Review: FPV FG.I F6 and F6E (2008-11)

Overview

Released in May 2008, the FPV FG Mk.I (FG.I) F6 Series – initially consisting of the F6 and with the F6 E following in 2009 – were rear-wheel drive, performance sedans. Manufactured in Campbellfield, Victoria, the F6 Series were powered by 4.0-litre turbocharged six cylinder petrol engines that were mated to either six-speed manual or automatic transmissions.

FPV F6 310T engine

The FG F6’s FPV F6 310T engine had a cast iron block, a cast aluminium cylinder head, a Garrett GT35/76R turbocharger which had engine oil-lubricated and water-cooler bearings, an air-to-air intercooler, an electronic single bypass wastegate, double overhead camshafts (DOHC, simplex chain-driven), dual independent variable camshaft timing, four valves per cylinder, Duratec-style finger followers, a dual resonance inlet manifold, coil-on-plug ignition, electronic throttle control, twin knock sensors and a compression ratio of 8.47:1.

Compared to its FPV F6 270T predecessor, the FPV F6 310T engine had:

Strengthened pistons and conrod assemblies;
Revised camshaft timing;
A new, higher efficiency Garrett GT35/76R turbocharger – developed for FPV – which had a larger compressor wheel, different compressor housing, an upgraded wastegate specification and increased boost pressure (0.91 bar, or 13.3 psi);
A lower compression ratio (8.47:1, previously 8.7:1);
A 22 per cent larger intercooler (by core volume) which provided a 45 per cent improvement in heat rejection and a 34 per cent reduction in pressure drop for higher air intake pressure;
A new ‘low loss’ short path air intake system;
A new exhaust manifold; and,
Recalibrated engine management.

Transmissions

The FPV FG F6 was available with six-speed Tremec TR6060 manual or six-speed ZF 6HP26 automatic transmissions.

Replacing the Tremec T56 manual transmission, the Tremec TR6060 had triple synchromesh on first and second gears and double synchromesh on all other gears (including revrese) which reduced gear shift efforts and shift travel. The reduced shift travel also provided increased space for the use of larger, stronger gears for greater durability.

The FPV FG F6 was fitted with the high-performance ZF 6HP26 transmission which was rated for 600 Nm applications and had upgraded clutches with extra plates in the clutch packs. For the FG range, the 6HP26 transmission had a cylinder cut function whereby the fuel injectors would be deactivated during gearshifts to reduce shift times.

Development and dimensions

Developed in conjunction with the FG Falcon , the FPV F6 Series had:

A stronger body structure which made increased use of high-strength steels and ultra high-strength Boron steel and included a new front subframe, additional reinforcement inside the front rails, new high strength floor cross members, transmission tunnel reinforcement and a larger, stronger B-pillar;
New Virtual Pivot Control Link front suspension (described below);
A forward-mounted, Y-shaped steering rack with variable-ratio steering gear;
Upgraded static sealing and triple-sealed doors;
Redesigned fuel tanks; and,
A self-adjusting park brake.

Compared to their BF F6 Typhoon predecessors, the FG F6 Series were 39 mm longer (at 4956 mm), 2 mm narrower (1868 mm), 22 mm taller (1466 mm) and had 7 mm longer wheelbases (2836 mm).

Suspension

The FPV FG F6’s double wishbone front suspension had two lower ball joints that connected the separate lower arms to the suspension knuckle. These two lower links created a virtual pivot of the lower arm – hence the ‘Virtual Pivot Control Link’ name – and allowed the suspension to behave as though the lower pivot point was at the intersection of the two arms. Due to the use of aluminium and high strength steels, the Virtual Pivot Control Link suspension was 22 kg lighter than that in the BF F6 Typhoon .

The FG F6’s independent rear suspension (IRS) had three control arms:

A forged upper control arm;
A stamped front lower control arm; and,
A stamped rear lower control arm.

Each control arm had a cross axis ball joint on the wheel assembly end and was attached to the subframe and knuckle. Furthermore, the ‘Control Blade’ was a stamped trailing arm which provided lateral support and acted as a vertical pivot point.For the FG F6, the roll centre height was increased to reduce in-corner roll and improve straight line stability, while toe-angle was revised to improve steering feel and stability.

The FPV F6 range had Sachs mono-shock dampers front and rear.
