Shyloo Posted September 25, 2020 Posted September 25, 2020 New Ford Puma ST lands with 197bhp The mild-hybrid 1.0-litre three-cylinder turbo petrol engine has been swapped out for the 1.5-litre turbo unit used in the Fiesta ST. Power output is unchanged at 197bhp – 46bhp more than made by the most potent Puma currently available. However, torque has been boosted from 214lb ft to 236lb ft, giving more linear acceleration and enabling the larger and 96kg-heavier Puma ST to match the Fiesta ST’s 0-62mph time of 6.7sec. As in the Fiesta ST, the all-aluminium engine sends its reserves to the front axle via a six-speed manual gearbox. It’s equipped with a radial-axial turbocharger and integrated exhaust manifold for reduced lag, twin-independent variable cam timing and roll-restricting engine mounts designed to improve refinement and cornering performance. While the Puma ST goes without the standard Puma’s mild-hybrid system, cylinder deactivation functionality can shut down an unneeded cylinder in as little as 14 milliseconds, helping to save fuel when coasting or cruising. The Fiesta ST’s active exhaust valve technology also features, but it has been tuned to offer a “more composed cruising experience”, meaning the Puma ST is roughly one decibel quieter. In what Ford is calling a first for the hot crossover segment, the Puma ST also gains a mechanical limited-slip differential, which works alongside a torque-vectoring system to minimise understeer and optimise grip. Further dynamic upgrades come in the form of new ‘force-vectoring springs’ that improve lateral stiffness at the rear, a rear twist beam that’s 50% stiffer than on the standard car and new anti-roll bars at both ends. The steering has been uprated, too, making it nearly 25% quicker than on the standard Puma, while the front brake discs are 17% larger for improved stopping performance. Like the standard Puma, the Puma ST offers Normal, Eco and Sport driving modes, but it swaps the Slippery and Trail functions for a hardcore Track mode, in which the traction control is disabled, the stability control does minimal intervention and all systems are tuned for “the fastest possible lap times” and “the purest driving experience”. An optional performance pack, costing £950, brings a launch control function that improves response off the line and comes with its own dedicated graphical display in the instrument cluster. Like its Focus and Fiesta siblings, the Puma ST features only subtle visual clues to its performance aspirations. At the front, there’s a new front splitter that bears the branding of the Ford Performance division and is said to improve front-end downforce by almost 80%, plus a revised lower grille that improves cooling. The rear end gains a new colour-contrasting diffuser that houses twin tailpipes, and the package is rounded off with a set of bespoke 19in alloy wheels wrapped in specially developed Michelin Pilot Sport 4S performance tyres. The roof, grille, side trims, wing mirrors and roof spoiler of the Puma ST are all finished in gloss-black as standard, while the body can be painted in a new, model-exclusive Mean Green shade. The interior is largely familiar from the standard Puma, but ST-branded Recaro sports seats in the front, bespoke treadplates, a flat-bottomed steering wheel and an ST gearknob set it apart. A wireless smartphone charger, heated windscreen, front and rear parking sensors and smartphone mirroring are all equipped as standard. Modifications to the rear suspension system haven’t affected the Puma’s trademark Megabox storage cubby, which still offers 80 litres of hidden space under the boot floor. Customer deliveries are set to get underway before the end of this year, with efficiency figures due to be published closer to the on-sale date.
