The Invicta S1 is a high-performance and luxurious grand tourer built in the UK since the early 2000s. It’s powered by a range of Ford V8 engines displacing either 4.6 or 5.0L and in its most powerful form develops over 600hp. The latest version of the car turned up recently at a motor show in Brussels sporting a revamped interior including a new 2+2 seating arrangement (former versions were strict two seaters).

The S1 features a one-piece carbon-fibre bodyshell, bonded to a steel tube spaceframe chassis, and forming a lightweight but exceptionally strong monocoque structure. The final kerb weight of the car is 1,380kg. The benefits of the complicated manufacturing process are a car with high flexional and torsional rigidity (for responsive handling) and excellent impact resistance (for high levels of occupant safety).

To improve handling further, engineers positioned the engine and gearbox far back in the chassis and squeezed the fuel tank in between the rear wheels to achieve a close to the ideal 50/50 weight distribution.

Sending power to the rear wheels is a five-speed manual manufactured by Borg-Warner and an Australian-built BTR hydratak viscous-coupling racing limited-slip differential. A six speed manual is also available. With all this performance it’s little wonder that the S1 in 600 guise can accelerate to 60mph in just under four seconds and reach a top speed in excess of 200mph.
