subaru WRX STi. I'm really looking forward to the first comparison test between all three.
