"But the heart of Ford's new musclecar is the all-aluminium V6 motor, with its lower bearing caps cast into the lower crankcase like a motorcycle engine and quad-valve cylinder heads, actuated by twin cams via roller cam followers. The followers run on hydraulic compensators, so you never have to adjust the tappets.
Airflow has been improved from the 2.5-litre motor by a revised intake and a modified fuel system with higher (4.5 bar) operating pressure and increases the fule delivery rate.
This energetic motor is mated to a lightweight Durashift six-speed manual transmission, a completely new development from Ford-Getrag based on a three-shaft design with one input and two output shafts. It has two layshafts with the most commonly used gears – first to fourth – on one with dual synchros and fifth, sixth and reverse on the second layshaft, using a different final drive ratio.
This gives you the best of both worlds, with four short, closely-spaced ratios for hard acceleration and quick work around town and two longer-legged gears for better fuel economy on the open road.
It's similar in effect (although not in operation) to the old British Laycock de Normanville transmission, which gave you an electrically operated overdrive on third and fourth.
It's a lot slicker in operation, however, thanks to a counterbalance that reduces the synchroniser ring resistance felt during gear shifting. The shifting process therefore becomes smoother. The three-shaft layout allows a very compact transmission; the gearbox and clutch assembly weighs only 52kg.
The clutch is also bigger, and it's self-adjusting, which prevents increasing lever pressure as the clutch wears, reduces release-bearing travel and increases the life of the friction plate.
The exhaust system is also specially built for the ST220, with lower exhaust back-pressure (thanks to considerably bigger catalytic converters) increasing the flow of exhaust gases and therefore contributing to improved performance. The whole system, except for the rear exhaust manifold, is made of stainless steel.
Tweaked suspension
The ST220's running gear has been revised to match the increase in power; the chassis has been lowered by 15mm, with shorter, harder springs and tighter shock-absorbers.
Shorter link rods are also used between the suspension strut and the stabiliser bar on the rear axle as a result of the lowered suspension.
The wheelbase has been lengthened, creating more space in the rear of the cabin as an extra dividend, while the track has been widened and crash performance has been improved by means of a modified sub frame.
The lower arms on both axles have been modified to match the increased track and the axles have been isolated from the body to minimise tyre noise inside the car."

Ingen vild gissning...
...är väl att det i så fall är samma Duratec 3,5:a som i nya Edge, och som det snackas om att hamna även i Fusion och syskonbilarna Milan och Zephyr.
I Edge ger den 265 häst, men det är ju X-over bil, så den är förmodligen mappad för låg/mellanvarvsvrid.
