Even without the TracKey's race mapping, the Boss engine is significantly modified over a standard Mustang GT's 5 - litre V8, with a
new intake and
new camshafts helping lift power from 412bhp to 444bhp, although curiously the torque drops by 10 lb ft to 380 lb ft.. It's the only car in the test with a manual gearbox and it's a really good one, with the pool ball - topped
gearlever sitting perfectly in the palm of your hand and movement around the gate feeling tight and precise.
The
new dashboard has a classy look and feel, but it's further enhanced by the addition of bespoke VXR dials, a flat - bottomed three - spoke steering wheel with perforated leather rim and a chunky, square - edged
gearlever, which looks distinctive but is uncomfortable to hold.
It also includes a ZF 8 - speed automatic with Quickshift, Block Shifting and wheel - mounted paddleshift, carbon ceramic brakes with enhanced cooling, 420 mm (17 in) front and 356 mm (14 in) rear carbon silicon carbide brake discs, 21 - inch forged alloy wheels, optional titanium exhaust system, updated version of the torque vectoring system from Continental GT3 - R, dynamic system brakes, lowered and stiffened dynamic suspension set - up, front and rear bumper designs incorporating a carbon - fibre splitter and diffuser respectively,
new side sill extensions and bonnet vents in carbon - fibre, gloss - black front wing vents, rifled exhaust tailpipe in gloss - black, dark - tint headlamps and tail - lamps, black - finished brightware at front grilles, lights, rear bumper, door handles and window surrounds; optional aerodynamically balanced rear spoiler and front splitter combination for coupe,
new Supersports badging, 21 - inch forged alloy wheels in black and bright - machined finish, optional side decals optional carbon - fibre engine cover in gloss - finish with Supersports branding, multi-layer hood for convertible, neck warmer for convertible, tri-tone interior option,
new diamond - quilted design at seats and door side panels with Alcantara upholstery, a choice of 11 veneers and technical finishes (including chequered Supersports carbon - fibre fascia panels),
new Supersports emblem stitching, bespoke Supersports steering wheel and unique
gearlever with Alcantara accents.
