Answers:

its Fi (fuel injector) system is high
At its heart is a tuned version of the 130PS 2.0-litre Ford Focus Duratec engine, producing 170PS at 7000rpm and 195Nm of torque from 2500rpm. Transmitted through a Durashift six-speed manual gearbox, this is sufficient to allow the Ford Focus ST170 to achieve 0-62mph in 8.2 seconds and a top speed of 133mph
The 170PS 2.0-litre Duratec ST engine has been developed from the standard 130PS 2.0-litre Ford Focus engine with several new features, including:
· New, high-flow aluminium cylinder head with larger inlet valves and higher lift intake and exhaust camshafts for higher peak rpm levels
· Continuously variable intake valve timing
· High compression, cast-aluminium pistons and forged steel connecting rods
· Dual mass flywheel
· New dual state intake (DSI) manifold, using long runners for low-end torque and shorter runners for higher peak power outputs
