That 1.5-litre turbo is an all-aluminium three-cylinder lump, the first time a Ford Performance car has had just three pistons. It's rated at 200hp and 214lb ft (there's no mention of overboost just yet), sufficient for a 6.7-second 0-62mph sprint. More interestingly though, this engine will have cylinder deactivation. Yep, cylinder deactivation on a three-cylinder engine. When full performance isn't needed, fuel delivery and valve operation is closed and it runs on two cylinders. The process takes just 14 milliseconds to both close off a cylinder and bring the engine back to three, contributing to projected CO2 emissions of 114g/km.
Chassis-wise it could be argued very little needed to change for the ST. Despite that, Ford has tweaked the Torque Vectoring Control (the system that brakes an inside wheel for better traction) plus the ESC now has three modes: on, "wide-slip mode with limited intervention" and fully off. Beyond that nothing additional has yet been confirmed.
standard Fiesta, this new ST will offer buyers a wider range of personalisation. There are "a range of trim elements" for the gearstick, wheel, door pulls and "decorative dashboard spear"; additional styling packs will also be offered, alongside a new Liquid Blue paint option. And praise be, the ST has new infotainment. SYNC3 has voice control and an eight-inch touchscreen as well as CarPlay and Android Auto compatibility. There's a B&O Play optional stereo too.
It's a pretty comprehensive overhaul for the fastest Fiesta then, without even mentioning the "bold and distinctive exterior styling". Following a Geneva debut the new ST will be launched as a three- and five-door in early 2018. Time to bag a great deal on the outgoing one now!
