Ford’s shocked fans of its ST-nameplate by revealing a wagon version of the performance Focus at the Frankfurt auto show.The new Focus will be available in hatchback and wagon body-styles, and are all powered by a 2-litre turbocharged engine good for 186kW/360Nm. Despite being 500cc down on a capacity (and configured with a cylinder less), Focus ST’s version of Ford’s four-cylinder turbocharged EcoBoost engine has been impeccably engineered to provide powertrain characteristics similar to the second-generation Focus ST’s iconic Volvo-sourced 2.5-litre five-cylinder.To guarantee hot hatch throttle response from the smaller engine, Ford’s powertrain engineers have equipped the new ST’s 2-litre engine with resigned intake and exhaust systems and a product specific ECU map.Although the characteristic five-cylinder exhaust note is no longer present, Ford’s been cognisant to ensure the new ST does retain an acoustic signature true to its hot hatch heritage. How? Well, there’s a custom crafted exhaust system (that exits below the centre of the rear bumper) and a sound symposer. What’s a sound symposer? Well, it’s a trick harmonics damper that manages to filter out droning road and mechanical noise, whilst allowing more dramatic (and hot hatch desirable) exhaust notes through. TORQUE-STEER MITIGATION...Beyond the smaller (but ostensibly better powertrain), Ford’s new Focus ST retains its front-wheel drive configuration and a host of trick mechanical engineering details to limit torque-steer and ensure a rewarding dynamic driving experience.Although the power steering is electronically assisted, Ford says its suite of torque-steer compensation measures. These include sophisticated torque vectoring (where inner wheel brake applications neaten vehicle posture during high-speed, right radius cornering), and a three-stage ESP system (tallying “on”, “wide-slip” and fully disengaged mode). The new ST also rides 10mm lower than its second-generation predecessor, and rolls (rather disconcertingly, and in a product affliction that Golf GTI owners will have sympathy with) relatively unchanged 18-inch alloys wheels, sporting the familiar split-spoke, five-blade design. FOCUSSED ST: Central exhaust a nice styling change. Tuned to ensure ST-specific acoustic signature is not lost… New Focus ST will be available in three grades: ST1, ST2 and ST3. Obviously, ST1 is the standard model, with cloth-trimmed Recaro seats and keyless start. ST2 adds part-leather Recaros, dual-zone climate control, ST-embossed floor mats, auto illumination and an auto-dimming rear view mirror. The range-topping ST3 features heated, full-leather Recaros, a Recaro rear bench seat, and bi-xenon headlights.1-LITRE ALTERNATIVE?Apart from the new ST, Ford’s also revealed its new 1-litre three-cylinder EcoBoost Focus engine at the 2011 Frankfurt auto show. An amazing powerplant, it’s available in 74- and 88kW versions; both producing 170Nm. Average consumption, in the new Focus bodyshell, averages to 6.2-litres/100km. How does Ford manage such numbers from so little swept capacity? Well, thanks to a twin variable camshaft design and an exhaust manifold cast that is part of the cylinder head. New Focus, whether in family-friendly ST wagon or low-consumption 1-litre triple configuration, has truly become the global car Ford always envisioned it would become…The latest from the Frankfurt show.
